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

BlockBeats News, November 20, the Aptos-based full-chain transaction engine Decibel has officially launched its testnet. The protocol, built by the Decibel Foundation and Aptos Labs on the Aptos high-performance infrastructure, aims to provide a new execution and risk control framework for programmable, composable on-chain transaction scenarios.

The testnet has already supported multiple core capabilities, including: sub-second transaction execution, a full-chain risk engine developed in conjunction with Gauntlet, programmable order flow, 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 up a backend transaction API containing developer code for developers to build programmable transaction applications and receive transaction fee splits through developer code. Users are currently able to participate in testing, experience related features, and submit feedback and suggestions.
