As of 19 January at 04:18 UTC, the Mark Method for MANTAUSDTF24 was changed to Fair Price marking.
This was possible, as we have now constructed a robust index that represents the spot prices of MANTA.
MANTA is now priced on the .BMANTAT index which incorporates MANTA prices from Binance, ByBit, and Gate.io.
Please note that this also means Limit Down and Limit Up price protections have been removed.
