The Governance Rewards deposit balance accrued through Governance that an xGov uses to vote in xGov voting sessions. For example, if your Governance Rewards balance from Term 1 Pool was 100 Algo, your xGov Voting Power would be 100,000,000 mAlgo. You need to use all of your xGVP during each voting session. The xGVP renews at the start of each session. Learn more about xGVP.
