Walkthrough

Replaces local UI state in the add-money onramp flow with URL-persisted query state using nuqs, wraps app providers with NuqsAdapter, and refactors OnrampFlowContext to remove UI state exposing transient onramp data and flags.

Changes

Cohort / File(s)	Summary
Dependencies & App Provider package.json, src/app/ClientProviders.tsx	Added nuqs@^2.8.6 and wrapped provider tree with NuqsAdapter (next/app) to enable URL query state management.
Mobile bank page (URL-driven flow) src/app/(mobile-ui)/add-money/[country]/bank/page.tsx	Replaced local step/amount with useQueryStates (step, amount), derive initial step from KYC/user when absent, persist all step transitions and amount edits to URL, and update loading/redirect logic to depend on URL state.
AddMoney components (amount & step sync) src/components/AddMoney/components/AddMoneyBankDetails.tsx, src/components/AddMoney/components/InputAmountStep.tsx, src/components/AddMoney/components/MantecaAddMoney.tsx, src/app/(mobile-ui)/add-money/[country]/[regional-method]/page.tsx	AddMoneyBankDetails: source amount from URL query for add-money flow. InputAmountStep: broadened setTokenAmount prop type and added optional initialDenomination and setDisplayedAmount props. MantecaAddMoney: moved step/amount/currency to URL state, added URL-synced handlers, validation, query invalidation on step change, removed source prop (component no longer accepts props). Regional method page updated to call <MantecaAddMoney /> without source.
Manteca deposit UI changes src/components/AddMoney/components/MantecaDepositShareDetails.tsx	Removed public source and onBack props; NavHeader now uses router.back() directly for previous navigation.
AmountInput public API src/components/Global/AmountInput/index.tsx	Added initialDenomination?: string and setDisplayedAmount?: (value: string) => void to AmountInput props; initial symbol selection honors initialDenomination, and setDisplayedAmount is invoked when display value updates.
Rhino deposit view typing src/components/AddMoney/views/RhinoDeposit.view.tsx	Added explicit type annotation for refetchInterval callback parameter (typing/formatting only).
Onramp flow context refactor src/context/OnrampFlowContext.tsx	Removed OnrampView type and UI state fields (amountToOnramp, currentView and their setters); exposed fromBankSelected, onrampData, their setters, and resetOnrampFlow; updated provider value and docs to reflect URL-based step management.

@jjramirezn, I've completed an in-depth review of this PR. Here are my findings:

🚨 Critical Issues

1. Missing Data Validation for Deep Links

Risk: HIGH - Can cause runtime errors

In src/app/(mobile-ui)/add-money/[country]/bank/page.tsx, the showDetails step renders AddMoneyBankDetails without validating that onrampData exists:

if (urlState.step === 'showDetails') {
    return <AddMoneyBankDetails />
}

Problem: If a user navigates directly to ?step=showDetails (via bookmark, manual URL edit, or browser back button), onrampData will be null, causing the component to fail since it expects onrampData.depositInstructions.

Recommendation:

if (urlState.step === 'showDetails') {
    if (!onrampData?.transferId) {
        // Redirect back to input step if data is missing
        setUrlState({ step: 'inputAmount', amount: rawTokenAmount || null })
        return <PeanutLoading />
    }
    return <AddMoneyBankDetails />
}

2. Merge Artifact File Committed

Risk: HIGH - Repository hygiene

The file src/app/(mobile-ui)/points/page.tsx.orig should not be committed. This is a merge conflict artifact.

Action Required: Delete this file before merging.

3. Amount Validation Can Be Bypassed

Risk: MEDIUM - Business logic

Users can manually set ?amount=0.01 in the URL to bypass minimum amount validations and proceed to create an onramp with invalid amounts. While the backend should validate, client-side validation can be circumvented.

Recommendation: Add validation in the showDetails step render guard:

if (urlState.step === 'showDetails') {
    // Validate amount is still within bounds
    const amount = parseFloat(rawTokenAmount)
    if (!amount || amount < minimumAmount) {
        setUrlState({ step: 'inputAmount' })
        setError({ showError: true, errorMessage: 'Invalid amount' })
        return <PeanutLoading />
    }
    // ... rest of validation
}

⚠️ Medium Risks

4. Inconsistent State Management Pattern

The request fulfillment flow (RequestFulfillmentFlowContext) still uses context-based state management, while the main add-money flow now uses URL state. This creates maintenance burden and confusing patterns for developers.

Recommendation: Consider migrating request fulfillment flow to URL state in a follow-up PR for consistency.

5. Browser Navigation Edge Cases

Risk: MEDIUM

When users click browser back button:

• They'll move to a previous step
• But local state (e.g., depositDetails, liveKycStatus) may be stale or incorrect
• API responses stored in context won't be refreshed

Current mitigation: The code does check for onrampData existence, but consider adding explicit refresh logic when navigating back to certain steps.

6. No Migration for Existing Sessions

If users have in-flight sessions with data in the old context structure, this change will lose that data. Consider the impact on active users during deployment.

