The APR of Reward Pools shown on the website is an estimate and average calculated by using the current staking amount and bridgings from the last 7 days (except for the initial days after a new token listing when no 7-day history is available. In this case, the longest available period between 24 hours and 7 days is taken). The actual Rewards depend on the amount staked as well as the size & amount of bridgings that occur in the future. The greater the amount staked and the size & amount of bridgings, the higher the collected protocol incentive or bridging fees, meaning the higher the rewards.
