Edge (formerly Airbitz) is a self-custody cryptocurrency wallet focused on ease of use and security. Founded in 2014, the company rebranded from Airbitz to Edge in 2018 to reflect its expanded multi-currency support beyond Bitcoin.

Edge Wallet is available for iOS and Android and supports a wide range of cryptocurrencies including Bitcoin, Ethereum, Litecoin, Monero, XRP, and many ERC-20 tokens. The wallet features a familiar username/password login system while maintaining full self-custody — private keys are encrypted client-side and never stored on Edge's servers.

Key features include built-in exchange functionality (swap between supported cryptocurrencies within the app), support for buying crypto with fiat currency, and one-tap 2FA. The wallet uses client-side encryption with zero-knowledge architecture, meaning Edge cannot access user funds or data. Automatic encrypted backups ensure users can recover their wallets on any device.

Edge is headquartered in San Diego, California and is led by CEO Paul Puey.
