## Summary

This UMIP proposes to revoke UMA token minter role for deprecated voting contracts.

## Motivation & Rationale

During each of DVM upgrades the new voting contracts got granted minter role for the UMA voting token while the previous
 contracts privileges were not revoked. Even though the minter role is only used to claim rewards, it is still
 considered a good security practice to revoke the minter role for deprecated contracts in order to reduce potential
 attack surface.
