Program Data Streams

Real-time Solana program data streams

Introduction

Program Data Streams are a high-performance gRPC endpoints that provides real-time, parsed Solana blockchain data streams by program. It solves the critical challenge of efficiently monitoring and reacting to on-chain activities by delivering pre-parsed account states and transaction instructions for specific Solana programs.

Powered by the Yellowstone Vixen open-source framework which provides the building blocks to create custom indexes for specific programs, accounts, and transactions. Vixen Streams enables developers to build responsive applications that can react to on-chain events without the complexity of building and maintaining custom parsing infrastructure.

The Problem

Traditionally, monitoring blockchain activity requires:

• Polling RPC endpoints, which is inefficient and prone to missing fast-moving events.

• Custom parsing and filtering logic, which is complex to develop and difficult to scale.

• High infrastructure costs, as developers must manage large volumes of raw blockchain data.

The Solution

Vixen Streams addresses these pain points by providing:

• gRPC Streaming – Real-time, high-performance delivery of parsed Solana blockchain data.

• Multi-Program Support – Detailed parsing for multiple Solana programs, with more coming soon.

• Scalability – Designed to handle high transaction volumes efficiently.

• TypeScript SDK – A simple and secure SDK for TypeScript applications with token-based authentication, abstracting away gRPC and protobuf complexity.

Getting Started

Install the Typescript SDK

npm install @triton-one/vixen-stream

Usage

import {
  ProgramStreamsServiceClient,
  ProgramUpdateType,
  credentials,
  createCallCredentials,
  ProgramAddress,
} from "@triton-one/vixen-stream";

const creds = credentials.createSsl();

// <token> is your Triton One authentication token
const callCredentials = createCallCredentials("<token>");

const combinedCredentials = credentials.combineChannelCredentials(
  creds,
  callCredentials
);

// <endpoint> is your Triton One RPC endpoint
const client = new ProgramStreamsServiceClient(
  "<endpoint>",
  combinedCredentials
);

// Subscribe to account and instruction updates for the token keg program
let stream = client.Subscribe({
  program: ProgramAddress.Token,
});

// Handle the update events as you see fit. Write them to a database, call an API, or submit a Solana transaction.
stream.on("data", function (update: ProgramUpdateType<ProgramAddress.Token>) {
  console.log(update);
});

stream.on("end", () => console.log("end"));
stream.on("error", (e: Error) => console.log("error: ", e));

FAQ

❓ What commitment level are streams set to?

Answer: Streams deliver change events for all commitment levels (Processed, Confirmed, and Finalized).

❓ I’m getting a parser error. What should I do?

Answer: Make sure you have the latest SDK version installed. Check npm for the most recent release.

❓ Are streams globally distributed?

Answer: Yes. Our infrastructure runs in the USA, EU, and AP regions, minimizing latency for developers worldwide. ❓ Can I stream multiple programs simultaneously?

Answer: Yes. You can open multiple subscriptions to stream data for different programs in parallel.

❓ How do I authenticate?

Answer: Authentication is handled via token-based credentials. You must provide a valid Triton One token when initializing the client. Since we are currently in Beta, you’ll need to contact Triton Support to receive a token.

❓ What’s the difference between this and RPC polling?

Answer: RPC polling requires repeatedly fetching data and parsing it manually, which is slower and resource-intensive. Vixen Streams pushes pre-parsed, program-specific updates in real time, reducing overhead and improving responsiveness.

❓ Is there rate limiting?

Answer: No, there is no rate limiting. However, usage is billed based on bandwidth consumption.
