TokenState¶
Description¶
An external state contract to hold ERC20 balances and allowances. This operates as an adjunct to ExternStateToken, so that important token information can persist while the token contract itself can be switched out to upgrade its functionality.

Variables¶
balanceOf¶
ERC20 balances, note that as a public variable, this synthesises an accessor which is itself ERC20 compliant, so balances can be queried by dApps directly from the state contract.
Type: mapping(address => uint) public
allowance¶
ERC20 allowances. Also generates an ERC20 accessor in the same way as the balanceOf member.
Type: mapping(address => mapping(address => uint)) public
