Aptos Curb Frontrunning & Sandwich Attacks with Encrypted Mempool Feature

Introduction

Aptos has rolled out an optional new feature called Encrypted Mempool to curb frontrunning and sandwich attacks on its blockchain.

How it Works

The feature hides transaction details until their order is finalized, preventing bots from exploiting pending trades.

Benefits

Aptos said the feature was built for institutions submitting large transactions to the chain, traders wanting to avoid MEV risk, AI agents and builders.

Impact

The protection comes with added costs and a small delay.

Comparison to Other Networks

Aptos joins other networks offering protection against harmful MEV, including Gnosis Chain's encrypted mempool and Ethereum's Flashbots Protect routes transactions privately to block builders.

Conclusion

Aptos' distinction is that its existing validators handle both transaction ordering and decryption, rather than relying on a separate decryption committee or trusted builders.
