What is Lit Protocol
Lit Protocol is distributed cryptography for encryption, compute, and programmable signing. As a generalizable key management layer, Lit providers developers with a comprehensive toolkit for managing sovereign identities on the open Web.
Core Functionality
Lit Protocol provides developers with two core services:
Encryption and Access Control: Lit enables the client-side encryption and decryption of data by harnessing on or off-chain conditions, without relying on a centralized key custodian. Use Lit to securely store data on the open Web by getting started with encryption and access control.
Programmable Signing: Lit can be used to program complex signing automations or provide seamless wallet onboarding experiences using Programmable Key Pairs (PKPs) and Lit Actions. PKPs are MPC wallets generated and distributed across the Lit network, while Lit Actions are JavaScript functions dictating when, why, and what a PKP wallet will sign. Get started with PKPs and Lit Actions.
Use Cases
Lit Protocol can be utilized for various web3 applications, including:
- DeFi: Conditional transaction execution, recurring payments, liquid staking solutions, and more.
- Infrastructure: Cross-chain bridges, oracles for off-chain data, privacy-preserving transactions, and AA wallet signers.
- Sovereign Data: Verifiable credential issuance and selective disclosure for user data.
- Web3 Social: Private data in social apps, token-gated video streaming, decentralized chatbots, and on-chain reputation building.
- Gaming: Wallet abstraction, condition-based rewards, and private data in multiplayer games.
- Token Gating for Web2 Apps: Token-based access control for Shopify, Zoom, Google Drive, and WordPress.
