₿ Hello, Bitcoin community.

I’m currently working on a personal project and want to start testing Lightning Network on testnet (Testnet4). I’ve already tested Bitcoin testnet and successfully made some transactions, so now I’d like to do the same on LN — opening channels and generating invoices without using real BTC.

Right now, I’m running a BTC Server on Umbrel along with the LN Node app, which I use to get the connections for integration with my app. My goal is to create and test LN channels, and to issue and pay invoices in a full test environment.

Could anyone share documentation, practical guides, or examples on how to open channels, manage liquidity, and issue/receive invoices on the Lightning testnet? Any step-by-step tutorials, useful commands, or links to official resources would be greatly appreciated.

Also, here’s my project in case you’d like to take a look or share feedback https://github.com/ZatoBox/main

Thanks in advance! ⚡
