Why Interoperability Funding Matters Now
Ethereum’s next chapter depends not just on scaling, but on staying connected. As rollups, L2s, and app-specific chains proliferate, the ecosystem risks splintering into isolated silos of data, liquidity, and governance. The Interop Standards, Infrastructure & Analytics domain was created to counter this drift by funding the open standards, analytics, and coordination tools that keep Ethereum transparent and interoperable. Read more on this here.
The Many Meanings of Interop
Interoperability isn’t one thing. It’s a spectrum, from protocols that let chains talk to each other, to data and governance systems that help people coordinate across them. The GG24 Interop Standards, Infra & Analytics domain funds projects across five layers of this spectrum.
- Protocol layer projects push the boundaries of cross‑chain execution and privacy. They build the core plumbing that treats many chains as one network.
- Infrastructure layer projects create standardized tools, SDKs and gateways that make adoption of interoperable frameworks easier for builders.
- Data layer projects generate and open up metrics about chain usage, impact and adoption, turning raw activity into evidence.
- Governance layer projects define shared schemas and plural funding designs so that decisions, credentials and impact attestations can interoperate.
- Funding layer projects show how interoperable data and standards unlock new funding models for social, climate and open‑source initiatives.
From Layers to Builders: Mapping the Interop Landscape
If the five layers of interoperability show how Ethereum evolves, from cross-chain protocols to data, governance, and funding, then this next section shows who is building those layers today. Each accepted project strengthens one or more rungs of that ladder: some are deep in protocol plumbing, others in the analytics and coordination layers that make those systems visible and trustworthy.
Our eligibility decisions followed that layered logic, rewarding projects closest to interoperability standards at the core, while still nurturing the open-data and research infrastructure that will make future OIF adoption measurable, auditable, and fundable.

What Comes Next — Shaping Interoperability Together
As this round unfolds, we’re not only funding projects, we’re shaping how interoperability itself is understood, measured, and sustained.
The five dimensions outlined here, protocol, infrastructure, data, governance, and funding, form our current working model. But they’re not final. Interoperability is a moving frontier, and its true shape will emerge only through collective exploration.
We invite builders, researchers, and funders to weigh in:
- Do these dimensions reflect where coordination gaps really lie?
- Which areas deserve dedicated sub-rounds or deeper investment?
- What new kinds of data or metrics would make progress more visible?
Your input will help evolve this domain into a shared, transparent map of Ethereum’s multi-chain ecosystem, one that guides not just how we fund, but how we coordinate.
