The APR represents the reward generated over 1 year. APR is “uncompound” and while APY is “compound”. Some staking pools can have a fixed APR or have a variable APR instead. On UpBots platform UBXT staking APR is variable, due to the fixed distribution planned per block. Each block we distribute the same amount of UBXT. Then, the more UBXT staked on the pool, the lower the reward per UBXT. The APR is then totally automatic and the % of reward depends on your share of the pool.
