This page outlines the breaking changes that will impact Soneium Minato node operators, developers, and users.

Fjord and Granite Upgrade

The upgrade will take place on October 28, 2024.

Following the recent rollout of the Ecotone upgrade to Soneium Minato, which included the Dencun upgrade from Ethereum mainnet and adopted EIP-4844 blobs for data availability, this is now the second upgrade for Soneium Minato. This upgrade will port Soneium Minato to Granite, the latest version of the Optimism OP stack, paving the way for Soneium's integration into the Superchain. Notably, this upgrade combines two network upgrades: Fjord and Granite.

The most important upgrades include:

• The introduction of the RIP-7212 precompile to reduce gas costs for many smart wallet applications.
• Support for Brotli batch compression, which results in approximately 5-15% lower data availability costs, while also improving the robustness of L1 data pricing.
• An increase to the max-sequencer-drift parameter, now hardcoded to give chain operators more time to respond to L1 node issues without risking a potential L2 chain halt.

A full description of the upgrade is available on Optimism governance and documentation:
