pub type ClaimedRewards<T: Config> = StorageDoubleMap<_GeneratedPrefixForStorageClaimedRewards<T>, Twox64Concat, T::AccountId, Twox64Concat, <<T as Config>::Currency as MultiTokenCurrency<<T as Config>::AccountId>>::CurrencyId, <<T as Config>::Currency as MultiTokenCurrency<<T as Config>::AccountId>>::Balance, ValueQuery>;
