TL;DR: TRUE Vault is a new product from TRUE Original that lets anyone upload any file — PDF, image, audio, video, email, webpage capture — and secure it with a blockchain-anchored timestamp. The result is a permanent, shareable, verifiable proof that the file existed at that exact moment, unchanged. First file free; three files for 250 SEK.
Every day, people lose disputes not because they were wrong — but because they couldn't prove what they sent.
A PDF altered after it left your hands. A notice a recipient swears never arrived. A contract where both parties somehow have different versions. An audit report where the numbers "changed." These aren't rare edge cases. They happen in every industry, every week, to people who had no reason to think they needed proof until the moment they did.
The question "how do I prove this document existed, unchanged, on the day I sent it?" has never had a good answer. Until now.
TRUE Vault gives every file a permanent, blockchain-anchored timestamp — shareable, independently verifiable, forever. Upload any file. Get proof. No registered mail. No legal friction. No trust-me timestamps.
TRUE Vault is a digital vault that proves any file existed at a specific moment, unchanged, secured by you.
Upload a PDF, an image, an audio recording, a video, an email — anything. TRUE generates a unique digital fingerprint of the file and anchors it on blockchain. From that moment on, you have a permanent, shareable, verifiable proof that the file looked exactly the way it did, at exactly the time it did, secured by you.
TRUE Vault sits inside the broader TRUE Original ecosystem — the same platform that has already secured 500,000+ documents for 200+ organizations across 15+ countries. Until now, that infrastructure was used to issue diplomas, certificates, licenses, and other credentials on behalf of organizations. TRUE Vault opens it up. Now anyone — an individual, a lawyer, a designer, a journalist, a small business, a global enterprise — can secure their own files with the same proof.
It is, among other things, a modern alternative to registered mail. But it is bigger than that. Registered mail proves something was delivered. TRUE Vault proves what was delivered. Byte for byte.
This part matters. We want to be precise.
TRUE does not verify that the content of a file is true, correct, or legitimate. Someone could upload a fabricated contract, a misleading image, or an invented press release, and TRUE has no opinion on whether the content is honest.
What TRUE Vault proves are three things — nothing more, nothing less:
The proof reads, in plain language: "This file is unchanged since [date]. Secured by [name] on [date]."
That's the contract we make with every file. It's narrow on purpose. The narrower the claim, the stronger the proof.
One practical note: the sooner you secure a file after creating it, the stronger the proof. A contract secured the moment it is signed, a demand letter secured the moment it is sent, a design file secured the moment it is delivered — each one becomes harder and harder to dispute the longer it sits in the chain.
1. Upload. Drag any file into TRUE Vault. PDF, image, audio, video, Word document, email — it doesn't matter what kind.
2. Secure with blockchain. TRUE creates a unique digital fingerprint (SHA-256) of the file and anchors it permanently on blockchain. The timestamp is fixed. It cannot be moved or rewritten.
3. Get your proof. You receive a permanent proof URL. That URL is your proof — shareable, verifiable, forever.
4. Share on your terms. Send the link to whoever needs it. Choose the visibility: public for anyone with the link, private for just you, or password-protected. Add a recipient if you want a digital confirmation: "I have seen your file."
5. Verify anytime. Anyone — opposing counsel, a client, a journalist, a regulator, your future self — can verify the file through TRUE Verify. No account. No cost. Just a quick check that returns unchanged or changed.
TRUE Vault is built for any moment where the question "what exactly did you send, and when?" could matter. Here are five of the people we built it for.
You send a demand letter to opposing counsel. Weeks later, the other side claims they never received it, or that the wording was different from what you now produce. With TRUE Vault, you can show exactly what was sent, when, and that the contents have not been altered. A timestamp on the chain, not a paper receipt in a drawer.
You send a design proposal to a prospective client. Three months later, the client launches a near-identical design and claims it was their own concept all along. Because you secured the file in TRUE Vault the day you sent it, you can point to a blockchain-anchored timestamp from three months before the launch. The file existed. It was yours. It hasn't changed.
