Our mission
We're building proof
that agreements happened.
TrustChain keeps a record of agreements between people that neither of them can quietly rewrite.
Why we exist
The internet made collaboration easy.
It didn't solve proof.
People work together across borders every day: freelancers and clients, founders and contractors, people making commitments that matter. But the record of what was agreed usually lives in one place, controlled by one side, with no independent source of truth.
I didn't build TrustChain from a market report. I built it because I lived the problem, again and again. Work delivered, payment vanished. Terms quietly rewritten after the fact. No record strong enough to fight back with, and no neutral standard to point to.
I also spent years around crypto, where I saw both sides of what a public ledger can do: how useful it is, and how easily it gets turned against people. That taught me what most people miss. The technology was never the problem. The problem is that in 2026 there's a standard for everything except a deal between two people. So I set out to build one, and to put this technology on the side of the honest for once.
The problem is structural. Notarization and timestamping services do exist, and the cryptography has been settled for years, but they are built for people who already know they need them, and they stop at proving that a file existed. Nothing joins the whole chain for an ordinary two-person deal: a verified identity on each side, the terms they actually agreed, proof that neither can quietly change them, and a plain-language read of what is being signed. That is the gap TrustChain is built for.
What's broken
The current system rewards whoever holds the file.
When agreements exist only as files inside platforms, the proof of what was agreed lives alongside whoever controls the document. There is no neutral record.
When disputes arise, the stronger side, the one with better documentation, better access or simply more leverage, tends to win. That isn't resolution. That's information asymmetry.
- Digital agreements have no neutral custodian
- Files can be edited or replaced, often without any trace
- Platform access can be restricted or revoked at any time
- Screenshots and memory are easy to dispute
- Disputes come down to word against word, and without proof the stronger side wins
What we're building
A neutral layer beneath every agreement.
Your agreement isn't made public, and it goes to OpenAI only when you ask AI Advisor or Pip for help with it. We store it so TrustChain can work. When a signed record is anchored, we fingerprint its ID, title, terms, amount and both parties' account IDs and write that fingerprint, with the record's ID and two empty wallet slots, to Polygon, a public blockchain neither party controls. The terms stay private. The proof stays public.
Think of it as a postmark: it shows the record existed in that exact form on that date, and any later change would produce a different fingerprint. The dated entry on Polygon does not depend on TrustChain staying online.
The verifier and the contract are open source. Read the code on GitHub.
- End-to-end encrypted negotiation: the keys live on your devices, so only the people in the chat can read the conversation that shapes the deal.
- A cryptographic fingerprint for every anchored agreement: your private terms stay private, while a dated public record shows the agreement existed in that exact form.
- A signed record that neither party can quietly alter
- Dated records, with an optional Polygon anchor that doesn't depend on TrustChain staying online
- An anchored fingerprint shows a record existed on a date, without revealing its terms
Answers that cite their source
An assistant that shows its work,
or admits it cannot.
Most AI legal answers are confident and unverifiable. You are told what the rule is with nothing to check it against, and the parts that are wrong look exactly like the parts that are right.
Where we have indexed the legislation, the assistant answers from the statute text itself and shows you where the answer came from: the act, the section, the consolidation date of the version it is quoting, and a link straight to the official government source. It also flags provisions whose amendments have been passed but are not yet in force, the case most likely to make a correct-sounding answer wrong.
And where it has no governing provision, it says so and stops, instead of filling the gap with something plausible. Refusing is the harder behaviour to build and the more useful one to have.
Indexed coverage today is British Columbia, beginning with the Builders Lien Act. Everywhere else the assistant gives general orientation and says plainly that it is not citing governing law.
Where this goes
Every digital relationship deserves a source of truth.
We started with freelance and service agreements, where trust breaks down most often and people have the least protection. But the problem exists anywhere people make commitments digitally.
The long arc is a world where proof of what was agreed outlasts any platform, any relationship and any dispute, and stays with the people it belongs to.
- Freelancers and clients with a clear record of what was agreed, and a public link to check it
- Contractors and companies with proof that outlasts the engagement
- Partners and collaborators who need more than a handshake and a shared file
- Any relationship where what was agreed matters more than who holds the document
