From aa7ccfeae4d778ab62decbd58c3ddb3f74268274 Mon Sep 17 00:00:00 2001 From: Adam Soltys Date: Sat, 27 Jun 2026 09:43:07 -0700 Subject: Use Fulcrum (Electrum/WS) for regtest data + push, dropping esplora Regtest now talks to a local Fulcrum over its native Electrum WebSocket for both chain data and realtime push, instead of esplora REST + a separate watcher. This matches prod (Fulcrum) and gives ~2-3x lower latency than the previous electrs polling. getBackend()/electrumCandidates() route regtest to the Electrum backend at the configured Fulcrum WS (default ws://localhost:50003); the wallet's realtime path is ungated for regtest. ElectrumApi already covers every call (utxos, history, fees, broadcast), incl. the swap feature.
