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.
Paul Puey is the CEO and co-founder of Edge, a San Diego-based self-custody crypto wallet and security platform. A UC Berkeley electrical engineering and computer science graduate who once shipped 3D graphics at Nvidia, he caught the Bitcoin bug in 2013 and launched Airbitz in 2014, rebranding it to Edge in 2017 as crypto moved beyond Bitcoin. His pitch is stubbornly simple: if you do not hold your keys, you do not own your coins, and security belongs on the edges of the network, in your hands, not on someone else's server.
