Know They Own It.
Your customers sign a message with their wallet. We verify the signature. You get a PDF you can actually show an auditor. Done in under a minute.
For lenders, brokers, and compliance teams.
You're emailing customers for screenshots. They're sending edited images. You're forwarding threads to compliance. And when the auditor asks, you're digging through folders. Sound familiar?
