Streaming Real-Time Solana Transactions with Solana Tracker gRPC

Solana's lightning-fast blockchain demands real-time data solutions. Enter gRPC streaming with Solana Tracker - a powerful way to tap into the pulse of Solana transactions as they happen. This guide will walk you through setting up a gRPC stream for live Solana transaction data.

Why gRPC Streaming?

Real-Time Updates: Get transaction data the instant it hits the blockchain.
Efficient Filtering: Receive only the data relevant to your application.
High Performance: gRPC's lightweight protocol ensures speedy data transfer.

Prerequisites

Before we dive in, make sure you have:

A Solana Tracker shared gRPC or a dedicated node Available here
A server-side backend (we'll use Node.js in this example)

Setting Up the Stream

1. Initialize the gRPC Client

First, install the Yellowstone gRPC client from Triton:

npm install @triton-one/yellowstone-grpc

Then, set up your client:

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

const client = new Client(
  "https://grpc.solanatracker.io", // Your Solana Tracker gRPC URL
  "key-here",
  undefined
);

Create a subscription request to filter the transaction stream:

const req = {
  accounts: {},
  slots: {},
  transactions: {
    pump: {
      vote: false,
      failed: false,
      signature: undefined,
      accountInclude: ['6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P'], // Pumpfun Address
      accountExclude: [],
      accountRequired: [],
    },
  },
  transactionsStatus: {},
  entry: {},
  blocks: {},
  blocksMeta: {},
  accountsDataSlice: [],
  ping: undefined,
  commitment: CommitmentLevel.CONFIRMED, // Receive Confirmed Transactions
};

const stream = await client.subscribe();

3. Process the Stream

Handle incoming transaction data:

stream.on("data", (data) => {
  if (data?.transaction) {;
    // Process transaction data here
  }
});

Handling Disconnects

Implement a reconnection mechanism for reliability:

async function maintainSubscription(client, request) {
  while (true) {
    try {
      await handleStream(client, request);
    } catch (error) {
      console.error("Stream error, reconnecting in 1s...", error);
      await new Promise(resolve => setTimeout(resolve, 1000));
    }
  }
}

Conclusion

With Solana Trackers's Yellowstone gRPC service, you now have a powerful tool to stream and process Solana transactions in real-time. This opens up possibilities for building responsive DApps, trading bots, and analytics platforms that can react instantly to on-chain events.
