I reviewed this project recently. At the time of upgrading the plan, i send the trx from the exchange and the minimum TRX the exchange allowed was more than the worth of 2$, so some extra TRX were sent. At the time of review, i did not claim my extra trx back to my Mixin Message wallet but later (after a day or so)  i tried to check if this process really works.

So here is my  experience. I got my TRX refund instantly. However i do not understand the role of EPC and how it can be a surety to avoid assets lost through Mixin Wallet ?


          


The whole procedure for a refund is mentioned here. https://help.mixpay.me/en/articles/7063792-how-to-get-a-refund
