Compatibility Test Suite
Overview and link to external bundler conformance test results.
This Bundler Compatibility Test Suite results page serves as a reference for ongoing compatibility testing across bundlers in the ERC-4337 ecosystem.
An external test suite has been developed to verify that bundlers:
Correctly implement the EntryPoint interface
Respect simulation and validation rules
Safely handle edge cases and reverts
🔍 What’s Being Tested?
EntryPoint version support (v0.6, v0.7, v0.8)
Proper
simulateValidation()implementationBundle construction and submission behavior
Error reporting and handling
The tests simulate a wide variety of UserOperations, from valid edge cases to intentionally malformed payloads.
🧪 Test Results
Test results are tracked live at:
👉 https://bundlers.erc4337.io/
This includes:
A matrix of passing/failing tests for each bundler
Notes on client-specific quirks or deviations
Historical conformance data
🛠️ How to Contribute
Published your own open source bundler? To add your bundler to the list, please submit a PR.
Feedback and patches are encouraged to expand the coverage and ensure consistent behavior across the ecosystem.
✅ Summary
This test suite helps ecosystem participants confidently choose, integrate, or build bundlers. Check the linked dashboard for up-to-date compliance information.
