#Avalanche is a platform that powers decentralized applications to execute transactions. It consists of networks called subnets, which include custom virtual machines (VMs) and complex sets of validator rules.

One of these virtual machines is Subnet-EVM, which allows you to customize the deployment of virtual machines with the help of stateful precompilation, allowing the subnet to adapt to all your dApp needs.

Subnet-EVM is a simplified version of Coreth, which is the virtual machine (VM) of the contract chain (C-Chain). It implements the Ethereum Virtual Machine (EVM) and supports Solidity smart contracts, as well as most other Ethereum client features, and is compatible with many EVM toolchains and wallets.
