✅
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
