Subnet EVM

Avalanche is a network composed of multiple blockchains. Each blockchain is an instance of a Virtual Machine (VM), much like an object in an object-oriented language is an instance of a class. That is, the VM defines the behavior of the blockchain.

Subnet EVM is the Virtual Machine (VM) that defines the Subnet Contract Chains. Subnet EVM is a simplified version of Coreth VM (C-Chain).

This chain implements the Ethereum Virtual Machine and supports Solidity smart contracts as well as most other Ethereum client functionality.

Building

The Subnet EVM runs in a separate process from the main AvalancheGo process and communicates with it over a local gRPC connection.

API

The Subnet EVM supports the following API namespaces:

eth
personal
txpool
debug

Only the eth namespace is enabled by default. Full documentation for the C-Chain's API can be found here.

Compatibility

The Subnet EVM is compatible with almost all Ethereum tooling, including Remix, Metamask and Truffle.

Differences Between Subnet EVM and Coreth

Added configurable fees and gas limits in genesis
Merged Avalanche hardforks into the single "Subnet EVM" hardfork
Removed Atomic Txs and Shared Memory
Removed Multicoin Contract and State
Removed DAO Hardfork Support
