Decentralized & Censorship Resistant AA​

One year ago marked a significant milestone with the launch of the first production-ready ERC-4337 entrypoint contract, with the premise of decentralized Account Abstraction using an alternative mempool. The limitations and vulnerabilities of centralized server approaches for smart accounts highlighted the importance of building decentralized and censorship-resistant solutions. ERC-4337 offers a permissionless bundler network to deliver UserOperations without even changing or censoring them. Bundlers are incentivized to participate in the service. They are also protected against grieving attacks thanks to the Entrypoint design. The network is protected from Denial-of-service (DoS) attacks ensuring continuous operation and resilience. The shared mempool was developed collaboratively with engineering teams from Candide, ERC-4337, Etherspot, Silus and Alchemy.

Candide released AbstractionKit v0.1.x, adding first-class support for the new fully audited ERC-4337 Safe canonical module. Audits by Open Zepplin and Ackee. At its core, AbstractionKit empowers developers to build Smart Wallets using Safe Contracts and the ERC-4337 standard, ushering in a new era of possibilities:

Voltaire is a modular and lightning-fast Python Bundler for Ethereum EIP-4337 Account Abstraction. It is designed to operate within the peer-to-peer mempool of user operations, facilitating the inclusion of transactions on-chain more quickly, at the frontier of efficiency. A good way to think about Voltaire is as software that delivers User Operations and cannot change them, similar to those expected of block-builders. It is incentivized to participate in the network through priority fees and MEV.

Voltaire presently has complete coverage of the compatibility test suites written by ERC-4337 team. These test suites ensure that different bundlers can communicate effectively and defend against DDoS attack vectors. While the specification is still under development, all upcoming updates will aim to sustain full compliance coverage.

Voltaire is open-source, meaning that anyone can launch Voltaire and capture User Operation profits. By participating in the network, the mempool becomes more robust when facing censorship attacks.
