As a multi-chain browser, OKLink provides Linkkey with on-chain data services. Linkkey has added an OKLink on-chain data jump entry on its official website. When all users access Linkkey, they can view the details of the project's on-chain data by jumping to OKLink. Linkkey is a Polygon social domain name agreement officially sponsored by Polygon, which supports users to create social domain names and publish personal social NFTs. The core gameplay is "Create-to-Earn", and more than 100,000 people have registered so far.
