Rollup-Boost goes live on Unichain, building blocks inside secure hardware enclaves

Uniswap Labs/Unichain

Unichain became the first layer-2 to build blocks inside a trusted execution environment (secure hardware enclave), using Rollup-Boost built with Flashbots. Transactions are ordered by priority fee from an encrypted mempool, and failed trades on participating apps incur no gas.

• Rollup-Boost sequences transactions in a TEE rather than traditional offchain sequencing; ordering based on transparent, verifiable rules.
• Private, encrypted mempool limits MEV extraction; developers can implement value-capture mechanisms via verifiable block construction.
• Failed transactions (revert-protected) cost no gas via pre-simulation; reduces developer friction for state-dependent operations.
• Foundation for Flashblocks (200 ms sub-blocks) and future encrypted mempools and scheduled transactions.