✅ Positive Aspects

1. Better UX: Users can bookmark specific steps, share URLs, and use browser back/forward naturally
2. Performance: Likely improved since URL state changes won't cause unnecessary context re-renders
3. Type Safety: Good use of parseAsStringEnum to ensure only valid steps/currencies
4. Code Documentation: Excellent comments explaining the URL state pattern and rationale
5. Consistent Implementation: Both bank and Manteca flows updated similarly

🎯 Code Quality & DRY

Duplication

There's some duplication between bank/page.tsx and MantecaAddMoney.tsx:

• URL state setup pattern
• Step validation logic
• Amount handling callbacks

Recommendation: Extract a custom hook:

// hooks/useAddMoneyUrlState.ts
export function useAddMoneyUrlState<TStep extends string>(
  validSteps: TStep[],
  defaultStep: TStep
) {
  const [urlState, setUrlState] = useQueryStates({
    step: parseAsStringEnum(validSteps),
    amount: parseAsString,
  }, { history: 'push' })
  
  const step = urlState.step ?? defaultStep
  const amount = urlState.amount ?? ''
  
  return { step, amount, setUrlState }
}

Minor Issues

• Line 58 in RhinoDeposit.view.tsx: Unnecessary type annotation change (query: { state: { data?: { status?: string } } }) - this appears unrelated to the PR's purpose
• InputAmountStep.tsx Line 17: Type signature change for setTokenAmount is good but could use a comment explaining why it accepts both forms

⚡ Performance Impact

Assessment: NEUTRAL to SLIGHTLY POSITIVE

• Positive: URL state changes don't trigger context consumer re-renders
• Positive: Less prop drilling through component tree
• Neutral: nuqs library is lightweight (~3.5KB gzipped)
• Neutral: No additional network requests introduced

Latency: No measurable latency impact expected.

🧪 Concise QA Testing Guide

Happy Path Testing

1. Basic Flow - Mexico Bank

   • Navigate to /add-money/mexico/bank
   • Should start at step=inputAmount
   • Enter amount: 500 MXN
   • Verify URL updates to ?step=inputAmount&amount=500
   • Click Continue → verify KYC or showDetails step appears
   • Check URL reflects current step

2. Manteca Flow - Argentina

   • Navigate to /add-money/argentina/manteca
   • Enter 100 USD
   • Change currency to ARS
   • Verify URL has ?step=inputAmount&amount=100&currency=ARS
   • Complete KYC if needed
   • Verify deposit details appear with correct currency

3. US Bank Flow

   • Navigate to /add-money/us/bank
   • Verify direct deposit details page loads correctly
   • Check amount displays properly

Edge Cases & Risk Testing

4. URL Manipulation

   • Navigate to /add-money/mexico/bank?step=showDetails
   • Expected: Should redirect to inputAmount (after fix)
   • Currently: Likely crashes ❌

5. Invalid Amount in URL

   • Navigate to /add-money/mexico/bank?step=inputAmount&amount=0.01
   • Try to proceed
   • Expected: Should show minimum amount error

6. Browser Navigation

   • Complete flow to showDetails
   • Click browser back button
   • Verify: Previous step loads correctly
   • Verify: Amount is still populated
   • Click forward button
   • Verify: Returns to showDetails gracefully

7. Deep Linking

   • Bookmark /add-money/mexico/bank?step=kyc&amount=500
   • Open bookmark in new session
   • Expected: Should handle gracefully (redirect or request auth)

8. Invalid Step in URL

   • Navigate to /add-money/mexico/bank?step=invalidStep
   • Expected: Should default to inputAmount
   • Verify: parseAsStringEnum handles this correctly

9. Currency Validation

   • Navigate to /add-money/argentina/manteca?currency=INVALID
   • Expected: Should default to USD
   • Try proceeding with deposit

10. Concurrent Tab Testing

    • Open flow in two tabs
    • Complete step in Tab 1
    • Switch to Tab 2
    • Verify: State doesn't interfere between tabs

Regression Testing

11. Request Fulfillment Flow

    • Test bank request fulfillment still works (uses old context pattern)
    • Verify no interference between the two patterns

12. Existing Context Consumers

    • Test AddWithdrawRouterView still works
    • Verify setFromBankSelected functionality intact

📋 Recommendations Summary

1. CRITICAL: Add validation guards for showDetails step
2. CRITICAL: Delete .orig file
3. HIGH: Add amount validation in step render guards
4. MEDIUM: Extract shared URL state logic into custom hook
5. MEDIUM: Consider consistency with request fulfillment flow
6. LOW: Add integration tests for this critical flow
7. LOW: Document the URL state pattern in architecture docs

---

Overall Assessment: This is a well-intentioned refactor that improves UX through URL state management, but it has HIGH RISK of runtime errors due to missing validation guards. The code quality is good with excellent documentation, but the lack of data validation for deep links is a critical gap that must be addressed before merging.

Would you like me to create issues for the follow-up items, or shall I provide complete code fixes for the critical issues?

Caution

Some comments are outside the diff and can’t be posted inline due to platform limitations.

⚠️ Outside diff range comments (1)

src/components/AddMoney/components/MantecaAddMoney.tsx (1)

220-228: Redirect to inputAmount when depositDetails is missing to handle navigation back scenarios.

When a user navigates directly to ?step=depositDetails via browser history, deep link, or page refresh, depositDetails local state will be undefined while the URL step persists. The condition at line 220 prevents rendering, but the component returns null at line 230 instead of gracefully redirecting.

Add a useEffect to redirect back to inputAmount when step === 'depositDetails' but depositDetails is missing, ensuring consistent UX for these navigation scenarios.

🧹 Nitpick comments (2)

src/app/(mobile-ui)/points/page.tsx.orig (2)

65-68: Missing dependency in useEffect.

fetchUser is called inside useEffect but not included in the dependency array. While this may be intentional for mount-only behavior, it can cause issues if fetchUser reference changes.

🔎 Consider adding fetchUser to dependencies or using a ref

     useEffect(() => {
         // Re-fetch user to get the latest invitees list for showing heart Icon
         fetchUser()
-    }, [])
+    }, [fetchUser])

If mount-only behavior is truly needed, consider using a ref to track if the effect has run.

109-121: Complex inline calculation could benefit from extraction.

The progress bar width calculation is complex with multiple conditions. Consider extracting to a named function or useMemo for readability.

