Not going off the article, but if you think that 100% of smart contracts are useless, I would like to know why the uniswap is useless in your mind. Its a decentralized exchange contract for trading tokens on ethereum

Decentralized exchanges are a dime a dozen and are basically ghost towns compared to the centralized exchanges.

but it can be used to trade currencies not offered by centralized exchanges, in a way where you dont have to hand over any funds to risk on a centralized exchange. is useful for me at least
