Package Overview

The DLMM TypeScript SDK provides a comprehensive toolkit for building applications with concentrated liquidity on Solana. This SDK enables developers to create high-performance trading interfaces, liquidity management systems, and DeFi applications that leverage dynamic liquidity market maker (DLMM) mechanics.

Installation

Required Dependencies: The DLMM SDK requires Solana Web3.js for blockchain interactions. Both packages are essential for basic functionality.
# Core DLMM SDK for concentrated liquidity operations
npm install @saros-finance/dlmm-sdk

# Solana Web3.js for blockchain connection and transaction handling
npm install @solana/web3.js

​
Quick Start Example

import { LiquidityBookServices, MODE } from '@saros-finance/dlmm-sdk';
import { PublicKey } from '@solana/web3.js';

// Initialize SDK with config object (not Connection)
const dlmmService = new LiquidityBookServices({
  mode: MODE.MAINNET, // or MODE.DEVNET for testing
  options: {
    rpcUrl: "https://api.mainnet-beta.solana.com" // or devnet URL
  }
});

// Read DLMM program ID from the SDK at runtime (no hardcoding)
const programId = dlmmService.getDexProgramId();
console.log('DLMM programId:', programId.toString());

// First fetch pool metadata
const poolAddress = "9P3N4QxjMumpTNNdvaNNskXu2t7VHMMXtePQB72kkSAk";
const metadata = await dlmmService.fetchPoolMetadata(poolAddress);

// Get swap quote using the quote method with metadata
const quoteResult = await dlmmService.quote({
  amount: 1_000_000, // 1 USDC (6 decimals)
  metadata,
  optional: { 
    isExactInput: true, 
    swapForY: true, 
    slippage: 0.5 
  }
});

console.log(`Output: ${quoteResult.amountOut} tokens`);
