Requires auth of the dapp.fusion contract (anyone can make this happen by calling claimgbmvote on the dapp.fusion contract)

### claimrefund

> Claims refunds from the system contract if any are available. Requires auth of the dapp.fusion contract (anyone can make this happen by calling claimrefunds on the dapp.fusion contract)

### initstate

### unstakebatch

> Unstakes WAX from the system contract, in order to transfer it back to the dapp.fusion contract and make it available for redemptions. Requires auth of the dapp.fusion contract. Anyone can initiate this process by calling unstakecpu on the dapp.fusion contract.
