WebSocket

The WebSocket API streams real-time Solana DEX transactions directly to your application. Get instant notifications for token launches, swaps, migrations, and liquidity events—filtered exactly how you need them.

Why Use WebSocket?

• Real-time data: Stream directly from Solana blockchain nodes
• Server-side filtering: Only receive transactions matching your criteria
• Flexible filters: Track multiple tokens, wallets, or event types at once

Platforms Supported

Platform	Events
Pump Fun	Token launches, trades, migrations
Pump Swap	Pool creation, trades, liquidity deposits/withdrawals

Filter Logic

Filters use array fields with simple logic:

• AND between fields — must match all specified fields
• OR within arrays — matches any value in the array

{
  "platform": ["pump_fun", "pump_swap"],
  "eventType": ["trade"],
  "mint": ["TokenA...", "TokenB..."]
}

This matches: trades on either platform involving TokenA or TokenB.
