This guide shows how to install and initialize the official DLMM TypeScript SDK, @meteora-ag/dlmm. Before you begin, here are some important resources:

DLMM NPM Package

Meteora DLMM NPM Package

​
Installation

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

​
Initialization

Once installed, initialize a pool client with a Solana connection and a DLMM pool address: 
import DLMM from "@meteora-ag/dlmm";
import { Connection, PublicKey } from "@solana/web3.js";
import BN from "bn.js";

const connection = new Connection(process.env.RPC_URL!, "confirmed");

const poolAddress = new PublicKey("ARwi1S4DaiTG5DX7S4M4ZsrXqpMD1MrTmbu9ue2tpmEq");
const dlmmPool = await DLMM.create(connection, poolAddress, {
  cluster: "mainnet-beta",
});
You can find pool addresses with the Data API: 
curl "https://dlmm.datapi.meteora.ag/pools?page=1&page_size=20"
To initialize several pools efficiently: 
const pools = await DLMM.createMultiple(connection, [
  poolAddress,
  ...otherPoolAddresses,
]);

​
Cluster And Program ID

The SDK defaults to the public DLMM program ID: 
LBUZKhRxPF3XUpBCjp4YzTKgLccjZhTSDM9YuVaPwxo
Pass opt when using devnet or a custom program ID: 
const dlmmPool = await DLMM.create(connection, poolAddress, {
  cluster: "devnet",
})

​
Testing The SDK

If you have cloned the SDK repository, start with package-level checks: 
cd ts-client
pnpm install
pnpm run build
pnpm run unit-test
