$APT Aptos’s encrypted on-chain mempool is now connected to an exchange: Aptos announced this morning Beijing time that the on-chain perpetuals exchange Decibel now supports the feature.
Aptos is a public blockchain whose smart contracts are written in Move. APT is used to pay transaction fees and stake with validators to help maintain the network.
The feature is simple: while a transaction is waiting to be added to the blockchain, its order details are encrypted on the user’s own device. Validators can’t see what kind of order you’re placing when they produce a block. The details are only decrypted and executed once the block is finalized.
It addresses a longstanding problem with on-chain exchanges: others can see your order first and trade ahead of you, in what’s commonly known as an MEV sandwich attack. Hiding order details gives bots less to go on when trying to front-run, while trade records remain verifiable on-chain afterward.
Decibel says front-running protection is enabled by default in its interface. If the network temporarily suspends this protection, orders will first be submitted the usual way and encrypted once protection is restored.
One thing to note: the sender’s address and transaction fee are still visible; only the order details are hidden. Aptos’s encrypted trading feature went live on mainnet on October 16, initially allowing users to choose whether to enable it for each order.