🔎 Suggested extraction

const progressBarWidth = useMemo(() => {
    if (tierInfo?.data.currentTier >= 2) return 100
    if (tierInfo.data.nextTierThreshold <= 0) return 0
    
    const ratio = Math.min(1, tierInfo.data.totalPoints / tierInfo.data.nextTierThreshold)
    return Math.pow(ratio, 0.6) * 100

src/context/OnrampFlowContext.tsx (3)

29-41: Good documentation for the architectural decision.

The documentation clearly explains the separation of concerns: URL-managed state (step/amount via nuqs) vs Context-managed state (transient error, navigation flag, API data). This aids maintainability and aligns with the principle of using URL state for shareable/bookmarkable values.

---

54-72: LGTM!

The state initialization and reset logic are correct. The empty dependency array in useCallback is appropriate since the state setters from useState are stable references. The reset function properly clears all context-managed state.

---

74-85: LGTM!

The useMemo dependencies are correct. State values and the memoized resetOnrampFlow callback are included, while the stable useState setters are appropriately omitted.

package.json (1)

64-64: LGTM!

The nuqs library is a well-maintained choice for URL state management in Next.js applications. Version 2.8.x is compatible with Next.js 15+ and React 19.

src/app/ClientProviders.tsx (1)

Correct integration of NuqsAdapter for the Next.js App Router. Placing it as the outermost wrapper ensures URL state is available throughout the component tree.

20-20: LGTM!

Appropriate import for read-only URL state consumption in the bank details view.

29-31: Good documentation of URL state source.

Clear comments explaining the data source selection pattern (URL for add-money, context for request-fulfillment). This helps maintainability.

---

79-82: LGTM!

The conditional amount sourcing is clean:

• amountFromUrl ?? '' for add-money flow (URL-driven)
• depositInstructions.amount for request-fulfillment flow (context-driven)

This aligns with the broader URL-state architecture in this PR.

src/components/AddMoney/components/MantecaAddMoney.tsx (2)

39-51: LGTM!

Well-structured URL state management with:

• Type-safe enum parsing for step and currency
• history: 'push' enabling browser back/forward navigation
• Sensible defaults when URL params are absent

---

Good implementation of URL-synced handlers:

39-48: LGTM!

Well-structured URL state setup with:

• Type-safe step enum covering the full flow
• Amount as a simple string
• history: 'push' for proper navigation

---

100-116: Good deep-linking support with careful initialization.

The pattern of checking urlState.step before setting initial step correctly supports:

• Deep linking (respects existing URL step)
• Fresh navigation (derives from KYC status)
• Waiting for user fetch before deciding

---

267-283: Good loading state handling during initialization.

Proper handling of the loading state while:

1. User is being fetched (user === null)
2. Initial step is being determined (!urlState.step)

This prevents flash of wrong content during initialization.

---

59-59: setError is actively used and necessary for validation; verify cleanup strategy for onrampData.

setError is used extensively throughout the component for amount validation (lines 128, 133, 137, 140, 158, 172, 190, 198), so it's not unused. setOnrampData is correctly called on line 185 to store the API response and is needed by the subsequent AddMoneyBankDetails component.

However, the component never calls resetOnrampFlow() on unmount or when navigating away from the entire onramp flow. If users navigate back to /add-money or elsewhere, stale onrampData persists in the context. Clarify whether this is intentional (to support re-entry into the flow) or if cleanup is needed.

Likely an incorrect or invalid review comment.

🧹 Nitpick comments (3)

src/components/AddMoney/components/MantecaAddMoney.tsx (1)

81-95: Amount validation effect is correct, but consider adding a guard in the submit handler.

The validation correctly checks against MIN_MANTECA_DEPOSIT_AMOUNT and MAX_MANTECA_DEPOSIT_AMOUNT. However, handleAmountSubmit (line 131) doesn't re-validate before calling the API. If a user deep-links with an invalid amount and clicks submit before the validation effect runs, the API call could proceed with an invalid amount.

Consider adding an early return in handleAmountSubmit:

🔎 Suggested guard in handleAmountSubmit

 const handleAmountSubmit = useCallback(async () => {
     if (!selectedCountry?.currency) return
     if (isCreatingDeposit) return
+    
+    // Re-validate amount before submitting
+    const paymentAmount = parseUnits(usdAmount || '0', PEANUT_WALLET_TOKEN_DECIMALS)

The pattern is correct. As noted in PR comments, there's opportunity to extract shared URL state logic into a custom hook to reduce duplication between this file and MantecaAddMoney.tsx.

🔎 Example shared hook signature

// hooks/useAddMoneyUrlState.ts
type AddMoneyStep = 'inputAmount' | 'kyc' | 'collectUserDetails' | 'showDetails' | 'depositDetails'

export function useAddMoneyUrlState<T extends AddMoneyStep>(
  allowedSteps: T[],
  options?: { includeCurrency?: boolean }
) {
  // Shared URL state logic
}

Learning: In the peanut-ui codebase, `window.history.replaceState` is preferred over `router.replace` when immediate/synchronous URL parameter updates are required, as `router.replace` is asynchronous and doesn't guarantee instant URL changes that subsequent code can rely on. This pattern is used consistently across usePaymentInitiator.ts, Confirm.payment.view.tsx, and useClaimLink.tsx.

When the slider is used with `maxAmount`, the `selectedAmount` is computed in USD and `isInputUsd` is always `true`, so the conversion in `onChange` handles it correctly.

🔇 Additional comments (7)

src/components/AddMoney/components/MantecaAddMoney.tsx (3)

20-26: Well-structured type definitions for URL state.

Good use of parseAsStringEnum for type-safe step and currency parsing. The types are clear and self-documenting.

Consider extracting MantecaStep and CurrencyDenomination to a shared types file if they're needed elsewhere, or if you want to share patterns with the bank flow.

---

37-51: URL state setup looks good.

