Confidential, verifiable execution.
Lit runs your code in confidential hardware. You can verify the software, connect to any data source, and control what the code can do and send. Use it for crypto transactions, or for AI training and inference.
Building with Lit
“Lit is a cornerstone in our vision for frictionless, chain-abstracted payments.”
“Lit Protocol's revolutionary programmable encryption transforms Emblem Vault into a living ecosystem where AI agents like Hustle operate autonomously across chains.”
“Lit Protocol enables us to provide unprecedented levels of data sovereignty and interoperability by using programmable keys that run on rules established by our protocol.”
“With Genius Terminal, Lit's programmable encryption enables non-custodial multi-wallet management, DCAs, limit orders, and stop losses.”
Wallet infrastructure
You decide what your wallets can sign.
Write code that reads from APIs or blockchains and decides when a wallet can sign. Your on-chain account controls which code is authorized, and Lit runs it inside confidential hardware.
Keep keys private and verify what runs.
Lit derives and uses keys inside confidential hardware, isolated from the host. You can check the runtime’s code hash against an approved release.
Set permissions you can inspect.
Choose which code can use a wallet. Your account controls those permissions through contract state that anyone can inspect.
AI training & inference
Keep AI workloads private and verifiable.
Tell us what you want to train or run and what data it needs. We’ll work with you to define the private environment, verify its software, and set rules for data access and outputs.
Training
Plan how to train or fine-tune models with sensitive data.
Inference
Work with us to protect prompts, context, and responses while your model runs.
Data control
Connect private datasets and external services, then define what the workload can read, send, or return.
Infrastructure
We make open, verifiable infrastructure easy to use.
We manage the hosted system, abiding by the on-chain process for approving protocol updates. You can inspect the source, see which releases are approved, and verify the software running. Connect through the API to get started.
Wallet policy and runtime approvals are separate.
Build on a foundation you can verify.
Start with the API for crypto, or work with our team on confidential AI training and inference.
