Aptos Pushes Encrypted Mempool Upgrade to Protect Users From Frontrunning and Censorship

Aptos is suggesting a new system called an Encrypted Mempool. This would let users send transactions privately without slowing down the network or sacrificing its openness.

Aptos announced that if its community approves the change, it would be the first blockchain of its kind to allow users to submit encrypted transactions directly through the network itself.

Aptos Targets MEV Exploitation

This system safeguards users against unfair practices like frontrunning, censorship, and manipulation of transaction order. It allows users to send secure, encrypted transactions with just one click. Once a transaction is confirmed on the blockchain, the details will become publicly visible.

Aptos explained that this proposal is being introduced because trading on decentralized exchanges (DEXs) is booming. In 2025, monthly trading volume on these exchanges often exceeded $200 billion, and averaged around $476 billion during the third quarter. While DEXs eliminate the need for traditional, centralized systems, Aptos points out that most blockchains still reveal transactions before they’re fully confirmed. This means validators and others on the network can see trades before they happen, potentially allowing them to take advantage of that information.

Aptos explains that current transparency in how transactions are handled has fueled a growing market where validators and traders can profit by rearranging or taking advantage of unconfirmed transactions. Their new Encrypted Mempool is designed to prevent this by keeping transaction details private until they’re processed, all while maintaining the network’s existing security standards.

Aptos Labs says their system uses a special type of encryption and a process where keys are created and shared before each period of operation. Transactions are sent as coded messages, and validators work together to decode them only after the order of transactions is decided. Unlike other encrypted transaction systems, this approach avoids major slowdowns. Traditional systems require validators to handle and communicate partial decryptions for every transaction, which creates a lot of network traffic, processing demands, and delays.

As a crypto investor, I’m really excited about this new tech Aptos is using. Basically, their team came up with a way for the network validators to decrypt a whole bunch of transactions at once, instead of one by one. This is a game-changer because it massively cuts down on the amount of data flying around and the processing power needed. A lot of the heavy lifting can even be done *before* the transactions are fully confirmed, making everything much faster and more efficient.

Aptos announced that its new system safeguards against replay attacks, eliminates competition for encryption resources, and prevents duplicate transactions. The company also stated that this encrypted transaction pool works seamlessly with the network’s core process and doesn’t significantly slow things down.

APT Price Action

The price of APT, the token native to the platform, has been consistently increasing over the last month. It went from about $0.82 in mid-April to almost $1.10 by mid-May, with a brief peak above $1.20 before settling slightly lower.

Over the past 24 hours, however, it declined by almost 2% to trade near $1.10.
