We implement, you ship. Async, documented, done in days.
Why Fulcrum
Fulcrum's C++ implementation typically completes initial indexing 30-50% faster than Electrs Rust on the same hardware. Steady-state throughput is also higher. Trade-off: somewhat higher memory usage.
Hardware Sizing
Fulcrum is happiest with NVMe storage and 16GB+ RAM. Our standard spec fits. For very high wallet load (thousands of concurrent users) consider the 32GB upgrade.
Setup
Bitcoin Core archival under, Fulcrum systemd above, RPC auth pre-wired, listen on 127.0.0.1 by default. Self-signed TLS cert preinstalled for electrum-tls.
Production Patterns
Many merchants and exchanges run Fulcrum as their primary Electrum backend. Pair with our Lightning node for end-to-end Bitcoin+Lightning merchant infrastructure.
Buy
$140/mo. See Electrs alternative, BTCPay companion.
