🔎 RESEARCH: Sandwich attacks on Ethereum drained nearly $40M from users in 2025, yet extraction has fallen sharply even as DEX volumes surged from $65B to over $100B monthly, per EigenPhi data.Monthly sandwich extraction dropped from ~$10M in late 2024 to just $2.5M by October 2025, while attack frequency remained high at 60K-90K per month.Most concerning: 38% of attacks targeted low-volatility pools including stablecoins and wrapped assets, with 12% hitting stable swaps where slippage is unexpected and esp ...

Blockchain Security - MEV (Miner Extractable Value) is a persistent issue, with approximately $300 thousand lost to sandwich attacks last month [1] - Threshold encryption offers protection by encrypting the mempool, hiding transactions until block inclusion [1] - Shutter pioneered threshold encryption, initially with per-epoch encryption, later improved to per-transaction encryption, now live on Gnosis Chain [1] Vulnerabilities - A critical flaw was revealed: when the epoch key was reconstructed, all transactions became public, including those not yet included in the block [2]

Solana Ecosystem Improvement - Addresses three major critiques: extractive sandwich attacks, institutional sequencing control, and onchain CLOB building difficulties [1] - Introduces a solution that tackles all three issues simultaneously [1] Key Technological Advancements - Implements a private encrypted mempool to prevent sandwich attacks [1] - Enables app-specific sequencing for building onchain CLOBs [1] - Provides verifiable ordering, allowing institutions to build without MEV concerns [1] - Improves transaction landing efficiency [1] Industry Impact - Represents a significant change in Solana's history [1]
