v0.2.3

v0.2.3
Restore reliability

• Fix: importing a wallet that had been previously migrated to BIP-44 keys now succeeds. Some users were getting a "key mismatch" error during restore; this is fully resolved.
• Fix: 401 errors on first load after restoring a wallet are gone (registration now completes before the popup queries authenticated endpoints).
• Self-healing: the extension now silently re-syncs keys with the backend on unlock if they ever drift, so this class of issue can't recur.
• No changes to your seed phrase, addresses, or local storage. Existing wallets continue to work without action.

v0.2.2 — Cake Wallet + Grin wallet compatible derivation

What's new

Fixes key derivation to be compatible with Cake Wallet (XMR/WOW) and grin-wallet/Grim (Grin). All existing v1 and v2 wallets are migrated to v3 via auto-sweep.

Key derivation (v3)

• XMR/WOW: BIP32 secp256k1 at m/44'/128'/0'/0/0 — same as Cake Wallet. Your 12-word mnemonic now works in both Smirk and Cake Wallet.
• Grin: useBip39=false (raw entropy HMAC) — same as grin-wallet/Grim. Your slatepack address now matches.
• BTC/LTC: Unchanged (already standard BIP44).

Migration

• v1 (legacy SHA256) and v2 (buggy 3-level SLIP-10) wallets auto-sweep to v3 on upgrade
• Grin migration does a cross-wallet SRS sweep (old keys → new keys)
• Post-migration sync notice explains balances may show zero for 5-10 minutes
• In-memory keys updated to v3 before LWS re-registration (fixes stale view key bug)

Balance display

• Grin: outputs with 1-9 confirmations now show as "locked" instead of "pending"
• "pending" is reserved for 0-confirmation transactions

v0.2.1

What's New

Standard Key Derivation (BIP44/SLIP-10)

XMR and WOW keys now use industry-standard BIP44/SLIP-10 derivation with Keccak-256 view keys — the same standard used by Cake Wallet. Your 12-word recovery phrase is now portable to other compatible wallets.

GRIN keys aligned with grin-wallet/Grim standard path.

BTC, LTC, and your recovery phrase are unchanged.

Automatic Migration

When you open Smirk, a banner prompts you to upgrade. The extension automatically sweeps funds from old addresses to new ones for all assets (XMR, WOW, and GRIN) — no manual action beyond clicking "Upgrade." Wallet auto-locks after completion for a clean restart.

Privacy: Disable window.smirk Detection

New toggle in Settings > Security: "Disable window.smirk on websites." When enabled, websites cannot detect that Smirk is installed, preventing browser fingerprinting. Disables dApp integration when active.

Security Improvements

• PBKDF2 auto-upgrade from 100K to 600K iterations on first unlock
• BIP-137 Bitcoin signature format (Base64, was hex)
• RFC 8032 Ed25519 signatures (raw message, was SHA256 pre-hash)
• Content script origin restricted to smirk.cash
• dApp connect scoped per-asset

Backend

• Accepts both old and new signature formats during transition (until July 2026)
• Migration endpoint for key updates
• Backend API now at https://backend.smirk.cash (DNS-based, no hardcoded IP)

Install

• Chrome/Brave/Edge: Upload smirk-wallet-chrome-v0.2.1.zip via chrome://extensions (Developer mode), or install from Chrome Web Store once approved
• Firefox: Upload smirk-wallet-firefox-v0.2.1.zip via about:debugging
• Source code included for Firefox review: smirk-wallet-source-v0.2.1.zip

v0.1.9

v0.1.9

Grin

• Invoice flow fix — fixed Identifier constructor bug that caused all change outputs to derive at nChild=0, breaking verifyKernelSums on finalization
• Balance accuracy — balance now calculated from actual UTXOs instead of transaction history, preventing phantom balance from untracked outputs
• Locked/pending display — balance now shows confirmed, locked (1-9 confirmations), and pending amounts separately
• Auto-copy slatepacks — all Grin flows (send, receive, invoice) now auto-copy slatepacks to clipboard
• Human-readable errors — insufficient balance errors now show GRIN amounts instead of nanogrin
• UX — return to main wallet view after completing a receive

XMR/WOW

• Pending detection for internal sends — smirk-to-smirk transfers now show "+X.XX pending" instantly on the receiver
• Wallet address re-registration — addresses always re-register with LWS on unlock, preventing stale webhook issues

General

• Added retry logic to output and relay API calls
• Service worker import fixes and social tip UX improvements

v0.1.8

Fix bug in payment request popup
