# Encrypted Mempools Reach Production

More base layers will ship encrypted or threshold-decrypted mempools to stop front-running and MEV extraction. Ordering without seeing transaction contents then becomes a standard feature that chains compete on. The trade-offs that recur with each launch are added latency, sender and fee metadata that stays visible, and the trust placed in decryption committees.

## Recent evidence

- [confirms] Aptos Turns On an Optional Encrypted Mempool on Mainnet to Hide Pending Trades From Front-Runners (2026-10-13): Aptos turned on an optional encrypted mempool on mainnet. Validators order transactions without seeing their contents until the block is final, while the sender address and fee stay visible. Tests showed about 20 milliseconds of added delay per block.
