They can be exchanged on any existing AMM (like Uniswap, Sushiswap etc), OTC portals, as well as centralized exchanges in the future considering they are ERC20s - giving exchanges instant adaptability for Dopex option tokens.

## Exercise & Settlements

All option expiries are at 8:00 AM UTC and can be exercised during a 1 hour window before the expiry time i.e between 7:00 AM UTC to 8:00 AM UTC.
Settlements on option exercises happen without requiring the underlying asset and hence are net settlements. The PnL (Profit & Loss) of the option is calculated and if it is +ve then the exercise can go through which burn the option tokens (doTokens) and transfer the PnL in the settlement asset to the user. PnL is calculated in the following manner:
For CALLs (settlement is done in the base asset):
$PnL = ((Price - Strike) * Amount) / Price$
For PUTs (settlement is done in the quote asset):
$PnL = (Strike - Price) * Amount$
Here Price is the current price of the asset and Amount is the amount of options being exercised.
The settlement fee (exercise fee) is deducted from the final PnL. To learn more about fees, visit the fees section.
