Key Features

Cryptographic signature layers

For each signed document, there are 2 cryptographic signature layers to enforce security: a digital signature on the document related to the user and a digital signature related to the organisation (as in Web2 solutions.)

Document Referencing

Document referencing on blockchain to immutably log the content (in an obfuscated manner) and signature.

Verification

Independent document and signature verification vs on-chain reference, by validating that the document hash matches the hash on the blockchain.

Sequential or custom signature orders

Sequential or custom signature orders and recipient roles are beneficial when multiple signees, and authorisers are required.

Specific Field Placement

The signature requestor can specify areas on the document where the visual signatures and other inputs (like date, initials, custom text) must be placed, creating an intuitive user experience, in line with traditional methods of signature.

Friendly dashboard interface

Friendly dashboard interface for easy document management, status overview and tracking document trails.

Magic Link signing

Magic Link signing to support streamlined and user friendly but low security signing.

Scheduled sending of envelopes

Schedule sending envelopes to a later date.

Reminders

Send reminders to recipients that haven't signed yet.

Envelope Audit Trails

Comprehensive, tamper-evident logs with detailed timestamps and signer info
