Web3 needs better data security.
Seal, a decentralized secrets management (DSM) service, is now live on Sui Testnet!
Think of it as onchain access control + threshold encryption for sensitive data.
What’s the problem?
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 gives builders a generalized solution that’s decentralized, flexible, and works with any app.
How does Seal work?
Onchain Access Control 🔑 — Flexible policies written in Move smart contracts control who gets decryption keys and when
Threshold Encryption 🏗️ — No single point of failure; trust is distributed across multiple Seal key store services
Client-Side Encryption 🔐 — Users encrypt/decrypt data locally, keeping it private
Seamless Storage Integration 📦 — Agnostic to where data is stored, but works with decentralized storage like Walrus
Why does this matter?
With Seal, Web3 apps can:
✅ Protect user data without relying on centralized key management
✅ Gate content for creators, NFT owners, DAOs, or private communities
✅ Secure private messaging for dApps
✅ Enable time-locked asset transfers with encryption-based handovers
Builders, Seal is plug-and-play security
No need to reinvent encryption. Just use the SDK & get:
Scalability (threshold encryption = no single point of failure)
Transparency (access control is onchain)
Flexibility (policies work across use cases)
Example use cases 🛠️
Gated content — Monetize premium content on-chain
Game logic — Encrypted assets and gated story progression
Web3 messaging — End-to-end encrypted chats
Secure NFT transfers — Set time-locks or dynamic access rules
