Decibel Testnet has introduced a new onchain trading engine designed for rapid execution and enhanced transparency. The platform, now open for testing, features sub-second execution speeds, Chainlink-powered price feeds, and a fully onchain risk management system. Users are encouraged to engage with the testnet to help refine the system before its mainnet launch. The trading engine supports spot trading, perpetual contracts, and yield opportunities on the Aptos blockchain, aiming to streamline DeFi processes. Participants can access the testnet application, documentation, and community channels to contribute feedback and influence the platform's development.
