| Area | Capability |
|------|-------------|
| Performance | Handle 500+ simulated payments/sec |
| Resource use | < 200 MB RAM for 10 nodes |
| Portability | Linux, macOS, Windows (Go binary) |
| Extensibility | gRPC server plugins for custom business logic |
The lnd emulator utility is a software tool that simulates instances of lnd (Lightning Network Daemon) for development, testing, and experimentation with the Lightning Network without needing real Bitcoin testnet funds or live peer nodes. It provides a controlled, reproducible environment where developers can quickly spin up multiple nodes, create channels, send payments, and observe protocol behavior.
A lightweight CLI tool that emulates lnd (Lightning Network Daemon) behavior for local development and testing. It exposes a subset of lnd RPCs, simulates channels, invoices, payments, and node peers, and can run in memory or persist state to a local file. Useful for integration tests, frontend development, and sandboxing payment flows without running a full Bitcoin + lnd stack.
A robust emulator supports:
It must implement all essential LND gRPC methods:
lncli addinvoice --amt=50000
# Response includes payment_hash
lncli sendpayment --pay_req=<invoice> --force
The emulator will simulate:
