Why Bitcoin
Most reward programs pay in the same currency you're holding. Dollars in, dollars out. But the dollar depreciates over time by design. Central banks target inflation. Since 1913, the dollar has lost 96% of its purchasing power.
Earning rewards in dollars means accumulating more units of a shrinking currency.
Bitcoin operates on different rules. No central bank, no monetary policy committee. Supply is fixed at 21 million, enforced by code and verified by a global network every ten minutes. Over fifteen years, Bitcoin has appreciated against the dollar faster than traditional assets. An asset with hard-capped supply in a world of expanding money supply has a structural advantage.
Dollar Stability, Bitcoin Growth
Your balance stays denominated in dollars, backed 1:1 by U.S. Treasury bills through Brale, a licensed U.S. financial institution.
Rewards come in Bitcoin. Every day, BTC lands in your wallet. Your stable balance stays stable. Your rewards accumulate in an appreciating asset. You hold a unit designed to depreciate while earning one designed to appreciate.
No Complexity
Other reward mechanisms ask you to stake, lock, or deposit into smart contracts. USDB asks nothing. Rewards accrue automatically to your wallet. Transfer freely. Exit whenever you want. No penalties, no waiting periods.
Reward Tiers
All USDB holders earn rewards. Your rate scales with trading volume on Flashnet, up to 6% annually. Tiers update continuously based on rolling 24-hour volume. Active traders earn more, but passive holders still earn.
Flashnet funds rewards from protocol fees and liquidity provision revenue. Full breakdown: docs.flashnet.xyz/usdb/transparency
Native to Bitcoin
USDB runs on Spark, Bitcoin's fastest layer. Sub-second settlement, no bridges, no wrapped tokens, no counterparty chains. Your dollars and your rewards stay on Bitcoin infrastructure.
The Long Game
Flashnet helped build USDB for people who think in years. Dollar stability protects your principal. Bitcoin rewards compound over time in an asset with structural tailwinds.
We'll announce another rewards program for active traders in the coming weeks.
