币界网报道：Bitcoin blockchain now has its first native dollar-pegged stablecoin, USD Backed (USDB), launched by blockchain startup Stably. The stablecoin is issued on the Bitcoin network via the Stably Bridge, which connects to multiple blockchains including Ethereum, BNB Chain, and Polygon. USDB is fully collateralized by U.S. dollars held in FDIC-insured banks, with reserves audited by third-party accounting firm Armanino. Stably CEO Kory Hoang emphasized that USDB aims to bring DeFi capabilities to Bitcoin, enabling lending, trading, and payments without relying on wrapped Bitcoin or Layer 2 solutions. The launch follows growing demand for stablecoins on Bitcoin, particularly after the Taproot upgrade improved smart contract functionality. Stably plans to expand USDB's utility by integrating with Bitcoin DeFi platforms like Sovryn and Arkadiko.
