Is a signature really the finish line?
Most people saw EthSign as just a handy app for signing crypto contracts. But looking closer, it revealed a massive infrastructure gap. Once a contract was signed, it was "siloed"—trapped and unusable by other systems.
The real challenge emerged: How do you prove an agreement exists without revealing private details? This pressure shaped Sign Protocol. It moved beyond simple workflow to build a verifiable "evidence layer." Now, Sign aims for sovereign-grade infrastructure where proof can travel across institutions securely.
EthSign was not just a product; it was the proving ground. It taught us that institutions do not just need signatures—they need inspection-ready evidence that survives contact with other systems.
Are your agreements ready for that journey?
