Lit Protocol is a programmable runtime for everything that has to happen between an event and a signed action. Write JavaScript. Deploy it once. It runs inside a chain-secured TEE — pulling data from any source, executing your logic, and signing on any chain or HTTPS API. No backend to trust.

- Read — APIs, RPCs, price feeds, on-chain state across EVM, SVM, BTC, Cosmos
- Compute — your JavaScript, executed inside a hardware-attested TEE (Intel SGX), with keys that never leave the enclave
- Write — sub-second threshold signing on any chain or HTTPS endpoint, using a wallet bound to your action code or one you govern on-chain
The TEE's identity, the code it's allowed to run, and its signing authority are all governed on-chain. Speed of a backend, trust of a contract.
- Cross-chain tokens — watch burn events on one chain, sign the matching mint on another
- Custom price oracles — aggregate CEX + DEX feeds, sign once, deliver to multiple chains
- Prediction market resolvers — poll LLMs in a TEE, sign the consensus, post on-chain
- Compliance-gated transfers — screen recipients against sanctions lists before signing
