Ethereum layer 2 blockchain, Soneium, announced the upcoming upgrade to Soneium Minato, set to occur at the end of October. Granite and Fjord are planned to be introduced through a dual hard fork upgrade, along with an update of Soneium’s Layer 1 contract to version 1.6.0.
These upgrades aim to enhance the security and efficiency of the network, enabling Soneium Minato to integrate with the Superchain and expand its ecosystem alongside other Layer 2 networks on Optimism. Additionally, the upgrades will facilitate Superchain governance, allowing for the oversight of future Layer 1 contract updates and reinforcing the decentralization of Soneium’s ecosystem.
The Granite upgrade was proposed by Optimism in response to security vulnerabilities identified during a series of third-party audits conducted by Spearbit, Cantina, and Code4rena. This upgrade encompasses both a set of smart contract enhancements to address the vulnerabilities and a Layer 2 hard fork designed to improve the stability and performance of the fault-proof system. Key features of the Granite upgrade include limiting the input size for the bn256Pairing precompile and reducing the Channel Timeout.
On the other hand, the Fjord upgrade introduces the RIP-7212 precompile, which lowers gas costs for various smart wallet applications. It also implements FastLZ gas pricing to provide users with more predictable and optimized gas expenses, along with Brotli channel compression, which decreases data availability costs by approximately 5-15%.

Soneium: A Blockchain For Consumer-Grade Applications
Launched this summer by Sony’s blockchain division, Sony Block Solutions Labs, Soneium aims to connect blockchain technology with everyday internet services, thereby simplifying user onboarding into Web3.
Built on the Op Stack, the Soneium blockchain is designed to offer a “cost-effective development environment” for creating consumer-grade applications. Early adopters of the network include Optimism, Alchemy, The Graph, Chainlink, and the Astar Network.
Recently, Sony Block Solutions Labs partnered with stablecoin issuer Circle to integrate the Bridged USDC Standard into Soneium. This collaboration establishes bridged USDC as the primary token for value exchange within the platform, opening up new opportunities for both creators and users.
