Wallet protocol

Wallet protocol allows interaction with your funds without paying gas via account abstraction. Funds are stored on a smart contract, that provides control only to owner. The key here, is that funds can be sent to wallet address before it's creation - and then transferred anywhere, by paying for gas in that token.

Use case

Imagine that you want to receive some token, for example USDC, on a new network, like Polygon. You generate address, send tokens there, but then, you suddenly remember, that you need gas. You can't even swap your tokens for it, because it also requires gas.

Here wallet protocol comes into help. Before sending tokens to an address, you first generate wallet (without creation, just address), and receive funds at that address. Then you can perform any transaction by wallet and pay for gas fee with that token.s
