Edge

Edge is a San Diego company building a self-custody, privacy-first mobile wallet for buying, storing, swapping and spending more than 120 cryptocurrencies. Founded in 2014 as Airbitz and rebranded to Edge in 2018, it pioneered a username-and-password login model backed by client-side encryption and a zero-knowledge architecture, so private keys and account data never leave a user's device unencrypted. The same security layer is offered to developers as the Edge Login SDK.
