A modern TypeScript SDK for the LetsBonk trading protocol on Solana.

• 🔥 Buy/Sell tokens with slippage protection
• 🚀 Launch new tokens with metadata
• 🏊 Pool management and state queries
• 🛡️ Type-safe with full TypeScript support
• ⚡ High performance with structured logging
• 🔧 Modular architecture for optimal bundle size

npm install letsbonkdotfun-sdk

import { Connection, Keypair } from '@solana/web3.js';
import { createSDK } from 'letsbonkdotfun-sdk';

const connection = new Connection('https://api.mainnet-beta.solana.com');
const sdk = createSDK(connection);

// Buy tokens
const buyer = Keypair.fromSecretKey(/* your private key */);
const result = await sdk.buy(
  buyer,
  mintAddress,
  BigInt(1000000), // amount in lamports
  BigInt(0) // minimum tokens out
);

if (result.success) {
  console.log('Buy successful:', result.data.signature);
}

• sdk.buy(buyer, mint, amountIn, minimumOut) - Buy tokens
• sdk.sell(seller, mint, amountIn, minimumOut) - Sell tokens
• sdk.initialize(payer, creator, mint, metadata) - Create new token pool
• sdk.initializeAndBuy(...) - Launch token and buy in one transaction

• sdk.accounts - Account management and queries
• sdk.transactions - Transaction building and execution
• sdk.pools - Pool state and operations
• sdk.metadata - Token metadata handling

const sdk = createSDK(connection, {
  commitment: 'confirmed',
  skipPreflight: true,
  logging: { level: 'info' }
});
