IZNSFixedPricer.sol Below is the doc for PriceConfig struct.

Struct for price configurations per domainHash that is used in the priceConfigs mapping

  • price The value determining how much a subdomain under a particular parent would cost

  • feePercentage The value determining how much fee is charged for a subdomain registration

Please note that the feePercentage is set in the basis of 10,000 where 1% = 100 and feePercentage is NOT being read when used with PaymentType.DIRECT. This value is only used when PaymentType.STAKE is set in ZNSSubRegistrar.

PriceSet

event PriceSet(bytes32 domainHash, uint256 newPrice)

Emitted when the PriceConfig.price is set in state for a specific domainHash

Parameters

NameTypeDescription

domainHash

bytes32

The hash of the domain who sets the price for subdomains

newPrice

uint256

The new price value set

FeePercentageSet

event FeePercentageSet(bytes32 domainHash, uint256 feePercentage)

Emitted when the PriceConfig.feePercentage is set in state for a specific domainHash

Parameters

NameTypeDescription

domainHash

bytes32

The hash of the domain who sets the feePercentage for subdomains

feePercentage

uint256

The new feePercentage value set

PriceConfig

struct PriceConfig {
  uint256 price;
  uint256 feePercentage;
  bool isSet;
}

initialize

function initialize(address _accessController, address _registry) external

setPrice

function setPrice(bytes32 domainHash, uint256 _price) external

getPrice

function getPrice(bytes32 parentHash, string label, bool skipValidityCheck) external view returns (uint256)

parentHash param is here to allow pricer contracts to have different price configs for different subdomains skipValidityCheck param is added to provide proper revert when the user is calling this to find out the price of a domain that is not valid. But in Registrar contracts we want to do this explicitly and before we get the price to have lower tx cost for reverted tx. So Registrars will pass this bool as "true" to not repeat the validity check. Note that if calling this function directly to find out the price, a user should always pass "false" as skipValidityCheck param, otherwise, the price will be returned for an invalid label that is not possible to register.

setFeePercentage

function setFeePercentage(bytes32 domainHash, uint256 feePercentage) external

getFeeForPrice

function getFeeForPrice(bytes32 parentHash, uint256 price) external view returns (uint256)

Returns the fee for a given price.

Fees are only supported for PaymentType.STAKE !

getPriceAndFee

function getPriceAndFee(bytes32 parentHash, string label, bool skipValidityCheck) external view returns (uint256 price, uint256 fee)

Fees are only supported for PaymentType.STAKE ! This function will NOT be called if PaymentType != PaymentType.STAKE Instead getPrice() will be called.

setPriceConfig

function setPriceConfig(bytes32 domainHash, struct IZNSFixedPricer.PriceConfig priceConfig) external

setRegistry

function setRegistry(address registry_) external
