Digital evidence with a proven date, without leaving your office.

Screenshots, emails, drafts and signed documents change hands all the time — and when a dispute arises, the question is always the same: is this the original file, and did it exist on that date? Docmint records the integrity and precedence of any document in seconds, with technical proof the other side can check on their own.

The challenge

Where proof usually breaks down

"That screenshot could be edited"

Screenshots and digital files are easy to alter. Without an integrity record, authenticity becomes an argument — and costs time.

Which version was valid that day?

Long negotiations produce dozens of drafts. Proving which text existed on a given date often depends on memory and good faith.

Notarization isn't always fast enough

A notary is the classic answer, but it's expensive, requires a visit and can't keep up with content that may vanish at any moment.

How Docmint helps

Technical proof that's simple to create and easy to check

Verifiable integrity

The file's SHA-256 fingerprint is written to the blockchain. Any change, however small, no longer matches the record.

A date nobody controls

The timestamp comes from a block on the Base network — public, immutable and independent of Docmint, your client and the other party.

Confidentiality preserved

The document is never uploaded. Only its fingerprint leaves your computer, respecting attorney–client confidentiality.

Ready for experts

The receipt includes the hash, transaction, block and independent verification steps, so a technical expert can check it without us.

What to record

Files worth recording

Signed contracts and amendments
Drafts and negotiation versions
Opinions, briefs and filings
Screenshots of chats, websites and social media
Audio and video recordings
Minutes, notices and announcements
Expert reports and technical documents
Internal policies and terms of use

Any format works: Docmint records the file's fingerprint, not its content.

In practice: preserving a conversation before it disappears

Your client receives threats through messages that could be deleted at any moment.

1
You export the chat and save the screenshots and export file in a folder.
2
Drop everything into Docmint, which records the files as a batch in a single transaction.
3
Within seconds you get a receipt per file, with the block date and a verification QR code.
4
Files and receipts go with the filing; the other side can check authenticity at /verify.

Best practices

Record the file as soon as you obtain it, before any editing or conversion.
Keep the original in a protected folder and always work on copies.
For batches, use a title that identifies the matter (e.g. an internal case number).
Don't put personal or confidential data in the title or description — they are public.
For high-stakes facts, combine the record with notarization: they complement each other.

What the law says

Courts in many jurisdictions accept electronic documents as evidence and weigh their reliability. A Docmint record is technical evidence of integrity and precedence; it has no notarial authority and does not replace notarization or official registration where the law requires them.

Frequently asked questions

Does it replace notarization?

No. A notary carries public faith; Docmint provides fast, affordable technical proof of integrity and date. Often it's enough; for sensitive matters, using both is the strongest combination.

Can I record client documents with sensitive data?

Yes. The content never leaves your computer — only the fingerprint is recorded. Just avoid personal data in the title and description.

How does the other party check the record?

With the file and the receipt, anyone can verify at docmint.app/verify — or fully independently by computing the SHA-256 and looking up the token on the blockchain.
