erc4337Empowering 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.

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...
erc4337ERC-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 ...

The upcoming Pectra upgrade will introduce EIP-7702, which will allow Externally Owned Accounts (EOAs) to function like smart contracts, upgrading them with AA features such as gas sponsorship, transaction batching and custom permissions.
Therefore, we have made sure that EntryPoint v0.8 will offer native support for EIP-7702 authorizations. This will allow any EOA that utilizes EIP-7702 to also make use of the pre-existing and comprehensive ERC-4337 ecosystem of bundlers and paymasters.
In addition, as part of the v0.8 focus on EIP-7702, we added the Simple7702Account contract to the core of the ERC-4337 smart contract distribution. This is a fully audited minimalist smart contract wallet that can be safely authorized by any Externally Owned Account (EOA) and adds full support for all the major features of Smart Contract Accounts.
EntryPoint v0.8 also includes the following changes:
Native support for ERC-712 based UserOperation hash and signatures
The unused gas penalty no longer applies if unused gas is below 40,000 gas
Native Go implementation of ERC-7562 tracer for ERC-4337 bundlers (expected to be merged in Pectra mainnet)
Minor relaxations to ERC-7562 validation rules
Bug fixes for issues discovered as part of the AA Bug Bounty Program:
Prevent initCode front-running
Fix errors in calculating Paymaster postOp actualGasUsed value
Prevent explicitly setting Paymaster as zero address
