As of 12 Jun at 04:45 UTC, the Mark Method for IOUSDTMZ24 was changed to Fair Price marking.
This was possible, as we have now constructed a robust index that represents the spot prices of IO.
IO is now priced on the .BIOT index which incorporates IO prices from Binance, Bybit, Gate.io, HTX and Kucoin.
Please note that this also means Limit Down and Limit Up price protections have been removed.
