Currently, users can register address at ENS/Unstoppable to create a “verified” user name associated with a wallet.
However, a user can also create its own username potentially “stealing” a username registered on ENS/Unstoppable.
Would it be possible to Moralis to forbid existing and verified username on ENS/Unstoppable?
This way we would allow both decentralization and free usernames (but unverified).
The following implement this for ENS. For unstoppable domain, I am struggling to get a good reverse lookup.
const fetchENSDomain = async () => {
const ethers = Moralis.web3Library;
const cloud_provider = new ethers.providers.CloudflareProvider()
var address = await cloud_provider.resolveName(username)
return address
};
const changeUsername = async () => {
const foundaddress = await fetchENSDomain()
if (foundaddress===null || foundaddress.toLowerCase() === user.get('ethAddress')) {
user.set("username", username)
try {
await user.save()
return true
} catch (error) {
alert("Error: " + error.code + " " + error.message)
return false
}
} else {
alert("This username is registered in Ethereum Name Service")
}
}