The use of history: 'push' enables proper browser navigation, and the derived values with defaults (lines 49-51) provide a clean API for consumers.

---

111-129: Handlers correctly sync state to URL.

Good defensive validation in handleDenominationChange to ensure only valid currencies are persisted. Using null to remove empty values from URL is the correct nuqs pattern.

src/app/(mobile-ui)/add-money/[country]/bank/page.tsx (4)

100-116: Initial step determination logic is well-designed.

Good approach to:

1. Respect existing URL step (enabling deep links)
2. Wait for user data before determining initial step
3. Route based on KYC status

The effect correctly includes urlState.step in dependencies to prevent re-running after step is set.

---

146-162: Amount handling is correctly implemented.

The handler uses null to remove empty values from URL, and the validation effect properly validates on change. The separation of concerns is clean.

---

266-283: Loading state handling is appropriate.

The two loading checks serve different purposes:

1. Lines 267-269: Initial load while fetching user with no URL step
2. Lines 281-283: Fallback while determining initial step

This prevents flickering and ensures smooth UX during initialization.

---

260-264: KYC modal opening correctly triggered via effect.

Unlike the showDetails guard, this correctly uses useEffect to trigger side effects (modal opening) based on URL state.

src/app/(mobile-ui)/add-money/[country]/bank/page.tsx (1)

100-116: Consider extracting initial step logic to a shared hook.

This initial step determination pattern (respecting URL state, waiting for user data, routing based on KYC status) is likely duplicated across add-money flows. Extracting it to a shared hook would improve maintainability and consistency.

Example structure:

// hooks/useOnrampInitialStep.ts
function useOnrampInitialStep(currentStep: string | null, kycStatus: BridgeKycStatus | undefined) {
  // Returns initial step and loading state
}

src/components/AddMoney/components/MantecaAddMoney.tsx (3)

39-46: Consider history: 'replace' to avoid polluting browser history.

Using history: 'push' creates a new browser history entry for every URL state change, including each keystroke when typing an amount. This can make the browser back button cumbersome for users. For intermediate UI states like amount and currency, consider using history: 'replace' instead.

🔎 Suggested change

     const [urlState, setUrlState] = useQueryStates(
         {
             step: parseAsStringEnum<MantecaStep>(['inputAmount', 'depositDetails']),
             amount: parseAsString,
             currency: parseAsStringEnum<CurrencyDenomination>(['USD', 'ARS', 'BRL', 'MXN', 'EUR']),
         },
-        { history: 'push' }
+        { history: 'replace' }
     )

---

119-129: Extract valid currencies to avoid duplication.

The validCurrencies array duplicates the CurrencyDenomination type definition (line 26). If the type is updated, this array must be manually synchronized, creating a maintenance burden.

🔎 Suggested refactor

Extract the valid currencies to a shared constant at the top of the file:

 // Currency denomination type for URL state
 type CurrencyDenomination = 'USD' | 'ARS' | 'BRL' | 'MXN' | 'EUR'
+const VALID_CURRENCIES: CurrencyDenomination[] = ['USD', 'ARS', 'BRL', 'MXN', 'EUR']

131-177: Add explicit validation before non-null assertion on amount.

Line 152 uses amount! with a non-null assertion operator, but if both usdAmount and currencyAmount are empty/undefined, this could pass an invalid value to the API. While the UI likely prevents this scenario, adding an explicit guard improves code safety and clarity.

🔎 Suggested guard

     const handleAmountSubmit = useCallback(async () => {
         if (!selectedCountry?.currency) return
         if (isCreatingDeposit) return
 
+        // Validate we have a valid amount
+        if (!usdAmount || usdAmount === '0.00' || error) {
+            return
+        }
+
         // check if we still need to determine KYC status
         if (isMantecaKycRequired === null) {
             // still loading/determining KYC status, don't proceed yet
             return
         }

Learning: In the peanut-ui codebase, `window.history.replaceState` is preferred over `router.replace` when immediate/synchronous URL parameter updates are required, as `router.replace` is asynchronous and doesn't guarantee instant URL changes that subsequent code can rely on. This pattern is used consistently across usePaymentInitiator.ts, Confirm.payment.view.tsx, and useClaimLink.tsx.

Learning: In the KYC flow implementation, `setJustCompletedKyc` must be called after `await fetchUser()` in the `handleKycSuccess` callback.

28-48: Clean URL state setup with nuqs.

The URL state management is well-structured with proper type safety and enum validation for steps. Using 'push' history mode enables browser navigation, and parsing amount as string is appropriate for decimal inputs.

---

266-271: Excellent fix for deep-link validation.

This useEffect properly guards against accessing showDetails without required onramp data, addressing the critical issue from the previous review. The redirect to inputAmount with the loading state check below (lines 335-339) provides a smooth user experience for deep-link and back-navigation scenarios.

Based on the commit message and PR objectives, this fix successfully prevents crashes when showDetails is accessed directly via deep link or browser navigation.

src/components/AddMoney/components/MantecaAddMoney.tsx (5)

97-102: LGTM - Query invalidation is appropriate.

Invalidating the transactions query when entering the deposit details step ensures users see fresh data. The dependencies are correct.

---

186-191: LGTM - Proper handling of deep link and back navigation edge case.

This useEffect correctly addresses the previous review concern about state updates during render. By moving the redirect logic to useEffect, it prevents React warnings and potential render loops while safely guarding against accessing depositDetails without required data.

---

227-231: LGTM - Safe render guard complements the redirect useEffect.

Returning null when depositDetails is missing prevents any attempt to render with incomplete data while the redirect useEffect executes. This pattern correctly handles the deep-link edge case.

---

37-51: URL state pattern is well-implemented for this POC.

The URL-based state management using nuqs is clean and type-safe. The separation between URL-persisted state (step, amount, currency) and transient local state (depositDetails, error, loading) is appropriate. The inline documentation at lines 37-38 showing example URLs is helpful for maintainability.

