Hey there, you have an interesting project here however I'm bothered by this;
Just connect your wallets, set the desired amount, hit the Swap button and wait for Jelly to do all the work, then withdraw.
Obviously, linking the wallets to decentralized exchange site could be risky for user since it could be vulnerable when someone hack your site or have some bugs.
By the way, is your project is still on beta? I saw only eth and tron is currently available for swapping.
