Ramper KMS Architecture

At Ramper, our mission is to make web3 accessible for the next billion users. To do so — we are reimagining the wallet sign-in experience. We believe everyone should be able to login & authenticate into blockchain applications seamlessly.
No seed phrases. No downloads. No passwords. It should be a single-click login experience.
To enable this experience, we have designed a key management system that enables seamless wallet sign-in operations at scale while guaranteeing the security of the private wallet keys. Our system is patent-pending, audited by CertiK, and undergoing SOC2 II.
