According to @ItsDave_ADA, over the last 60 days one of Solana’s largest validators, Helius, validated 412,325 blocks, and 2,960 of those blocks (0.72%) contained at least one sandwich attack, underscoring how widespread MEV has become on Solana; source: @ItsDave_ADA (X, Oct 4, 2025). Some validators recorded a sandwich-attack rate as high as 27.34% of blocks produced over the same period, highlighting significant exposure variability across validators; source: @ItsDave_ADA (X, Oct 4, 2025). The author characterizes this as technical users extracting value from non-technical users, a direct MEV concern for on-chain traders and liquidity takers on Solana DeFi; source: @ItsDave_ADA (X, Oct 4, 2025).

According to @ItsDave_ADA, Helius validated 412,325 Solana blocks over the last 60 days, with 2,960 blocks or 0.72% containing at least one sandwich attack, indicating measurable MEV presence on Solana — source: @ItsDave_ADA on X - Oct 4, 2025. He adds that some validators saw sandwich activity in as many as 27.34% of their blocks during the same period, showing uneven but significant validator-level exposure — source: @ItsDave_ADA on X - Oct 4, 2025. He characterizes this as a clear sign of how widespread the issue has become on Solana, where technical users extract value from non-technical users, underscoring a MEV problem that SOL traders should factor into on-chain execution considerations — source: @ItsDave_ADA on X - Oct 4, 2025.

According to the source, threshold encryption keeps transaction payloads encrypted until ordering, reducing exploitable mempool visibility that enables frontrunning and sandwich attacks on Ethereum (source: Shutter Network documentation; Daian et al., Flash Boys 2.0, 2019). Shutter is a pioneer of threshold-encrypted order flow for Ethereum/Gnosis, aiming to mitigate MEV without changing user UX (source: Shutter Network documentation). Lower public mempool visibility can reduce extractable value per block and thus validator tip-based rewards, which currently include MEV via MEV-Boost across a large share of Ethereum blocks (source: Ethereum Foundation staking economics; Flashbots MEV-Boost adoption data, 2023). For execution quality, routing swaps through threshold-encrypted or protected orderflow reduces sandwich risk and slippage versus public mempool submission (source: Shutter Network documentation; Flashbots Protect RPC documentation). Traders should monitor realized validator rewards and staking APR for ETH and liquid staking tokens as MEV-related tips are a component of staking yields (source: Ethereum Foundation staking documentation; Flashbots research on MEV and PBS). Finally, DEXs and wallets integrating encrypted mempools or orderflow auctions may capture more orderflow and fees as users seek MEV protection, impacting liquidity distribution and gas dynamics (source: Flashbots SUAVE research; CoW Protocol documentation on MEV-minimized orderflow).

According to the source, research indicates MEV remains persistent, with around $300K lost to sandwich attacks in the last month (source: X post dated Oct 2, 2025). According to the source, threshold encryption protects orderflow by encrypting the mempool until block inclusion and splitting decryption keys across a committee so even block proposers cannot view contents (source: X post dated Oct 2, 2025). According to the source, Shutter pioneered this approach, evolving from per-epoch to per-transaction encryption, and it is now live on Gnosis Chain via its RPC endpoint (source: X post dated Oct 2, 2025). According to the source, a critical flaw was revealed whereby reconstructing an epoch key made all transactions public, including those not yet included in a block (source: X post dated Oct 2, 2025). Based on the source, traders active on Gnosis Chain should monitor DEX slippage, sandwich attack incidents, and RPC route selection, as execution quality may depend on adoption of per-transaction encryption and avoidance of configurations affected by the epoch-key exposure (source: X post dated Oct 2, 2025).

According to @ItsDave_ADA, nearly 1 in 4 blocks from certain Solana validators include sandwich attacks, with BT8LZ at 24.8%, Majestysol at 15.9%, Custodian at 14.7%, and UZB at 13.8% as reported in his X post. According to @ItsDave_ADA, this is MEV by design, where validators run pipelines that extract value while traders are front-run and drained on Solana DEX order flow. According to @ItsDave_ADA, Solana’s architecture allows this behavior, leaving everyday users exposed to value extraction by wealthier validators.

According to @deanmlittle on Twitter, MySQL’s infrastructure has supported swappers for 30 years without any reported losses from sandwich attacks, a stark contrast to the hundreds of millions lost to such attacks in other platforms. This historic security record reinforces confidence in MySQL-backed crypto trading systems, making them an attractive choice for traders seeking reduced risk and enhanced protection against common DeFi exploits (Source: @deanmlittle, Twitter, May 24, 2025).

According to @jessepollak, since the launch of Base blockchain 18 months ago, swappers have lost $0 to sandwich attacks, which contrasts sharply with the hundreds of millions lost to such exploits on other networks (source: Twitter/@jessepollak, May 23, 2025). This security record positions Base as a safer choice for DEX traders, potentially attracting higher trading volumes and increasing user confidence in decentralized finance protocols. With sandwich attacks remaining a critical risk on other blockchains, Base's technology could influence broader crypto market migration and spark heightened interest from institutional and retail investors seeking secure trading environments.
