The DVM should support the addition of vBNTBNT as a supported price ID. The use of this price identifier will primarily be for call options. This UMIP will also outline how to calculate the price of vBNT in BNT using a custom script that will be used for the call option price calculation.
This UMIP can also be extended to creating a price feed for vBNTBNT.

# Summary
The DVM should support the addition of vBNTBNT as a supported price ID. The use of this price identifier will primarily be for call options. This UMIP will also outline how to calculate the price of vBNT in BNT using a custom script that will be used for the call option price calculation.
This UMIP can also be extended to creating a price feed for vBNTBNT.
# Motivation
The DVM currently does not yet support the required price identifiers. vBNT (the Bancor Governance Token) is being proposed as a supported collateral type along with the BNT token in a separate proposal.
The primary focus of this UMIP is to arrive at an expiry price for the vBNT call options. Below, we will outline how to calculate the price of the options. It should be noted that the method to calculate the price is specifically a price at a given time.
