Aptos has proposed a novel Encrypted Mempool system designed to combat frontrunning and MEV by keeping transactions private until execution. The native protocol-level feature would allow users to submit encrypted transactions with a single click, with all data becoming transparent on-chain after block confirmation. This system aims to protect users while maintaining network speed and security.
The Aptos blockchain has introduced a proposal for a native Encrypted Mempool system. This system aims to allow users to submit transactions privately while preserving network speed and transparency.
Aptos stated its encrypted mempool keeps transactions private until execution. Complete transaction data is revealed transparently onchain afterward.
If approved through governance, Aptos said the feature would make it the first Layer 1 with built-in encrypted transaction submission. The system targets protection from frontrunning, censorship, and orderflow manipulation.
“Aptos said its encrypted mempool keeps transactions private until execution while still revealing complete transaction data transparently onchain afterward.” The company explained the proposal responds to growing decentralized exchange activity.
DEX spot trading volumes regularly surpassed $200 billion monthly in 2025. They averaged roughly $476 billion monthly during the third quarter.
Aptos Labs explained the system relies on threshold cryptography and distributed key generation. A batched threshold decryption scheme reduces communication and computation overhead.
The company further revealed the system prevents replay attacks and avoids transaction resubmissions. It integrates directly into the consensus protocol with minimal added latency.
Its native token, APT, climbed from around $0.82 in mid-April to nearly $1.10 by mid-May. Over the past 24 hours, it declined by almost 2% to trade near $1.10.
