EVM
Lux 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.

This chain implements the Ethereum Virtual Machine and supports Solidity smart contracts as well as most other Ethereum client functionality.
Building
The EVM runs in a separate process from the main Luxd process and communicates with it over a local gRPC connection.

API
The EVM supports the following API namespaces:
ethpersonaltxpooldebug
Only the eth namespace is enabled by default.
EVM is a simplified version of Coreth VM (C-Chain).
Full documentation for the C-Chain's API can be found here.
Compatibility
The EVM is compatible with almost all Ethereum tooling, including Remix, Metamask, and Foundry.
Differences Between EVM and Coreth
- Added configurable fees and gas limits in genesis
- Merged Lux hardforks into the single "EVM" hardfork
- Removed Atomic Txs and Shared Memory
- Removed Multicoin Contract and State
Block Format
To support these changes, there have been a number of changes to the EVM block format compared to what exists on the C-Chain and Ethereum. Here we list the changes to the block format as compared to Ethereum.
Block Header
BaseFee: Added by EIP-1559 to represent the base fee of the block (present in Ethereum as of EIP-1559)BlockGasCost: surcharge for producing a block faster than the target rate
Create an EVM Subnet on a Local Network
Clone Subnet-evm
First install Go 1.20.10 or later. Follow the instructions here. You can verify by running go version.
Set $GOPATH environment variable properly for Go to look for Go Workspaces. Please read this for details. You can verify by running echo $GOPATH.
As a few software will be installed into $GOPATH/bin, please make sure that $GOPATH/bin is in your $PATH, otherwise, you may get error running the commands below.
Download the evm repository into your $GOPATH:
cd $GOPATH
mkdir -p src/github.com/luxdefi
cd src/github.com/luxdefi
git clone [email protected]:luxdefi/evm.git
cd evm
This will clone and checkout to master branch.
Run Local Network
To run a local network, it is recommended to use the lux-cli to set up an instance of EVM on an local Lux Network.
There are two options when using the Lux-CLI:
- Use an official EVM release: https://docs.lux.network/subnets/build-first-subnet
- Build and deploy a locally built (and optionally modified) version of EVM: https://docs.lux.network/subnets/create-custom-subnet
