If you are only interested in trading Ethereum tokens on Saturn Network then you do have several options you can use as a compatible dApp browser such as MetaMask or our own Saturn Wallet. What about if you would like to continue buying & selling Ethereum tokens while you are on the go? We have developed Saturn Network exchange to be entirely mobile friendly, but, browser extensions never work very well on mobile(in most cases they do not work at all!) which is why if you want to keep the same user-friendly experience you have on your desktop or laptop using MetaMask or Saturn Wallet is not an option.
