Ethereum Foundation put $5.5M into Q2 grants, most of it into ZK

The Ethereum Foundation awarded $5,502,930.20 in grants during the second quarter of 2026, according to its own quarterly allocation report, published on August 18. The report doesn't include a year-over-year comparison or treasury runway figures, but the category breakdown makes the Foundation's current priorities fairly explicit.

Zero-knowledge proving pulled in the heaviest concentration of funding. Multiple teams — Brevis, Succinct Labs, SilentSig, and Matter Labs among them — received grants tied to moving layer-1 block proving onto on-premise, multi-GPU hardware rather than relying purely on cloud infrastructure, alongside separate grants for zkVM research and polynomial optimization work. Protocol-level funding went toward client development across Lighthouse, Lodestar, Ream, and Gean, plus consensus mechanism work and formal specification efforts, while a dedicated security track funded execution-layer and consensus-layer vulnerability research specifically framed around hardening the network ahead of the Glamsterdam upgrade.

• Total Q2 2026 grants: $5,502,930.20
• Zero-knowledge proving hardware: Brevis, Succinct Labs, SilentSig, Matter Labs, among others
• Client development funded across Lighthouse, Lodestar, Ream, and Gean
• Dedicated security research track tied to Glamsterdam hardening
• Cryptography grants covered post-quantum signature schemes and formal verification

Smaller allocations rounded out the rest: developer tooling grants for projects like a JVM integration for web3j and a Noir-to-LLZK compiler, application-infrastructure funding for private-read and transaction-indexing tools, privacy work through the Open Anonymity Project and Kohaku wallet integration, and a cluster of ecosystem grants covering internship programs and academic partnerships as far afield as Hong Kong Polytechnic, institutions in Mindanao, and a residency program in Bhutan. The security-heavy framing of this quarter's grants lines up with the Foundation's own recent moves — it added a dedicated cybersecurity specialist to its board earlier this month, a step that followed a 40% cut to its own operating budget rather than preceding it. Funding security research specifically around Glamsterdam's public testnet also tracks with where the network's actual near-term risk sits: an upgrade this central to Ethereum's execution model is exactly the kind of change that benefits most from adversarial scrutiny before it reaches mainnet, and that's where a meaningful share of this quarter's money went.

None of this is a one-off pattern for the Foundation. Its grant reports have leaned toward zero-knowledge infrastructure and client diversity for several quarters running now, reflecting a broader roadmap priority: reducing how much of the network's proving and validating work depends on any single client implementation or a narrow set of proving providers, since either kind of concentration becomes a single point of failure at scale. The academic and internship grants scattered through the ecosystem category serve a slower-moving version of the same goal, seeding the next generation of protocol researchers and client developers well before any specific upgrade needs them, rather than scrambling to recruit expertise only once a deadline is already close. None of the money in this report is discretionary in the sense of funding Ethereum's own core team directly — it flows to outside teams and independent researchers, which is also why the category breakdown doubles as a fairly honest map of where the Foundation thinks the ecosystem's own capacity is thinnest.
