Could you elaborate on the similarities and differences between PulseX and Uniswap? I've heard PulseX being discussed in the crypto community but I'm unsure if it operates similarly to Uniswap, which is a widely known decentralized exchange. Do they both facilitate token swaps? Does PulseX offer additional features or functionalities that Uniswap lacks? Is there a significant difference in their performance, security, or user experience? Clarifying these points would help me understand how PulseX stands out, if at all, compared to Uniswap.
