FAQ

Questions teams ask before switching to Chaindoc

If you're moving from DocuSign, PandaDoc, or another e-signature tool — these answer the common ones.

Chaindoc is an agreement management platform. You sign contracts, verify identity with built-in KYC, and collect payments — without bouncing between three tools.

It fits SMBs and mid-market teams that handle real contracts: real estate, healthcare, insurance, fintech, IT services. The whole loop — draft, sign, verify, pay — runs from one workspace.

Chaindoc bundles e-signature, KYC, and payments in one workflow. DocuSign, PandaDoc, and Adobe Sign require separate tools for identity verification and payment collection.

Side-by-side: DocuSign, PandaDoc, Adobe Sign, HelloSign.

Zero migration fee. Import your templates as PDFs, set up signing flows in the dashboard, invite your team. Most teams switch in under an hour.

See pricing for what you'd pay on Chaindoc — typically a fraction of per-seat plans on DocuSign or Adobe.

Upload a PDF or pick a template. Drop in signature fields. Add signers, set roles, send. Every step is logged — who signed, when, from where, with what verified identity.

The signed document lands back in your dashboard with a SHA-256 hash on the blockchain. Anyone can verify it — including the courts.

Yes. KYC is built into the signing flow — signer uploads ID, we verify, then they sign. No separate KYC vendor, no tab-switching.

You can require identity verification before anyone signs. Useful for financial agreements, real estate deals, anything where you need to know who's actually on the other end.

The verification result is attached to the signed document. When someone asks "did you check their identity?" — you have a record, not a memory.

Contract gets signed, payment triggers. No separate invoice, no "please pay within 30 days" email.

Each payment ties to a specific agreement — amount, terms, due date visible to both sides. Works for one-time deals, recurring arrangements, and milestone payouts. Powered by Stripe.

Payment status lives next to the contract — see what's signed and what's paid without checking two systems.

End-to-end encryption on every document. Blockchain audit trail on every signature — cryptographically sealed and timestamped. Edits, views, signature events all logged immutably.

eIDAS-, ESIGN Act-, and UETA-compliant. ISO 27001 and CSA STAR certified. The security stack is audited by third parties — not just described in marketing copy.

Yes. E-signatures in Chaindoc are PAdES-BES Advanced Electronic Signatures (AES) under eIDAS Article 26, valid under ESIGN Act (US) and UETA. Contracts signed here are enforceable in the EU, US, UK, and most jurisdictions that accept electronic signatures.

Certifications: ISO 27001, ISO 9001, CSA STAR. Each signature gets a blockchain audit trail — the kind of record that holds up when someone asks for proof.

Each signed document gets a record: who signed, when, their verified identity, the SHA-256 document hash, and the blockchain transaction ID.

Anyone can check whether the document was altered since signing — compare the hash, done. The record sits on a blockchain, so it can't be edited after the fact. Not by the other party, not by Chaindoc, not by anyone.

Healthcare, finance, insurance, real estate teams use this when they need to prove exactly what was signed and that nothing changed afterward.

Yes. Chaindoc supports technical docs, product specs, internal knowledge bases, and API documentation alongside contracts.

Updates are tracked — teams can always see how content has changed. This fits teams that treat documentation as a long-term asset, where reliability and history matter.

Yes. Chaindoc connects to your stack via REST APIs and webhooks. CRMs, billing platforms, in-house tools — drop Chaindoc into your existing workflow.

Automate document generation, signing flows, agreement tracking. Same security and audit guarantees, embedded in your systems.
