PulseX is a DEX that is used on the PulseChain Network. If you want to take full advantage of the PulseChain ecosystem then you will want to consider bridging your ETH over to the PulseChain network.

Bridging is super simple and the software is provided so you can run the bridge on your own PC. Not trusting a middleman to run the bridge or the DEX is what I enjoy about this network.
