subscribe_migrations - migrations

Live feed of pool migration events on the DEXes you pick (today: PumpFun bonding-curve → PumpSwap AMM). Server emits migration. Pass protocols (today only PUMPFUN emits migration events).

Channel	Socket.IO event
Auth	auth.api_key in the handshake
Emits	migration

Example

JavaScript

Click an icon to toggle it. The example regenerates live, so you can paste it straight into your client.

socket.on("migration", (m) => {
  console.log(`${m.mint} migrated ${m.old_pool} → ${m.new_pool}`);
});

socket.emit("subscribe_migrations", {
  protocols: ["PUMPFUN"],
});

Python

import socketio

sio = socketio.Client()

@sio.on("migration")
def on_migration(m):
    print(f"{m['mint']} migrated {m['old_pool']} → {m['new_pool']}")

sio.connect("https://api.pumpdata.fun", auth={"api_key": "pd_xxxxxxxx…"})
sio.emit("subscribe_migrations", {"protocols": ["PUMPFUN"]})
sio.wait()

# later, to stop (free):
# sio.emit("unsubscribe_migrations", {"protocols": ["PUMPFUN"]})

Response - migration

  "protocol":  "PUMPFUN",
  "mint":      "Gc6r…pump",
  "old_pool":  "<bonding curve>",
  "new_pool":  "<pumpswap pool>",
  "tx":        "<signature>",
  "time":      1779812627

Notes

• After a migration the old pool is marked active: false in /metadata; subsequent lookups by mint resolve to the new pool automatically.
• Combine with subscribe_new_tokens for the launch side, and subscribe_trades on the new pool for the first trades.
