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");
    _;
}

Parameters

Name	Type	Description
`from`	`address`	The address to check.

`mintable`

Restricts the function to ensure the recipient is not a blocked address.

modifier mintable(address to) {
    require(!COSMOS_CONTRACT.is_blocked_address(to), "ERC20: mint to blocked address");
    _;
}

Parameters

Name	Type	Description
`to`	`address`	The address to check.

`transferable`

Restricts the function to ensure the recipient is not a blocked address.

modifier transferable(address to) {
    require(!COSMOS_CONTRACT.is_blocked_address(to), "ERC20: transfer to blocked address");
    _;
}
