Customizable To Meet Enterprise Needs

Set up P2P dual-funded channels


CLN is the first Lightning implementation to support decentralized dual-funded channels.


Pay less to set up and run your node through balanced channels. CLN is efficient with your money and time.


Immediately route and receive payments upon opening channels. Rebalance your channels using on-chain assets through PeerSwap.


Benefit from added privacy


Blinded payment paths (experimental) maintain the privacy of CLN nodes when receiving payments. Never dox your node IP address or public key again.


Automatically increase privacy by using multi-part payments and randomizing selection of paths.


Select diversity of channels to help defend against deanonymization techniques.

Tailor your node based on your
business needs


Power-up your CLN node with plugins written in any popular programming language.


Spec-driven development maintained by the research team at Blockstream.
