Seal anything.
Permanently. On-chain.

A document, photo, video, zip file — anything that can be hashed can be sealed. Immuta computes a SHA-256 fingerprint of your file locally in your browser, then registers it permanently on PulseChain.

How it works
Three steps. Permanent proof.

No account required. No server. Your file never leaves your browser.

01
Drop any file or paste text
Immuta computes a SHA-256 fingerprint in your browser. A document, photo, video, zip — anything. The original never leaves your device.
02
Pay $1 and seal
Pay $1 in USDC, DAI, or USDT. Sign with your wallet. Your fingerprint, timestamp, and note are written permanently to PulseChain.
03
Share your certificate
Get a shareable verification URL and downloadable PDF. Anyone can verify your seal on PulseScan independently — no Immuta account needed.
Use cases
If you've ever needed to prove something happened

This is for you.

The freelancer
You delivered the work. The client says they never approved it. You sealed the approved version the day they signed off. The argument is over.
The journalist
Seal source documents the moment you receive them. Prove they existed before your story broke — before any denial, before any legal challenge.
The creator
You wrote it, photographed it, composed it first. Seal your original work before publishing. Prove authorship before anyone else can claim it.
The tenant
Move-in day. Photograph every scratch, every mark. Seal the photos. When they try to keep your deposit — you have irrefutable proof of condition.
The small business
Seal contracts, invoices, and agreements the moment they're signed. No dispute about what was agreed, or when.
The developer
Timestamp code, architecture decisions, and IP disclosures. Prove prior art. Seal your work before anyone can challenge when it existed.
In the age of AI and disinformation —
Immuta it. Before they change it.

Manifesto
They told you to trust the institution.
To trust the notary. The bank. The registry. The middleman.
To trust the paper. The stamp. The signature of someone you've never met.

The future doesn't ask for trust. It demands proof.

Immuta is built on the belief that truth should be mathematical, permanence should be absolute, and verification should require no authority — only a blockchain. That the integrity of a record should not depend on the integrity of any single institution.

We build on PulseChain because decentralized infrastructure should be fast enough, and affordable enough, to be genuinely useful — not a privilege reserved for those who can absorb the cost.

We hold no data. We keep no files. We collect no information beyond what the blockchain itself records — your hash, your label, your wallet address. That's it. Nothing else exists.

Trustless
Immutable
Permanent
Obey the code.
Signed on behalf of
— The Human Race
Freedom through math. Immutable through code.
Transparency
We hold nothing.

No name. No email. No IP address. No analytics. No account. The only information that exists on-chain is what you chose to put there.

Who is Richard Heart?
Builder. Visionary. Polarising. Proven.

Founder of HEX, PulseChain, and ProveX — the man who set out to fix the money and fix the world. He built infrastructure designed to survive without him. Trustless by design. Permanent by nature.

Immuta exists in that tradition. We built on PulseChain because we believe in what is being built here.
