What is ETcH?

ETcH anchors the SHA-256 hash of your file on Ethereum mainnet, creating permanent, tamper-proof proof that your document existed at a specific date. No crypto wallet, no signup required — just drop your file, pay €2 via Stripe, and receive a self-contained proof kit ZIP containing the PDF certificate, the blockchain transaction, and all verification data.

ETcH is a direct alternative to the French enveloppe Soleau (INPI), notarised declarations, and services like OriginStamp or Bernstein — at a fraction of the cost, with instant delivery and independent verifiability on Etherscan.

Admissible as evidence in France (TJ Marseille, March 2025), the European Union (eIDAS 2), Italy (Law 12/19), Japan, Australia, Canada, and the United States.
