Integrate Your Way
Seal documents via REST API, use the CLI from your terminal, protect AI agent skills, or automate via the upcoming Office 365 integration.
Verify files for free today, and automate sealing for SharePoint & OneDrive with the upcoming Office 365 integration.
Protect agent skills with Merkle roots, BRC-103 identity keys, and on-chain proofs.
Single binary for sealing, verifying, and managing on-chain skills from your terminal.
Seal and verify via REST. Upload files or submit pre-computed hashes — verify is always free.
How It Works
Seal
Files are cryptographically hashed and combined into a Merkle root. With hash-only mode, your data never leaves your machine — only the fingerprint does.
Anchor
The Merkle root is written to the blockchain in an immutable transaction — a permanent, timestamped proof of integrity.
Verify
Anyone can independently check that files match their on-chain proof. Tampered files fail instantly. No trust required.
