Keeper is a self-custody crypto wallet for multiple blockchains, available on iOS, Android, desktop, web, and as a browser extension.

The app supports buying and selling crypto with common payment methods, swapping between networks without bridges, staking, and sending to saved contacts. A fee balance called Battery lets users pay network fees with assets they already hold or a bank card instead of buying gas tokens first. A built-in browser connects to decentralized applications across the supported networks.
