Stream
on-chain activity
in real time.

A single WebSocket connection. Pre-parsed transfers, swaps and exchange events streamed from every Pinax-supported chain — ready to render the moment they confirm.

msgs = billable WebSocket frames · events = trades / transfers unpacked from each frame. Typically one message per block per table — many events inside.

Why WebSockets

Push, don’t poll.

RPC polling burns requests, capacity and your roadmap. Open one socket, subscribe to what you care about, and let Pinax push fresh data the instant a block lands.

Sub-second push
<200ms P95 from on-chain finality to your client. Transfers, swaps and exchange events arrive the moment they’re confirmed.
Persistent connection
One socket, many subscriptions. Multiplex blocks, transfers and swaps over a single TLS-encrypted connection — no reconnect storm, automatic resume on drop.
Skip the polling tax
Stop spamming eth_getBlockByNumber. One subscription replaces hundreds of throwaway requests and dramatically lowers your egress bill.

Available streams

Pre-parsed streams,
one socket.

Live today: DEX swaps and token transfers across Solana and 8 EVM chains. Each subscription is independently billed only for messages it actually pushes — more stream types coming.

Solana DEX Swaps
Normalized DEX swaps across Raydium, Orca, Meteora, Pump.fun and more — pre-parsed per trade.

Quickstart

Connect in three lines.

Bring your own client — any standard WebSocket library works. Authenticate with your Pinax API key, send one JSON-RPC subscription, and read messages off the socket.

import WebSocket from "ws";

// Subscribe via path: wss://<host>/ws/<chain>@<topic>?token=<API_KEY>
const ws = new WebSocket(
  `wss://ws.pinax.network/ws/solana@swaps?token=${process.env.PINAX_KEY}`
);

ws.on("open", () => console.log("connected"));

ws.on("message", (msg) => {
  const event = JSON.parse(msg.toString());
  console.log("swap →", event);
});
vs. RPC Polling

A better way
to read chains.

For anything resembling real-time, polling is a tax. Here’s what changes when you move to WebSockets.

Pinax WebSockets
RPC polling
Event latency
● <200ms after confirmation
2–12s, bounded by your polling interval
Pre-parsed events
● Transfers, swaps, perps decoded server-side
○ Raw logs only — decode & normalize yourself
Server-side filtering
● Filter by address & topic at the edge
Client-side after fetching full blocks
Connection overhead
● One TLS connection, multiplexed
A request & response per poll
Reconnect & resume
● Automatic resume from last seen block
Manual cursor management

Live UIs, alerts, trading bots, indexers
Batch reads, historical queries
Pricing

Pay per message.
Nothing else.

No connection fees. No idle charges. No per-chain markup. You pay only for messages we actually deliver to your socket.

Usage-based · Beta pricing
$0.50
per 10K messages.

$0.00005 per message, billed alongside your other Pinax usage. Beta accounts get a generous free tier while we tune the service.

  • Billed per message, not per event.
  • Heartbeats and protocol frames are free.
  • Same API key as RPC, Firehose, Token API.
