There is never a dull year in the Ethereum ecosystem. As we begin 2025, we want to take the opportunity to look back at the progress that has been made across Optimism and beyond. From the many upgrades to the OP Stack, to partnerships and collaborations that were formed, to the millions in OP rewards and everything in between, the growth of the Superchain has been nothing short of exciting. 2024 has been a pivotal year in shaping the future of Ethereum and the user-owned internet – yet the work continues.

A milestone event took place during this year's Devcon – the Ethereum Interop Forum (EIF). This gathering brought together key players from across the Ethereum ecosystem who set aside competition to focus on a shared mission: making Ethereum truly interoperable.

As we step into 2025, we continue to summon Ether's Phoenix through the evolution of Retroactive Public Goods Funding. This post outlines our plan to improve the Retro Funding mechanism, as well as the proposed scope of contributions Retro Funding will reward in 2025, with the end goal of more effectively and accurately rewarding those creating the impact on the Superchain.

Interoperability is the key to achieving the Superchain vision, and it’s the central focus of the Optimism Collective’s roadmap for 2025.

Today we’re excited to welcome Kraken to the Superchain with Ink: a blockchain powered by the OP Stack.

With over 30 OP Chains in the Superchain ecosystem and nearly half of all L2 transactions taking place on the OP Stack, our community is bigger than ever and we're taking the opportunity to reintroduce the key pillars of the Optimism Collective.

Uniswap Labs, Uniswap Foundation, and Optimism are excited to announce Unichain, an L2 purpose-built for DeFi, exclusively on the OP Stack.

Today, every OP Chain in the Superchain operates under a standardized revenue sharing model,  ensuring all chains contribute fairly and equitably, with no exceptions or special treatment.

Today we are excited to welcome Soneium to the Superchain.
