Empowering Innovation: ERC-4337 Account Abstraction Grant Round Recipients
The Ethereum Foundation is pleased to announce the successful conclusion of the ERC-4337 Account Abstraction grant round. This grant initiative will support 18 teams in their efforts to build diverse projects centered around ERC-4337, also known as Account Abstraction. Each team's project uniquely aligns with the goals of the ERC-4337 AA grant, and we believe that the outcomes of these endeavors will ripple through the ecosystem, inspiring new ideas and opportunities for collaboration.

EntryPoint 0.6.0 Released
Following feedback from the community, we have pushed and deployed a new version of the EntryPoint contract, with a few modifications. The latest address is 0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789 The changes are:Align on-chain and off-chain UserOperation hash - PR#245Nonce managed by EntryPoint - PR#247Prevent recursion of handleOps - PR#257Together, they guarantee that now there is a consistent view of the UserOperation :The UserOperation hash is always uniqueEvents emitted by the execut...

ERC-4337 Mempool Stages: A Framework to Assess Bundlers Maturity
ERC-4337 aims to bring Account Abstraction to Ethereum while maintaining strong decentralization and censorship-resistance, aligning closely with the block production security of the underlying chain. Launching a truly public and decentralized mempool for ERC-4337 is a complex process, and development will progress with “training wheels” — a controlled setup that allows for system updates and bug fixes in a safer environment. While necessary in the early stages, these training wheels will be ...

Push Protocol, a communication protocol built for web3, recently completed phase 1 of its Billion Reasons to Build (BRB) developer tour in India.
One of the hackathon participant successfully solved a challenge brought forth by our team: quantum proofing Ethereum accounts.
Ethereum uses Elliptic Curve Digital Signature Algorithm (ECDSA) for signing its transactions. Transactions hashes are public on the blockchain, which means anyone can retrieve the public key corresponding to the private key used to sign that transaction. In a post-quantum world this becomes a serious issue, as it is proven that ECDSA is vulnerable to a modified Shor’s algorithm for solving the discrete logarithm problem on elliptic curves and thus can be broken by a sufficiently strong quantum computer. That would mean the public key would be as sensitive as the private key, since revealing your public key would lead to leaking your private key as well.
Since ERC-4337 lets accounts abstract their signature validation schemes, a possible solution (using also ZK STARKs) has been presented by Aditya Bisht, one of the hackathon participants, and the winner of our bounty. We recommend reading Aditya’s excellent post explaining their submission, as well as the problem breakdown and proposed solution by researcher Aayush Gupta.
As the world of technology rapidly evolves and the dawn of quantum computing approaches, the need for innovative solutions to protect our digital assets becomes paramount. This recent hackathon submission is a testament to the proactive steps being taken within the blockchain community to safeguard against these emerging threats.
