dYdX is a DEX just like Uniswap (UNI), but it has leveraged trading.
Leverage trading can be simply described as “increased trading results”. For example, you choose a leveraged trade of x10 (multiply ten) when the trading results show that we can make a profit of 50 baht, but since we use the leverage at x10, our profit has increased by 10 times to 500 baht.
However, leverage is a double-edged sword. The reason being, if you trade and lose, the result of the loss is also multiplied by 10. Therefore, leverage is a tool suitable only for traders who are experienced and able to take a high level of risk.
Another outstanding point of dYdX is its Layer 2 function, developed by StarkWare's zkSTARKS technology. Resulting in transactions that are made via dYdX, will be faster, have cheaper fees, and small orders can be sent easily.
