Decibel, an on-chain trading engine co-incubated by Aptos Labs and built on the Aptos blockchain, has announced a partnership with Bridge, a stablecoin infrastructure company under Stripe, to launch the protocol-native stablecoin USDCBL. This stablecoin will serve as Decibel's default collateral asset, streamlining the collateralization process. USDCBL is issued through Bridge's Open Issuance platform and is backed by USD reserves. Once Decibel's mainnet is live, users will be able to convert USDC deposits into USDCBL. Decibel has already opened pre-deposit functionality and initially supports on-chain perpetual contract trading, with plans to introduce spot and RWA trading features in the future.
