Blocknify API allows you to quickly add a legally compliant e-signature solution, built on smart contracts on the blockchain, to any web application. It's easy as a straightforward call.
Your users can sign via iframe, redirect to blocknify, or through an emailed invite. Email is required for users who haven't verified their email on your solution.
Emails can be customized with your logo and sent from your email address. We also support our web application to be customized with your logo and brand colors.

Advance example with existing document
Two signers want to be added. One is a logged-in user, and the other one is external (e.g., lawyer). Therefore, we want the logged-in user to sign the document via an iframe, and we want an invite email to go to the lawyer.
