This guide provides instructions on how to get started with building on Meteora’s DLMM program using the DLMM TypeScript SDK. Before you begin, here are some important resources:

Typescript SDK

Meteora DLMM Typescript SDK

DLMM NPM Package

Meteora DLMM NPM Package

​
Installation

To use the SDK in your project, install it using your preferred package manager:
  • npm
  • pnpm
  • yarn
npm install @meteora-ag/dlmm @solana/web3.js

​
Initialization

Once installed, you can initialize the DLMM client in your Node.js project like this: 
import DLMM from '@meteora-ag/dlmm'
import { Connection, PublicKey } from '@solana/web3.js';

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

// Create pool instances

// e.g. creating a DLMM pool
// You can get your desired pool address from the API https://dlmm-api.meteora.ag/pair/all
const USDC_USDT_POOL_ADDRESS = new PublicKey('ARwi1S4DaiTG5DX7S4M4ZsrXqpMD1MrTmbu9ue2tpmEq')
const dlmmPool = await DLMM.create(connection, USDC_USDT_POOL_ADDRESS);

// e.g. creating multiple pools
const dlmmMultiplePools = await DLMM.createMultiple(connection, [USDC_USDT_POOL_ADDRESS, ...otherPoolAddresses]);

​
Testing the SDK (for contributors)

If you have cloned the SDK repository and want to run the built-in tests: 
# Install dependencies
cd ts-client
bun install

# Run tests
bun test
