Seal

Why Seal? How it Works

Seal brings onchain access control and threshold encryption to developers, providing a secure and flexible way to manage sensitive data, whether it’s for encrypted storage, gated content, private messaging, or beyond!

A ton of Web3 apps need secure data access — whether for encrypted storage, gated content, private messaging, and more. Right now, options are:

• Web2 solutions (AWS KMS, GCP Cloud KMS)
• Niche Web3 products (wallet-specific encryption or purpose-specific privacy tool)

Seal offers a generalized, decentralized alternative that integrates easily with any app or protocol, without sacrificing flexibility or security.

• Onchain Access Control

Seal uses smart contracts written in Move to define flexible decryption policies, determining exactly who gets access to data and when.

• Threshold Encryption

Encryption keys are never stored in a single place. Instead, trust is distributed across a network of Seal key store services, eliminating single points of failure.

• Client-Side Encryption

Data is encrypted and decrypted locally by users, ensuring that sensitive information remains private.
