Domain Deregistration

There are currently four public functions that can result in a domain being deregistered:

function popDomain(uint256 _tokenID) external

• If autoRenew is off and the domain is past its expiry date, popDomain can be called to delete the domain and refund the bond to its owner.

function collectDues(uint256 _tokenID) external

• If the domain has autoRenew set to true, you cannot use popDomain and must instead use collectDues.

• This function will use the domain's bond to top-up the domains' domainExpires timer.

• If the domain does not have sufficient bond to cover the top-up, the domain will be deleted and no refund will be offered to its owner.

function withdrawEarly(uint256 _tokenID) external

• Lets the owner of a domain deregister their domain and receive their bond back.

• Each year is paid in advanced, they will not receive a refund.

• This can help users receive their bond back after migrating.

function invalidateDomain(uint256 _tokenID) external

• If a user registers a domain that is too short, anyone can call this to delete their domain.

• The caller will be paid out a VET reward to incentivize active monitoring for invalid domains.
