Sign anything

From a contract to an SMS, with Self you can biometrically sign anything straight from your phone.

Agree faster

Agreements are signed in a single action, there's no need to fill out documents, and the result is messaged direct to the parties.

Embed credentials

Details you used to have to fill in before signing can now be appended to a signed document as verifiable credentials.

Always know your Signatory

100% biometric signatures

We don't believe in risk-based identification. With every action gated by biometrics there's no need to tier your approach to contract security.

Minimise the user data you need to hold

Self can operate without you holding any personally identifiable information, making regulations like GDPR and CCPA someone elses problem.

Add verifiable credentials to a document

A single exchange with a user can carry a payload of identity, credentials and more. So you can verify not just the signature, but the address and identity of a signatory.

Clear, comprehensive documentation

Real world code examples, example apps you can run, a powerful sandbox and snippets to get you started.

It's an embedded SDK

We've started with some commonly used server side frameworks and support for both iOS and Android.

Beta Release Notes

Self Sandbox has been released in beta. Here is a quick look at some features and limitations specific to this release.

"The great promise of the early internet has been replaced with real risks. These risks are fundamentally a consequence of leaving a gap between humans and the technology they rely upon. As the web, and the platforms that have come to dominate the online landscape, have grown, so tiny gaps have become the attack vectors fraudsters exploit."
