ZKsync's New Funding Path: The Ethereum Ecosystem Rollup Framework

The Ethereum Foundation has shifted from an open grant model to a targeted funding approach, announcing a collaborative ZK grant round with Aztec, Polygon, Scroll, and Taiko. This marks a strategic pivot where the foundation now proactively funds projects aligned with near-term priorities like scaling and interoperability, rather than reviewing a constant stream of applications pausing open submissions. The framework pools 900,000 USD from the participating rollups, with winners selected through a curated process to advance zero-knowledge proofs.

This provides a direct funding channel for ZKsync, complementing its existing capital strength. The company recently raised $458 million in a capital raise, and this new framework offers a steady, strategic source of funding for foundational ZK research. It aligns with the foundation's new model of funding initiatives that strengthen Ethereum's position, moving away from the previous open application system that had become overwhelming.

The framework's focus on advancing zero-knowledge proofs directly supports ZKsync's core technology. By funding projects that improve the efficiency, security, and applicability of ZK proofs, the initiative aims to benefit the entire ecosystem. This could drive traffic and fee revenue to the zkSync Era platform as its underlying technology matures and becomes more widely adopted.

The Funding Shift: From Open Grants to Strategic Pools

The Ethereum Foundation's funding model has fundamentally changed. After distributing $32.6 million in Q1 2025, the foundation admitted it had limited capacity to pursue new strategic opportunities due to overwhelming demand under its open grant program. It has now paused open submissions and is moving toward a curated, strategic approach. This means funding is no longer a passive application process but an active pursuit of projects aligned with the foundation's defined priorities.

For ZKsync, this shift means a new competitive landscape. The company must now vie for capital within strategic pools, like the recent $900,000 collaborative ZK grant round it won. This win is a direct result of aligning with the foundation's current focus on zero-knowledge proofs. However, the new model prioritizes projects that advance the broader Ethereum ecosystem's roadmap, which is now centered on L1 scaling, usability, and base layer security for 2026.

This creates a potential tension. While ZKsync benefits from funding for foundational ZK research, the model may limit support for pure rollup infrastructure or user-facing tooling that doesn't directly feed into the EF's top-tier tracks. The strategic funding is a powerful resource, but it also means ZKsync must continuously demonstrate how its work fits into the foundation's specific 2026 priorities to secure ongoing capital.

The Rollup Reality: Migration Costs and Platform Focus

ZKsync is executing a deliberate platform consolidation in 2026. The company has announced a planned, orderly sunset of its legacy ZKsync Lite rollup, a system launched in 2020 that served as a foundational proof of concept. This deprecation redirects engineering resources from a legacy, non-smart contract system toward its core zkSync Era platform, which is a fully functional zkEVM.

This migration creates a direct cost and friction for users, as it requires moving funds and applications from the older system. However, the strategic benefit is clear: it consolidates development focus on a single, more advanced, and fee-generating system. With ZKsync Lite processing fewer than 200 transactions daily and holding roughly $50 million in user funds, the pivot is a rational move to streamline operations and accelerate innovation on the primary platform.

The company's prior $200 million Series C funding provides a crucial financial buffer to support this strategic pivot. That capital, part of a total $458 million raised, was explicitly earmarked for ecosystem development and team growth. This financial strength allows ZKsync to manage the user migration process and fund the engineering work needed to solidify zkSync Era, ensuring the platform is well-positioned to leverage new funding from initiatives like the Ethereum Foundation's collaborative grant framework.
