What is CLINK?
CLINK (Common Lightning Interactions with Nostr Keys) defines Nostr-native standards for Lightning Network interactions, leveraging the protocol's built-in transport, identity, and encryption. This enables secure communication between Lightning nodes, wallets, and applications without traditional web infrastructure dependencies, while remaining web-friendly and facilitating self-custody.
This novel use of Nostr delivers a greatly enhanced user experience and unlocks new use-cases versus the status quo of things like LNURL, Bolt12, and NWC—without compromising sovereignty.

Why CLINK?
Existing Lightning interaction methods often require web servers, pre-shared secrets, or slow onion messages—creating friction, security risks, and barriers to adoption. CLINK leverages Nostr's cryptographic identity and event-based messaging to:
- Simplify user experience with direct, spontaneous interactions using familiar Nostr identifiers (NIP-05 addresses).
- Reduce infrastructure dependency by operating entirely over Nostr where desired.
- Enhance security by using signed events and web-of-trust identity.
- Foster a native ecosystem for Lightning and Nostr-powered apps.
