Simple, Secure E-Signatures & API
Sign PDFs, prepare contracts, and collect signatures in seconds. Fast, affordable, and built for modern teams.
Reusable Document Templates & Custom Fields

Stop re-building contract layouts manually. Save your standard document structures as active Zign templates and auto-populate signee data on demand.
Contact Management & Team Address Book
Centralized directory for frequent signers and organization contacts:
- Store client emails, signee roles, and company affiliations in one vault
- Share contact address books across your team to speed up signature dispatch
- Track active signature envelope history by recipient contact
Now the Zign address book icon is always accessible. The contact directory lets you instantly autofill signee details for any document recipient.
Alex Chen — LegalTamper-Evident Audit Trail & Stored Info
Cryptographic security checksums and timestamped chain of custody:
- Complete audit trail certificates generated and stored for every executed document
- Tracks IP addresses, signee browser user-agents, device info, and timestamp logs
- Cryptographic SHA checksum verification prevents unauthorized contract modification
Every signed contract generates a tamper-evident audit trail certificate detailing complete signer authentication, timestamps, and integrity verification.
