Using USDB
You can hold a dollar balance alongside BTC and move between them when you trade. Spark-to-Spark transfers are free and settle in under a second. Rewards start at a balance of 10 USDB. Your trading volume determines your rate, and rewards arrive in BTC without staking or locking your USDB. See Rewards for the tiers, balance limits, and calculation. To get started, bridge USDC or swap BTC for USDB. You can convert USDB back to BTC or USDC through Flashnet Trade.How USDB is Backed
USDB is issued by Brale, a regulated US-based stablecoin issuer. Brale reports that USDB is fully backed by US Treasury bills, cash, and cash equivalents. Brale manages issuance, reserves, and direct redemption. Flashnet runs the rewards program. Transparency explains these separate roles.Token Details
