FRAME: Meta Transaction

[muharem]

Meta transactions implementation.

The meta transaction follows a layout similar to that of a regular transaction and can leverage the same extensions implementing the TransactionExtension trait. Once signed and shared by the signer, the relayer may submit a regular transaction with the pallet_meta_tx::dispatch call, passing the signed meta transaction as an argument.

To see an example, refer to the mock setup and the sign_and_execute_meta_tx test case in substrate/frame/meta-tx/src/tests.rs file.

RFC: #4123

I think we no longer need to copy types like this. We can get rid of RuntimeCall and RuntimeOrigin associated types here and directly bound the frame system config supertrait:

pub trait Config: frame_system::Config<
    RuntimeCall: Parameter
			+ GetDispatchInfo
			+ Dispatchable<
				Info = DispatchInfo,
				PostInfo = PostDispatchInfo,
				RuntimeOrigin = <Self as Config>::RuntimeOrigin,
			>,
    RuntimeOrigin: AsTransactionAuthorizedOrigin
			+ From<SystemOrigin<Self::AccountId>>
>
{
...
}

[muharem]

these types of bounds are unstable, CI jobs failing, I left them unchanged for now

[gui1117]

It should be stable since June :-/ https://blog.rust-lang.org/2024/06/13/Rust-1.79.0.html

[gui1117]

Was there a particular CI jobs failing? I will try to fix it.

For now it seems somewhat green: #6817