---

82-95: The error state is already handled via the submit button's disabled state.

The InputAmountStep component properly disables the submit button when an error exists (line 71: disabled={!!error || isLoading || !parseFloat(tokenAmount)}). This prevents handleAmountSubmit from being triggered through the UI when validation fails. An explicit error check in handleAmountSubmit would be redundant given the button-level protection already in place.

139-178: Critical: Add server-side or synchronous validation before API call to prevent amount bypass.

As noted in PR objectives, users can deep-link with tiny amounts (e.g., ?amount=0.01&currency=USD) and potentially bypass client-side validation. The validation effect on lines 83-96 runs asynchronously on usdAmount changes, but there's a race window where the submit button could be clicked before the USD equivalent is calculated and validated.

Add synchronous validation in handleAmountSubmit before the API call:

🔎 Proposed fix

 const handleAmountSubmit = useCallback(async () => {
     if (!selectedCountry?.currency) return
     if (isCreatingDeposit) return
+    
+    // Validate amount before proceeding (synchronous check to prevent bypass)

🧹 Nitpick comments (3)

src/components/Global/AmountInput/index.tsx (1)

133-149: Consider adding setDisplayedAmount to the dependency array.

The setDisplayedAmount callback is used inside this effect but not listed in the dependency array. If the parent component recreates this callback on re-render (e.g., without useCallback), the effect may use a stale reference.

🔎 Proposed fix

-    }, [displayValue, alternativeDisplayValue, displaySymbol, secondaryDenomination])
+    }, [displayValue, alternativeDisplayValue, displaySymbol, secondaryDenomination, setDisplayedAmount])

src/components/AddMoney/components/MantecaAddMoney.tsx (2)

199-209: Verify prop mapping between tokenAmount/setTokenAmount and actual values.

The naming is potentially confusing:

• tokenAmount={displayedAmount} - this is the displayed value (could be ARS, USD, etc.)
• setTokenAmount={handleUsdAmountChange} - but this handler sets USD amount

This asymmetry (display value in, USD value out) relies on AmountInput passing the secondary (USD) amount to setSecondaryAmount. While functionally correct, consider renaming for clarity or adding a comment explaining the mapping.

---

51-53: Consider initializing usdAmount from URL state when denomination is USD.

If a user deep-links with ?amount=100&currency=USD, usdAmount starts empty and only gets populated after AmountInput mounts and triggers its effect. This contributes to the validation timing gap.

🔎 Proposed fix

-    // Local UI state for tracking both amounts (needed for API call and validation)
-    const [usdAmount, setUsdAmount] = useState<string>('')
-    const [localCurrencyAmount, setLocalCurrencyAmount] = useState<string>('')
+    // Local UI state for tracking both amounts (needed for API call and validation)
+    // Initialize from URL state if available and denomination matches
+    const [usdAmount, setUsdAmount] = useState<string>(() => 
+        currentDenomination === 'USD' ? (urlState.amount ?? '') : ''
+    )
+    const [localCurrencyAmount, setLocalCurrencyAmount] = useState<string>(() =>
+        currentDenomination !== 'USD' ? (urlState.amount ?? '') : ''
+    )

Learning: In the peanut-ui codebase, `window.history.replaceState` is preferred over `router.replace` when immediate/synchronous URL parameter updates are required, as `router.replace` is asynchronous and doesn't guarantee instant URL changes that subsequent code can rely on. This pattern is used consistently across usePaymentInitiator.ts, Confirm.payment.view.tsx, and useClaimLink.tsx.

Timestamp: 2025-09-18T09:30:42.901Z
Learning: In src/app/(mobile-ui)/withdraw/page.tsx, the useEffect that calls setShowAllWithdrawMethods(true) when amountFromContext exists is intentionally designed to run only on component mount (empty dependency array), not when amountFromContext changes. This is the correct behavior for the withdraw flow where showing all methods should only happen on initial load when an amount is already present.

🔇 Additional comments (8)

src/components/AddMoney/components/MantecaDepositShareDetails.tsx (1)

20-27: Props simplified to align with URL-driven navigation - LGTM.

The removal of source and onBack props in favor of router.back() is appropriate for the URL-state pattern. Since navigation state is now persisted in the URL, router.back() will correctly restore the previous step.

Also applies to: 85-85

src/app/(mobile-ui)/add-money/[country]/[regional-method]/page.tsx (1)

18-18: Prop removal aligns with component signature change - LGTM.

The removal of source="regionalMethod" is consistent with MantecaAddMoney becoming a prop-less component that derives its state from URL params.

src/components/AddMoney/components/InputAmountStep.tsx (2)

17-17: Type widening for setTokenAmount is appropriate.

The union type ((value: string) => void) | React.Dispatch<React.SetStateAction<string>> allows both simple callback handlers and React state setters, supporting the URL-driven pattern while maintaining backward compatibility.

---

22-23: New props for URL-state integration forwarded correctly - LGTM.

The initialDenomination and setDisplayedAmount props are properly accepted and forwarded to AmountInput, enabling the parent component to control initial state and track displayed values for URL synchronization.

Also applies to: 35-36, 50-55

src/components/Global/AmountInput/index.tsx (1)

71-83: Initial denomination logic is well-implemented.

The lazy initializer correctly validates initialDenomination against available denominations and falls back to primaryDenomination.symbol when invalid or not provided. This prevents URL state with invalid currency values from causing issues.

src/components/AddMoney/components/MantecaAddMoney.tsx (3)

20-49: URL state setup using nuqs looks good.

The use of parseAsStringEnum for type-safe step and currency values, combined with history: 'push' for browser navigation support, is well-suited for the deep-link and bookmarking requirements. Based on learnings, this aligns with the codebase preference for URL state when synchronous updates are needed.

