Optimism confirmed OP’s placement in AeroXYZ’s boarding group 1 for an MEV-tax trial covering Slipstream V3 pools on OP Mainnet. The test aims to route value associated with miner extractable value (MEV) to people providing liquidity to the pools and to sAERO holders.

OP Mainnet is an Ethereum layer-2 network built to process transactions faster and at lower cost. The new detail builds on TokenPost’s [earlier coverage of AeroXYZ’s Slipstream V3 MEV-tax test](<https://www.tokenpost.com/news/technology/47062>).
