What is Lit Protocol

info

The Datil-dev testnet is now live and is superseding the Cayenne testnet. Check out the docs on migration to learn how you can start building on Datil-dev today.

Lit is a decentralized key management and compute network. Builders of apps, wallets, protocols, and AI agents use Lit to advance digital ownership with decentralized keys and private, immutable programs.

The system builds off of contemporary work in applied cryptography, sealed confidential hardware, and peer-to-peer networking to provide the maximum amount of control and privacy to developers.

Developers can use Lit to build apps with private data, intuitive onboarding and wallet management, and private, immutable programs that run based on the rules you set.

Get started with the Lit SDK.

Whitepaper. Open Source Node Code. Audit reports.

Use Cases

Lit Protocol can be utilized for various web3 applications, including:

Lit and ecosystem partners are building the next generation of identity and machine intelligence protocols and apps, all running on the open web.

Developer Tooling: Projects like AlchemyPimlicoOpenfortLens ProtocolOrbisSpheron, and Snowball are using the generalized services provided by Lit and making them available for developers in the form of SDKs, powering specific use cases like account abstraction, private data on web3 social, token gated chat, and mobile wallet tooling.

Data Marketplaces: Protocols like CheqdKaratDAOIndexDataverseOS, and Streamr use Lit for encryption in the commercialization of data, powering trustless marketplaces being built on blockchains and the open web.

Identity: Projects like OamoKrebitTerminal3HolonymAlphaCapture, and Gateway use Lit to power the selective disclosure of encrypted data and credentials, giving users the ability to control how their information is accessed, managed, and monetized.

Content Authenticity and LicensingBlockchain Creative Labs has integrated Lit for encryption  within their Verify platform as a secure signing backend, enabling content to be stored privately and under a proper license.

Digital Product NFTs: Teams like CrossmintMoleculeAlexandriaCharmVerse, and Anotherblock use Lit to meet their consumer demand for more creative utility for digital assets, like unlockable NFTs and for selective decryption for managing IP rights.

User Wallets: Lit is being used as a decentralized key management solution for wallets and onboarding experiences being built by the teams at Collab.LandInfinexObviousPatchWalletSilkMeteor, and Burnt. These products have taken the form of wallet applications, account abstraction signers, and embedded wallets on existing platforms like Telegram and Discord.
