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.

CAVEATS
Not for production. Behavior may differ from mainnet. State is lost on restart (use --database.dbPath for persistence). Forking requires archive node access.
HISTORY
Ganache was developed by Truffle Suite (now part of Consensys). It evolved from TestRPC and was renamed Ganache around 2017. The current version (Ganache 7+) is a complete rewrite supporting forking and improved compatibility.
