The APR is the fixed interest rate applied to your respective subscriptions. Rewards begin to accrue the day after you subscribe, starting at 00:00 UTC. You will start receiving the rewards distributed to your L2 Wallet on the day after the accumulation begins (two days after subscribing), between 00:00 UTC and 08:00 UTC.
Daily Rewards = Deposited Assets * APR / 365 (Rounded down to 5 decimal places).
You cannot unsubscribe until the contract period ends, so consider carefully before locking your assets, as you will not be able to use the locked assets during the contract period.
