#️⃣

Already have a hash? Paste it below to check if it's sealed on-chain.

Tip: You can verify Merkle roots or individual file hashes.

Example: a1b2c3d4...

• If you upload files, they are sent to our API for server-side SHA-256 hashing and verification
• We compute a Merkle tree of the file hashes
• The Merkle root is checked against the blockchain
• Prefer not to upload files? Use “Verify by Hash” instead
