Hash, encrypt, and anchor your critical documents on the blockchain — with one upload. Legally defensible proof that can never be altered, deleted, or disputed.
Trusted for contracts, NDAs, invoices, change orders, and legal filings
One upload. Permanent proof. Three simple steps.
Drop any document (PDF, DOCX, images, up to 100MB). We instantly compute its SHA-256 fingerprint client-side.
The hash is written permanently to a public distributed ledger. Timestamped, immutable, independently verifiable by anyone.
Share a verification link. Anyone can confirm your document's authenticity — without ever seeing the file itself.
Built for legal, construction, and finance professionals who need indisputable records.
Your actual files never leave your device. We only receive and anchor the cryptographic hash. Total privacy, guaranteed.
Once anchored on the ledger, the record cannot be backdated or altered. It's a mathematically proven snapshot in time.
Anyone can drop a file into our verifier to check if it matches the blockchain record. No account required to verify.
Pay once. Proven forever. No recurring storage fees.
For occasional legal proofs.
Per document anchored.
For teams handling critical records.
Includes 20 anchors/mo.
Drag and drop any file into our public verifier to instantly check its cryptographic proof against the blockchain ledger.
