🆒ZNSAddressResolver

The specific Resolver for ZNS that maps domain hashes to Ethereum addresses these domains were made for.

This Resolver supports ONLY the address type. Every domain in ZNS made for a contract or wallet address will have a corresponding record in this Resolver.

domainAddresses

mapping(bytes32 => address) domainAddresses

Mapping of domain hash to address used to bind domains to Ethereum wallets or contracts registered in ZNS.

constructor

constructor() public

initialize

function initialize(address accessController_, address registry_) external

Initializer for the ZNSAddressResolver proxy. Note that setter functions are used instead of direct state variable assignments to use access control at deploy time. Only ADMIN can call this function.

Parameters

Name	Type	Description
accessController_	address	The address of the ZNSAccessController contract
registry_	address	The address of the ZNSRegistry contract

resolveDomainAddress

function resolveDomainAddress(bytes32 domainHash) external view returns (address)

Returns address associated with a given domain name hash.

Parameters

Name	Type	Description
domainHash	bytes32	The identifying hash of a domain's name

setAddress

function setAddress(bytes32 domainHash, address newAddress) external

Sets the address for a domain name hash. This function can only be called by the owner, operator of the domain OR by the ZNSRootRegistrar.sol as a part of the Register flow. Emits an AddressSet event.

Parameters

Name	Type	Description
domainHash	bytes32	The identifying hash of a domain's name
newAddress	address	The new address to map the domain to

supportsInterface

function supportsInterface(bytes4 interfaceId) public view virtual returns (bool)

ERC-165 check for implementation identifier Supports interfaces IZNSAddressResolver and IERC165

Parameters

Name	Type	Description
interfaceId	bytes4	ID to check, XOR of the first 4 bytes of each function signature

getInterfaceId

function getInterfaceId() public pure returns (bytes4)

Exposes IZNSAddressResolver interfaceId

setRegistry

function setRegistry(address _registry) public

Sets the address of the ZNSRegistry contract that holds all crucial data for every domain in the system. This function can only be called by the ADMIN. Emits a RegistrySet event.

Parameters

Name	Type	Description
_registry	address	The address of the ZNSRegistry contract

_authorizeUpgrade

function _authorizeUpgrade(address newImplementation) internal view

To use UUPS proxy we override this function and revert if msg.sender isn't authorized

Parameters

Name	Type	Description
newImplementation	address	The implementation contract to upgrade to
