The latest version 0.4.25 release of Solidity fixes two important bugs. Another important bug has already been fixed in version 0.4.22 but it was only discovered recently that the bug existed. Note that the Ethereum Foundation runs a bounty program for the code generator part of Solidity. Cleanup of Exponent in Exponentiation Likelihood of occurrence: very lowExploitability: highDiscoverability by tests: lowFixed in version: 0.4.25 Summary: Using short types in the exponent of an exponentiation operation can lead to invalid results. The Solidity language allows integer types that are shorter than 256 bits, even though the Ethereum Virtual Machine only knows…

Greetings from the Ethereum Foundation Grants Team! As we go full steam ahead to Devcon 4, we’re back to announce Wave 4 of the Grants Program! Thank you to all the fantastic community members that have applied with creative ideas on how to bolster our ecosystem. We would not exist without the time and energy that you put into Ethereum. While the program continues to grow, we will increasingly continue to involve more community members in the decision making process. The Grants Program today is vastly improved from just earlier this year, thanks to all the helpful feedback from the…

Přátelé, Today, we’re excited to unveil our Devcon4 Sponsors. Each of this year’s six tiers of sponsorship is supporting the Foundation’s work in significant and impactful ways. We’re thrilled to involve many major and growing teams in Devcon, and to make the most of this opportunity to support the Foundation’s core mission. To this end, we’re proud to first announce this year’s premier Devcon supporters: SERENITY: AdEx, BlockAsset Ventures, Blockchains LLC, Blockfolio, Colony, ConsenSys, OmiseGO, Sparkpool, and Status METROPOLIS: Celer Network, Kyber Network, imToken, Santiment, and ShapeShift HOMESTEAD: Ernst & Young, FunFair, Golem, Microsoft, MyEtherWallet, SingularDTV, and Wanxiang Blockchain Labs…

Our goal on the grants team is to be faithful stewards of Ethereum community resources. As part of the Ethereum Foundation’s ongoing effort to diffuse power throughout our community, we give grants that we believe will return the highest impact on the Ethereum ecosystem over the long-term. What is the scope of EF grants? Open source! Funding is only for future work Avoid playing favorites.  We try not to advantage one team over others Avoid grants at the application layer, though we do believe that projects and teams working at the application layer should apply when they are building open…

The Funding Coordination team is excited to announce a joint initiative with Keyring Network that introduces a new approach to impact funding in the Ethereum ecosystem. Directly support privacy-focused developers Keyring’s zkVerified permissioned vaults on mainnet provide compliant and privacy-preserving access to DeFi lending markets. For the first two months, all protocol fees from Keyring’s zkVerified vaults will go to the legal defense funds of Roman Storm and Alexey Pertsev, the Tornado Cash developers currently on trial for publishing open-source code. This model ensures that the first users of a vault directly support the legal protection of privacy-focused developers. By…

The Ethereum Foundation has opened applications for the 2026 Internship Program: a paid, full-time opportunity to work directly with teams advancing the Ethereum protocol and ecosystem. Interns will join EF teams for 12 weeks over the summer, contributing to active R&D and ecosystem-oriented projects across a wide range of focus areas. The internship is open to candidates worldwide and can be completed remotely or from EF’s offices. A summer meetup will bring the cohort together to connect in person. The Goal Ethereum continues to evolve; each upgrade, research initiative, and experiment depends on people willing to dive into complex problems…

tl;dr: Over the last couple of days, some L2s noticed that their deployments on Sepolia didn’t work properly anymore. This is due to EIP-7594 which changes the format for proofs. In anticipation of Fusaka, we urge all blob originators to update their software to create Cell Proofs instead of blob proofs. Background One underdiscussed aspect of EIP-7594 (PeerDAS) is that it changes the format for proofs from blob proofs to cell proofs. This allows for downloading a specific part of the blob instead of the whole blob for data availability sampling. This change might break user applications that send blob…

Starting with the upcoming Fusaka hard fork, EIP-7825 introduces a per-transaction gas limit cap of 2²⁴ (≈ 16.78 million gas). This change is already live on Holesky and Sepolia, and will activate on mainnet with Fusaka. Developers and users who rely on very large transactions should verify that their contracts and transaction builders conform to the new cap. Background As Ethereum scales to higher block gas limits and prepares for parallel execution (e.g. EIP-7928 in Glamsterdam), the Fusaka fork introduces a per-transaction gas limit cap. Previously, a single transaction could consume the entire block gas limit (~45 million gas), creating…

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…
