Aptos Deploys Encrypted Mempool to Shield Users From Bots
By Damilola Esebame
AI summary of the source article
Aptos has activated an opt-in encrypted mempool on its mainnet following governance approval of AIP-144. The feature relies on batched threshold decryption by validators to shield transaction payloads until blocks reach finality.
Why it matters
Aptos stated that "Bots use that visibility to trade against you or copy your strategy," framing the encrypted mempool as a direct counter to automated extraction.
Key facts
- Aptos launched the encrypted mempool on October 12, using stake-weighted threshold decryption by its own validator set after block finalization.
- Encrypted transactions double the minimum gas-unit price to 200 octas, incur an added 375 gas units for decryption, and add around 20 milliseconds of block latency.
- Petra is the first wallet to integrate the encryption option, and perpetual futures exchange Decibel plans to use it for private pending orders.
