Svmuu News: Decibel, a full-chain trading engine incubated by Aptos Labs, has officially launched, enabling users to trade on-chain perpetual contracts on Aptos’s high-performance infrastructure.Mainnet features include an on-chain limit order book that verifies all transactions, a transparent on-chain risk engine, a DLP liquidity pool co-developed with Gauntlet, and an X-Chain account system supporting fund transfers from Aptos, Ethereum, Solana, and CEX fund on-ramps. It utilizes the protocol’s native USD-pegged stablecoin, usDCBL, issued via Bridge, as the default collateral asset, and is equipped with institutional-grade tools and an open Builder Codes developer layer.During the testnet phase, the platform generated over 700,000 unique accounts and 132,000 daily active users, with an average of over 1 million daily trades, and raised $58 million in pre-deposits, approximately 50% of which came from users in the Solana and Ethereum ecosystems.Moving forward, Decibel plans to expand from the crypto perpetual futures market into spot trading, a unified account system, and multi-collateral structures. It also aims to explore on-chain solutions for real-world assets, stock indices, and foreign exchange markets, with the goal of bringing more institutional-grade trading volume to the Aptos ecosystem.
