Odaily Planet Daily News: Decibel, a cross-chain trading engine incubated by Aptos Labs, has officially launched, enabling users to trade on-chain perpetual contracts on Aptos’ high-performance infrastructure. The mainnet version features a fully on-chain limit order book with verifiable trades, a transparent on-chain risk engine, a DLP liquidity pool co-developed with Gauntlet, and an X-Chain account system supporting fund deposits from Aptos, Ethereum, Solana, and centralized exchanges. The protocol’s native USD stablecoin, usDCBL, issued via Bridge, serves as the default collateral asset, complemented by institutional-grade tools and an open developer layer with Builder Codes.
During the testnet phase, over 700,000 unique accounts and 132,000 daily active accounts were generated, with more than 1 million daily transactions and $58 million in deposited funds, approximately 50% of which came from users in the Solana and Ethereum ecosystems. Looking ahead, Decibel plans to expand from the crypto perpetuals market to spot markets, a unified account system, and multi-collateral structures, while exploring on-chain integration for real-world assets, stock indices, and foreign exchange markets—to bring additional institutional-grade trading volume to the Aptos ecosystem.
