  Pure Rust implementation of Ethereum Virtual Machine

  

The Neon EVM core program is based on the Sputnik VM, an implementation of the Ethereum Virtual Machine written in Rust. Sputnik VM includes a feature to embed third-party Rust code that can be invoked from Ethereum contracts. This embedded code is known as a “precompiled contract”.

  OpenZeppelin Contracts is a library for secure smart contract development.

  

The ERC-20 Wrapper’s Solidity contract code includes the IERC-20 Interface with its standard functions and events, and the Neon code extends this Interface with its own functions, implementing only the constructor and the fallback function.
