IDRX

The contract provides an arbitrary account blacklisting feature, where a privileged role (holder of `BLACKLIST_ROLE`) can blacklist a user's account, and then destroy any funds held in the blacklisted account.

In the contract `IDRX` the priviledge roles have authority over the functions shown in the diagram below.  - `pause()`: Pauses all token transfer functionality. Only accessible to addresses with the `PAUSER_ROLE`. - `unpause()`: Unpauses the token transfer functionality. Only accessible to addresses with the `PAUSER_ROLE`. - `mint(address to, uint256 amount)`: Mints the specified amount of tokens to the specified address. Only accessible to addresses with the `MINTER_ROLE`. - `mintBridge(address to, uint256 amount, uint fromChain, uint fromChainBridgeNonce)`: Mints tokens and transfers them to a bridge after deducting a fee. Only accessible to addresses with the `MINTER_ROLE`. - `_authorizeUpgrade(address newImplementation)`: Authorizes a new implementation for the contract. Only accessible to addresses with the `UPGRADER_ROLE`. - `addBlackList(address _evilUser)`: Adds the specified address to the blacklist. Only accessible to addresses with the `BLACKLIST_ROLE`. - `removeBlackList(address _clearedUser)`: Removes the specified address from the blacklist. Only accessible to addresses with the `BLACKLIST_ROLE`. - `destroyBlackFunds(address _blackListedUser)`: Destroys the funds of a blacklisted address. Only accessible to addresses with the `BLACKLIST_ROLE`. - `setPlatformFeeInfo(address _platformFeeRecipient, uint64 _burnBridgeFee, uint64 _mintBridgeFee)`: Sets the platform fee recipient and the fees for burning and minting on the bridge. Only accessible to addresses with the `MINTER_ROLE`. Any compromise to the `_role` account may allow the hacker to take advantage of this authority and update the sensitive settings and execute sensitive functions of the project.

In the contract `IDRX`, the role `MINTER_ROLE` has the authority to update the token balance of an arbitrary account without sanity restriction. Any compromise to the `MINTER_ROLE` account may allow a hacker to take advantage of this authority and manipulate users' balances by calling `mint()` and/or `mintBridge()` functions

The privileged role has the authority to update the implementation contract behind the proxy contract. Any compromise to the privileged account may allow a hacker to take advantage of this authority and change the implementation contract which is pointed by proxy and therefore execute potential malicious functionality in the implementation contract.
