What is Decibel?

Decibel is a trading engine for global markets, built on the Aptos blockchain to deliver on-chain execution for perpetual futures (perps) and spot trading with sub-125ms block times, ensuring transparent order matching, fills, and cancellations without any off-chain logic or centralized components.

It leverages a composable DeFi stack to aggregate deep liquidity across Aptos, enabling tight spreads, low slippage, and high fill rates at scale, while supporting multi-asset collateral, cross-margin accounts, and user-managed vaults for flexible position management and yield generation through integrated protocols.
