Do you need assistance like Polar, or would you prefer a code snippet for a mock gRPC server?
With the channel open, you can now generate an invoice on Bob’s node and pay it via Alice’s node. Developers hook up their applications (e.g., a Lightning-powered web app) to these local node ports using the generated Macaroon files and TLS certificates to test end-to-end functionality.

SimLN supports LND and Core Lightning (CLN) nodes and uses keysend to execute payments. You provide a configuration file ( sim.json ) that defines the nodes and the payment activity. For example: Do you need assistance like Polar, or would
Polar is a popular, user-friendly graphical interface (GUI) wrapper for Docker that serves as an excellent LND emulator utility. With Polar, you can drag and drop Bitcoin, LND, Core Lightning (CLN), and Eclair nodes onto a visual canvas. You can connect them, deposit mock funds, and open channels with a few clicks. It is highly recommended for developers who prefer a visual workflow over the command line. Best Practices for Testing with an LND Emulator
