A usable digital agreement names both parties, states the scope, price and dates, and carries both signatures with a timestamp; a lawyer is optional for simple deals and worth paying for on large or unusual ones.
Updated September 9, 2026
An agreement between a freelancer and a client is usable when a stranger reading it later can tell who agreed to what, for how much, and by when. Whatever tool you use, the text itself must cover five things.
For a simple deal, most freelancers do fine with a clear written agreement that both sides sign: a one-off logo, a two-week site build, a weekend of framing work. The terms are ordinary, and both people mainly want a shared record.
A lawyer earns the fee when the stakes or the structure are unusual. Five signals that you should get local advice before signing:
TrustChain does not replace that advice. It makes whatever you did agree to hard to dispute later.
Cost: free. A thread is better than nothing, but it is easy to dispute. Messages can be deleted or edited on one side, and there is no single final version both people clearly agreed to. When a client says "that is not what we discussed," scrolling through six weeks of messages rarely settles it.
Cost: a free tier or a monthly fee. A standard e-signature tool gives you one clean document with a signature on it. Two things are usually missing. First, there is no identity check: anyone holding the email link can sign, so you have a signature but no proof of who made it. Second, there is no independent, tamper-evident record: the file lives on the vendor's servers, and the only proof of its contents is the vendor's word. The comparison page sets TrustChain against e-signature tools and against hiring a lawyer.
Cost: free for one agreement a month, no card needed. TrustChain adds the two missing pieces. Both parties verify identity with a photo ID plus a selfie, which takes about two minutes, and an unverified account cannot sign. Once both have signed, the exact signed text receives a keccak256 fingerprint and a timestamped audit trail. Optionally, that fingerprint is anchored on the Polygon blockchain, and anyone with the public verification link can check the record without creating an account.
A Polygon anchor is optional. The free plan does not include one, and you can add one for $1. Pro ($19/month) includes 20 anchors and Elite ($49/month) includes 100. Full plan details are on the pricing page.
Every plan includes the AI Advisor, with 3 requests per month on the free plan. It does three things: explains a clause in plain language, flags wording that creates risk for you, and rewrites weak wording so it says what you meant. It is useful when a client sends a paragraph you do not fully follow.
The AI Advisor gives general guidance, not legal advice. Its answers are grounded in an actual statute only for the British Columbia Builders Lien Act; on every other topic it is a well-read assistant, not a licensed professional. When a clause matters enough that a wrong reading would cost real money, take it to a professional in your jurisdiction.
The cryptographic parts of a TrustChain record are verifiable anywhere: the fingerprint, the timestamps, the identity checks, and the Polygon anchor do not depend on where you live. Whether the agreement itself is enforceable depends on where the parties are and what they agreed, and TrustChain makes no claim about enforceability in any particular place. It also does not collect the money for you. What it does is make the record of the deal hard to dispute, so a payment conversation starts from agreed facts, not two competing memories. The security page describes how the record is protected.
