Policy-managed data security

Seal offers robust data encryption and onchain access policies for Web3 apps

Make privacy part of public infrastructure

Decentralized storage is open by default. Seal brings built-in encryption and access control, so developers don't have to rebuild data security for their apps from scratch.

Customizable access without a custom setup

Define who can access your data and when. With Seal’s programmable policies and threshold encryption, no infra or custom tooling is required.

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 for secure and decentralized key management.

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

Rotate keys with envelope encryption and support flexible patterns for secure recovery and ongoing access.

Integrate with developer SDKs

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

Activate smart access 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.

Encrypted messaging

Build secure end-to-end chat in apps or trustless async communication between app components, even on public networks.

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.
