Try on regtest (safer / free)

Before mainnet, use regtest to try the Quote → Pay → Stream flow. There are two routes:
  • A) Automated (integration tests): tests auto-start bitcoind (regtest) + 2x lnd
  • B) Manual (devnet): run ./scripts/devnet locally and operate it by hand

​
Prerequisites (no Nix)

  • Go 1.24.4+
  • bitcoind / bitcoin-cli on PATH
  • lnd / lncli on PATH

​
A) Automated (integration tests)

cd go-lcpd

LCP_ITEST_REGTEST=1 go test ./itest/e2e -run Regtest_LNDPayment -count=1 -v
LCP_ITEST_REGTEST=1 go test ./itest/e2e -run Regtest_LNDCustomMessages -count=1 -v
LCP_ITEST_REGTEST=1 go test ./itest/e2e -run RequesterGRPC -count=1 -v
Details: regtest-integration.md

​
B) Manual (devnet)

​
1) Start devnet (bitcoind + 2x lnd)

cd go-lcpd
./scripts/devnet up
./scripts/devnet status
First time only (interactive): 
./scripts/devnet lncli alice create
./scripts/devnet lncli bob create

​
2) Funding / channel / smoke checks

The manual steps are longer; see devnet.md.

​
3) Start go-lcpd → run oneshot

For Provider configuration (YAML) and profiles, see configuration.md.

​
Data/logs and cleanup (destructive)

  • devnet state/log: ./.data/devnet/
To rebuild from scratch (destructive): 
cd go-lcpd
./scripts/devnet down
rm -rf ./.data/devnet
