Aptos' brand-new on-chain transaction engine, Decibel, has launched its testnet, unveiling several key features.

On November 20th, the Aptos-based full-chain transaction engine Decibel officially launched its testnet. Constructed by the Decibel Foundation and Aptos Labs on the Aptos high-performance infrastructure, this protocol aims to provide a new execution and risk control framework for programmable and composable on-chain transaction scenarios. The testnet has already supported multiple core capabilities, such as sub-second transaction execution, a full-chain risk engine developed in collaboration with Gauntlet, programmable order flow, an encrypted mempool, gas-free cross-chain deposits, batch orders, sub-accounts, as well as real-time price data and risk monitoring based on Chainlink. In addition, the Decibel testnet has concurrently opened a backend transaction API that contains developer code, enabling developers to build programmable transaction applications and receive transaction fee splits through developer code. Currently, users are able to participate in testing, experience relevant features, and submit feedback and suggestions.
