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](https://github.com/rpcpool/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](https://www.npmjs.com/package/@triton-one/vixen-stream) ```bash npm install @triton-one/vixen-stream ``` ### Usage ```typescript import { ProgramStreamsServiceClient, ProgramUpdateType, credentials, createCallCredentials, ProgramAddress, } from "@triton-one/vixen-stream"; const creds = credentials.createSsl(); // is your Triton One authentication token const callCredentials = createCallCredentials(""); const combinedCredentials = credentials.combineChannelCredentials( creds, callCredentials ); // is your Triton One RPC endpoint const client = new ProgramStreamsServiceClient( "", 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) { console.log(update); }); stream.on("end", () => console.log("end")); stream.on("error", (e: Error) => console.log("error: ", e)); ``` ## Supported Programs The following table lists the supported programs and their corresponding addresses.

### 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](https://www.npmjs.com/package/@triton-one/vixen-stream) 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. --- # Agent Instructions This documentation is published with GitBook.
