Notarize a patent, contract, or IP file by its fingerprint — anchored across five blockchains. The document never leaves your device. Anyone you share it with can verify it, no account needed.
Your browser computes the SHA-256 of the file. The file stays on your machine.
We Ed25519-sign an attestation and write the fingerprint to XDC, Base, Hedera, XRP & Stellar.
Send anyone the file. They confirm it here in seconds — unaltered and time-stamped. No account.
RILDocs is a blockchain notary for anything where proof that a file existed, unaltered, at a certain time matters. Create a tamper-proof, timestamped record in seconds.
Timestamp an invention disclosure or provisional patent draft to establish a verifiable date of creation and prior-art record.
Notarize a signed contract, NDA, or MSA so every party can prove the exact version and that it hasn't been altered.
Protect designs, source code, manuscripts, music, and artwork with a blockchain proof of authorship and existence.
Anchor audit logs, inspection reports, or any file you may later need to prove was genuine and unchanged.
Give counterparties a shareable link to independently confirm a document's integrity — without an account or upload.
Establish a public, time-stamped record of a draft, dataset, or research paper before you share or publish it.
A traditional notary and RILDocs solve two different halves of the same problem. Use both and you cover both — legal proof of who signed, plus cryptographic proof that the exact document is unaltered and existed by a certain date.
A commissioned notary verifies the signer's identity and witnesses the signature, then applies their seal — the government-recognized part.
Hash the finished, sealed document with RILDocs and you get a tamper-evident, independently-timestamped record — anyone can confirm it hasn't changed a single bit.
The notary covers what RILDocs can't (identity); RILDocs covers what the notary can't (tamper-evidence and a hard, un-backdatable timestamp).
How to do it: get the document notarized first, then scan or export the sealed version and notarize that file on RILDocs — so the anchor covers the notary's seal too. Keep the original file; RILDocs stores only its fingerprint, not the document. Note: RILDocs proves a document is authentic and unaltered — it does not validate that the notarization itself was genuine, and it is not a government apostille or a substitute for a court.
RILDocs isn't a black box. Every proof is built from published cryptographic and legal standards, and is verifiable with independent, off-the-shelf tools — not just on this website.
The document fingerprint uses the U.S. federal standard hash algorithm.
Each attestation is signed with a federally-approved digital signature algorithm.
A trusted timestamp token you can verify in any standard tool (e.g. openssl ts -verify) against our published CA.
Your certificate is a digitally-signed PDF (eIDAS PDF signature standard) with an embedded timestamp — validates in Adobe Acrobat.
The certificate is written as self-authenticating electronic evidence via hash-based digital identification — court-ready.
Aligned with U.S. law giving electronic records and signatures legal effect.
Data-minimization at the core — the document never leaves your device, so there's no personal data to process or breach.
Immutable records on XDC, Base, Hedera, XRP & Stellar — no single point of trust.
Roadmap for enterprise & EU buyers: eIDAS Qualified Trust Service Provider (qualified timestamps with EU legal presumption), SOC 2 Type II, and ISO/IEC 27001 — accreditations we're positioned to pursue. We describe only what's true today; “qualified” status is claimed only once earned.
After you notarize, you can mint your proof as an NFT straight to your own crypto wallet — a portable token you hold and can show to anyone. Only the SHA-256 fingerprint and timestamp go on-chain; your file and its name never do. Choose transferable, or lock it to you so it can never be moved.
It proves a document existed, unaltered, at a specific point in time. RILDocs computes a SHA-256 fingerprint of your file and records it on multiple blockchains. Anyone can re-fingerprint the file later and confirm it matches the immutable on-chain record.
No. Your file is hashed entirely in your browser. Only the 64-character fingerprint and the metadata you enter are sent — the document itself never leaves your device, so it stays completely private.
Send them the file and the verify link. They drop the file on the Verify page and RILDocs confirms whether it matches the notarized record — no account, no sign-up, nothing uploaded.
No. RILDocs proves a document's existence, integrity, timestamp and stated issuer — strong, court-usable evidence — but it does not by itself grant patent, trademark or copyright rights and does not replace an official government registry filing.
Yes — they complement each other. A notary verifies who signed (identity, government-recognized); RILDocs proves the exact sealed document is unaltered and existed by a certain date. Notarize the document first, then hash the finished, sealed version on RILDocs so the anchor covers the seal too. RILDocs proves integrity, not that the notarization itself was genuine, and it is not a government apostille or a substitute for a court.
Optionally, yes. After notarizing, you can mint your proof as an NFT to your own wallet on XDC — we cover the gas. It carries only the document's fingerprint and timestamp, never the file or its name, so nothing private is exposed. You choose whether it's transferable or locked to you (soulbound). It's a portable proof token, not legal title to the document.
Notarizing is free to start and verifying is always free. The free tier anchors your fingerprint on the XDC blockchain. Higher-volume, all-five-chain anchoring and API access are available for teams — contact us.
