Lit

Lit Protocol fills a critical gap in the Web3 technology stack by providing a decentralized layer for secret management, making signing and encryption a native computing primitive. Instead of relying on centralized custodians, keys are created via a Distributed Key Generation (DKG) process, fragmented into shares, and stored across a network of independent nodes. Each node runs within a TEE, providing hardware-level isolation and protection, while collectively meeting a two-thirds threshold to execute any signing or decryption request.

This architecture enables secure, policy-driven control over assets and data. Developers can write Lit Actions to enforce custom rules, such as who can access encrypted files, how and when transactions are signed, or which cross-chain operations are permitted. These functions can fetch on-chain and off-chain data, execute complex logic, and operate entirely without exposing the underlying keys.

Key use cases include Universal Accounts—wallets that operate seamlessly across Bitcoin, Ethereum, Solana, Cosmos, and more—User-Owned Data systems where access is dynamically controlled, and Agent Wallets that power autonomous yet verifiable AI agents. Partners such as Emblem Vault, Beacon Protocol, Tria, and Genius Bridge already use Lit Protocol to deliver interoperable, secure, and censorship-resistant services.

In the broader decentralized security landscape, Lit competes with solutions like Threshold Network and Shamir Secret Sharing-based systems, but stands out for its programmable JS execution layer, native multi-chain support, and deep integrations with AI and interoperability projects. By blending cryptography, decentralization, and developer flexibility, Lit Protocol is becoming a foundational security layer for the next generation of blockchain and AI applications.

Lit Protocol offers powerful security and programmability features:

• Threshold MPC + TEE Security: Keys are never fully exposed, staying fragmented and encrypted at all times.
• Lit Actions: Immutable JavaScript functions to define custom signing, encryption, and access control policies.
• Universal Accounts: Multi-chain wallets that work seamlessly across different blockchains without custodians.
• Agent Wallets: Verifiable AI and automation agents with user-defined permissions.
• User-Owned Data: Build apps where users retain full control over their private data.
• Cross-Chain Interoperability: Program private keys to bridge assets and execute cross-chain operations securely.
• Developer-Friendly: Robust SDK, APIs, and documentation for quick integration.

To start building with Lit Protocol:

1. Visit the Lit Protocol website and review the Docs section.
2. Set up an account on the Datil mainnet or testnets to start experimenting with Lit’s capabilities.
3. Install the Lit SDK and follow the quickstart guides to make your first signing or decryption request.
4. Create Lit Actions to define policies, workflows, and access control logic.
5. Integrate Lit into your app for use cases like universal accounts, agent wallets, or encrypted data sharing.
6. Join the Lit developer community on Discord and Telegram for support and collaboration.
