Contracts should implement this interface to accept express calls from the InterchainTokenService.
IMPORTANT: Express execute can be called by anyone willing to pay for the tokens upfront. This means the parameters passed to express execute are NOT validated by the GMP gateway. Only the token transfer itself should be considered to have value. The payload and any other metadata should NOT be used for anything critical beyond manipulating the received tokens.
function expressExecuteWithInterchainToken(bytes32 commandId, string sourceChain, bytes sourceAddress, bytes data, bytes32 tokenId, address token, uint256 amount) external returns (bytes32)
Executes express logic in the context of an interchain token transfer.
Only callable by the interchain token service.
| Name | Type | Description |
|---|---|---|
| commandId | bytes32 | The unique message id for the call. |
| sourceChain | string | The source chain of the token transfer. |
| sourceAddress | bytes | The source address of the token transfer. |
| data | bytes | The data associated with the token transfer. |
| tokenId | bytes32 | The token ID. |
| token | address | The token address. |
| amount | uint256 | The amount of tokens to be transferred. |
| Name | Type | Description |
|---|---|---|
| [0] | bytes32 | bytes32 Hash indicating success of the express execution. |
