InterchainTokenExpressExecutable

Abstract contract that defines an interface for executing express logic in the context of interchain token operations.

This contract extends InterchainTokenExecutable to provide express execution capabilities. It is intended to be inherited by contracts that implement express logic for interchain token actions. This contract will only be called by the interchain token service.

bytes32 EXPRESS_EXECUTE_SUCCESS

constructor

constructor(address interchainTokenService_) internal

Creates a new InterchainTokenExpressExecutable contract.

Parameters

Name	Type	Description
interchainTokenService_	address	The address of the interchain token service that will call this contract.

expressExecuteWithInterchainToken

function expressExecuteWithInterchainToken(bytes32 commandId, string sourceChain, bytes sourceAddress, bytes data, bytes32 tokenId, address token, uint256 amount) external virtual returns (bytes32)

Executes express logic in the context of an interchain token transfer.

Only callable by the interchain token service.

Parameters

Name	Type	Description
commandId	bytes32	The unique message id.
sourceChain	string	The source chain of the token transfer.
