Electronic signature for freelancers and agencies
Working with clients requires quick document approvals, legal protection, and a clear record of what was agreed. Chaindoc reduces risk at every stage.
Safe
Document ownership is registered on the blockchain automatically. Files are tamper-proof from the moment of upload.
Legally binding
Legally valid under ESIGN Act (US), eIDAS (EU), and equivalent laws. One click — court-admissible proof.
Collaborative
Comment on sections, approve changes, and manage versions with your client directly on the document. No email threads.
Fast
Send documents for signing in under a minute. Status tracking and automated reminders keep the process moving.
Freelance document tools for managing client work online
Create, approve, and sign documents with clients in one place. No meetings required, no version confusion.
Create documents
Upload or import files in any standard format — PDF, DOCX, images. Any document is ready to work with in seconds.
Version history
Every edit is saved automatically. Compare versions, see who made changes, and revert to any previous state if needed.
Collaboration
Leave comments on specific sections, tag collaborators, and resolve notes directly on the document. No separate messaging required.
Blockchain confirmation
Each document gets a unique blockchain hash that confirms authorship and detects any subsequent tampering — permanently.
Signature
Send for signing in one click. The client signs from any device and you see the status update immediately.
Accept payments
Collect payments at signing — deposits, full amounts, or installments. All transactions are blockchain-confirmed.
Less admin, more billable hours
Send proposals, contracts and invoices from one place — e-signature, payments and a blockchain audit trail keep every client deal moving without the back-and-forth.
