# Fulcrum for regtest — an Electrum server over WebSocket, matching what prod
# runs. Replaces the old electrs + ews bridge for Hal's realtime: it gets instant
# block/mempool pushes from bitcoind's ZMQ (see sampledata/bitcoin/bitcoin.conf
# zmqpubhashblock/hashtx) and serves them to the browser over the WS port.
# Config + datadir live under the gitignored data/ (seeded from sampledata by
# setup.sh). Start after the main stack (needs `bc`):
#   docker compose -f compose.fulcrum.yml up -d
