Autonomous
document signing
on Cardano

ROCKVALID is an autonomous file signing and signature verification system built on the Cardano blockchain.
Documents are cryptographically linked to verified identities and wallets — transparent, tamper-resistant and independently verifiable.
Built for privacy-first document verification.
No accounts. No document storage. No plaintext identity data.
