According to Cointelegraph, Aptos has rolled out an optional feature called the Encrypted Mempool. The design keeps transaction details hidden while a transaction is pending and only reveals them after it is finalized. This approach aims to stop automated bots from seeing and acting on upcoming trades before they are confirmed.
The encrypted mempool does not alter how users submit or execute transactions; it simply delays visibility of the full transaction data until finalization. By preventing early access, the feature reduces opportunities for frontrunning—where a third party places a trade ahead of a visible pending order—and sandwich attacks, in which an attacker inserts their own trade around a user’s trade to manipulate price.
Aptos describes the feature as optional, meaning users can choose whether to use it when submitting transactions. The rollout occurs on the Aptos blockchain network without changes to core protocol rules or transaction processing speed. No timelines for mandatory adoption were mentioned.
The move reflects ongoing efforts by the Aptos team to improve trade fairness through technical design choices that limit bot exploitation of pending state. Further details on integration, testing, and user guidance are not specified in the announcement.
