Name Wrapper

Source
The Name Wrapper is a new contract for PNS that allows you to "wrap" any PNS name into a ERC-1155 NFT.
Before the Name Wrapper, only .pls 2LDs (second-level domains, like pns.pls) had ERC-721 NFTs associated with them, unless the owner created a separate custom contract.
With this new contract, you can wrap:
  • Any .pls name or subname
    • Examples: name.pls, sub.name.pls
  • Any DNS name or subname
    • Examples: name.com, sub.name.com
Unwrapped .pls 2LDs have the concept of a separate Owner (Registrant) and Manager (Controller). This changes after you wrap the name, because there is only a single account that serves as both the Owner and Manager for the wrapped name.

Deployed NameWrapper addresses

Wrapping and Unwrapping

When wrapping a .pls 2LD, you transfer the Owner (Registrant) of the ERC-721 NFT to the Name Wrapper contract. The contract will then automatically take over the Manager (Controller) for the name as well. You can do this by calling the wrapETH2LD method. Or, you can directly transfer the ERC-721 NFT to the Name Wrapper contract. In return, the contract issues you an ERC-1155 NFT.
When wrapping any other PNS name, you transfer the Manager (Controller) of the name to the Name Wrapper contract. You can do this by calling the wrap method. In return, the contract issues you an ERC-1155 NFT.
As the owner of the wrapped name, you can unwrap at any time by calling either unwrapETH2LD or unwrap. You can do this as long as the permission to unwrap has not been revoked.
