Custom ERC20 Functions
Once you created your token it is automatically registered as ERC20 token and you can use it like any other ERC20 token, with functions like
transfer
, balanceOf
, etc. But, as the ERC20 token maps the native token on L2, there are some additional ISC features
you can take advantage of.
Example Code
Get Your nativeTokenID
You can use the erc20NativeTokensAddress
function and the Foundry serial number to get the contract address:
ERC20NativeTokens token = ERC20NativeTokens(
ISC.sandbox.erc20NativeTokensAddress(_foundrySN)
);
nativeTokenID
will give you the native token ID of the ERC20 token:
NativeTokenID memory id =token.nativeTokenID();
Full Example Code
function nativeTokenID(uint32 _foundrySN) public view returns (bytes memory) {
ERC20NativeTokens token = ERC20NativeTokens(
ISC.sandbox.erc20NativeTokensAddress(_foundrySN)
);
NativeTokenID memory id =token.nativeTokenID();
return id.data;
}
