Decibel, a trading engine built on Aptos, and Bridge have launched USDCBL, a protocol-native USD-backed stablecoin via Bridge's Open Issuance platform. The stablecoin secured over $42 million in pre-deposits within 12 hours, indicating strong initial demand. USDCBL will be Decibel's default collateral for perpetual contracts, with future plans to expand usage to spot and real-world asset trading.
