Chain of events:
- FTX rebranded Pax to USDP on their deposit page, but they failed to notify users for the update.
- USDP is also ticker used by Unit protocol's stable coin.
- One FTX user assumed that exchange supports the Unit Protocol's stable coin - USDP, and he deposited the same (which in reality is not supported by the exchange but is erc20 token so ends up in exchange's address).
- He contacts the FTX support, they refund the amount but with 15% fee which amounts to around $1M.
- User was disappointed with the fee taken and appeals further but gets no response. Just cause,
TnC,
Wrong Address or Chain
FTX is not responsible if you send deposits or withdrawals to an incorrect address. If you are withdrawing from FTX to an incorrect address, there is nothing FTX can do to recover the tokens. If you deposit to an incorrect FTX address, we can attempt to recover it, but may charge a fee to do so, and if we do not generally support the deposited token or method we may be unable to recover it at all.
The chain that a crypto deposit is sent on is really important. If deposits are sent on the wrong chain we may attempt to recover it but this is in no way guaranteed. A minimum 5% fee will be charged but in many cases we will either not be able to recover the unsupported token or will require a significantly higher fee.
Looking at above tnc it says
minimum of 5%, so sounds like user is screwed but it has been updated 8 hrs ago.
The prior TnC was as follows (as taken for Rekt.News article),
FTX is not responsible if you send deposits or withdrawals to an incorrect address. If you are withdrawing from FTX to an incorrect address, there is nothing FTX can do to recover the tokens. If you deposit to an incorrect FTX address, we can attempt to recover it, but will charge up to $500 or 5% to do so.
The chain that a crypto deposit is sent on is really important. If deposits are sent on the wrong chain we will attempt to recover them but an automatic 5% fee will be charged for chains that we have systems to recover from; from other chains we might not be able to credit.
Here it says $500 or up to 5%.
