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