---

187-192: Good: Redirect logic moved to useEffect as suggested in past review.

This correctly addresses the previous review comment about state updates during render. The redirect now runs as a side effect rather than during the render phase.

---

230-236: Good defensive guard for missing deposit details.

The if (!depositDetails) return null guard prevents rendering MantecaDepositShareDetails without required data. Combined with the useEffect redirect on lines 187-192, this provides defense-in-depth against invalid deep-link states.

@Hugo0, I've completed a fresh in-depth review of the current state of PR 1602. Here's my comprehensive assessment:

🎉 Improvements Since Last Review

Great progress! Several critical issues have been addressed:

1. ✅ Merge artifact removed - page.tsx.orig file is gone
2. ✅ Deep-link validation added - Both flows now have proper guards:
   • Bank flow (lines 268-271): useEffect redirects to inputAmount if showDetails accessed without onrampData
   • Manteca flow: Similar pattern for depositDetails step
3. ✅ Render guards in place - Shows loading state while redirecting

🚨 Risk Assessment: MEDIUM (reduced from HIGH)

Remaining Risk Areas

1. Amount Validation Still Bypassable (MEDIUM Risk)

Current state: Input validation exists, but URL manipulation still possible.

// Line 136-138: Validates on input
if (amount && amount < minimumAmount) {
    setError({ showError: true, errorMessage: `Minimum deposit is ${minimumAmount}.` })
    return false
}

Problem: User can manually edit URL to ?amount=0.01&step=showDetails and the useEffect redirect only checks for onrampData existence, not amount validity.

Recommendation: Add amount validation to the redirect guard:

useEffect(() => {
    if (urlState.step === 'showDetails') {
        const amount = parseFloat(rawTokenAmount)
        if (!onrampData?.transferId || !amount || amount < minimumAmount) {
            setUrlState({ step: 'inputAmount' })
            if (amount && amount < minimumAmount) {
                setError({ showError: true, errorMessage: `Minimum deposit is ${minimumAmount}.` })
            }
        }
    }
}, [urlState.step, onrampData?.transferId, setUrlState, rawTokenAmount, minimumAmount])

2. Browser Navigation Edge Cases (LOW-MEDIUM Risk)

When users use browser back/forward:

• URL state updates immediately
• But context state (onrampData, depositDetails) may be stale
• Current mitigation is adequate (redirect guards) but could cause momentary flashing

3. Inconsistent Pattern - Request Fulfillment Flow (MEDIUM Risk)

RequestFulfillmentFlowContext still uses enum-based step management:

export enum RequestFulfillmentBankFlowStep {
    BankCountryList = 'bank-country-list',
    DepositBankDetails = 'deposit-bank-details',
    OnrampConfirmation = 'onramp-confirmation',
    CollectUserDetails = 'collect-user-details',
}

This creates:

• Two different mental models for developers
• Potential for confusion when maintaining/extending
• Mixed state patterns in the same codebase area

Impact: Maintenance burden, increased cognitive load, harder onboarding for new developers.

4. No Error Boundaries (LOW Risk)

If URL state parsing fails or nuqs encounters issues, there's no graceful degradation. Consider wrapping add-money routes in error boundaries.

5. No Test Coverage (MEDIUM Risk)

Zero tests found for these critical flows. This increases regression risk significantly.

⚡ Performance Impact: NEUTRAL to SLIGHTLY POSITIVE

Positive Impacts

• Fewer re-renders: URL state changes don't trigger context consumer re-renders
• Lightweight library: nuqs is ~3.5KB gzipped
• No additional network requests: URL parsing is synchronous

Neutral Impacts

• Browser history operations: history: 'push' adds entries, but this is expected behavior
• Parse overhead: Minimal - parseAsString and parseAsStringEnum are simple operations

Performance Measurements

No measurable latency regression expected. URL updates are instant, and the validation guards prevent unnecessary API calls.

Assessment: ✅ Performance impact is positive overall.

🎨 Code Quality & DRY: GOOD with Missed Opportunities

Positive Aspects

1. Excellent documentation: Clear comments explaining URL state pattern

   // URL state - persisted in query params
   // Example: /add-money/mexico/bank?step=inputAmount&amount=500

2. Type safety: Good use of parseAsStringEnum with TypeScript types

   type BridgeBankStep = 'inputAmount' | 'kyc' | 'collectUserDetails' | 'showDetails'

3. Consistent validation pattern: Both flows use useEffect + render guards

4. Separation of concerns: URL state separate from business logic state

DRY Violations (MEDIUM Priority)

Duplication detected between bank/page.tsx and MantecaAddMoney.tsx:

Both files have nearly identical:

const [urlState, setUrlState] = useQueryStates(
    {
        step: parseAsStringEnum<StepType>([...steps]),
        amount: parseAsString,
    },
    { history: 'push' }
)

// Redirect guard pattern
useEffect(() => {
    if (urlState.step === 'targetStep' && !requiredData) {
        setUrlState({ step: 'inputAmount' })
    }
}, [urlState.step, requiredData, setUrlState])

Recommendation: Extract shared logic:

// hooks/useAddMoneyUrlState.ts
export function useAddMoneyUrlState<TStep extends string>({
    validSteps,
    defaultStep,
    additionalParams = {}
}: {
    validSteps: TStep[]
    defaultStep: TStep
    additionalParams?: Record<string, any>
}) {
    const [urlState, setUrlState] = useQueryStates(
        {
            step: parseAsStringEnum<TStep>(validSteps),
            amount: parseAsString,
            ...additionalParams,
        },
        { history: 'push' }
    )
    
    const step = urlState.step ?? defaultStep
    const amount = urlState.amount ?? ''
    
    return { 
        step, 
        amount, 
        urlState,
        setUrlState,
        rawAmount: urlState.amount 
    }
}

