In this example, we will show how wBTC can be used for gas fee payment using the [ERC-4337 account abstraction standard](https://eips.ethereum.org/EIPS/eip-4337) on BOB Sepolia (Testnet). This enables users to use smart contract wallets and transact without the need to own ETH.

## Smart Contract wallets

This demo showcases wBTC transfer from the smart contract wallet. Smart contract wallets utilize smart contracts rather than single private keys found in Externally Owned Address (EOA) wallets. The programmable nature of smart contract wallets allows for diverse use cases. Unlike EOAs, smart contract wallets can contain logic but rely on EOAs to sign the user operations. Therefore, integration of the smart contract wallet into UI adds an additional complexity - users need to distinguish between the signer (EAO) and the account that holds assets (smart contract wallet).

#### Making a transfer

1. Input the amount you wish to send and the recipient's address into the form fields.
2. Click on 'Transfer'. This will require three interactions with MetaMask: first one will deposit small amount of ETH to the entry point contract so that you can sign the user operation that allows the paymaster contract to spend your wBTC. Then you will sign the approval user operation. Finally, you will sign the transfer user operation.
