We’re officially counting down to Ethereum’s biggest upgrade yet, Fusaka! Landing on December 3rd, Fusaka brings meaningful improvements that will be felt across the entire ecosystem from everyday users to builders, L2s, and more! Here’s what to expect: ✅ Faster, cheaper, smoother UX ✅ Improved cross-chain user experiences ✅ Lower L1 + L2 transaction fees — more efficient gas markets and better scalability And much more!

Ethereum’s next major upgrade, Fusaka (Fulu + Osaka), is landing next week. 🚀 EIP-7607: https://lnkd.in/e-ThNGkc How do Ethereum upgrades work? Because the chain never stops, upgrades happen “in flight”: • Client teams ship new versions that support the upcoming rules. • Node operators and validators upgrade their clients ahead of time. • At a specific activation time, the network starts enforcing the new rules. • As long as the majority has upgraded, the chain hard forks onto the new consensus rules and keeps running smoothly. What’s in Fusaka? The theme of Fusaka is more scalability on L1 and better foundations for data: • ~33% gas limit increase – more computation and transactions per block. • Stronger support for transient data storage – setting the stage for future data-heavy workloads. • PeerDAS (Peer Data Availability Sampling) – the headliner feature that brings a sharding-like model to Ethereum’s data. With PeerDAS, not all nodes are required to store all blob data. Lighter nodes can run with lower hardware requirements, while operators that can handle more load opt in to holding more data and push the network to new capacity levels. This is a big unlock for rollups and a key step on the path to full danksharding. My coworker Emmanuel NALEPA put together a great primer on PeerDAS: https://peerdas.net If you run validators, nodes, or infra, now is the time to upgrade your clients ahead of activation.

What does true interoperability look like? It’s not just about connecting chains, it’s about making it seamless for everyone to build and use. ⚙️ Seamless — simple for all developers to plug in ⚡ Fast — crosschain swaps and transfers in under 3 seconds 🌐 Open — accessible to all EVM chains 🔒 Trustless — no centralized systems This is what we’re building with the Universal Intents Engine, bringing frictionless interop to life, one intent at a time. Read more about it below! https://lnkd.in/ez8abSBJ

Was an honor to talk about Arbitrum Everywhere last night at the NYSE. It’s a new era for crypto and capital markets. Thank you for having us!

How can #blockchain technology scale payments? Online payments have come a long way — from credit cards to digital wallets to instant transfers. Now, blockchain technology is adding a new layer of scalability, efficiency, and programmability to the mix. By leveraging blockchain platforms like Arbitrum, businesses can complement existing payment rails with: ⚡ Faster Settlement: Transactions finalize in milliseconds, improving real-time commerce and user experience. 💵 Lower Costs: Efficient, high-throughput infrastructure enables micro and cross-border payments at scale. 🌍 Global Reach: Blockchain operates 24/7, making global transactions as seamless as local ones. 🧩 Programmable Logic: Payments can include built-in rules for refunds, revenue splits, or loyalty rewards. 🔒 Transparent Security: Cryptographic proofs and on-chain records ensure trust and auditability. Blockchain isn’t here to replace the payment systems we know — it’s here to extend and scale them, bringing faster, more global, and programmable capabilities to the digital economy.

From Friction to Fintech: Glider's Strategic Move to Account Abstraction The problem for consumer-grade crypto is clear: If a user's first experience is fumbling with gas tokens and private keys, they're gone. Glider (cross-chain portfolio manager) recognized this friction wasn't just a bug, it was a business blocker. They needed the smoothness of a traditional financial app without compromising on non-custodial security. The answer wasn't building in-house for months — it was leveraging ZeroDev. Key Takeaways for Builders: Invisible UX is the New Benchmark: ZeroDev's Kernel smart wallets and Paymaster enabled invisible gas and instant wallet creation. For users, complexity truly fades into the background. Automation via Permissions: The session key framework is the engine for Glider's automated portfolio management, allowing trades and rebalancing in the background, non-custodially. Engineering ROI: As Co-founder Brian Huang notes: “ZeroDev gave us production-ready infrastructure from day one,” freeing up months of engineering time to focus on core product features, not wallet plumbing. This case study demonstrates that for teams serious about mainstream adoption, Account Abstraction isn't a feature, it's the foundation. Stop reinventing the wallet — start building the product.

How Blockchain can scale finance applications? For decades, financial institutions have driven innovation in how people move, store, and grow capital. But as digital finance expands across borders and industries, scalability, interoperability, and transparency are becoming the new competitive advantages. Blockchain technology offers a pathway to scale, not by replacing traditional finance, but by enhancing it. By leveraging blockchain technologies like Arbitrum, banks and fintechs can: - Settle transactions instantly, across networks. - Unlock programmable assets, from tokenized deposits to real-world assets. - Enable interoperability between traditional systems and emerging digital markets. The result isn’t disruption, it’s transformation. A financial system that’s faster, more inclusive and more programmable, built in collaboration with the institutions that already form its backbone.
