Ethereum Ecosystem — 2026-03-25
The Ethereum Foundation made headlines this week with a major strategic pivot, elevating Layer 1 development after years of prioritizing L2 rollups, while simultaneously redefining how L1 and L2 roles interact across the ecosystem. On the DeFi front, Balancer faced a critical $110M hack that prompted a full protocol overhaul and governance restructuring, while Mellow Protocol's TVL surged past $300M amid airdrop excitement. L2 data remains accessible on L2BEAT, though current 7-day change figures require direct verification at source.
Ethereum Ecosystem — 2026-03-25
Protocol & Upgrade Tracker

-
Ethereum Foundation Pivots Back to L1: The Ethereum Foundation is shifting its scaling strategy, elevating Layer 1 development after years of prioritizing L2 rollups. The move signals a renewed focus on base-layer improvements and a rebalancing of resources between L1 and L2 priorities.
-
EF Redefines L1 and L2 Roles in 2026 Vision: Alongside the strategy shift, the Ethereum Foundation has outlined a new ecosystem vision that focuses on scaling, security standards, and fixing cross-chain fragmentation. The updated guidance clarifies how base-layer and rollup responsibilities are expected to evolve together going forward.

- Glamsterdam and Hegotá on 2026 Roadmap: Ethereum enters 2026 with a structured upgrade roadmap featuring two major hard forks planned for the year — Glamsterdam (expected H1 2026) and Hegotá. Glamsterdam is poised to improve censorship resistance, MEV transparency, and user experience, while Hegotá anchors the medium-term roadmap focused on interoperability, privacy, and rollup maturity.
L2 Rollup Landscape
L2BEAT tracks total value secured (TVS) across all Ethereum rollups. The table below reflects the current state of the top L2 networks; for live 7-day change figures, verify directly at .
| L2 | TVL | 7d Change | Notable Development |
|---|---|---|---|
| Arbitrum One | See L2BEAT | Verify on-chain | Non-emergency upgrades go through an 8-day delay on L2 and 3-day delay on L1, giving users 10 days to exit |
| (All L2s) | Verify at L2BEAT | — | EF's new strategy elevates L1 while clarifying L2's scaling role |
Note: Specific TVL figures and 7-day change data for individual L2s were not available with confirmed accuracy in this research cycle. Readers should check and directly for up-to-date numbers.
DeFi & dApp Activity

- Balancer: $110M Hack Triggers Protocol Overhaul: Balancer shut down following a devastating $110 million exploit. In the aftermath, the DeFi protocol pivoted to a "DAO-first" future, launching a governance overhaul intended to restructure how the protocol is managed and secured going forward.

-
Mellow Protocol TVL Surges Past $300M: Mellow Protocol, a Lido-allied restaking platform, saw its total value locked surge past $300 million this week. The growth has been driven by a combination of institutional "Core Vaults" and aggressive airdrop farming activity, positioning it as one of the fastest-growing restaking protocols in the ecosystem.
-
dApp Architecture in 2026 — Modular vs. Monolithic: A comprehensive guide to dApp architecture practices in 2026 highlights real trade-offs between modular and monolithic approaches, L1 vs. L2 vs. app-chain deployment choices, and growing adoption of Account Abstraction. The report reflects a broader ecosystem maturation as developers weigh indexing strategies and stack flexibility.
What to Watch Next Week
-
Glamsterdam Upgrade Progress: Watch for any new EIP inclusions or core dev call updates as the Ethereum Foundation refines the Glamsterdam upgrade expected in H1 2026. Key areas to track include proposals for censorship resistance and MEV improvements.
-
Balancer DAO Governance Vote: Following the $110M hack and announced overhaul, Balancer's community is expected to move toward formal governance votes on the protocol's restructured DAO-first model. Monitor Balancer governance forums for proposal timelines.
-
Mellow Protocol Airdrop Developments: With Mellow Protocol's TVL crossing $300M and airdrop speculation intensifying, watch for any official airdrop announcements or eligibility snapshots from the Lido-backed restaking protocol.
-
EF L1/L2 Strategy Details: The Ethereum Foundation's newly announced strategy pivot deserves close attention. Watch for follow-up technical posts, AllCoreDevs call updates, or EIP proposals that reflect the foundation's new focus on base-layer development.
Reader Action Items
- Check Balancer governance forums for official proposals related to the post-hack DAO restructuring — community participation in the overhaul vote may directly shape the protocol's future direction.
- Verify L2 TVL live data at and for up-to-date figures on Arbitrum, Optimism, Base, and other rollups following the EF's new L1/L2 strategy announcement.
