EVMC
Ethereum Client-VM Connector API
The EVMC is the low-level ABI between Ethereum Virtual Machines (EVMs) and Ethereum Clients. On the EVM side it supports classic EVM1 and ewasm. On the Client-side it defines the interface for EVM implementations to access Ethereum environment and state.

1. Rust support is limited and not complete yet, but it is mostly functional already. Breaking changes are possible at this stage.
Testing tools
- evmc run (tools/evmc) — executes bytecode in any EVMC-compatible VM implementation.
- evmc-vmtester (tools/vmtester) — can test any EVM implementation for compatibility with EVMC.
- evm-test (evmone → test/unittests) — allows running the collection of evmone's unit tests on any EVMC-compatible EVM implementation.
- evmone-fuzzer (evmone → test/fuzzer) — differential fuzzer for EVMC-compatible EVM implementations.
