Elias had been a router back then. A good one. He had threaded payments through the mesh like a needle through silk. He had a channel open with a woman named Sarah. Just a small channel. 500,000 satoshis. Back then, it was lunch money. Today, it was a life savings. | Feature | LND Emulator Utility | Regtest

Hi there,

The is a software tool—often a command-line interface (CLI) application or library—that mimics the behavior of a real LND node. It provides the same gRPC and REST APIs, the same channel management logic, and the same payment lifecycle, but runs entirely in memory or using lightweight simulated database backends.

package for writing integration tests against a local cluster of simulated nodes. code example
