ganache
personal Ethereum blockchain for development
TLDR
SYNOPSIS
ganache [options]
DESCRIPTION
Ganache is a personal Ethereum blockchain for development. It simulates full client behavior, providing instant transaction mining, configurable accounts, and blockchain forking.Developers use Ganache to test smart contracts locally before deploying to testnets or mainnet. It integrates with Truffle, Hardhat, and other development frameworks.
PARAMETERS
-p, --port port
Port to listen on (default 8545).-h, --host host
Hostname (default 127.0.0.1).-a, --accounts num
Number of accounts to generate (default: 10).-e, --defaultBalanceEther amount

Allow unlimited contract sizes for debugging.
CAVEATS
Not for production. Behavior may differ from mainnet. State is lost on restart (use --db for persistence). Forking requires archive node access. Ganache was deprecated in December 2023 when Consensys sunset both Truffle and Ganache. Developers are encouraged to migrate to Hardhat or Foundry.
HISTORY
Ganache was developed by Truffle Suite (part of Consensys). It evolved from TestRPC and was renamed Ganache around 2017. The current version (Ganache 7+) was a complete rewrite supporting forking and improved compatibility. In September 2023, Consensys announced the sunset of both Truffle and Ganache, with codebases archived in December 2023.
