Aptos-based 'Decibel' to introduce proprietary stablecoin ahead of mainnet launch this month

The Decibel Foundation, incubated by Aptos Labs, will introduce its protocol-native stablecoin, “USDCBL,” ahead of the launch of its decentralized derivatives exchange mainnet later this month.

On the 11th (local time), the Decibel Foundation said via its official X account that it will issue USDCBL, a U.S. dollar-pegged token, through the “Bridge” platform—acquired by fintech firm Stripe late last year. Users will deposit existing USDC and convert it into USDCBL to use as collateral for on-chain perpetual futures trading.

The move is a strategy to avoid reliance on external stablecoin issuers and internalize within the protocol the economic benefits from reserve management. The foundation said USDCBL’s reserves will consist of cash and short-term U.S. Treasuries, and it plans to reinvest the resulting interest income into protocol development and ecosystem expansion. This, it said, could reduce dependence on trading fees or incentive programs. The foundation emphasized, “This is not simply launching yet another stablecoin, but building the exchange’s core infrastructure.”

Decibel is a decentralized derivatives exchange built on the Aptos network and has adopted a fully on-chain model using a single cross-margin account. According to the foundation, more than 650,000 unique accounts participated during the testnet period in December, and daily transaction volume surpassed 1 million.
