Decibel, an on-chain trading protocol, started operations on the Aptos devnet, combining spot trading, perpetual futures and yield strategies into a single interface.

The test environment, invite-only for now, offers simulated access to cross-margin trading, composable vaults and high-speed order execution. The system is designed to mimic centralized exchange performance while preserving the transparency of decentralized finance DeFi ( DEFT ).

The introduction comes at a time of growing demand for performant on-chain infrastructure. According to industry data, decentralized exchanges (DEXs) saw over $876 billion in volume in the second quarter, with weekly DeFi ( DEFT ) activity surpassing $48 billion across more than 14 million wallets.

The platform is backed by the Decibel Foundation, which oversees the protocol's development, and Aptos Labs, the team behind the layer-1 blockchain it runs on.

Built natively on Aptos, Decibel is positioned as a core part of the blockchain’s financial infrastructure. According to the developers, the platform is meant to function as an execution layer alongside Aptos' stablecoin payments systems and Shelby, its decentralized data storage protocol.

“We’re not just building another trading platform — we’re creating the execution layer,” said Oliver Bell, board director at the Decibel Foundation in a press release.

Decibel's architecture is designed to address common pain points like fragmentation and poor capital efficiency. It supports a multicollateral system and allows vault deposits to serve as collateral.

Aptos Labs contributed to building the protocol and will continue supporting its development under an agreement with the Decibel Foundation. The team behind the project says future upgrades aim to scale performance to 1 million orders per second, with sub-20ms block times — targets that, if met, could put Decibel on par with top-tier centralized exchanges.
