# EVMC
[![chat: on gitter][gitter badge]][Gitter]
[![readme style: standard][readme style standard badge]][standard readme]
> 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.
## Usage
### Documentation
Please visit the [documentation].
### Languages support
| Language | Supported Versions | Supported Compilers | Feature Support |
|-------------------------------|----------------------|------------------------------|-------------------|
| **C** | C99, C11 | GCC 8+, clang 9+, MSVC 2017+ | Host- and VM-side |
| **C++** | C++17 | GCC 8+, clang 9+, MSVC 2017+ | Host- and VM-side |
| **Go** _(bindings)_ | 1.11+ (with modules) | | Host-side only |
| **Rust** _(bindings)_[¹](#n1) | 2018 edition | 1.47.0 and newer | VM-side only |
| **Java** _(bindings)_[²](#n2) | 11 | | Host-side only |
1. ↑ Rust support is limited and not complete yet, but it is mostly functional already. Breaking changes are possible at this stage.
2. ↑ Java support is in progress and the interface remains in flux. 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.
