Sim-ln
SimLN is an open-source Rust tool for simulating Lightning Network payment activity across real or mocked topologies. Compatible with LND, CLN, Eclair, it enables developers, researchers, and signet operators to generate realistic traffic for load testing, protocol evaluation, or synthetic data generation. This session introduces SimLN’s capabilities, demonstrates how to configure and run simulations using a simple sim.json file, and explores its flexible modes—from fully randomized traffic to precisely scheduled payments. Attendees will leave with a clear understanding of how to integrate SimLN into their own environments to accelerate testing and experimentation on the Lightning Network.
