The Ethereum Foundation's Ecosystem Support Program allocated nearly $14 million to open-source projects, research teams, and community builders during the second half of 2021, with a combined total of $13,829,000 spanning grants across seven categories. The foundation published the disclosure on February 15, 2022, covering a six-month window when ETH hit its all-time price high and core developers were accelerating work toward the network's transition to proof-of-stake. Individual grant amounts are not publicly broken out in the foundation's standard allocation disclosures.

The grants are split unevenly across the two quarters. Q3 2021 accounted for $2,992,000, roughly 22 percent of the combined total. Q4 2021 carried the remaining $10,837,000, reflecting a significant ramp-up in funding as the foundation pushed resources toward client teams and cryptographic research tied to the upcoming Merge. According to the foundation's 2021 annual report, Ethereum Foundation spending across the full year 2021 totaled $48 million, with $19.6 million in grants across all programs and $21.8 million directed to Layer 1 research and development.

Merge Preparation Drove Q4 Spending

The heaviest concentration of Q4 funding went to teams building or maintaining Ethereum consensus layer clients. Sigma Prime (Lighthouse), ChainSafe (Lodestar), and Prysmatic Labs (Prysm) all received grants during the quarter. These three client implementations are central to the validator network that runs alongside Ethereum's execution layer, and all three needed to be Merge-ready before the Kiln testnet launched in early 2022.

Cryptography research received significant attention as well. The foundation funded zkEVM work led by Ying Tong Lai in collaboration with Electric Coin Company, alongside zero-knowledge proof tooling for identity and voting applications. L2BEAT, the analytics platform that tracks capital deposited across Ethereum Layer 2 networks, also received support during this period. L2BEAT was built to provide transparent, independently verifiable data on Layer 2 systems. The platform has since become a standard reference for the rollup ecosystem, eventually monitoring more than $10 billion in total value locked across more than 30 projects.

The Q3 cohort leaned toward developer tooling and execution layer maintenance. ChainSafe also received a separate grant to maintain the Web3.js library, one of the most widely used JavaScript interfaces for Ethereum. Brazilian developer Victor Maia received funding for an Ethereum cryptography module for the Kind programming language. Hyperledger Besu and OpenEthereum, both alternative execution clients, received support for ongoing maintenance work.

Terminology Shift Carries Real Consequences for Global Developers

The allocation update appeared roughly three weeks after the Ethereum Foundation published what it called "The Great Renaming," a formal announcement retiring the Eth1 and Eth2 labels in favor of "Execution Layer" and "Consensus Layer." The foundation cited two main problems with the old terminology. First, scammers had been instructing users to exchange their ETH for a fictitious ETH2 token. Second, the two-name framing implied a complete chain replacement when the actual upgrade involved two co-existing layers merging into a unified system.

"Eth1 is now the execution layer. Eth2 is now the consensus layer. Together they form Ethereum," the foundation wrote in the January 2022 post. "The Eth2 terminology has been abandoned for several reasons... most critically, it created a broken mental model for new users."

The practical impact extends beyond English-speaking markets. As a recognized consequence of the change, any developer who had built courses, documentation, or training materials around the Eth2 framing faced the task of updating those resources. Community education programs in non-English-speaking regions, including those in Nigeria, Nepal, and Colombia, were among those navigating added cost and complexity while operating on limited budgets.

Community Grants Reached Lagos and Kathmandu

Two community grants stand out for their geographic reach. Web3 Lagos, a Nigerian organization that has trained more than 2,000 people in Web2 and Web3 blockchain development at no cost, received support to run what is described as Nigeria's primary Ethereum-focused conference. The grant arrived during a period of severe regulatory pressure: the Central Bank of Nigeria had issued a directive in February 2021 barring banks from processing cryptocurrency transactions, pushing most Nigerian crypto activity into peer-to-peer markets. By 2023, Nigeria's P2P crypto volume had reached an estimated $17 billion annually, underscoring the scale of demand that existed even under those constraints. For local builders operating without domestic institutional support, the grant represented external recognition from one of the ecosystem's primary funding bodies.

In Nepal, the foundation funded the eSatya Blockchain Fellowship, a 12-week mentorship program covering Bitcoin, Ethereum, smart contracts, decentralized applications, distributed ledger fundamentals, and other related topics. Nepal operates without a clear legal framework for cryptocurrency, but no outright ban is in place. India, Nepal's dominant regional neighbor, was debating a crypto prohibition for much of 2021 and 2022, making cross-border developer training pipelines more strategically relevant than they might appear at first glance.

Latin American community groups in Cuba, Honduras, and Colombia also received small-scale education grants. Cuba's near-total exclusion from the US-led banking system makes Ethereum one of the few functional tools for international transfers available to residents. Honduras and Colombia present different but related dynamics: both countries rely heavily on international remittances and have experienced significant currency volatility, conditions that have driven sustained interest in decentralized financial tools.

What Comes Next

The Q3 and Q4 2021 period sits at the peak of Ethereum's bull market cycle. ETH reached $4,815 on November 9, 2021, before declining sharply through 2022. The Merge itself completed in September 2022, as documented on ethereum.org, a milestone that reflects the scale of client and research investment visible in the Q4 2021 grant data. Future ESP allocation updates are expected to show how funding priorities shifted once the Merge was complete and the foundation turned its attention toward scaling through rollups and further cryptographic improvements. The absence of grants to India, East Africa, and Francophone West Africa in this cycle remains a gap worth tracking as application infrastructure and community organization in those regions continues to develop.
