Process
Three steps to permanent proof
Upload
Drop any file — contract, photo, code, design. We never store your document; only its cryptographic fingerprint.
Timestamp
Your file's hash is anchored to a blockchain block, creating an immutable record of exactly when it existed.
Certify
Receive a signed certificate and a verifiable proof anyone can check — independently, forever, without us.
Why DeepStamp
Built for trust, designed for speed
Tamper-Proof
SHA-256 hashing means any change — even one byte — produces a completely different fingerprint. Fraud is mathematically impossible.
Instant Certification
Timestamps are issued in seconds. Your proof is ready before you can open a new tab — no waiting, no queue.
Forever Verifiable
Your certificate can be verified by anyone, independently, without DeepStamp — the proof outlasts us.
