* Our friendship is expressed through a range of technical capabilities, including the innovative **mirroring technique**. Hellobot, our flagship NFT, transcends the limitations of individual chains, establishing friendships with every chain through mirroring technology.
* As the only NFT to exist in all chains, Hellobot's pioneering status is exemplified in its debut on **the Polygon chain**. While all minting and secondary transactions occur on ETH, our mirroring technology ensures that Ethereum chain transactions are mirrored seamlessly onto Polygon. (For more technical details, please refer to the Medium article that will be published later.)
* Mirroring with other chains will also be added in the future.
