As of 1 November at 07:52 UTCUTC, the Mark Method for TIAUSDTZ23 was changed to Fair Price marking.
This was possible, as we have now constructed a robust index that represents the spot prices of TIA.
TIA is now priced on the .BTIAT index which incorporates TIA prices from Binance, Bybit, Gate.io and KuCoin..
Please note that this also means that Limit Down and Limit Up price protections have been removed.
