Optimism
Optimism is the most widely deployed Ethereum L2 stack — the OP Stack — which now underpins Base (Coinbase), Worldchain (World), Zora Network, and 30+ other L2s in the Superchain ecosystem. The design's collective security model is a major departure from single-chain L2 economics.
The Retroactive Public Goods Funding mechanism, pioneered by the Optimism Collective, has distributed over $80M to open-source builders and become a widely-studied template for public-goods funding in the industry.
The 2026 fault-proof rollout completed the last technical milestone for full production-grade decentralization of the Optimism stack, giving the ecosystem a durable trust story.
The most widely adopted L2 stack. We backed the Series A on the conviction that the Superchain design creates real network effects.

“The Superchain is the closest thing crypto has to a coherent multi-chain product strategy.”
