The distributor contract receives minted OHM from the treasury in order to drip-feed rewards to stakers. The reward rate target as of time of writing is set to 3500, which translates to 0.35% of total supply, since the reward rate is defined in tens of thousands. Note that the reward rate determines the rebase rate and that the rebase rate determines the APY.