// Usage in bank/page.tsx
const { step, amount, setUrlState } = useAddMoneyUrlState({
    validSteps: ['inputAmount', 'kyc', 'collectUserDetails', 'showDetails'] as const,
    defaultStep: 'inputAmount'
})

// Usage in MantecaAddMoney.tsx
const { step, amount, setUrlState } = useAddMoneyUrlState({
    validSteps: ['inputAmount', 'depositDetails'] as const,
    defaultStep: 'inputAmount',
    additionalParams: {
        currency: parseAsStringEnum<CurrencyDenomination>(['USD', 'ARS', 'BRL', 'MXN', 'EUR'])
    }
})

Benefits:

• DRY principle maintained
• Single source of truth for URL state pattern
• Easier to add validation logic in one place
• Reduced maintenance burden

Minor Code Quality Issues

1. Unrelated change (line 58, RhinoDeposit.view.tsx): Type annotation added seems unrelated to URL state migration
2. Mixed concerns: AddMoneyBankDetails handles both flows with conditional logic - consider splitting

📋 Updated Recommendations (Prioritized)

HIGH Priority

1. Add amount validation to redirect guards - Prevents invalid amounts from bypassing validation
2. Extract shared URL state hook - Reduces duplication, improves maintainability

MEDIUM Priority

3. Add integration tests - Critical flows should have test coverage:

   • Happy path: input → KYC → details
   • Deep linking edge cases
   • Browser back/forward navigation
   • Amount validation bypass attempts

4. Consider migrating RequestFulfillmentFlow - For pattern consistency

5. Document the pattern - Add architecture decision record (ADR) explaining:

   • Why URL state over context
   • When to use each pattern
   • Migration guide for future flows

LOW Priority

6. Add error boundaries - Wrap add-money routes for graceful degradation
7. Remove unrelated changes - Clean up type annotation in RhinoDeposit.view.tsx
8. Consider splitting AddMoneyBankDetails - Separate add-money and request-fulfillment concerns

🎯 Summary

Aspect	Rating	Notes
Risk	🟡 MEDIUM	Critical issues fixed, remaining risks manageable
Performance	🟢 POSITIVE	Fewer re-renders, no latency impact
Code Quality	🟡 GOOD	Well-documented, type-safe, but DRY opportunities missed
Breaking Changes	🟢 LOW	OnrampFlowContext changes minimal, backwards compatible
Test Coverage	🔴 NONE	Critical gap - should add tests

Overall: This PR is in much better shape than the initial review. The critical deep-link validation issues are resolved, and the implementation is solid. The main concerns are:

1. DRY violations (duplication)
2. Lack of tests
3. Minor amount validation bypass

These are not blockers for merging but should be addressed in follow-up work.

Would you like me to:

1. Create issues for the follow-up items (tests, shared hook extraction, request fulfillment migration)?
2. Provide complete code for the shared hook extraction?
3. Draft integration test scenarios?

🌐 Web query:

What is nuqs library for Next.js and React? Is it production ready?

💡 Result:

Short answer

• Nuqs is a tiny (≈5–6KB gz) type-safe URL-search-params state manager for React/Next.js that exposes a useState-like API (useQueryState / useQueryStates), built-in parsers/serializers, history controls, adapters for multiple routers (Next.js app/pages, React SPA, Remix, React Router, TanStack Router), and server‑component helpers. [1][2][4]

Is it production ready?

• Yes — nuqs is actively maintained, version 2+ targets production frameworks (Next.js >=14.2, React 18.3/19, etc.), is tested against Next.js releases, has adapters and a testing adapter, and is used in production by multiple teams. That said, the maintainers note a Next.js-specific caveat around Next.js’s internal URLSearchParams context and are collaborating with Next.js to mitigate it; check the docs/release notes for adapter guidance and the latest compatibility notes before upgrading. [1][2][4][3]

Sources

• Official docs / features & adapters. [1][4]
• Installation / version compatibility (Next.js >=14.2, React versions). [2]
• Release/compatibility notes (InfoQ coverage mentioning Next.js caveat and ongoing fixes). [3]

---

@Hugo0, great question! Let me provide a comprehensive analysis of nuqs and the migration status.

📚 About nuqs Library

Based on my research, nuqs is production-ready and well-suited for this use case:

nuqs is a tiny (~5-6KB gzipped) type-safe URL-search-params state manager for React/Next.js that provides:

• useState-like API (useQueryState / useQueryStates)
• Built-in parsers/serializers (like parseAsString, parseAsStringEnum)
• History controls (push, replace, replaceIn)
• Adapters for multiple frameworks including Next.js App Router
• Active maintenance and tested against Next.js releases

Verdict on library choice: ✅ Excellent choice for URL-based state management in Next.js.

🔍 Migration Status: PARTIAL (Not Complete)

✅ What Now Uses nuqs (URL State)

Add-Money flows only:

1. Bank add-money flow (src/app/(mobile-ui)/add-money/[country]/bank/page.tsx)

   • Step management: inputAmount | kyc | collectUserDetails | showDetails
   • Amount tracking

2. Manteca regional method (src/components/AddMoney/components/MantecaAddMoney.tsx)

   • Step management: inputAmount | depositDetails
   • Amount tracking
   • Currency selection

3. AddMoneyBankDetails (reads URL state)

   • Reads amount from URL for display

❌ What Still Uses Context/useState (Old Patterns)

Multiple flows NOT migrated:

1. RequestFulfillmentFlowContext (src/context/RequestFulfillmentFlowContext.tsx)

   export enum RequestFulfillmentBankFlowStep {
       BankCountryList = 'bank-country-list',
       DepositBankDetails = 'deposit-bank-details',
       OnrampConfirmation = 'onramp-confirmation',
       CollectUserDetails = 'collect-user-details',
   }

