You can also lookup your tx with our explorer and api.

API/Explorer

Requirements to be compatible with anyCall interfaces:

1. Sender Contract: Your sender contract needs to call the method anyCall on the official anyCall contract.

2. Receiver Contract: A method named anyExecute needs to exist on your _to contract address. This is needed because anyExec (Our deployed anyCall Contract) will call anyExecute on your receiver contract.

3. Your contract needs to be payable to allow refund of excess fees.

anyCall Interfaces

anyCall (Called by Dapps)

function anyCall( address _to, bytes calldata _data, uint256 _toChainID, uint256 _flags, bytes calldata )

The destination chain would call anyExecute function on the _to address with _data passed in the function. And you can customize what you do with such _data.

Parameters

Param	Type	Description
_to	address	The target contract to interact with on _toChainID
_data	bytes	The calldata supplied for the interaction with _to anyExecute will be run with this _data on the receiver contract you deployed.
_toChainID	uint256	The target chain id to interact with
_flags	uint256	How dapps are paying gas fee of tx execution: 0: Gas fee paid on source chain. Fallback not allowed. 2: Gas fee paid on destination chain. Fallback not allowed. 4: Gas fee paid on source chain. Allow fallback 6: Gas fee paid on destination chain. Allow fallback

anyExecute (This exact format needs to be implemented in your dapp, what would be called on the destination chain)

function anyExecute(bytes calldata data) external override onlyExecutor returns (bool success, bytes memory result)

Parameters

Param	Type	Description
data	bytes	The calldata supplied for the interaction with subsequent contracts
Returned Values
success	bool	The address to call on _fromChainID if the cross chain interaction fails
result	bytes	The originating chain id

AnyCallExecutor

As stated above, AnyCallExecutor will make the final execution to your destination contract as a sandbox.

The address of this executor contract is stored in the main anycall contract. It can be accessed with an interface function like below.

interface CallProxy{
 
    function executor() external view returns (address executor);
}

The executor should then be saved in your contract constructor

constructor(){
        anycallExecutor=CallProxy(anycallcontract).executor();
    }
