🔐 Your limit orders shouldn’t become someone else’s signal

Decibel, a fully on-chain exchange on Aptos, has just launched an Encrypted Mempool feature.

Simply put: while an order is waiting to be filled, its details are encrypted. They’re only revealed once validators have produced a block, and the trade is then settled publicly on the Aptos blockchain as usual.

🔹 Order details are encrypted on the client side, so others can’t see them while they’re pending
🔹 The sender’s address and gas fees are still visible
🔹 The goal is to reduce MEV losses from front-running and sandwich attacks
🔹 Incubated by Aptos Labs, without the compromises of off-chain matching

Someone in the community put it well: your order flow doesn't have to be someone else's signal.

My take: the biggest awkwardness of on-chain trading is that “transparency” means bots can see everything too. The moment you place an order, others see it and can act first. Building encryption into the mempool is much more reliable than making users adjust slippage or split up their orders themselves.

But don’t overhype it. Addresses are still visible, and people will still monitor whale activity; some data, such as position sizes, is also still subject to limitations. What’s really worth watching is how many orders are using it two weeks from now, and whether the trading experience has improved.

Have you ever been sandwiched while trading on-chain? Would you switch exchanges for protection against sandwich attacks? 👇
