Documentation

Build with Chainforge

Short, practical guides — from your first chain to impersonating a whale on forked mainnet state.

Docs are being built. These topics are outlined below and full articles are on the way — in the meantime, the app has everything inline.

Quickstart: create your first chain

Connect, name it, pick a network, and get a funded chain in seconds.

Getting started

Connect & sign in

Wallet connection and SIWE — your address is your identity.

Your funded wallet

Every chain pre-loads your wallet with 100 test ETH.

Add a chain to MetaMask

One click via wallet_addEthereumChain.

RPC endpoint & usage

Your public JSON-RPC URL and how to point tools at it.

Built-in explorer

Browse blocks, transactions, and address pages.

Deploy a contract

Foundry, Hardhat, or raw bytecode against forked state.

viem & ethers setup

Wire a client to the chain in a few lines.

Faucet & funding

Top up any address with test ETH on demand.

Impersonate accounts

Send transactions as any wallet on the fork.

Snapshots & reset

Snapshot state, experiment, and revert instantly.

Time travel & mining

Advance time and mine blocks for time-locked logic.

Pre-funded dev accounts

Ten ready-to-use accounts with known keys.

Networks you can fork

Ethereum, Base, Arbitrum, and Optimism.

Chain lifecycle

Idle cleanup, restarts, and what persists.

Roadmap

Where Chainforge is headed next.

FAQ

Common questions, answered.

Full articles land with v1. Until then, each chain's Settings tab has copy-paste RPC details and the Developer console has the tools inline.
