buildSubscribeMessage

Build the subscribe frame to send on (re)connect for a notifications endpoint.

For enigma, this is a channel_patterns frame scoped to the account with wildcard identifiers (every quote id for the account). The frame is returned as a JSON string, ready to send.

The rasa protocol has its own builder, buildRasaSubscribeMessage(addresses): one socket carries many SubAccounts, so its frame is just the full address list — { "address": ["0x…", …] }. watchNotifications manages that list for you; reach for the builder only when driving a raw socket yourself.

import { buildRasaSubscribeMessage, buildSubscribeMessage } from "@symmio/trading-core";
 
const frame = buildSubscribeMessage({
  account: "0xaccount...",
  channel: "Hyper-EVM_Solver-Low-Cap_Production",
  protocol: "enigma",
});
 
const rasaFrame = buildRasaSubscribeMessage(["0xaccount..."]);
// '{"address":["0xaccount..."]}'

Parameters

The single argument is a BuildSubscribeMessageParameters object:
