Ethereum is closing out 2025 with some of the most structural upgrades we’ve seen since The Merge. Below is a breakdown of four major developments shaping the next era of Ethereum and L2 ecosystems, and why they matter for builders heading into 2026.

1. Ethereum L1 Scaling: Gas Limit Raised to 60 M

What changed

  • On 25 November 2025, validators increased the block gas limit from 45 M → 60 M.
  • This adds roughly 33 % more computation per block.

Immediate effects

  • Larger L2 batches and calldata.
  • Bigger contract interactions without hitting block limits.
  • A cleaner runway for upcoming data‑availability improvements.
  • Higher throughput for heavy dApps.

The change does not magically reduce fees, but it expands headroom during peak demand—especially for rollups.

Gas‑limit governance remains dynamic.

2. EIL: The Ethereum Interoperability Layer Is Here

Overview

The full architecture release of EIL (Ethereum Interoperability Layer) is arguably the most important UX shift since account abstraction. It lets wallets treat many rollups as a single unified environment.

Core capabilities

  • Seamless cross‑rollup operations
  • Atomic multi‑chain UserOps
  • One‑gas‑payment‑for‑everything
  • No bridging steps or chain switching required

Key components

  • Atomic Vouchers
  • Multi‑Chain Execution Engine
  • Cross‑Chain Gas Abstraction
  • Wallet Integration Layer

Current status

  • Public testnet spanning Sepolia and several L2s.
  • SDKs, bundlers, and documentation are available.
  • Still in R&D; not production‑ready.

Potential impact if adopted

  • Bridges become invisible.
  • Chain switching disappears.
  • Multi‑rollup apps feel “monolithic”.
  • Liquidity becomes more unified.

EIL aims to deliver the UX users have long wanted in a fragmented multi‑L2 world.

3. Arbitrum Orbit: Unified ARBOS Upgrade Guidelines

Why it matters

Running a custom rollup has historically been messy. The new unified ARBOS upgrade template standardizes the process for Orbit rollup operators.

Required upgrade parameters

  • Activation height or timestamp
  • Nitro version
  • Initialization parameters

All values are defined inside arbosOverride, ensuring every node in the rollup shares identical parameters.

Compatibility

Orbit chains must stay aligned with upstream Arbitrum releases, reducing the risk of unexpected breakage as the ecosystem expands with app‑specific rollups, gaming chains, and enterprise deployments.

Unified upgrade paths are now table stakes for any serious rollup operator.

4. Real‑World Identity Goes On‑Chain: Soneium × Sony IRC App

What it is

Sony’s L2, Soneium, launched the IRC App—a fan‑identity and engagement system powered by account abstraction.

Features

  • Connects with LINE, Google, Apple, X.
  • Converts social engagement and sentiment into an on‑chain fan score.
  • Issues membership ranks (Regular → Gold) that unlock perks such as ticket access, events, and voting rights.
  • Provides a fully gasless onboarding experience—no wallet setup needed; AA handles everything.

Significance

This is a clear real‑world example of Web3 identity used for:

  • Membership
  • Reputation
  • Culture
  • Entertainment
  • Community‑building

It demonstrates that Web3 identity can move beyond DeFi and speculation into mainstream consumer applications.

5. What This Signals for 2026 (Builder Perspective)

  • Multichain UX is finally advancing; EIL could make L2 fragmentation a historical footnote.
  • Rollup infrastructure becomes safer with unified ARBOS templates, lowering operational risk.
  • Ethereum L1 now has more headroom—60 M gas benefits both rollups and heavy dApps.
  • On‑chain identity is heading mainstream; Soneium’s IRC app offers a blueprint for consumer adoption.
  • New dApp categories become viable: cross‑rollup DeFi, loyalty apps, fan‑engagement tools, and identity‑driven platforms.

Conclusion

Late 2025 isn’t just a batch of updates—it’s a turning point. Ethereum is evolving into a platform with:

  • Unified infrastructure
  • Seamless multi‑chain UX
  • Safer rollup operations
  • Real‑world identity adoption

If you’re building in 2026, these upgrades are not optional. Now is the moment to adapt, experiment, and ship.
