The vulnerability only applies to a small fraction of the UserOperations visible before execution (i.e. transactions sent to the ERC-4337 UserOperation mempool). It’s a griefing/censorship vector, not fund theft, and is fixed in v0.9.
Trust@TrustSecAudits

Today, in coordination with @ethereumfndn, we're disclosing a high-severity DoS attack affecting the core of ERC4337 account abstraction. Users are strongly encouraged to migrate to v0.9 wallets where the issue is mitigated. This previously unseen attack vector weaponizes various safety checks including reentrancy guards which are ubiquitous in modern DeFi infrastructure, to deny withdrawals and disrupt core functionality for AA users. From our research, a meaningful share of AA DeFi activity could be disrupted. Huge thanks to the EF for handling the issue responsibly and granting us a $50k bounty, the maximum high-severity award. We've also reached out to major affected dApps in order to guard their AA users. We'd like to commend projects that took quick action and upheld their commitment both to their users and the whitehat community - an additional $59.5k was granted by affected dApps. Full disclosure of relevant DeFi products and their responses will be released soon. Additional details including root cause analysis can be found in the EF disclosure below. TrustSec is determined to continue safeguarding the Ethereum ecosystem, even from the most surprising attack vectors.

ERC-4337 made accounts programmable. EIL extends that programmability across chains. EIL is fundamentally an execution pattern for accounts. It extends account abstraction to multichain execution, allowing a single account to authorize and execute cross-chain transactions with one signature, while preserving Ethereum’s trust and security model. EIL answers this narrow question: How can an account initiate and settle execution across chains without introducing trusted intermediaries? If we don’t answer this question, we guarantee the answer lives somewhere else - outside the protocol. The account abstraction roadmap is not complete until a single account can safely execute across the chains users already live on. More here ⬇️

What is the EIL? The EIL focuses on trustlessness. Wallet-centric, cross-chain orchestration where the user is always in control - without the intermediaries. But what does this mean for markets today, and how could markets look with wider adoption of the EIL? Read more: li.fi/knowledge-hub/…

EntryPoint v0.9 (released Nov 2025) included a fix based on a responsibly disclosed AA bug bounty report by security experts at TrustSec Thanks to @trust__90 for the thorough analysis and close coordination throughout the disclosure process 🤝 open.substack.com/pub/erc4337/p/…

This is what ERC-4337 was designed for 🚀 Bundlers are replaceable infrastructure and not wallet dependencies. Allowing per-network bundler selection enables real competition, experimentation, and censorship resistance in the AA mempool. Great step forward by @ambire!

Calling all bundlers. From @ambire v5.34.6, we're allowing a custom bundler URL for each network. We're trying to give space to ERC-4337 developers to experiment more. If you are a bundler, place your bundler URL and broadcast a few userOps with Ambire!

EIL makes AA multichain 🚀 AA abstracts validation and gas. EIL uses that to let users self-execute across chains without holding native gas or trusting relayers. This is exactly the kind of trust-minimized UX AA was set to unlock from the beginning.

At DevConnect Buenos Aires, the details of EIL @ethinteroplayer - Ethereum Interoperability Layer were unveiled. We’ve been deep-diving interop protocols for months and our initial assessment of EIL contracts (deployed on testnets already) is following 🧵👇

Hackers, it’s live 👇 
The Stitch SDK - a lightweight wrapper for the EIL tech stack - is now public for anyone building DeFi, built on top of @ethinteroplayer, @erc4337 and backed by @ethereumfndn. I’m making the repo public right before my talk at @ETHGlobal today at 5pm, where I’ll walk through how it works and how you can use it during the hackathon. Thnks to AA team @ThewizardofPOS, @tomteman and @yoavw for pushing this forward - and shoutout to @syndika_co and the whole builder crowd this week. Jump in, fork it, break it, ship something cool.

Our team had a great time at @EFDevcon connecting with everyone at the AA Community Hub. We demoed permissioned x402 payments for agents built on top of @erc4337 infra, and loved the thoughtful conversations that followed. Thanks to everyone who stopped by 🫶
