Aptos Encrypted Mempool is now live on mainnet (AIP-144, launched 10-12): the client encrypts the payload (function + arguments) before signing; validators order transactions blindly, then collectively decrypt and execute them after finality, with 2/3 of the stake. Addresses and gas remain visible throughout. Petra already offers a checkbox in the signing flow; the team says ZKSecurity conducted an independent review, and a 50-node benchmark showed about +20 ms per block.
An engineer’s breakdown (vs. Flashbots Protect / TEE / external keypers):
· The first three all require trusting one more person or a committee; with Aptos, the decryption parties are the consensus validators themselves—no new trust assumptions
· Minimum gas for encrypted transactions is ≈ 2× the baseline (according to public technical materials); the privacy premium is transparent, and you choose whether to pay it
· It protects against front-running and sandwich attacks enabled by mempool visibility. It won’t protect you from signing fake approvals yourself, handing over your seed phrase, or buying a device tampered with in the supply chain
What you can do: For large transactions or sensitive interactions, enable the encryption option if your wallet offers it. Still use bookmarks to visit sites, check addresses character by character, and never sign an approve you don’t understand. Don’t mistake an MEV shield for an anti-scam shield.
Encrypted mempools are cool, but a sweet-talking customer support agent asking for your seed phrase is costlier than any sandwich bot 😏
