Batching (accountCreation +) addOwnerAddress(spendPermissions) + approve(user, protocol, ....) + (more...)

[evmKnows]

Hi there,

first and foremost thank you for fleshing out an AA native "Permit2"

Would be particularly interested if the AA / Spend-Permission architecture would allow a batch / zap style onboarding to AA + SpendPermissions contract + dApp,

and if it is generally recommended to compress user actions all-in-one (balance between convenient UX vs. establishing expectations of "signing long jsons" > users being overloaded with TypedData > reading them less > potentially getting rekt in the future)

would love to hear your thoughts.

Vaguely fleshed out snippet below:

        CoinbaseSmartWallet.Call[] memory calls = new CoinbaseSmartWallet.Call[](3);
        calls[0].target = address(account);
        calls[0].value = 0;
        calls[0].data = abi.encodeWithSignature("createAccount(bytes[],uint256)", allInitialOwners, 0);
        calls[1].target = address(account);
        calls[1].value = 0;
        calls[1].data = abi.encodeWithSignature("addOwnerAddress(address)", address(spendPermissions));
        calls[2].target = address(spendPermissions);
        calls[2].value = 0;
    	calls[2].data = abi.encodeWithSignature(
    		"approve((address,address,address,uint160,uint48,uint48,uint48,uint256,bytes))",
    		.....
		);
		.... perform more calls
		
        bytes memory prepareData = abi.encodeWithSignature("executeBatch((address,uint256,bytes)[])", calls);
