Realtime via self-hosted ZMQ watcher (Electrum-over-WS)
Replace the unreliable public WebSocket push (mempool/blockchain.info address
subscriptions never reliably fire) with a private notification service:
- tools/zmq-watcher.js: a standalone Bun service (reusing coinos lib/zmq.ts's
ZMTP subscriber) that reads Bitcoin Core's ZMQ rawtx/rawblock, computes the
scripthash of each output, and pushes a blockchain.scripthash.subscribe
notification to subscribed clients. No historical index (~24MB RAM) — just the
live tx stream. Runs on the coinos box reading its Core's ZMQ.
- wallet.js: realtime client now speaks the Electrum protocol (server.version,
scripthash.subscribe, server.ping) over the WS; any scripthash notification
triggers the existing refreshLive() (REST stays the source of truth).
- api.js: wsUrl -> wss://coinos.io/electrum.
Verified end-to-end: live mempool txs to subscribed addresses notify instantly.