You receive a source document, a leaked report, or a press release that you intend to write about. The story may not run for weeks, and the source material may be quietly revised in the meantime. Secure it in TRUE Vault the moment it lands. You now have provable evidence that you held this exact version of the file on this exact date.
You deliver an audit report to a client. Months later, the client claims the report contained different conclusions, or different numbers. With TRUE Vault, the deliverable is timestamped and locked. The file you delivered is identical, byte for byte, to the one being disputed. There is no argument to be had.
You send a tenant a notice — a rent increase, a termination, a formal warning. The tenant says it never arrived, or that the terms were different. The notice was secured in TRUE Vault before it left your hands. The proof page shows what was sent, when, and to whom.
You publish a press release on behalf of a client. Someone later quotes you incorrectly, or claims the wording changed after publication. The timestamped original sits in TRUE Vault, unaltered. There is no ambiguity about what was written.
These are six different jobs, six different situations. The product is the same. One vault, one proof, one verifiable record.
For decades, the closest thing to "I can prove I sent this" has been registered mail. In Sweden, that means PostNord's rekommenderat brev. More recently, digital registered mail services such as Kivra have offered a faster path. Each of these has its place. Here is a fair comparison.
| PostNord registered mail | Kivra digital registered mail | TRUE Vault | |
|---|---|---|---|
| Proves something was sent | Yes | Yes | Yes |
| Proves what was sent | No | Partial | Yes — byte for byte |
| Recipient needs an account | No | Yes (Kivra) | No |
| Requires BankID / national ID | No | Yes | No |
| Works outside Sweden | No | No | Yes, globally |
| Proof is permanent | Paper receipt | No | Blockchain — forever |
| Digital receipt of viewing | No | Yes | Yes |
| Cost | ~150 SEK per letter | Included in Kivra | First free / 3 for 250 SEK |
Registered mail proves a thing arrived at an address. It does not prove what was inside the envelope. TRUE Vault proves both the file and the moment — and the proof is anchored on blockchain rather than printed on a receipt that can be lost.
Digital registered mail through Kivra is fast and convenient if both sender and recipient are in Sweden, both have BankID, and both have Kivra accounts. TRUE Vault is built for the cases where any of those things isn't true: cross-border work, recipients without a Swedish ID, situations where you need the proof to be permanent and independently verifiable, by anyone, forever.
We've kept the entry point deliberately simple.
For context, a single PostNord registered letter costs around 150 SEK and proves only that an envelope was delivered. Three TRUE Vault proofs cost 250 SEK and prove exactly what was sent — down to the byte — anchored on blockchain, verifiable globally, forever.

TRUE Original is now three products, each doing one thing well.
The original product. Organizations create, issue, and manage digital documents — certificates, diplomas, awards, licenses, memberships, transcripts — on their own branded domain. Each document is blockchain-secured, beautifully designed, and verifiable by anyone with a QR code or a link. This is what 200+ organizations across 15+ countries already use to issue credentials.
The new product. Anyone — an individual or an organization — can secure their own files with a blockchain-anchored timestamp. Upload, secure, share on your terms. Use it for demand letters, design files, audit reports, press releases, source documents, notices, contracts, recordings, photographs — anything where the question "what was sent, and when?" might matter later.
The free, open verification tool. Anyone — no account required — can drop a file at trueoriginal.com/verify and get an immediate answer: unchanged, changed, digitally signed elsewhere, or unverifiable. Verify is the public counterweight to the proofs that come out of Documents and Vault. It is, and will always be, free.
Three products. One mission: make digital files provable.
Files are still the medium through which most consequential things happen. Contracts. Demand letters. Audit reports. Press releases. Designs. Notices. Source documents. Inspection records. Board minutes.
For most of the digital era, the answer to "how do I prove this file existed in this exact form on this exact date?" has been: trust me. A timestamp on an email server. A modification date in a file system. A receipt from the post office that proves the envelope arrived but not what was inside.
The era of trust-me digital files is ending. The infrastructure to prove a file — independently, permanently, globally — now exists. TRUE Vault is our contribution to that shift.
