Swap wETH to Mantle’s mETH from major chains in under 60 seconds. No traditional bridges, slippage, or complex onboarding steps required. Netting + rebalancing cuts liquidity fragmentation and operational costs. The blockchain industry’s liquidity fragmentation problem has a new solution. Everclear, the interoperability protocol formerly known as Connext, has launched cross-chain asset settlement on Mantle Network. The partnership will allow users to convert wrapped Ethereum (wETH) from major chains including Ethereum, Arbitrum, Base, and Polygon directly into Mantle’s mETH token in under 60 seconds. The integration bypasses traditional bridging entirely, marking a significant infrastructure breakthrough for decentralized finance adoption.​ The…

CCA runs fully on-chain auctions that clear bids block by block for gradual price discovery. After auctions end, liquidity is automatically added to a Uniswap v4 pool at the final cleared price. The model aims to reduce sniping, front-running, and bundled transactions during token launches. Uniswap has rolled out its Continuous Clearing Auctions (CCA) feature on Base, giving developers a new way to launch tokens fully on-chain with built-in price discovery and automatic liquidity setup. The decentralised exchange confirmed the rollout on Jan. 22, with the CCA framework now available to builders using Uniswap v4 on the Base network. The…

Ethereum (ETH) price shows early signs of a potential bullish trend reversal. On-chain data suggests accumulation and weakening selling pressure. A break above $2,300 could trigger further upside momentum. Ethereum has slipped below the $2,200 mark, but the broader picture suggests something more interesting is unfolding beneath the surface. The recent dip reflects short-term weakness, although it does not fully capture the growing signals pointing toward a potential shift in trend. While the price action over the past week shows mild selling pressure, zooming out reveals that Ethereum is still holding onto gains built over the last month. This creates…

The North Star of the Platform team is for Ethereum to scale as a cohesive system and enable confident adoption by all users. This doc is intended to share our perspective on the L1 L2 relationship, the roles of each layer, and how we (as an ecosystem) are leveraging the strengths of L1 & L2 to create the most compelling platform for all users. Some of this is already clear today, and some of this will need to be validated through ongoing experimentation and iteration with the community and users 🙏. On the L1 + L2 relationship TL;DR: Goal: all…

Affected configurations: All smart contract wallets created using Ethereum Wallet  Frontier, version 0.4.0 (Beta 7) or earlier. Wallets created with Ethereum Wallet 0.5.0 and all later versions released after March 3, 2016, are not affected. Likelihood: Low Severity: High Summary: Do not use wallet contracts or owner accounts of those wallets that were created by the Ethereum Wallet 0.4.0 or earlier. If you send to (or interact with) a malicious contract it could take ownership of your wallet contract. Create a new wallet and move your funds. How to be super safe?? Don’t use the vulnerable wallet contracts, AND the owner accounts…

The last week was quite hectic for all of us in the Ethereum ecosystem. The DAO has shown us that it takes much more effort to write smart contracts than we originally anticipated; but also that it takes a surprising amount of debate to reach a consensus on issues of this scale. Everybody in our community was very vocal and forthcoming about how the problem should be fixed in his/her opinion, or whether there’s even a problem to fix in the first place. While many have suggested an immediate hard-fork, the implications of such action are yet to be fully understood. An alternative…

Affected configurations: geth 1.4.8 Likelihood: High Severity: High Details: An attack vector has been identified in the freshly released implementation of the DAO soft fork. The fork enactment code in geth (and other clients) allows execution of EVM code up to the block gas limit without paying for gas. This can slow down mining and prevent inclusion of legitimate transactions. The soft fork will not be enabled if the gas limit of block 1800000 is above 4000000 gas (i.e. if the community vote to activate the fork fails). The attack cannot be performed in this case. Effects on expected chain reorganisation depth: None Proposed temporary…

The Devcon2 web site is officially live now! You can find it at https://ethereumfoundation.org/devcon/ Thanks for everyone’s interest, proposals, support and enthusiasm. We have an amazing community and are excited to present the first Ethereum Foundation event in Asia. This year, Devcon2 (September 19, 20, 21) will be a featured conference at the International Blockchain Week in Shanghai by Wanxiang Blockchain Labs, the host organization in China. While Ethereum Foundation’s “devcon” is designed to be a conference by developers for developers, any and all who are interested in the research and development of the Ethereum platform, tools, and technologies are welcome to attend!…

Since the last C++ DEV Update, a lot of things happened in the engine room which were not really visible to the outside. This post wants to give an overview about what we are currently working on. Apart from the features side, Bob has been working on a proposed process for re-licensing of the C++ runtime client code to Apache 2.0, as has been mentioned a few times in the past month or two. Expect more news on that very soon. Eth Unit-Test Mode Not only because it is essential for being able to perform our Solidity end-to-end tests via…

Hey everyone, I spent some time with our Canadian friends in Toronto after presenting “Ethereum: The World Computer” at Blockchain Training Conference last month and I wanted to provide a quick update on some of the exciting happenings in the Ethereum dev ecosystem. Lots of things are brewing behinds the scenes, so let’s jump in! Projects Mist Ethereum wallet has been refined significantly over the last several months expanding support to arbitrary contract interaction via the “custom contracts” tab. This is a massive improvement over sending transactions on the command line, as was often required in Frontier. With several new…
