🏗 Scaffold-ETH x Buildbear

🧪 Quickly experiment with Solidity using a forked private testnet, from the mainnet, and swapping tokens from Uniswap

Scaffold-Eth x Buildbear lets you create your own private testnet, (optional) forked from the mainnet, with your own native token and ERC20 Token faucet and blockchain explorer

🐻 Features of Buildbear

Creating your private testnet

Using your personal native token faucet

Using your personal ERC20 faucet

Swap your tokens on Forked Uniswap

🏄‍♂️ Quick Start

Prerequisites: Node (v18 LTS) plus Yarn (v1.x) and Git

🚨 If you are using a version < v18 you will need to remove openssl-legacy-provider from the start script in package.json

1️⃣ clone/fork 🏗 scaffold-eth x buildbear:

git clone https://github.com/BuildBearLabs/scaffold-eth.git

2️⃣ install and create your private testnet (forked from the mainnet):

cd scaffold-eth
yarn install
yarn fork-bb

3️⃣ 🛰 deploy your SwapOnUniswap Contract:

cd scaffold-eth
yarn deploy

4️⃣ start your 📱 frontend:

🚨 if you have not created your private testnet please follow the the steps in point 2 above:

cd scaffold-eth
yarn start

5️⃣ you can use your 🚰 faucet directly from the terminal after creating your private tesnet:

# for native tokens
yarn faucet-bb native <Insert Amount (optional)> <Insert Your Wallet Address>

# for erc20 tokens
yarn faucet-bb USDC <Insert Amount (optional)> <Insert Your Wallet Address>

# Please note the supported ERC20 tokens below

# by default faucet mints 100 native / erc20 tokens

Supported ERC20 tokens that can be used :

1. USDC
2. USDT
3. DAI
4. BNB
5. BUSD
6. MATIC
7. WBTC
8. UNI
9. AAVE

# Please note the address for each ERC20 Tokens is automatically updated / changed based on the network that you have forked from
