Common questions freelancers ask about Chaindoc
Answers on contracts, IP protection, and client signing workflows for freelancers. More at our support page.
Freelance contract blockchain signing means every contract you send (proposal, NDA, statement of work, retainer agreement) gets a unique SHA-256 hash anchored on a public blockchain at the moment of signing. The client opens the link, signs in seconds from any device, and the platform records the signer's identity, IP, timestamp and the document hash on-chain.
From that point on, anyone can verify the contract has not been altered — protecting both you and the client without trusting a middleman. The whole thing is legally binding under ESIGN Act, UETA and eIDAS.
Yes. Blockchain contracts for freelancers are legally binding in every jurisdiction that recognises electronic signatures — including the United States (ESIGN Act, UETA), the European Union (eIDAS Article 26 Advanced Electronic Signatures), the United Kingdom and most of Asia.
The blockchain anchor adds tamper-evident proof on top of the standard certificate of completion. If a client later claims you altered the deliverables or scope after signing, you have independently verifiable evidence that the file is identical to the one signed.
Legally binding online contract tools for freelancers should cover three things: a signature that holds up in court (ESIGN / eIDAS AES), an audit trail you can produce on demand, and payment collection so the contract and the invoice are tied together.
Chaindoc covers all three on its free and low-cost tiers — most competitors gate at least one behind enterprise pricing. The blockchain audit trail is the extra layer that makes evidence verifiable without trusting either party, which matters when a client disputes scope or payment months later.
When you upload a document, it receives a unique blockchain hash and is recorded in an immutable registry. This confirms authorship, stores the complete history of changes, and serves as verifiable evidence in payment disputes or IP ownership questions.
Yes. Documents are signed with a legally binding digital e-signature. Your client receives a signing link, signs in a few clicks from any device, and you see the status immediately. A certificate of completion is generated automatically for your records.
Chaindoc saves every version automatically and shows exactly who made each change. You can compare versions, leave a comment, and revert to any previous state at any time. Nothing gets lost and nothing can be disputed without a clear record.
Yes. Access rights are configured per participant — view, edit, or sign. Comments and notifications update in real time, so everyone stays aligned without separate email threads or version confusion.
Yes. Documents are accessible online around the clock, so clients in any country can review and sign. Chaindoc's e-signatures are legally valid under the ESIGN Act (US), eIDAS (EU), and equivalent laws in the UK and other major jurisdictions. Payments are accepted in multiple currencies. Freelancers who refer clients regularly can also join the partner program and earn commissions.
