Anchor any document to the Base blockchain with a SHA-256 cryptographic hash. Property deeds, contracts, patents, evidence — get immutable proof that your document existed in its exact form at a specific moment. Used by governments from Dubai to Georgia.
We compute a SHA-256 cryptographic fingerprint of your file and anchor only that hash to the blockchain. Your original document never leaves your control, is never uploaded to any blockchain, and cannot be reconstructed from the hash. Full privacy with full proof.
Governments and enterprises worldwide already use blockchain for property, legal, and corporate records. Here's what you can anchor today.
Dubai Land Department already registers title deeds on blockchain. Prove property ownership, anchor deeds and titles, record mortgage liens, and create an immutable transfer history — no notary required.
Timestamp every version of every agreement the moment it's signed. When a dispute arises over which version was in effect, pull the blockchain proof certificate. NDA disputes, vendor contracts, partnership agreements — all settled with cryptographic proof.
Establish prior art and creation dates for patents, designs, trade secrets, and creative works. Bernstein.io proved this model — blockchain timestamps are accepted as evidence of first creation in patent disputes across the EU and US.
Preserve digital evidence with an unbreakable chain of custody. Timestamp screenshots, emails, financial records, and forensic reports at the moment of collection. Courts increasingly accept blockchain timestamps as proof of evidence integrity.
Record board resolutions, shareholder votes, and corporate decisions on an immutable ledger. The UAE DIFC already recognizes "Coded Contracts" — agreements executed by code. Anchor your corporate records to prevent backdating and disputes.
Anchor bills of lading, letters of credit, invoices, and customs declarations. Global trade runs on paper documents that get lost, forged, or disputed. Blockchain proof creates an immutable record that all parties can verify independently.
Investors require spousal consents, IP assignments, and advisor agreements before funding. These are standard template documents — no custom legal work needed. Anchor them on-chain so every party in your cap table can verify instantly during due diligence.
This is not experimental. National registries are live and processing millions of records.
Land Department registers property title deeds on blockchain. $16B tokenized real estate market projected by 2033.
National land registry on blockchain since 2016. 1.5M+ titles registered with SHA-256 hashes anchored to Bitcoin.
DMV placed 42M+ vehicle titles on blockchain to prevent fraud and reduce processing time.
UAE Verify platform validates any government document via blockchain hash — no paper copy needed.
Piloting blockchain for cross-border company verification and digital share registries.
Fully digitized national land cadastre and registry, backed by blockchain.
Enterprise-grade cryptographic proof with instant verification
Every file gets a unique 64-character fingerprint. Change a single byte and the hash is completely different. The same standard used by Georgia's national land registry and Bitcoin itself.
Your hash is permanently written to the Base L2 blockchain (built by Coinbase). The record is immutable, publicly auditable, and will exist as long as Ethereum exists.
Download a professionally formatted certificate with the hash, transaction ID, timestamp, QR code, and verification URL. Submit it to courts, regulators, or counterparties.
Every certificate includes a QR code. Anyone can scan it with a phone to instantly verify the proof on-chain. No account, no software, no trust required.
Share a unique URL with anyone — counterparties, auditors, judges. They can independently verify the hash and timestamp without any special access.
Full chain of custody from upload through hashing to blockchain anchoring. Every step is timestamped and logged for compliance, litigation, and regulatory use.
Upload any document — contracts, deeds, patents, evidence, corporate records. Your file is hashed locally and never stored on our servers or any blockchain.
We compute the SHA-256 hash of your file, producing a unique 64-character fingerprint. This is the same algorithm used by national land registries and banks worldwide.
The hash is written to the Base L2 blockchain in a permanent transaction. The on-chain record includes the hash, UTC timestamp, and transaction ID — immutable and publicly verifiable.
You receive a PDF proof certificate with the hash, blockchain transaction, timestamp, QR code, and verification URL. This is your portable, shareable proof of existence.
Anyone can verify the proof using the URL or QR code. They can also re-hash the original file themselves and compare against the on-chain record. Zero trust required.
"We had a dispute over which version of a purchase agreement was signed. We pulled the blockchain proof showing the exact document hash anchored three months before the other party claimed changes were made. Case closed."
Immutable proof at a fraction of traditional notarization costs
Traditional notarization costs $200+ per document and takes days. Blockchain proof is instant, stronger, and permanent.
