Bophades policy to handling minting and burning of OHM using Chainlink CCIP on non-canonical chains

As the CCIP contracts have a minimum solidity version of 0.8.24, this policy is also compiled with 0.8.24 Despite being a policy, the admin functions inherited from TokenPool are not virtual and cannot be overriden, and so remain gated to the owner.

State Variables

MINTR

Bophades module for minting and burning OHM

MINTRv1 public MINTR;

_typeAndVersion

Unique identifier for the TokenPool

This is used to identify the TokenPool to CCIP

string internal constant _typeAndVersion = "BurnMintTokenPool 1.5.1";

Functions

constructor

constructor(address kernel_, address ohm_, address rmnProxy_, address ccipRouter_)
    Policy(Kernel(kernel_))
    TokenPool(IERC20(ohm_), 9, new address[](0), rmnProxy_, ccipRouter_);

configureDependencies

Define module dependencies for this policy.

function configureDependencies() external override returns (Keycode[] memory dependencies);

Returns

Name	Type	Description
dependencies	Keycode[]	- Keycode array of module dependencies.

requestPermissions

Function called by kernel to set module function permissions.

function requestPermissions() external view override returns (Permissions[] memory permissions);

Returns

Name	Type	Description
permissions	Permissions[]	requests - Array of keycodes and function selectors for requested permissions.

VERSION

Returns the version of the policy

function VERSION() external pure returns (uint8 major, uint8 minor);

Returns

Name	Type	Description
major	uint8	The major version of the policy
minor	uint8	The minor version of the policy

_burn

Burns the specified amount of OHM

Implementation of the _burn function from the BurnMintTokenPoolAbstract contract

function _burn(uint256 amount_) internal override onlyEnabled;

_mint

Mints the specified amount of OHM

Implementation of the _mint function from the BurnMintTokenPoolBase contract

function _mint(address receiver_, uint256 amount_) internal override onlyEnabled;

getBridgedSupply

Returns the amount of OHM that has been bridged from mainnet

This function is not used in this policy, so it returns 0

function getBridgedSupply() external pure returns (uint256);

typeAndVersion

function typeAndVersion() external pure override returns (string memory);

supportsInterface

function supportsInterface(bytes4 interfaceId) public pure override returns (bool);
