This compatibility matrix is based on: * [cosmos/evm v0.5.1](https://github.com/cosmos/evm/tree/v0.5.1) * [JSON-RPC simulator](https://github.com/cosmos/evm/tree/v0.5.1/tests/jsonrpc/simulator) * [Geth v1.16.3 comparison context](https://github.com/cosmos/evm/blob/v0.5.1/tests/jsonrpc/scripts/geth/start-geth.sh) * [Ethereum Execution APIs](https://github.com/ethereum/execution-apis) ## Legend * **✅**: Functional * **🟡**: Compatibility response (null/empty/zero) * **❌**: Not implemented or unavailable * **🌐**: Publicly exposed * **🔒**: Not publicly exposed ## Full Method Matrix | Namespace

Revalidate behavior against your deployment before production rollout.
