Live on Unichain: Fair Transaction Ordering and MEV Protection

Posted: May 1, 2025 | Effective: May 1, 2025

Unichain became the first L2 to build blocks inside a Trusted Execution Environment (TEE). This upgrade increased transparency in block building, reinforced priority ordering, mitigated extractive MEV, and introduced support for revert protection.

Powered by Rollup-Boost, the TEE-based block builder on Unichain was built by Uniswap Labs and Flashbots.
