ChainCatcher news, the secure blockchain application standard OpenZeppelin has been funded by the Ethereum Foundation. The official statement indicates that this grant will enable them to add a modular ERC-4337 implementation, advancing account abstraction and helping developers build safer applications and more flexible smart wallets. In addition, the team will introduce new signature schemes, such as secp256r1, BLS, and RSA, thereby providing broader cryptographic support.

ChainCatcher news, Toyota Blockchain Lab published a blog post stating that it is researching how to introduce mobility into public blockchains. Exploring the construction of "MOA" (Mobility-Oriented Account) based on the account abstraction standard ERC-4337 in the Ethereum ecosystem.MOA account abstraction separates the authentication process from key management, ensuring that even if the private key is lost, the account itself can be retained. This makes account management more secure and flexible. By preserving a state available for external reference, information related to vehicles (such as usage history and maintenance records) can be managed more transparently and efficiently.In addition, MOA allows operations to be executed with the approval of multiple entities (rather than a single entity). This enables various stakeholders, including vehicle users, owners, manufacturers, dealers, and regulatory agencies, to participate in the approval process for vehicle-related transactions.It is reported that the Toyota Blockchain Lab is an organization established within the Toyota Group in 2019, aimed at promoting the use of blockchain. Initially focused on corporate projects related to material and information traceability, its activities have recently expanded to include public chain-related topics such as web3 and innovative finance.

ChainCatcher news, according to The Block, account abstraction infrastructure Pimlico integrates wallet provider Safe's ERC-4337 module to enhance its account abstraction infrastructure, allowing its clients to create Ethereum-based products, improving user experience and security. Pimlico will be the first company to integrate Safe accounts using the ERC-4337 module and will act as a Bundle within the Safe ecosystem.

ChainCatcher message, Etherscan stated on social media that it currently supports the simple display of ERC-4337 account abstraction transactions.It is reported that account abstraction allows the use of smart contract wallets to pay Gas fees without the need for private keys or maintaining an ETH balance. ERC-4337 is a standard that implements account abstraction through the EntryPoint contract.

ChainCatcher news, cryptocurrency custody platform Fireblocks stated that it recently discovered an ERC-4337 account abstraction vulnerability in the smart contract wallet UniPass. This vulnerability allows attackers to fully take over the UniPass wallet by replacing the wallet's trusted EntryPoint to activate the account abstraction module. Once the account takeover is complete, the attacker can treat the wallet as their own and steal all the funds within it. The vulnerability has now been fixed in collaboration between both parties.

ChainCatcher message, Vitalik Buterin stated in the latest blog post on Bankless:The cryptocurrency space needs more imaginative innovations, not just improvements to existing systems, but the creation of an entirely new ecosystem where components can complement each other. For example, decentralized social is moving in this direction.Cryptocurrencies can serve as a laboratory to test new mechanisms and ideas. For instance, new tools for public interest funding and capital allocation. These innovations can permeate into the broader world.Cryptocurrencies can fill the gaps left by governments and markets in providing certain public goods, such as anti-aging research. Large-scale experiments can be conducted through community participation.A balance needs to be found between decentralization and security. The goal is to build an ecosystem where people can earn returns without taking on huge risks. This requires a shift away from the mindset of solely pursuing maximum returns.New technologies like ZK and ERC-4337 create opportunities for newcomers to participate. There are also new tracks worth paying attention to, such as enterprise solutions.As we enter the next bull market, here are a few points to keep in mind: do not overly pursue returns at the expense of security; find a balance between decentralization and security; change the mindset of solely pursuing maximum returns.

ChainCatcher News, the Ethereum Foundation announces the successful completion of the ERC-4337 account abstraction funding round. This funding program will support 18 teams building diverse projects around ERC-4337 (also known as account abstraction):ZeroDev Kernel: A smart contract account designed from scratch for account abstraction wallets, efficient and modular.Etherspot's Skandha Bundler: A P2P interface account abstraction Bundler implementation developed by the Etherspot team.MynaWallet: A contract account integrated with identity cards issued by the Japanese government.Blocto: RPC methods supporting account abstraction in web3.js.Silius: A modular and efficient Rust account abstraction Bundler implementation.QR-Seal: A fully ERC-4337 compatible Schnorr multi-signature wallet.Ambire: A self-custody wallet using email/password authentication.IoTeX: An account abstraction wallet based on zero-knowledge proofs.SixdegreeLab: A data analytics dashboard for account abstraction.Jam: A DeFi transaction batch processor developed by Picnic.TokenSight: Account abstraction multi-factor authentication using WebAuthn.ZK-Team: Privacy-protecting account abstraction provided by PriFi Labs for teams.Rhinestone: A secure registry for modular account abstraction.AAA: Community activities to enhance awareness of account abstraction.Unpacking 4337: A series of technical articles on account abstraction.Hexlink: Linking ENS with ERC-4337 accounts using EIP-4972, providing instantly usable account abstraction compatible smart accounts for all ENS users.UniPass: Combining ERC-4337 to provide one-click OAuth login and account creation for new users via the OpenID Connect protocol.Clave: Enhancing support for account abstraction with the secp256r1 curve.

ChainCatcher news, CyberConnect's official Twitter stated that CyberAccount has now integrated with the Base network, bringing ERC-4337 supported smart accounts to Base.

ChainCatcher news, according to Tally, the AIP-2 proposal to activate support for account abstraction endpoint on Arbitrum One and Nova has been passed, with a voting support rate of 99.95%, and is currently awaiting execution.The proposal states that Ethereum researchers have introduced a new RPC endpoint eth_sendRawTransactionConditional, which allows L2 sequencers to adapt to the specific needs of ERC-4337 bundlers. Offchain Labs supports the Arbitrum sequencer endpoint to Nitro v.2.0.14 by developing, testing, and integrating the necessary adjustments, which is now enabled on the Arbitrum testnet. This AIP suggests that the Arbitrum DAO activate support for this endpoint on the Arbitrum One and Nova mainnets.It is reported that due to EIP-4339 separating the validation and execution steps in the bundling of transactions for submission to alternative mempools, this split poses potential issues for bundlers processing L2 transactions. The delay between the initial submission of a transaction and its final inclusion may result in changes to the storage of smart contract accounts, rendering the transaction invalid. The new RPC endpoint allows users to specify a valid range for block height and timestamp, enabling sequencers to reject transactions that do not meet inclusion conditions during the early validation phase, thereby mitigating the risk of changes in account storage occurring between validation and execution.

ChainCatcher news, the self-custody wallet Soul Wallet has announced the completion of a $3 million seed round financing, co-founded by Jiajun Zeng, who was previously a product manager at ByteDance and Meituan.It is reported that Soul Wallet will provide a self-custody Ethereum wallet based on ERC-4337, currently undergoing internal testing, and plans to launch in Q3 or Q4.

ChainCatcher news, Ethereum Foundation security researcher Yoav Weiss announced at WalletCon in Denver that the ERC-4337 account abstraction contract has passed Open Zeppelin's audit and will be available on every Ethereum EVM-compatible network, including Polygon, Optimism, Arbitrum, BNB Smart Chain, Avalanche, and Gnosis Chain. ERC-4337 allows new users to enter the decentralized crypto world without needing to learn complex mnemonics or go through the technical process of setting up a wallet. (Cointelegraph)
