Etherspot Brings Account Abstraction Infrastructure to Celo
Etherspot has announced that its comprehensive account abstraction infrastructure is now compatible with Celo, offering developers a more accessible and intuitive way to build decentralized applications.
Celo, a mobile-first blockchain L2 network, is characterized by low fees, energy efficiency, and a strong focus on environmental sustainability. By offsetting more carbon than it produces, Celo appeals to projects prioritizing both global reach and eco-conscious operations. Its EVM compatibility also allows developers to build on familiar foundations while benefiting from lower costs and scalability enhancements.
With Etherspot’s solution now live on Celo, developers can integrate advanced features such as session keys and social recovery through a modular SDK that supports the latest account abstraction standards like ERC-7579. The Skandha Bundler secures transactions against potential MEV threats, while the Arka Paymaster enables flexible gas options — including fully sponsored transactions. Users can pay fees in any supported ERC-20 token or even bypass gas costs entirely.
The collaboration aims to elevate the user experience for dApps in areas ranging from DeFi to real-world payment solutions. By combining Etherspot’s infrastructure with Celo’s mobile-first design and carbon offset initiatives, developers can build applications that are both powerful and sustainable, serving a broader audience seeking accessible, secure, and efficient blockchain services.
Vitalik Urges Higher Ethereum L1 Gas Limits Despite L2-Centric Roadmap
Vitalik Buterin has released a new blog post arguing that increasing Layer-1 gas limits offers significant benefits even in a rollup-centric Ethereum ecosystem.
He notes that although Ethereum is moving toward greater reliance on L2 solutions — such as Optimistic and ZK rollups — boosting L1 capacity can enhance censorship resistance, improve cross-L2 asset transfers, and support key features like mass exits, ERC20 issuance, and trust-minimized wallets.
Buterin explains that relying on L2s alone could expose users to censorship risks from centralized sequencers. He stresses the importance of being able to bypass any hostile L2 by submitting transactions directly on L1, which requires low enough fees and sufficient capacity.
He also explores scenarios like transferring NFTs between different L2s, arguing that higher L1 throughput would reduce friction and ensure smooth cross-chain movement. In the event of a worst-case “mass exit,” he shows that upgraded L1 capacity could allow large user bases, potentially in the tens of millions, to exit a broken L2 within tight timeframes.
Vitalik concludes that a roughly tenfold increase in L1 scalability could address diverse user needs, including cheaper L2 proof submissions and more efficient keystore wallet operations. Overall, Buterin encourages near-term L1 upgrades, emphasizing that they provide valuable protection and ease of use, regardless of how heavily Ethereum eventually depends on L2 solutions.
On-Chain Identifiers and Proof Systems for Chain Abstraction
Researcher Eugenio Reggianini has published a comprehensive post on EthResearch, proposing a framework that combines on-chain identifiers with proof systems to overcome fragmentation and enhance user experiences across Ethereum’s modular networks.
The post argues that current multichain approaches still struggle with interoperability, security, and data consistency. It suggests that integrating decentralized identifiers, such as user IDs and contract IDs, alongside zero-knowledge, Merkle, and fraud proofs can unify verification processes. By linking these identifiers to keystore contracts, the framework aims to enable secure key management, dynamic transaction execution, and cross-chain operations — all while preserving privacy and reliability.
The post emphasizes that many existing solutions lack seamless coordination across different execution and consensus layers, leading to usability challenges and elevated security risks. Proposed features include session key rotation, aggregated signatures, and trustless validation workflows.
According to the author, integrating these elements would significantly simplify developer efforts and reduce reliance on centralized bridging mechanisms. Users could then issue cross-chain transactions without worrying about the underlying network structure, thanks to orchestrated agent systems that handle complex routing tasks.
This approach aspires to unify Ethereum’s roll-up-centric roadmap and broader multichain strategies, offering a potential path to standardize off-chain verifiable data on-chain.
DappRadar Adds ERC-4337 Account Abstraction Tracking
DappRadar has announced new support for ERC-4337 account abstraction, ensuring accurate tracking of wallet activity and transaction volume across multiple blockchains.
By adding an ERC-4337 configuration to its open-source repository, developers can submit their EntryPoint and Smart Contract Wallet details, enabling transactions to be parsed and decoded. This integration covers essential implementation steps, such as verifying ABIs, handling addresses in checksum format, and matching function names precisely with deployed contracts.
Projects that complete the configuration will see improved metrics for Unique Active Wallets (UAW) and transaction counts. For issues, a dedicated GitHub repository provides troubleshooting guides and support.
KRNL & Sig Network Launch Secure Cross-Chain Bridge for Instant Transactions
KRNL Labs and Sig Network have introduced a new cryptographically secured cross-chain bridge designed to eliminate delays, reduce fees, and expand interoperability across multiple blockchains.
Developed by KRNL’s team alongside Sig Network’s Multi-Party Computation (MPC) technology, this bridge allows users to move digital assets between chains instantly, creating a single deposit on the origin chain and a single withdrawal on the destination chain.
“The result of this exciting development between Sig Network and KRNL enhances cross-chain interactions by providing a cryptographically secure bridge that eliminates confirmation times and reduces fees, enabling truly seamless blockchain interoperability,” said Tahir Mahmood, co-founder of KRNL Labs.
The new solution secures transactions through distributed key management rather than relying on third-party consensus or messaging networks. No additional smart contracts are required on the destination chain, with Sig accounts acting as “liquidity pools” and only a Near Protocol contract involved. The system includes an NFT Chain Keys mechanism, which generates multiple keys capable of managing various addresses. This approach streamlines dApp interactions, allowing asset owners to issue, revoke, and manage cross-chain usage approvals more efficiently.
With this bridge, KRNL Labs and Sig Network aim to minimize risks, cut costs, and reduce development time by unifying and simplifying interoperability for any compatible chain.
