A picture project on the mainnet, $UPEG, has become popular in the past two days. After looking at this project, it seems that after the V4 upgrade on the mainnet, developers are allowed to install a plugin called Hook on the transaction pool, which can automatically run a piece of custom code before and after a transaction. This project utilizes this mechanism to achieve on-chain innovation. Whenever you make a purchase in the V4 pool, the Hook will automatically generate a unique 24×24 pixel unicorn on the chain. Selling it destroys it, and the transaction becomes art. Trading is no longer just about exchanging money; it can also trigger extra fun events, turning cryptocurrency trading into a game that automatically generates on-chain pixel collectibles. The mechanism of $UPEG is essentially an on-chain dynamic ticket system. Traditional paper tickets: You pay for a ticket → You receive a voucher → The voucher proves you are eligible (to enter, collect, or resell). And $uPEG: You spend money to make a transaction → The system automatically generates an on-chain unicorn image for you → This image is your on-chain token. It perfectly combines DeFi trading with the acquisition of unique on-chain credentials, opening up a lot of possibilities for the future, such as event tickets, membership certificates, RWA credentials, etc.
