useSendCalls

Hook for sending calls to a smart account or EOA wallet.

This hook provides functionality to execute calls on a smart account using Account Abstraction, or fall back to regular EOA transactions when connected to an EOA wallet. It handles the complete flow of preparing, signing, and sending calls.

If using this hook with an ERC-20 paymaster in pre-operation mode with autoPermit, the contents of the permit will be hidden from the user. It is recommended to use the usePrepareCalls hook instead to manually handle the permit signature.
