Decibel, a fully on-chain perpetuals exchange supported by Aptos Labs, has launched its fully on-chain perpetuals exchange on the Aptos mainnet. This allows users to trade perpetual contracts directly on the blockchain. All these functions run through smart contracts. This follows a substantial testnet phase with considerable activity from users.
This testnet has had more than 700,000 unique accounts. It has also had 132,000 daily active users. Daily trade volume of more than 1 million trades. Users deposit more than $58 million during the pre-deposit campaign prior to the mainnet going live.
Decibel has a fully on-chain central limit order book. This means that every trade match is on-chain. Every action is visible on the blockchain. There is no off-chain engine affecting the order book or fees.
The next great exchange was always going to be onchain.
