Stream Pump AMM Data with Helius - Standard WebSocket
Learn how to stream live Pump AMM data from Solana using the Standard WebSocket with Helius.
Standard WebSocket
Why choose Standard WebSocket – simple integration, available
on all plans. Uses Solana PubSub logsSubscribe
, so you receive
log messages only.
Available on all Helius plans, including Starter and Growth plans.
How it works – connect to the standard WebSocket endpoint, subscribe to logs mentioning the Pump AMM program, and process the incoming log data. The sample includes automatic reconnection with exponential backoff.
Requirements
- Node.js ≥ 18 (tested with v20)
- TypeScript ≥ 5 if you plan to run the
.ts
samples withts‑node
- Any Helius plan – works with all plan tiers
- An environment variable named
HELIUS_API_KEY
that stores your API key
Install dependencies globally: npm i -g typescript ts‑node
Implementation
Install Dependencies
Create the WebSocket Client

with the following code:
Set Environment Variables
Add your Helius API key as an environment variable:
Replace your-helius-api-key
with your actual Helius API key from the dashboard.
Run the Application
Execute the script to start streaming Pump AMM data:
You will receive log messages that mention the Pump AMM program. To fetch the full transaction, call getTransaction
with the signature from the log entry.
Key benefits
- Universal access - Available on all Helius plans, including free tier
- Lightweight - Minimal data transfer since only logs are streamed, not full transactions
- Easy to implement - Uses standard Solana RPC WebSocket protocol
- Low barrier to entry - Perfect for prototyping and initial monitoring
Getting full transaction details
Since the Standard WebSocket only provides log messages, you’ll need an additional step to get complete transaction data:
