Address Registry

AddressRegistry.sol: A contract for managing contract addresses and whitelist state, enabling address storage, de-whitelisting, bulk whitelist updates, and verification of whitelist status for borrowe

Summary:

AddressRegistry.sol is a contract that stores addresses of other contracts and controls the whitelist state. It also provides the ability to de-whitelist contracts or tokens, which is an important security feature in case of vulnerabilities or forks.

Key Features:

• Stores addresses of other contracts and controls whitelist state.

• Supports de-whitelisting to prevent further borrowing with specific tokens or contracts.

• Allows for updating whitelist states for multiple addresses at once.

• Provides functions to check the whitelist status of borrowers and tokens.

• Keeps track of registered lender vault addresses.

Key Functions:

• initialize(): Initializes the AddressRegistry contract with the addresses of the lenderVaultFactory, borrowerGateway, and quoteHandler contracts.

• setWhitelistState(): Sets the whitelist state for multiple addresses, allowing them to be whitelisted, compartmentalized, or not whitelisted.

• setWhitelistedTokensForCompartment(): Whitelists or de-whitelists tokens for a given compartment.

• setMysoTokenManager(): Updates the MYSO token manager address.

• addLenderVault(): Registers a lender vault address in the AddressRegistry.

• claimBorrowerWhitelistStatus(): Allows borrowers to claim their whitelist status until a specific time by providing a valid signature.

• updateBorrowerWhitelist(): Updates the whitelist status for multiple borrowers.

• isWhitelistedBorrower(): Checks if a borrower is currently whitelisted by a specific authority.

• isWhitelistedCompartment(): Checks if a token is whitelisted for a given compartment.

• registeredVaults(): Returns an array of registered lender vault addresses.

Libraries:

• ECDSA: The contract imports the ECDSA library from the OpenZeppelin library for ECDSA signature verification.

Interfaces:

• IAddressRegistry: The contract imports the IAddressRegistry interface, which defines the owner function that needs to be implemented by the AddressRegistry contract.

Inheritance:

• Ownable: The contract inherits from the Ownable contract, which provides a modifier for owner-based access control.

Dependencies:

• DataTypesPeerToPeer: The contract imports the DataTypesPeerToPeer contract to access the WhitelistState enum used for whitelist management.

• Errors: The contract imports the Errors library, which provides custom error messages for different exceptional scenarios.
