## SUMMARY

The DVM should support price requests for SUSHI/USD, USD/SUSHI, XSUSHI/USD or USD/XSUSHI.

## MOTIVATION

The DVM currently does not support these price identifiers. SUSHI and XSUSHI are also being proposed as supported collateral types, and using these as collateral together with these price identifiers would allow SUSHI or XSUSHI holders to get leverage on their holdings by minting yield-dollar type stablecoins. Adding SUSHI/USD and XSUSHI/USD will also allow for the creation of synthetic Sushi or XSUSHI, or more bespoke contracts such as covered call options backed by SUSHI or XSUSHI.
