Introduction
While decentralized trading promises a future of open access and transparent markets, in reality, most exchanges force traders to choose between performance, liquidity, and trading strategies.
Decibel was founded to deliver a decentralized trading exchange (DEX) without those trade-offs. Incubated by Aptos Labs in partnership with the Decibel Foundation, Decibel is on a mission to become the most trusted decentralized exchange in the world and the settlement layer for how all assets are exchanged. Built with a fully onchain trading engine, Decibel combines perpetuals, vault-based trading strategies, and soon, spot markets into a single platform.
“Decibel serves a market where adoption isn’t just ‘people buying crypto.’ Decibel’s traders and liquidity providers look to move serious volume onchain because they want speed, transparency, and control without trusting a centralized venue. They’re also very price sensitive and have a high bar for the infrastructure they believe allows them to keep their edge,” said Alyssa Ponzo, head of product for Decibel.
Challenge
As the team began architecting the DEX protocol, they identified a structural constraint common across many decentralized exchanges: value leakage from third-party stablecoins.
Decibel’s decentralized exchange requires traders to post stablecoin collateral for perpetual futures trading, which means significant capital can sit in the protocol at any given time. While that capital generates economic value through the reserves backing those stablecoins, using a third-party stablecoin provider means the value would be accrued solely by the issuer instead of benefitting traders using the protocol.
Instead, Decibel Foundation wanted to capture some of the value generated by a protocol-native stablecoin. This would allow the protocol to keep fees low while not relying on incentives to attract and retain traders.
“If the protocol can’t retain any of the economic value created by the collateral sitting inside it, then growth would only compound friction over time. We wanted a structure where scaling usage increases optionality and drives better fees, better reinvestment, and stronger resilience, rather than increasing dependence,” said Ponzo.
Solution
Decibel partnered with Bridge to launch usDCBL, a USD-denominated, protocol-native stablecoin designed to serve as the default collateral asset across the protocol.
Built on Bridge’s Open Issuance platform, usDCBL is fully collateralized 1:1 by cash and short-term US Treasurys held by Bridge’s institutional-grade financial partners. This gives traders the same dollar-denominated trading experience they expect while allowing value to return to traders who use the protocol.
Bridge worked closely with the Decibel Foundation to design the issuance structure and swap mechanics, so the stablecoin integrates directly into the protocol’s trading engine without altering product UX. The implementation supports customized reserve structuring, built-in liquidity mechanisms, and seamless onramps and offramps between USDC and usDCBL. usDCBL is also structured to align with the principles outlined in the GENIUS Act framework, positioning the stablecoin to remain adaptable as regulatory standards are finalized.
“Bridge facilitated the model we actually wanted, so more value can remain inside the Decibel protocol while keeping balances dollar-denominated and the user flow simple,” said Ponzo.
Results
usDCBL was launched in approximately three months, in time for the protocol’s mainnet launch.
“usDCBL helps Decibel deliver the same trading experience traders are used to, but with strong protocol economics,” said Ponzo.
With usDCBL serving as its default collateral, Decibel can retain the value generated by stablecoin reserves rather than allowing it to flow to a third-party issuer. As trading volume grows, this will help strengthen the protocol’s long-term sustainability.
As the protocol scales, Decibel Foundation now has the flexibility to reinvest the retained value from usDCBL usage into product development, infrastructure improvements, and future token-aligned mechanisms such as potential buybacks without requiring higher trading fees or aggressive incentive programs.
Conclusion
By partnering with Bridge to launch usDCBL, Decibel Foundation transformed stablecoin collateral from a third-party service into core infrastructure that allows for the protocol to strengthen its exchange economics while preserving the speed and simplicity traders expect.
