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).
