Lit Protocol lets you create and manage distributed cryptographic key-pairs for condition-based encryption and programmatic signing. A decentralized key management network, Lit can be used in place of centralized key custodians and other key management solutions.

Get started today!



To start building on Lit, check out the Lit SDK intro. For an in-depth understanding of the functionality provided, check out the API docs.

For references to the Lit Actions functions which can be accessed inside a Lit Action via the Lit.Actions object, check out the Lit Actions API docs.
