Decibel is redefining what’s possible in decentralized trading by achieving the “Impossible Trilemma” — combining speed, transparency, and composability without compromise.
Powered by Aptos’ Block-STM engine, Decibel executes transactions in parallel, not sequentially. The result:
Sub-second finality
Predictable, low fees
Massive throughput — tens of thousands of orders per second
Every order, cancel, and match happens in real time and settles atomically onchain — ensuring efficiency without sacrificing security.
Transparent by Design
Decibel leverages Aptos’ fully onchain, open-source CLOB, meaning every rule and fill is publicly verifiable.
There’s no hidden matching engine, no special treatment, and no offchain backdoors.
Fairness isn’t a promise — it’s written in code.
Composable at Its Core
With Builder Codes, vault deposit token architecture, and unified margin accounts, Decibel acts as the execution layer for the entire Aptos DeFi ecosystem.
Developers can integrate Decibel directly into their dApps, traders can post assets from vaults or lending protocols as margin, and protocols can access Decibel’s liquidity through smart contracts.
Every component is open, interoperable, and onchain — creating a truly connected DeFi experience.
You no longer have to choose between speed, trust, or freedom.
With Decibel on Aptos, you can have all three.
Fair. Fast. Composable.
That’s the new sound of trading.
