Introduction

contract.dev is a platform for smart contract experimentation. At its core is The Stagenet, an ultra-realistic private EVM testnet that replays mainnet blocks and is enhanced with a suite of built-in development tooling.

Stagenets connect to GitHub repositories and automatically import their smart contracts, giving each one its own dedicated Contract Workspace. Inside each Workspace, you’ll find rich contract analytics — e.g. activity, state, and token/ETH balances — along with version and deployment tracking.

Stagenets also come with a built-in explorer tailored to your project's contracts, an unlimited ETH and ERC-20 faucet, and a growing range of other development tools. All this, embedded within a true-to-life private blockchain, provides a powerful sandbox for testing your smart contracts.
