As previously announced, the Holešky testnet has reached its planned end-of-life date and will be sunset shortly. The vast majority of remaining validator nodes will be shut down 2 weeks after the Fusaka upgrade has finalized on Holešky. After this, Holešky will no longer be supported by client, testing or infrastructure teams. Following the launch of the Hoodi testnet in March 2025, infrastructure providers and staking operators have had the opportunity to migrate their testing operations. Background Holešky was launched in 2023 as Ethereum’s largest public testnet, designed specifically for testing staking infrastructure and validator operations at scale. The network…

Over the past few years, the Ethereum ecosystem has grown in depth, diversity, and maturity. Builders and communities worldwide have pushed the boundaries of what’s possible, creating new tools, protocols, and public goods that strengthen the network as a whole. As the ecosystem grows, our approach to supporting it must adapt as well. Today, we’re excited to share the next step in that journey: the Ecosystem Support Program’s (ESP) new grants program. This announcement builds on our earlier update, where we temporarily paused open grant applications to reassess our priorities and funding approach. During this time, we focused on designing…

In two weeks, we open the doors to the first-ever Ethereum World’s Fair at La Rural in Buenos Aires. This year isn’t about someday. It’s about now. On Ethereum today you can pay, play, vote, save, borrow, lend, and chat, all onchain — and at Devconnect you’ll experience that shift hands-on, IRL.Buenos Aires is the right backdrop for this moment: a city where crypto is part of daily life and where builders are ready to show what’s live. Below is your guide to what’s inside the fairgrounds, how to plan your week, and what to do before you arrive. Inside…

Fusaka follows this year’s Pectra upgrade, representing a major step forward in Ethereum’s scaling roadmap that improves L1 performance, increases blob throughput, and enhances user experience. The Fusaka network upgrade is scheduled to activate on the Ethereum mainnet at slot 13,164,544 (December 3, 2025, 21:49:11 UTC). Fusaka also introduces Blob Parameter Only (BPO) forks to safely scale blob throughput after PeerDAS activation. These are minimal, config-only upgrades that adjust the blob target/max and fee update fraction. See the activation table below for further details. The Fusaka mainnet client releases are listed below. Fusaka Overview Fusaka’s headlining feature is PeerDAS (Peer…

Ethereum’s weekly All Core Developer calls are a lot to keep up with, so this “Checkpoint” series aims for high-level updates roughly every 4-6 weeks, depending on what’s happening in core development. See the previous update here. If you enjoy reading core development updates, you may also be keen to learn that Forkcast now publishes call summaries, chats and transcripts for each All Core Devs call, usually available within a couple hours of the call. tl;dr: The Fusaka upgrade is nearly out the door, Glamsterdam is ramping up, with its major features in implementation and minor features being decided on.…

Disclaimer: The following blog is a proposal from the Account Abstraction team. Content may not imply consensus views, and the EF is a broad organization that includes a healthy diversity of opinion across Protocol and beyond that together strengthen Ethereum. Since the early days of Ethereum, the promise has always been bold: a global, permissionless, censorship-resistant computing platform. Today, that promise is more alive than ever. Ethereum has scaled through rollups, where blockspace is abundant and transactions are cheap. The challenge now is not just throughput, but seamless user experience across that multichain horizon. What if all the L2s felt…

In late 2024, the Ethereum Foundation, together with Secureum, The Red Guild, and Security Alliance (SEAL), launched the ETH Rangers Program, an initiative to provide stipends for individuals doing public goods security work in the Ethereum ecosystem. The goal of the program was straightforward: to fund independent efforts that enhance the resilience of the Ethereum ecosystem, and to recognize people with demonstrated track records of meaningful contributions to important security work that benefits Ethereum as a whole. Now that the six month ETH Rangers Program has wrapped up, we want to share the outcomes of the 17 stipend recipients’ work.…

Funds were split between two wallets holding $3.3 million and $880,000. The exploit involved MEV-linked addresses and preemptive transaction timing. MakinaFi has not released a technical statement or mitigation plan. A major crypto breach has struck MakinaFi, draining millions in Ethereum from the decentralised finance platform. The incident resulted in the loss of 1,299 ETH, valued at roughly $4.13 million at the time of the attack. PeckShieldAlert flagged the theft on X, where it traced the movement of the stolen assets across Ethereum wallets. The breach quickly gained traction online as blockchain analysts and on-chain trackers pieced together the flow…

Ethereum (ETH) holds near $3,000 as institutions accumulate despite mixed short-term sentiment. Strong staking, wallet growth, and ETF inflows support Ethereum’s price floor. ERC-8004 could unlock AI-driven on-chain demand and long-term ETH value. Ethereum is entering a pivotal phase as price action, institutional flows, and protocol-level innovation begin to converge. After a volatile start to the year, ETH has reclaimed the $3,000 level, signalling renewed confidence among both traders and long-term holders. At the time of writing, Ethereum is trading near $3,010, with a market capitalisation of roughly $364 billion and a 24-hour trading range between $2,899 and $3,028. This…

Ethereum price falls to $2,325 on profit-taking after rising to $2,416. The repeated rejection at $2,360–$2,400 resistance weakens the overall momentum. Breaking below the key support at $2,312 could send ETH toward $2,173. After a rally that pushed Ethereum close to $2,416, things quickly changed, and now ETH sits around $2,325. This sharp drop near $2,400 tells us a lot about where Ethereum’s headed next, at least for now. Pushback at $2,416 resistance Ethereum (ETH) initially surged about 10% in a sharp move that triggered liquidations and brought renewed attention to the token. After reaching around $2,416, momentum slowed, and…
