ERC20ACL

GitHub: ERC20ACL

Overview

The ERC20ACL contract provides access control mechanisms for ERC20 token operations. It includes modifiers to restrict certain actions based on conditions such as whether an address is a module address or a blocked address.

Constants

CHAIN_ADDRESS

The address of the chain signer.

address constant CHAIN_ADDRESS = 0x0000000000000000000000000000000000000001;

Modifiers

onlyChain

Restricts the function so it can be called only by the chain signer.

modifier onlyChain() {
    require(msg.sender == CHAIN_ADDRESS, "ERC20: caller is not the chain");
    _;
}

burnable

Restricts the function to ensure the sender is not a module address.

modifier burnable(address from) {
    require(!COSMOS_CONTRACT.is_module_address(from), "ERC20: burn from module address");
    _;
}

}
