## Summary (2-5 sentences)
The DVM should support price requests for the ARS/USD price index.


## Motivation
The DVM currently does not support the ARS/USD price index.

Supporting the ARSUSD price identifier would enable the creation of an Argentine Peso stablecoin, backed by USD. Token minters could go short on the ARS/USD index, while token holders could go long or use synthetic ARS for functional purposes.

One practical use for synthetic ARS is in trading pairs on Argentinian cryptocurrency exchanges.

There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available.
