How Chaindoc speeds up real estate transactions
Paper contracts delay closings. Chaindoc removes that bottleneck — get documents signed, track every change, and collect payment without printing or couriering anything.
Paper contracts no longer delay closings. Send any real estate document for e-signature and get notified when each party signs. If someone hasn't signed by tomorrow, the system already reminded them.
Every transaction gets a blockchain record with a cryptographic hash, authorship data, and timestamp. Nobody can alter a signed document without it showing — which means you can prove exactly what was agreed to anyone who needs to see it.
Every edit creates a new version. If a buyer and seller negotiate terms across multiple drafts, the full change history is logged next to the document — showing who changed what, and when each version was agreed.
Accept a deposit or full payment immediately after signing, via Stripe or cryptocurrency. No manual payment tracking — confirmation is automatically added to the contract record.
Agents, lawyers, developers, and clients all work on the same document. You control who can view, edit, comment, or sign. No one misses their turn — the platform tracks approvals and sends reminders automatically.

Common questions from real estate teams about Chaindoc
Answers on closings, lease signing, disclosures, and blockchain audit trails for real estate. More at our support page.
Yes. Signatures from Chaindoc are legally binding. Each signatory gets a digital certificate, and the document gets a blockchain hash that ties everything together. Courts and financial institutions in most countries accept these — they comply with ESIGN, UETA, and eIDAS.
Every document gets a blockchain record with a cryptographic hash, authorship data, and timestamp. Any change to the file after signing breaks that hash — making tampering immediately detectable. The proof is built into the document itself, not stored somewhere that could be questioned later.
Chaindoc integrates payment directly into the document workflow. Once all parties sign, the buyer pays a deposit or the full amount via Stripe or cryptocurrency through the platform. Payment confirmation is automatically logged in the contract history — no manual reconciliation needed.
Yes. Chaindoc supports multi-party signing workflows. You define who needs to sign, in what order, and what access each person has. Agents, lawyers, buyers, sellers, and notaries can all participate in the same document. Everyone gets notified when it's their turn, and you see the full signature status in real time.
Documents are signed and paid for online regardless of where each party is located. Buyers and sellers in different countries complete the full signing process without meeting in person or mailing anything. You track signature status, access documents, and confirm payments all from the same dashboard.
Yes. Chaindoc stores the full history of every document — all versions, amendments, extension agreements, and signature events. For multi-year leases, you can track every change, see who updated what and when, and pull up the complete paper trail at any point.
