Mainnet

Programmable access for AI and Payments

Seal combines encryption and onchain policies to govern access to data, assets, and capabilities

Build with Seal

Make access part of public infrastructure

Public infrastructure is open by default. Seal brings built-in encryption and programmable access controls for data, AI, and digital assets.

Customizable access without custom infrastructure

Define who can access data, use capabilities, or authorize payments. Seal's programmable policies enforce the rules without custom security infrastructure.

Build your own trust network

Create MPC committees with operators you choose, giving your application a trust model tailored to its requirements.

Define your configuration. Seal handles the rest.

04

Store data
anywhere

Seal works with Walrus and other storage solutions. Encryption  is tied to the data itself, not its location.

Set policies that  enforce themselves

Define onchain access permissions using  Move smart contracts on Sui.

Encrypt at the source

Use identity-based encryption to protect content before it leaves the user’s environment.

Distribute key trust

Split key access across multiple nodes using t-of-n threshold encryption. Choose between independent key servers, an MPC committee, or a hybrid of both.

Enforce programm-able access

Apply time locks, token-gating, role-based access, or app-defined logic to control who gets access, when, and why.

Rotate and recover keys

Support key rotation, secure recovery, and long-term access without disrupting applications or encrypted data.

Integrate with developer SDKs

Use modular SDKs to integrate Seal into any stack without building your own infrastructure.

Run your own aggregator

Connect applications to MPC committees through your own aggregator while preserving the committee's distributed trust model.

Select your preferred trust model

Independent Key Servers

Operated independently

Client selects threshold

Maximum operator choice

Simple deployment

MPC Key Servers

Operators jointly protect a shared key

No operator holds the full key

Stable public key through committee rotations

Simplified trust management

Composable
Trust

Combine both approaches

Mix independent operators and MPC committees

Customize trust assumptions for your application

Activate smart control for every use case

Policy-governed AI

Encrypt sensitive data and control what AI agents can access, when, and under which conditions. Maintain user control while enabling agent autonomy.

Agentic commerce

Enable agents to make purchases, payments, and other financial actions within user-defined spending limits and approval policies.

Managed data access

Share premium content, either fully or partially, with verified subscribers who gain conditional access via NFTs, tokens, or recurring payments.

Time-locked transactions

Grant access to data like in-game content, DAO outcomes, or auction bids only after a fixed set  time or when conditions are met.

How Seal works

Seal offers robust encryption and on-chain access control for sensitive data
