Lnd Emulator Utility Work Link
Are you trying to a specific error in your simulation?
Start small: spin up a two-node emulator today. Write a simple Python script to monitor channels. Inject a failure. Watch your utility react. That single cycle of emulation → utility work → refinement will pay dividends the first time a real channel acts up on mainnet. lnd emulator utility work
You can inject edge cases that occur once every 10,000 transactions on mainnet, but force them to happen on every test run. Are you trying to a specific error in your simulation
