Optimism - Stake-Based Tx Ordering - 16 July 2026

Optimism has launched stake-based transaction ordering on the Sepolia testnet, allowing OP stakers to gain “top-of-block access,” with mainnet to follow after testnet learnings, as outlined in their announcement on X (source). Mechanically, this shifts part of the transaction-ordering power and associated MEV opportunities toward addresses that stake OP, potentially turning OP into the key asset required for privileged blockspace access. If implemented on mainnet, this could increase demand to hold and lock OP, reducing liquid supply and supporting long-term price. However, concentration of ordering rights among large stakers may introduce governance and perception risks.
