Decibel Trade activates Aptos Encrypted Mempool to shield traders from MEV
Decibel Trade has enabled Aptos' Encrypted Mempool on its platform, letting traders hide order details before execution to reduce frontrunning and sandwich attacks.
Why it matters
Encrypted mempools address a structural MEV problem that has cost traders across major blockchains. Aptos' implementation at the protocol level, now live on a trading venue, tests whether opt-in encryption can meaningfully reduce extraction without degrading throughput.

What happened
Decibel Trade has activated Aptos' Encrypted Mempool feature on its decentralized trading platform, allowing users to encrypt transaction payloads while keeping sender addresses and gas fees visible. The opt-in feature, which went live on Aptos mainnet on October 12 under AIP-144, uses collective validator decryption after block finalization. Aptos benchmarking showed roughly 20 milliseconds of added latency per block in a 50-node test. The move aims to curb maximal extractable value (MEV) by preventing bots from seeing pending trades and front-running or sandwiching them. Both Crypto.News and Bitcoin Insider report the launch, with the latter syndicating coverage from CryptoBriefing and crypto.news.