We are a Swedish company, founded in 2020, eIDAS compliant, working with organizations across 15+ countries. We've spent five years building the blockchain plumbing behind half a million issued documents. TRUE Vault opens that plumbing up to anyone with a file worth proving.
Yes — easily. A standard PDF has no built-in mechanism to detect whether it has been changed after creation. Metadata timestamps can be edited, email threads can be manipulated, and file modification dates can be reset. Without a third-party, blockchain-anchored timestamp, there is no reliable way to prove a PDF is unchanged. TRUE Vault creates an independent, cryptographic fingerprint of your file the moment you secure it. Change a single byte — a comma, a number, a space — and the fingerprint changes completely. That mismatch is the proof.
The most reliable method is to create a tamper-evident timestamp before or at the moment of sending. TRUE Vault does this by generating a SHA-256 hash of your file and anchoring it on blockchain. The timestamp cannot be backdated or changed after the fact. When you share the TRUE Vault proof link with a recipient, anyone — a court, a counterparty, a regulator — can verify that the file they hold is byte-for-byte identical to the one you secured, and that it was secured before the dispute arose.
In most jurisdictions, a blockchain-anchored timestamp is accepted as evidence of when a file existed. It is not a legal signature — TRUE Vault does not replace a contract signature or a court filing. What it provides is independent, third-party verifiable evidence of: (1) the exact content of a file at a specific moment, (2) who secured it, and (3) that the content has not changed since. This class of evidence is increasingly recognised in civil disputes, arbitration, and regulatory proceedings across Europe and internationally.
Registered mail proves that an envelope arrived at an address. It does not prove what was inside the envelope, and it cannot prove the contents have not been altered. TRUE Vault proves the exact content of a file — byte for byte — at a specific timestamp, verifiable by anyone, globally, forever. It also records whether and when a recipient viewed the file. For cross-border situations, recipients without a national ID, or any case where the content itself is what matters, TRUE Vault provides proof that registered mail cannot.
No — and this distinction matters. TRUE Vault proves that a file existed in a specific form at a specific time, secured by you. It does not prove that another party agreed to the contents. For contracts requiring mutual agreement, you still need a signature — whether wet ink or a qualified electronic signature. What TRUE Vault adds is proof that the version you sent is identical to the version now being disputed. The two tools work together: sign the contract, then immediately secure it in TRUE Vault to lock the version permanently.
When you send a TRUE Vault link to a specific recipient, you can request a digital confirmation — a record that the recipient accessed the proof page. This creates a timestamped record of: when the file was secured, when the link was sent, and when the recipient viewed it. This is functionally stronger than a registered mail return receipt, which proves only that someone at an address accepted an envelope — not that a specific person read a specific document.
Yes. TRUE Verify is free and requires no account. Anyone — opposing counsel, a journalist, a regulator, a client — can go to trueoriginal.com/verify, upload the file in question, and get an immediate answer: unchanged or changed. If the file has been altered in any way since it was secured, verification fails. This open, third-party verification is what makes the proof meaningful: it doesn't rely on trusting TRUE — it relies on blockchain mathematics that anyone can check.
Any file. PDF, Word document, image, audio recording, video, email export, webpage capture — format does not matter. TRUE Vault creates a fingerprint of the file's binary content, regardless of type. The most common use cases are contracts, demand letters, audit reports, design files, press releases, inspection records, board minutes, and notices. If the question "what exactly did this file contain, and when?" could ever matter — secure it.
No. DocuSign and similar tools are signing platforms — they collect and record agreement between parties. TRUE Vault is a proof-of-existence platform — it records that a specific file existed in a specific form at a specific time. The two solve different problems. DocuSign answers "did both parties agree?" TRUE Vault answers "what exactly did they agree to, and has it changed since?" Used together, they close both gaps.
The blockchain record is permanent. There is no expiry date on a TRUE Vault proof. A file secured today can be verified in ten or twenty years, as long as the original file is available for comparison. This permanence is what distinguishes blockchain-anchored proof from email timestamps, file modification dates, or server logs — all of which can be altered or deleted by the parties who control those systems.
The first document is free. It takes about a minute.
