Managing Domains Using Contracts

This guide covers how to manage Unstoppable Domain records using contracts. This process requires using the Etherscan and Polygonscan user interface to write and execute contracts.

Step 1: Select a UNS Registry Smart Contract

The UNS Registry contract is where domain owners store their data and is a map of domain namehashes to key-value dictionaries of records. Choose one of the Unstoppable Registry smart contracts to interact with (either mainnet or testnet).

Step 2: Open the "Write as Proxy" Tab for the Registry Contract

Navigate to the Contract tab in either the Etherscan or Polygonscan page of the Registry contract:

Next, navigate to the Write as Proxy tab under the Contract tab section:

Step 3: Connect Your Web3 Wallet

Click on the Connect to Web3 button in the Write as Proxy tab and connect the wallet associated with the domain:

Step 4: Manage the Domain Records

Choose the set or setMany method from the Write as Proxy tab section. The set method allows you to update a single record, while the setMany method allows you to update multiple records simultaneously.

Next, add the records you want to manage to the keys and values fields as a single value for the set method or array of values for the setMany method.

Step 5: Generate the Namehash of the Domain

You can generate the namehash of a domain using any of the resolution libraries or CLI. You can also use online tools to calculate the namehash of the domain.

const {default: Resolution} = require('@unstoppabledomains/resolution');
const resolution = new Resolution();
let namehash = resolution.namehash("brad.crypto")

import com.unstoppabledomains.resolution.Resolution;

DomainResolution resolution = new Resolution();
String namehash = resolution.getNamehash("brad.crypto");

import UnstoppableDomainsResolution

guard let resolution = try? Resolution() else {
  print ("Init of Resolution instance with default parameters failed...")
  return
}

let namehash = try resolution.namehash(domain: "brad.crypto")

package main

import (
    "fmt"
    "github.com/unstoppabledomains/resolution-go"
)

func main() {
    uns, _ := resolution.NewUnsBuilder().Build()
    namehash, _ := uns.Namehash("brad.crypto")
    fmt.Println("The namehash for brad.crypto is", namehash)
}

$ resolution namehash -d brad.crypto
"0x756e4e998dbffd803c21d23b06cd855cdc7a4b57706c95964a37e24b47c10fc9"

After generating the domain namehash, insert it into the tokenId field of the set or setMany method.

Step 6: Execute the Contract

Click the Write button to sign the transaction and execute the contract:

After signing the transaction, you can view its details on the blockchain explorer, like so:
