Aptos' on-chain transaction engine Decibel launches on testnet, unlocking several key features.

Odaily Planet Daily reports that Decibel, a full-chain trading engine based on Aptos, has officially launched its testnet. This protocol, jointly built by the Decibel Foundation and Aptos Labs using Aptos' high-performance infrastructure, aims to provide a new execution and risk control framework for programmable and composable on-chain trading scenarios. The testnet already supports several core capabilities, including: sub-second transaction execution, a full-chain risk engine co-developed with Gauntlet, programmable order flow, encrypted mempool, gas-free cross-chain deposits, batch orders, sub-accounts, and real-time price data and risk monitoring based on Chainlink.

In addition, the Decibel testnet simultaneously releases a backend trading API containing developer code, allowing developers to build programmable trading applications and earn a share of trading fees through their code. Users can currently participate in testing, experience the features, and submit feedback.
