Technical Details

The protocol at launch comprises contracts: HLN_Minter, HLN_Router, HLN_RegistratorV1, HLN_Auction, and HyperliquidNames.

Standard Flow

1. Either an auction is initiated on the Auction contract, which calls to the HLN_Minter at auction close or the HLN_Minter is called via another issuance or sale mechanism.

2. The HLN_Minter contract verifies the relevant payment or permission properties and calls the HLN_Router to ask for the current Registrator version.

3. HLN_Router contract responds to calls for the currentVersion index with a corresponding Registrator address ( as of launch:HLN_RegistratorV1).

4. The HLN_Minter calls the given HLN_RegistratorV1 , which in turn creates a new name and issues a corresponding token via the HyperliquidNames to the new ownership.

EOA Permissions Assumptions

• Deployer: has the highest level of permission for each contract. This party set the initial state of the protocol, specifying the version of the HLN_RegistratorV1 contract and the signer for the HLN_Minter contract.

• Signer: a specific address, whose corresponding private key has sole authorization to sign minting calls. This ensures minting can only occurr through the authorized dApp and not direct on contract, which would allow bypassing name validation (normalization and whitelist).

• NameOwner: The owner of a name has the ability to transfer the token or renew (extend) the name expiry. They can also set primary and subdomain controllers for the name.

• Controller: The controller of the primary or subdomain name have the ability to set resolution addresses and Text Records for their corresponding level.
