# Summary
This UMIP proposes adding GYSR, MPH, APW, SNOW, and NDX for use as collateral in UMA contracts. This will involve adding these to the whitelist and adding flat final fees to charge per-request.
# Motivation
The addition of these collateral currencies offers additional functionality to the UMA protocol and increases the range of contracts that can be built.
These could be used with *token*/USD price identifiers that are also being proposed to create yield dollars or covered calls collateralized by each of these tokens, among many other use cases.
