Mainnet op-reth Migration

Low3.5

◆ Description

Celo Mainnet transitions from op-geth to op-reth on July 22, 2026. The op-reth release and migration documentation are live for node operators.

◆ Why it matters

Celo's mainnet switches its execution client from op-geth to op-reth on July 22, 2026, with documentation already available for node operators. This is a backend infrastructure migration with no effect on CELO's token mechanics, fee flows, or demand drivers. The event matters to operators running nodes, not to traders pricing the asset.
