Verify Integrity

Check if files or hashes have been sealed to the blockchain. Verification is always free.

📁

Upload Files

Drag and drop files or click to browse. We'll upload them for server-side hashing and check the blockchain.

#️⃣

Verify by Hash

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...

How Verification Works

  • • 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
