FakeWallet

Use the FakeWallet backend for development and testing without real Lightning payments.

FakeWallet simulates a Lightning node - invoices are auto-paid and payments always succeed. Use it for development and testing.

Configuration

bash

LNBITS_BACKEND_WALLET_CLASS=FakeWallet
FAKE_WALLET_SECRET=development-secret

When to use

Extension development - instant responses, no real node needed
UI testing - full workflow without real sats
CI/CD pipelines - automated tests against LNbits

VoidWallet

VoidWallet is the default backend. It accepts all API calls but doesn't process real payments. Use it for exploring the UI without any backend.

bash

LNBITS_BACKEND_WALLET_CLASS=VoidWallet

TIP

FakeWallet is best for development. VoidWallet is best for a first look at the interface.
