hello! trading is currently disabled as of jan/feb of this year while Pearl Abyss is revamping everything. however, if you were wondering how trading USED to work, our ambassador Tansie made a wonderful guide that you could look at here. PLEASE keep in mind that trading is disabled at the moment so i don't recommend doing anything with this guide other than bookmarking it, as soon as the trading rework happens you can be sure Tansie will update this page to reflect whatever new content we receive.
