Optimism released Upgrade 20 on September 25, introducing a multi-chain super root that combines multiple chain states into a single hash for improved cross-chain interoperability. This upgrade maintains separate dispute processes for each chain while accounting for dependencies between them.

A future hard fork will enable cross-chain message passing, expanding Optimism's ecosystem beyond its mainnet and securing about $17 billion across OP Stack chains as of August 2026.
