Ethereum Foundation Launches Open Intents Framework
The Ethereum Foundation has announced the Open Intents Framework (OIF), a modular, open standard designed to enhance interoperability across the Ethereum ecosystem.
Developed in collaboration with more than 30 teams, from Layer-2 networks to wallet providers and infrastructure projects, OIF aims to simplify cross-chain communication and improve developer flexibility.
Although OIF initially ships with a basic Hyperlane settlement mechanism, the framework encourages multiple settlement approaches. Solutions like RRC-7755, Hashi’s Oracle Aggregator, Espresso’s confirmation layer, Optimism’s native interoperability, and Arbitrum’s Cross-chain Broadcaster Standard can all integrate seamlessly into the Base7683 contract.
This diversity lets developers pick the trust model and speed most suited to their application, while upcoming cross-chain messaging standards (e.g., ERC-7786, ERC-7841, ERC-7854) add further modular verification options.
Projects already leveraging OIF attest to its adaptability. Eco, for instance, is modifying the framework’s reference solver for its Eco Routes system, which delivers permissionless cross-chain stablecoin liquidity.
Liquidity management is another emerging focus, with Everclear bringing automated rebalancing to the reference solver and Arbitrum’s Nomial module slated to power intent settlement.
Meanwhile, Uniswap’s Compact initiative explores resource locks that could further optimize how user intents are routed, while platforms like Khalani facilitate solver collaboration and expand reach.
Wallets and user interfaces, such as Superbridge, reduce integration hurdles by making it easier to add framework modules or build new intent protocols. In doing so, they help developers benefit from secure, flexible cross-chain interactions without getting tangled in complex interoperability challenges.
Etherspot Introduces RPC Playground for Efficient AA Development
Etherspot has introduced the RPC Playground on its Developer Dashboard, a comprehensive testing and debugging tool designed to simplify the creation of Account Abstraction dApps. This feature lets users send JSON-RPC requests to Ethereum-based nodes — think of Postman for Web3, tailored for AA.
With this new feature, developers can easily validate gas sponsorship, paymaster interactions, and entry points, minimizing the guesswork involved in complex AA flows.
The playground allows users to pick a preferred network (testnet or mainnet), select an API version, and authenticate via an API key. Once connected, real-time JSON requests and responses provide immediate visibility into gas fees, user operations, and transaction data, helping teams rapidly identify issues and optimize performance.
Another highlight is one-click cURL command generation, which helps integrate validated requests directly into projects with minimal overhead. Developers can use the playground to debug or finalize features such as eth_sendUserOperation calls, ensuring everything works as intended before the production release.
By consolidating multi-chain testing in a single location, Etherspot aims to reduce friction, boost developer productivity, and ultimately accelerate the adoption of Web3 technologies.
For a detailed guide on setup and best practices, read the documentation.

Okto’s Chain Abstraction Testnet to Streamline Multi-Chain Development
Okto has introduced its new Testnet for the Okto Platform, an end-to-end chain abstraction solution that simplifies dApp development and cross-chain transactions. The solution promises to reduce development time by up to 90% and already supports major blockchain ecosystems, including EVM-compatible networks, HyperLiquid, Aptos, Solana, and Cosmos chains.
The platform has undergone more than two years of development, with rigorous testing of cross-chain functionality, liquidity optimization, and interoperability. Designed to abstract away the complexities of building on multiple networks, Okto enables developers to integrate Web3 features into applications with minimal overhead. The Okto Wallet, which has facilitated over 12 million wallet creations, highlights the platform’s capacity for large-scale adoption and demonstrates its commercial viability.
Rohit Jain, Head of DeFi Initiatives at Okto, noted that collaborations with industry leaders, such as Nethermind, Silence Labs, and Agoric, serve as the backbone for the platform’s robust multi-chain capabilities. Okto helps developers focus on core product innovation by removing many barriers to interoperability while ensuring users enjoy a frictionless cross-chain experience.
EIP-7702 Brings Gasless Transactions to Externally Owned Accounts
In a recent blog post, the author outlines how EIP-7702 will allow Externally Owned Accounts (EOAs) to acquire and revoke smart contract code. Slated for introduction on the Holesky testnet on February 24, this proposal transforms a standard EOA into a fully capable smart account, enabling features like gasless transactions.
By linking EIP-7702 to ERC-4337’s paymaster infrastructure, fees can be sponsored on behalf of the user, a function previously exclusive to contract-based wallets.
Under the new system, an EOA signs an authorization that includes a nonce and a target contract address. When the transaction is broadcast, the EOA’s code becomes a “pointer” to that contract, gaining the ability to execute arbitrary logic. The code persists until explicitly updated or revoked, which simplifies ongoing smart account functionality.
According to the blog post, pairing EIP-7702 with ERC-4337 is especially powerful since ERC-4337 already manages key operations — such as validating signatures and routing sponsored transactions — through a battle-tested standard.
In practice, this means an existing EOA can upgrade to a contract-like account and benefit from advanced features without needing a new address.
AA x Falcon: Progress Toward a Post-Quantum Ethereum
A recent EthResearch post outlines how Falcon, a post-quantum signature scheme, can be incorporated into Ethereum through Account Abstraction. Building on two previous articles that examined quantum-resistant cryptography and Falcon’s suitability, this third installment focuses on leveraging ERC-4337-based smart wallets to support Falcon without altering Ethereum’s core consensus rules.
By transitioning traditional ECDSA signatures to Falcon, developers can create quantum-resistant “FalconSimpleWallets,” which rely on explicit public key verification rather than ecrecover.
While these smart wallets significantly reduce vulnerabilities once quantum computing becomes a threat, the broader pipeline remains partially exposed: bundler transactions in ERC-4337 continue to use ECDSA. The post suggests that fully removing ECDSA from the process may require protocol-level modifications, such as EIP-7701 or RIP-7560.
The author also points out potential optimizations. Ongoing research into Falcon signature aggregation, similar to methods used for BLS, could cut costs further if integrated with proposals like EIP-7766 for ERC-4337.
While Falcon-based verification currently runs at around 3.7 million gas per transaction, the community is exploring more efficient implementations. Moving forward, the post-quantum roadmap aims to reduce these costs and address bundler-level ECDSA, ultimately paving the way for a quantum-secure Ethereum.
