Formula
daily_btc = (usdb_balance * apy_rate / 365) / btc_priceMinimum 10 USDB to earn rewards. Maximum rewards on 500,000 USDB.

​
Requirements

  • Minimum balance: 10 USDB to earn rewards
  • Maximum balance: 500,000 USDB (rewards capped at this amount)
  • Payout timing: Daily at 00:00 UTC
  • Payout currency: BTC (deposited to your Spark wallet)

​
How Rewards Are Calculated

Your daily reward is based on your Time-Weighted Average Balance (TWAB), not a snapshot. For example, if you hold 1,000 USDB for 12 hours then 2,000 USDB for 12 hours, your TWAB is 1,500 USDB. This prevents gaming by depositing right before the daily cutoff. Daily reward formula: 
daily_reward = (TWAB * reward_rate) / 365
The reward is converted to BTC at the current exchange rate and deposited to your wallet.
