We've always maintained that NFTs are going to be one of the foundational technologies of Web3, with use cases that go far beyond digital art and gaming. Clet, a SKALE-native service that maps a unique, human-readable name and other user data to your Ethereum address and stores it as an NFT, is a great example of that.
We have now integrated Clet into Ruby's UI. If you have a Clet name, you'll now see it displayed instead of your Ethereum address when viewing your gems and account history in the Profile section.
What Is Clet?
Clet (the name comes from Crypto walLET) is a Web3 naming system that allows users to map their Ethereum address—essentially a random string of characters—to a simple, memorable name, much like popular services such as ENS and Unstoppable Domains, which are built on Ethereum mainnet. These blockchain-based solutions are similar to the way that IP addresses are resolved to human-readable website addresses by the Domain Name System (DNS).
Because Clet is built on SKALE as well as Ethereum L1, it includes the ability to attach lots of useful arbitrary data to the blockchain record—including a PFP, crypto addresses, personal/business website, and social media accounts—without any gas costs for the user. Aside from the initial purchase of the domain name, all of this, and any updates you may make in the future, are completely free, making it more flexible and powerful than mainnet-only solutions.
How To Use Clet
Clet has recently released its V2 upgrade, providing more options and a better UX for users. To use Clet, first download the browser extension.
To buy a Clet name, you'll need some mainnet ETH. Check for available names using the search box.
If your chosen name is free, you'll be able to purchase it for a relatively low price (as with ENS, shorter names cost more, though are not prohibitively expensive).
Once you've bought your Clet name, you can attach information to it. First and foremost, add your Ethereum address, so that supported dApps on other chains can display your Clet name when you are connected to them. (Your name will still be shown on the native Calypso chain without this step.) But you can also add all kinds of other useful data, including different crypto wallets, a profile image, personal details, social media accounts, and more.
Thanks to SKALE's zero-gas architecture, all the information you map to your Clet name is free.
Once you've mapped a name and PFP to your Clet record, set it as your default name (you can own many Clet names, so one needs to be the default record for your address). Your name and picture will be displayed at the top right of the Clet website. You'll also see your user name on Ruby's profile page, and any other SKALEVERSE apps that support Clet!
