Aptos Introduces Encrypted Mempool to Combat MEV Attacks
- Aptos has launched its Encrypted Mempool feature, now live on its mainnet.
- This feature aims to protect users from maximal extractable value (MEV) attacks, such as frontrunning and sandwich attacks.
- Sandwich attacks cost Ethereum traders approximately $60 million over the last year, while Solana experienced $29.7 million in losses due to similar attacks.
- Users can opt in to encrypt transaction details until block ordering is finalized, with only the sender’s address and gas fee visible during this period.
- Encrypted transactions incur a minimum gas price at twice the network’s base rate and add around a 20-millisecond delay per block.
The Encrypted Mempool feature is designed for institutions and traders looking to mitigate risks associated with MEV attacks by keeping transaction details hidden until execution. This innovation positions Aptos alongside other networks that have implemented similar protections against harmful trading practices.
