How to Filter Jupiter Swap Events with Filtered gRPC

Jupiter is Solana's dominant swap aggregator — routing over 60% of all DEX volume. If you're building a trading bot, MEV strategy, or analytics dashboard, Jupiter swap data is essential. This guide shows how to receive pre-parsed Jupiter events in real-time using Subglow filtered gRPC.

Why Jupiter Data Is Different

Jupiter doesn't run a single AMM. It aggregates routes across Raydium, Orca, Meteora, Phoenix, and dozens of other venues. A single Jupiter swap might touch 3-4 different DEXs in one transaction. Parsing this manually means understanding every underlying program's instruction format — a massive engineering effort.

With Subglow's Jupiter filter, we handle the route parsing. You receive a clean JSON object with the input token, output token, amounts, route path, and price impact — regardless of which underlying DEXs were used.

Supported Jupiter Events

Event	Description	Key Fields
swap	Instant swap via aggregated route	in_token, out_token, in_amount, out_amount, route, price_impact
limit_order	Limit order placed or filled	in_token, out_token, limit_price, status, expiry
dca	DCA execution triggered	in_token, out_token, amount, interval, executions_remaining

Node.js: Jupiter Swap Monitor

This example tracks large Jupiter swaps (over $1,000 equivalent) in real-time. Use this as the foundation for whale-watching bots, copy-trading systems, or volume analytics.

const client = new Subglow({
  url: "grpc.subglow.io:443",
  apiKey: process.env.SUBGLOW_KEY,
  filter: ["jupiter"],
});

client.subscribe((tx) => {
  if (tx.type === "swap" && tx.parsed.out_amount_usd > 1000) {
    console.log(`Whale swap: ${tx.parsed.in_token} → ${tx.parsed.out_token}`);
    console.log(`  Amount: $${tx.parsed.out_amount_usd.toFixed(2)}`);
    console.log(`  Route: ${tx.parsed.route.join(" → ")}`);
    console.log(`  Price impact: ${tx.parsed.price_impact.toFixed(3)}%`);
  }
});

DCA & Limit Order Tracking

Jupiter's DCA and limit orders create recurring on-chain activity. Track limit_order events to see when large orders fill — these often indicate smart money accumulation patterns. DCA executions show steady buying pressure on specific tokens.

Building a Volume Dashboard

Aggregate Jupiter swap events to build real-time volume dashboards by token pair. Since Subglow delivers pre-parsed data with USD amounts, you can skip the price-fetching step and build your aggregations directly from the stream.