   • Still uses enum-based step management
   • Still uses context for currentStep
   • This is the most problematic inconsistency since it's another onramp-related flow

2. OnrampFlowContext (partially reduced but still exists)

   • Removed: amountToOnramp, currentView
   • Still has: error, fromBankSelected, onrampData
   • Mixed pattern: URL state for steps/amount, context for transient data

3. Other Context-Based Flows:

   • WithdrawFlowContext - withdraw flow steps
   • ClaimBankFlowContext - claim flow steps
   • LinkSendFlowContext - link send flow steps
   • SetupFlowContext - setup wizard (currentStep with useState)
   • DirectSendFlowContext - direct payment flow
   • SemanticRequestFlowContext - semantic request flow
   • ContributePotFlowContext - contribute to pot flow

4. Component-Level useState:

   • MantecaFlowManager.tsx (claim flow): Uses useState<MercadoPagoStep>
   • Various other wizards/multi-step forms

⚖️ Inconsistency Assessment: MEDIUM-HIGH Concern

Current State Management Patterns in Codebase:

Pattern	Examples	Count	Benefits	Drawbacks
URL State (nuqs)	Add-money bank, Manteca	2 flows	Deep linking, bookmarking, browser nav	None in this context
Context + Enums	Request fulfillment, Withdraw, Claim	~5 flows	Familiar pattern	No deep linking, lost on refresh
Context + useState	Setup flow	1 flow	Simple	No persistence
Component useState	MantecaFlowManager (claim)	Multiple	Simplest	Most fragile

Specific Inconsistencies:

1. High Impact: Onramp Flows Split 🔴

• Add-money flow: Uses nuqs URL state ✅
• Request fulfillment flow: Uses context with enums ❌
• Problem: Two conceptually similar flows (both add money via bank) use completely different patterns
• User Experience: Request fulfillment users can't bookmark/share, add-money users can

2. Medium Impact: Developer Confusion 🟡

When working on flows, developers must decide:

• "Should I use URL state like add-money?"
• "Should I use context like request fulfillment?"
• "Should I use component state like MantecaFlowManager?"

No clear guidelines exist.

3. Medium Impact: Maintenance Burden 🟡

• Must maintain expertise in multiple patterns
• Harder to refactor/migrate features between flows
• Testing strategies differ between patterns

4. Low Impact: Mixed Context 🟢

OnrampFlowContext now has mixed responsibilities:

• URL state handles: step, amount (via nuqs)
• Context handles: error, fromBankSelected, onrampData
• This split is actually reasonable - transient/error state in context, flow state in URL

📋 Recommendations (Prioritized)

SHORT TERM (This PR)

✅ ACCEPT the partial migration as-is because:

1. The two migrated flows are complete and well-implemented
2. nuqs library is solid and production-ready
3. The migration reduces issues, doesn't introduce new ones
4. Perfect consistency can come later

MEDIUM TERM (Follow-up PRs)

Priority 1: Migrate Request Fulfillment Flow 🔴

// HIGH PRIORITY - Same domain as add-money
// src/context/RequestFulfillmentFlowContext.tsx
// Should use nuqs for step management like add-money does

• Most important for consistency since it's another onramp flow
• Users would benefit from deep linking here too
• Similar step patterns to add-money

Priority 2: Document the Pattern 🟡
Create an Architecture Decision Record (ADR):

# ADR: When to Use URL State vs Context

## Decision
- Multi-step flows with user input → URL state (nuqs)
- Transient app state (errors, loading) → Context
- Pure UI state (modal open/closed) → Component state

## Examples
- ✅ URL State: Onramp flows, withdrawal flows
- ✅ Context: Error handling, transient data
- ✅ Component State: Dropdown open/closed

Priority 3: Consider Other Flow Migrations 🟡
Evaluate if these benefit from URL state:

• Withdraw flow (probably yes)
• Claim flow (maybe - depends on UX goals)
• Setup flow (probably no - one-time wizard)

LONG TERM (Architecture)

Create a Standard Pattern:

// hooks/useFlowUrlState.ts
// Shared hook for all multi-step flows
export function useFlowUrlState<TStep>({ 
  steps, 
  defaultStep,
  additionalParams 
}) {
  // Centralized URL state management
  // Consistent validation
  // Standard redirect guards
}

🎯 Summary

Is this a complete migration?
❌ No - Only 2 out of ~10 multi-step flows use nuqs

Do we have inconsistent state management?
✅ Yes - But it's acceptable inconsistency because:

1. The migrated flows are well-contained (add-money)
2. No conflicts between patterns
3. Gradual migration is better than big-bang rewrite
4. nuqs is production-ready and appropriate

Should this block the PR?
❌ No - This PR improves the situation:

• Better UX for add-money flows
• Demonstrates the pattern for future migrations
• No breaking changes to other flows
• Clear path forward for consistency

Most Important Next Step:
Migrate RequestFulfillmentFlowContext to nuqs in a follow-up PR, since it's the most inconsistent pairing (both are onramp flows but use different patterns).

---

Would you like me to:

1. Create a follow-up issue for RequestFulfillmentFlow migration?
2. Draft an ADR template for state management patterns?
3. Create a shared useFlowUrlState hook for DRY?

Learnt from: Hugo0
URL: https://github.com/peanutprotocol/peanut-ui/pull/1602

Timestamp: 2026-01-02T13:14:32.616Z
Learning: In the peanut-ui codebase, the add-money flows (bank and Manteca) use nuqs library for URL-based state management (step, amount, currency via useQueryStates), while RequestFulfillmentFlowContext still uses enum-based context state. This creates intentional partial migration where URL state is used for user-facing flows that benefit from deep linking and bookmarking.
