 You also have the option to inherit from the [InterchainTokenStandard](https://github.com/axelarnetwork/interchain-token-service/blob/main/contracts/interchain-token/InterchainTokenStandard.sol#L12) so that your token has cross-chain functionality built-in, such as the `interchainTransfer()` function.

-An Interchain Token is an ERC20 that is connected to [ITS](https://github.com/axelarnetwork/interchain-token-service/blob/main/contracts/InterchainTokenService.sol) upon deployment comes built-in with the `interchainTransfer()` function, which allows users to bridge their token between any blockchain to which it is deployed.
