Solana Raydium Launchlab Account Parsing

Real-Time Raydium Launchlab Account Streaming via Solana's Yellowstone gRPC (geyser)

Beyond just tracking transactions, understanding the live, evolving state of Raydium Launchpad accounts is crucial for monitoring new project initiations. These accounts hold vital, real-time details pertaining to the bonding curve's progress, current fundraising status, and the eventual transition of tokens to a new liquidity pool. This document will guide you through streaming and parsing real-time account data for Raydium Launchpad, providing immediate insights into the entire lifecycle from token launch to pool establishment.

The complete source code for this project is available on GitHub.

• TypeScript

• Rust

Please feel free to clone the repository and try it out. Additionally, you will find other relevant and useful code examples related to gRPC and streaming here.

Step-by-Step Breakdown

This project consists of two key components:

1. Streaming Raydium Launchpad Accounts via Yellowstone gRPC

2. Decoding those accounts using the program's IDL

Streaming Accounts Using gRPC

The first step involves initializing the Solana Yellowstone Client. You can get Solana Yellowstone gRPC access from the Shyft Dashboard. Please check out our gRPC Authentication Docs for more details.

Initializing the Client

Once you have the authentication details, you can initialize the client in the following manner,

TypeScript

import Client from "@triton-one/yellowstone-grpc";

const client = new Client(
  "YOUR-GRPC-ENDPOINT", //yellowstone grpc url
  "GRPC-ACCESS-TOKEN", //authentication token
  undefined
);

Rust

You can use any Yellowstone gRPC endpoint with this client. An access token is optional, as some gRPC services don't require authentication.

The Rust client supports several additional options, as demonstrated in the example above. Most of these options are also available for the TS client, where they are passed as the third argument to the Client constructor.

Specifying what data to stream from gRPC

To specify what on-chain data, we send a SubscribeRequest over the existing Solana Yellowstone gRPC client. These Request allows you to filter for specific accounts, transactions, slots, or other Solana on-chain events, giving you full control over the data you receive.

SubscribeRequests use filters to determine what type of on-chain data to stream. When streaming account-level data, the account filter plays a crucial role. Specifically, the owner field within the filter allows you to stream data for accounts owned by a particular Solana program.

TypeScript

const req: SubscribeRequest = {
  "slots": {},
  "accounts": {
    "pumpfun": {
      "account": [],
      "filters": [],
      "owner": ["LanMV9sAd7wArD4vJFi2qDdfnVhFxYSUg6eADduJ3uj"] // This field indicates 
    }
  },
  "transactions": {},
  "blocks": {},
  "blocksMeta": {},
  "accountsDataSlice": [],
  "commitment": CommitmentLevel.PROCESSED, // Subscribe to processed blocks for the fastest updates
  "entry": {},
  "transactionsStatus": {}
}

Rust

Once established, the stream will begin sending data directly to your application. You have the flexibility to modify your subscription on the fly, allowing you to change the data specifications you receive without stopping your stream. For more details on reconnecting and re-starting the stream from a specific slot, or closing your gRPC connection, you can find additional information in our documentation.

Decoding the received accounts

When account data updates on-chain, it's immediately sent over the stream. To make sense of this raw information, we need to decode it. In JavaScript/TypeScript, we typically use BorshAccountCoder from @coral-xyz/anchor to parse the account data like this.

On Rust however, we can use the Solores generated IDL like in our transaction parsing example.

TypeScript

import { BorshAccountsCoder } from "@coral-xyz/anchor";

const program_idl = JSON.parse(fs.readFileSync('./idls/raydium_launchpad.json', "utf8"));

const coder = new BorshAccountsCoder(program_idl); //initializing BorshCoder with IDL

export async function decodeRaydiumLaunchpadTxnData(data) {
    if (!data || !data.account || !data.account.account) return;

    const dataTx = data.account.account;

    let parsedAccount;
    try {
        parsedAccount = coder.decodeAny(dataTx?.data); //decoding account
    } catch (error) {
        console.error("Failed to decode pool state:", error);
    }
}
