🚨🚨 This repository has been archived and is now read-only 🚨🚨

You are still welcome to fork and use as a template but no more changes will be made to this repository.

🎖 Scaffold-ETH 2 is the latest version, we recommend you fork: https://github.com/scaffold-eth/scaffold-eth-2

---

everything you need to build on Ethereum! 🚀

🧪 Quickly experiment with Solidity using a frontend that adapts to your smart contract:

🏄‍♂️ 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:

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

2️⃣ install and start your 👷‍ Hardhat chain:

cd scaffold-eth
yarn install
yarn chain

3️⃣ in a second terminal window, start your 📱 frontend:

🚨 if your contracts are not deployed to localhost, you will need to update the default network in App.jsx to match your default network in hardhat-config.js.

cd scaffold-eth
yarn start

4️⃣ in a third terminal window, 🛰 deploy your contract:

🚨 if you are not deploying to localhost, you will need to run yarn generate first and then fund the deployer account. To view account balances, run yarn account. You will also need to update hardhat-config.js with the correct default network.

cd scaffold-eth
yarn deploy

🔏 Edit your smart contract YourContract.sol in packages/hardhat/contracts

📝 Edit your frontend App.jsx in packages/react-app/src

💼 Edit your deployment scripts in packages/hardhat/deploy

📱 Open http://localhost:3000 to see the app

🚨📡 To deploy to a public domain, use yarn surge. You will need to have a surge account and have the surge CLI installed. There is also the option to deploy to IPFS using yarn ipfs and yarn s3 to deploy to an AWS bucket 🪣 There are scripts in the packages/react-app/src/scripts folder to help with this.`

FILE MISSING

Please provide assests.js file

"Nonce too low" error from Hardhat-network when using loogies-svg-nft with localhost <Punkwallet.io>

Describe the bug
Unable to confirm mint transaction with error.

To Reproduce
Steps to reproduce the behavior:

1. yarn install, chain, deploy, start from https://github.com/scaffold-eth/scaffold-eth-examples/tree/loogies-svg-nft.
2. Copy to clipboard link from Wallet connect.
3. At <Punkwallet.io> choose "localhost".
4. Grab from faucet.
5. Insert the link and connect the wallet to the app.
6. Mint couple of tokens.
7. The first one I managed to get, but never another one. Metamask works kind of fine. Error from Hh network.

eth_sendRawTransaction

  Nonce too low. Expected nonce to be 1 but got 0.

Expected behavior
Seamless tokens minting while balance allows it.
