🚀 MEE Contracts and versions

The Modular Execution Environment (MEE) is Biconomy’s Smart Account and Execution infrastructure (which is compliant with and built on ERC 4337) that enables gasless transactions and modular execution flows. Below is a comprehensive list of supported chains and their corresponding MEE versions. On the Biconomy Dashboard, set up a project on the Supertransaction tab, get an API key and you will have full access to all chains with just one API key. For detailed information about contract addresses and audit reports for each version, please check our contracts and audits page.

🔧 ERC-4337 Infra Support

​
EntryPoint v0.7.0 – Nexus Smart Account (v1.0.2)

Please note, we are not suppporting new chains with this infrastructure. Any new chains we support will utilise our newer and advanced MEE stack, and thus the newer chain support are added to the above MEE Contracts and Services list. If you are a new developer, or starting a new project to find the chains we support, do not reference this list.
Why did we move to MEE in favour of ERC 4337? You can learn more here.
