@smithii/sdk

Framework-agnostic TypeScript SDK for automating Smithii's on-chain tools — call them from a server, a bot, a CLI, or any custom UI.

If you're looking for the no-code version, head to tools.smithii.io.

Let your Agent handle it

Paste this into Claude Code, Cursor, or any agent that supports the agent skills standard:

add smithii-sdk skill https://tools.smithii.io/skill/skill.md

Your agent will install the Smithii SDK skill and immediately know how to build pump.fun bundlers, anti-MEV bots, token creators, multisenders, and the rest of the toolset — without hallucinating method signatures or limits.

---

What you can build

• Pump.fun bundler bots — create a token and snipe it with up to 16 wallets atomically in the same block via Jito
• PumpSwap bundle buy / sell — multi-wallet trades on graduated pump.fun tokens
• Launchlab & Bonk (LetsBonk.fun) bundlers — Raydium LaunchLab token launch + snipe
• Moonit bundler — create and snipe on the Moonit protocol
• Anti-MEV volume bots — sandwichproof buy+sell bundles in the same block
• Token creator — deploy SPL tokens on Solana, EVM chains, and SUI
• Multisender — airdrop tokens to thousands of wallets in one transaction
• Token manager — revoke authorities, update metadata, snapshot holders
• Market maker — automated liquidity and volume management
• Vesting & claims — on-chain vesting schedules and claim flows
• Mantis — cross-chain bridging flows

Install

npm i @smithii/sdk

Install only the peer deps for the chain(s) you target:

# Solana
npm i @solana/web3.js @solana/spl-token @coral-xyz/anchor

# EVM
npm i viem

# SUI
npm i @mysten/sui

Quick start

Solana — Pump.fun bundler (create token + snipe with multiple wallets)

import { Connection, Keypair } from '@solana/web3.js'
import { PumpFunClient } from '@smithii/sdk/pump'

const client = new PumpFunClient({
  connection: new Connection(process.env.RPC_URL!),
  signer: yourSigner,
  jito: { uuid: process.env.JITO_UUID! },
  proxyUrl: process.env.PROXY_URL!,
})

const result = await client.createAndSnipeToken({
  name: 'My Token',
  symbol: 'MTK',
  description: 'My token description',
  image: imageFile,          // File or Blob
  devAmount: 0.5,            // SOL the dev wallet buys
  buyers: [
    { pk: 'base58-priv-key', amount: 0.1 },
    { pk: 'base58-priv-key', amount: 0.2 },
    // up to 16 wallets
  ],
})

console.log('Mint:', result.mint.toBase58())
console.log('Bundle IDs:', result.bundleIds)

Solana — Anti-MEV volume bot

import { AntiMEVClient } from '@smithii/sdk/anti-mev'

const client = new AntiMEVClient({
  connection,
  signer,
  backendUrl: process.env.BOTS_API_URL!,
})

// Sandwichproof buy+sell in same block
await client.runSingle({
  mint: 'TokenMintAddress',
  amount: 0.05,      // SOL per cycle
  cycles: 10,
  delayMs: 2000,
})

Solana — Bundle buy existing token (up to 25 wallets)

import { PumpFunClient } from '@smithii/sdk/pump'

await client.bundleBuy({
  mint: 'TokenMintAddress',
  buyers: [
    { pk: 'wallet-1-pk', amount: 0.1 },
    { pk: 'wallet-2-pk', amount: 0.15 },
  ],
})

EVM — Token creator + multisender

import { EvmTokenCreatorClient } from '@smithii/sdk/evm/token-creator'
import { EvmMultisenderClient } from '@smithii/sdk/evm/multisender'

const creator = new EvmTokenCreatorClient({ walletClient, chain: 'base' })
const { address } = await creator.deploy({ name: 'My Token', symbol: 'MTK', supply: 1_000_000n })

const sender = new EvmMultisenderClient({ walletClient, chain: 'base' })
await sender.send({ token: address, recipients: [{ address: '0x...', amount: 100n }] })

How it works

Every tool follows the same pattern:

1. Build — the SDK constructs the on-chain instructions (Jito bundles for Solana, calldata for EVM)
2. Pay — a small fee is charged via Smithii's on-chain payment program after the main tx confirms
3. Confirm — the SDK polls for confirmation and returns signatures / bundle IDs

All sensitive config (RPC URLs, private keys, Jito UUID) is passed via constructor — nothing is hardcoded.

Signers

Chain	Signer type
Solana	useWallet() from @solana/wallet-adapter-react, or a raw Keypair
EVM	viem.WalletClient or privateKeyToAccount
SUI	useWallet() from @suiet/wallet-kit
