The NFT Resolver is Intended to be used to resolve any subdomain for a specific ENS domain where a NFT collection has been deployed on Linea.
More precisely it is ID based, meaning the resolution of an address for a subdomain is determined by the ownership of the NFT's ID on the target NFT contract on Linea.
If you own an ENS domain that you want its subdomains to resolve depending on a NFT collection deployed on Linea, simply follow those steps:
1 - Get the DNS encoded name of your ENS name, you can use etherJs dnsEncode function to get it: https://docs.ethers.org/v6/api/hashing/#dnsEncode
For example for efrogs.eth, the DNS encoded name is 0x066566726f67730365746800
2 - Get the target NFT contract you want to use to resolve the subdomains depending on the NFT's owner addresses.
For example: 0x194395587d7b169e63eaf251e86b1892fa8f1960
3 - Get the slot in the target NFT contract that contains the owner addresses.

If you are using hardhat for your smart contract project, you can also use the plugin hardhat-storage-layout
For example for the Efrogs NFT contract the owners are stored in the slot 122.
4 - Go to the NFT resolver contract
5 - Click on Connect to Web3with the wallet that owns the chosen ENS name (Example efrogs.eth)
6 - Click on setTarget and add the parameters:
name: [DNS encoded name of your ENS name] (Example 0x066566726f67730365746800)
target: [NFT contract address on Linea] (Example 0x194395587d7b169e63eaf251e86b1892fa8f1960)
Click on write and approve the transaction.
7 - Click on setBaseNodeResolver and add the parameters:
name: [DNS encoded name of your ENS name] (Example 0x066566726f67730365746800)
resolverAddr: [The resolver you want to keep using for your base domain] (Example 0x231b0Ee14048e9dCcD1d247744d114a4EB5E8E63)
Click on write and approve the transaction.
8 - Click on setTargetAddrSlot and add the parameters:
name: [DNS encoded name of your ENS name] (Example 0x066566726f67730365746800)
slot: [The slot in the target NFT contract that contains the owner addresses] (Example 122)
Click on write and approve the transaction.
9 - Go the ENS app website
10 - Go to your ENS name profile page (Example: https://app.ens.domains/efrogs.eth)
11 - Go to the tab More (Example: https://app.ens.domains/efrogs.eth?tab=more)
12 - In the Resolver section at the bottom, click on Edit
13 - Click on Custom Resolver
14 - Add the NFT Resolver's address: 0x8210077e031302C41aCD7FccC38628CA1788A999
You'll get a warning but this is normal.
15 - Click on Update, Open Walletand approve the transaction.
Once all those steps are done you can start resolving subdomains of your ENS domain using the NFT IDs minted on Linea.
Run the following:
npm i
npm test
