The Ethereum Foundation's Ecosystem Support Program (ESP) awarded a combined $17,629,427 in grants during the first half of 2022, according to an allocation update the foundation published on September 7 of that year. The disbursements spanned client development, cryptography research, developer tooling, community education, and other areas. The publication date landed eight days before Ethereum completed its transition from proof-of-work to proof-of-stake consensus, a milestone known as The Merge, on September 15, 2022.

The first quarter accounted for $9.37 million of the total, with the second quarter contributing $8.26 million. Both figures represent a step up from the prior period: the ESP had distributed a combined $13.8 million across Q3 and Q4 of 2021, making the first-half 2022 total roughly 27.5% higher. The foundation's full-year spending across all programs reached approximately $105.4 million in 2022, with Layer 1 research and development representing the largest single category at $32.1 million, or about 30% of total outlays.

Several of the funded teams were directly responsible for running the software that executed The Merge. Sigma Prime received grants in both quarters: in Q1 for its Beacon Fuzz security testing work and in Q2 for the Lighthouse consensus client. Prysmatic Labs, the team behind the Prysm client, was funded in Q2. ChainSafe received support for its Lodestar client alongside work on the Web3.js developer library. Erigon and Nimbus each received funding for execution-layer client work. These are the software stacks that Ethereum node operators used to coordinate the network's transition to proof-of-stake. The Bellatrix upgrade, which prepared the consensus layer for The Merge, had activated on September 6, the day before the grant post went live.

Beyond client infrastructure, the two quarters included significant investment in zero-knowledge (ZK) cryptography, a field that allows one party to prove knowledge of information without revealing the information itself. ZK technology underpins a class of Ethereum scaling solutions called ZK rollups, which process transactions off the main chain and submit cryptographic validity proofs back to it. The foundation allocated roughly 7.2% of its 2022 total budget to applied ZK work. Recipients in this area included ZKHack, a zero-knowledge proof study group, along with MACI, RLN Anonymous Chat, and TLS Notary, among other projects focused on privacy and cryptographic infrastructure.

The grant rounds carried meaningful implications for builders outside North America and Western Europe. The Q1 allocation included funding for a university-level Ethereum development course at Universidad Simón Bolívar in Venezuela, a country with high rates of cryptocurrency use tied to chronic currency instability. The Q2 round funded Platzi Academy, a Latin American online education platform serving more than four million learners, to build out Spanish-language Ethereum developer curricula. Separately, BuidlGuidl received funding to build out its developer onboarding infrastructure, and grants for open-source tools including Web3.js and Sign-In with Ethereum are accessible to developers regardless of location. According to Electric Capital's 2022 developer report, approximately 71% of new smart contracts are first deployed on Ethereum, reflecting the network's continued draw for builders globally; the same report recorded more than 61,000 first-time code contributors to Ethereum in 2022 and a peak of approximately 26,500 active developers in June of that year. As of 2024, Nigeria accounts for roughly 3% of the world's blockchain developers, and Ethereum remains the most-used blockchain among African developers, according to the BitKE 2024 Developer Report sourced from Electric Capital's 2024 data.

The ESP describes its mandate as supporting free and open-source projects that contribute to Ethereum's public infrastructure, with an explicit policy against funding commercial ventures or token-incentive schemes. "ESP provides support to free and open-source projects that strengthen Ethereum's foundations, with a particular focus on builder tools, infrastructure, research, and public goods," the program states in its official documentation. That structure means grant outputs are broadly accessible rather than captured by any single commercial interest.

The trajectory established in the first half of 2022 has continued forward. By the third quarter of 2024, African organizations including Web3Bridge in Nigeria, Web3Clubs in Nairobi, Borderless Africa in Kenya, Danny Thomx in Rwanda, and the Africa Blockchain Institute in Benin had received ESP funding. A Q2 2024 grant also supported a ZK-based proof-of-ownership system designed around India's Aadhaar national identity infrastructure, a direct application of the cryptographic primitives the foundation was funding in these earlier rounds. In the foundation's framing of its long-term public-goods mission, the ZK investment from 2022 did not produce immediate consumer products; it seeded the technical groundwork that later grant rounds have begun to apply toward financial access in high-population, underbanked markets.
