Aptos (APT) has launched an encrypted mempool on its mainnet, allowing users to conceal transaction details until execution to protect against MEV attacks, where bots exploit information about pending transactions for their own benefit.

This feature is aimed at crypto investors who need to keep transaction parameters hidden until execution.

Encryption is optional

The feature is optional: users can choose whether to apply encryption to their transactions.

Addresses and fees remain public

When using the encrypted mempool, sender addresses and transaction fees remain visible, while other details are hidden until execution.

Reducing the risk of bot activity in the mempool

The mechanism is designed to reduce the impact of MEV strategies that rely on access to information about pending transactions.
