Decibel Trade switches on Aptos’ Encrypted Mempool to shield trader orders

The Aptos-incubated exchange now lets users encrypt order details before they hit the chain, aiming to blunt frontrunning and sandwich attacks Decibel Trade has turned on Aptos ’ Encrypted Mempool. Traders on the onchain exchange can now hide the details of their orders while those transactions are still pending. Think of a mempool as a public waiting room. Transactions sit there before validators bundle them into a block, and anyone watching can see who is in line and what they plan to do. That visibility is the problem. Bots scan the waiting room, spot a large buy, and slip their own trades in before and after it. These tactics are called frontrunning and sandwich attacks, and the trader on the receiving end pays for them through worse prices.
