Raydium Pool Keys Fetcher

A TypeScript utility for fetching Raydium pool keys for a given token address on the Solana blockchain. This package allows you to get market IDs and liquidity pool keys using the Raydium SDK and Solana web3.js. Important: You need an RPC that has the RPC call "getProgramAccounts" enabled. This will not work with the public mainnet-beta rpc, but will work fine free tier RPC's from Helius for example.

Installation

npm install raydium-pool-keys

Usage

Importing the Package

import { Connection, PublicKey } from '@solana/web3.js';
import { getMarketIdForTokenAddress, getPoolKeysForTokenAddress } from 'raydium-pool-keys';

Fetching Market ID for a Token Address

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

getMarketIdForTokenAddress(connection, tokenAddress)
  .then((marketId) => {
    if (marketId) {
      console.log('Market ID:', marketId.toString());
    } else {
      console.log('Market ID not found for the provided token address.');
    }
  })
  .catch((error) => {
    console.error('Error fetching Market ID:', error);
  });

Fetching Pool Keys for a Token Address

getPoolKeysForTokenAddress(connection, tokenAddress)
  .then((poolKeys) => {
    if (poolKeys) {
      console.log('Pool Keys:', poolKeys);
    } else {
      console.log('Pool Keys not found for the provided token address.');
    }
  })
  .catch((error) => {
    console.error('Error fetching Pool Keys:', error);
  });

API

getMarketIdForTokenAddress(connection: Connection, tokenaddress: string): Promise<PublicKey | null>

Fetches the market ID for a given token address.

• connection: An instance of Connection from @solana/web3.js.
• tokenaddress: The token address for which to fetch the market ID.

Returns a Promise that resolves to a PublicKey if found, otherwise null.

getPoolKeysForTokenAddress(connection: Connection, tokenaddress: string): Promise<LiquidityPoolKeys | null>

Fetches the liquidity pool keys for a given token address.

• connection: An instance of Connection from @solana/web3.js.
• tokenaddress: The token address for which to fetch the pool keys.

Returns a Promise that resolves to LiquidityPoolKeys if found, otherwise null.

Constants

You can define constants in a separate file (e.g., constants.ts) and import them as needed. Here's an example of what your constants.ts might look like:

export const RAYDIUM_LIQUIDITY_POOL_V4_ADDRESS = 'YourRaydiumLiquidityPoolV4AddressHere';
export const WSOL_ADDRESS = 'YourWrappedSOLAddressHere';

Example constants.ts

export const RAYDIUM_LIQUIDITY_POOL_V4_ADDRESS = 'RAYDIUM_LIQUIDITY_POOL_V4_ADDRESS_HERE';
export const WSOL_ADDRESS = 'So11111111111111111111111111111111111111112';
