Vault_Contract_nextjs-web3

This is a minimalistic project to show us how we can connect to metamask using web3-next in nextjs / web3.js.

This could just as easily be done in typescript.

This project started with nexjs boilerplate by running yarn create next-app nextjs-web3-react-metamask-connect

Getting Started

Requirements

git
- You'll know you did it right if you can run git --version and you see a response like git version x.x.x
Nodejs & npm
- You'll know you've installed nodejs right if you can run:
  - node --version And get an ouput like: vx.x.x
- You'll know you've installed npx right if you can run:
  - npm --version And get an ouput like: x.x.x
Yarn instead of npm
- You'll know you've installed yarn right if you can run:
  - yarn --version And get an output like: x.x.x
  - You might need to install it with npm
Metamask
- This is a browser extension that lets you interact with the blockchain.

Quickstart

Clone and install dependencies

git clone https://github.com//LovelyDodger/Vault_Contract_Next_Web3
cd Vault_Contract_Next_Web3
yarn

Then, you'll need to open up a second terminal and run:

git clone https://github.com//BTC415/Vault_Contract_Next_Web3
cd /LovelyDodger/Vault_Contract_Next_Web3
yarn hardhat node

This will deploy a sample contract and start a local hardhat blockchain.

Connect your metamask to your local hardhat blockchain.

PLEASE USE A METAMASK ACCOUNT THAT ISNT ASSOCIATED WITH ANY REAL MONEY. I usually use a few different browser profiles to separate my metamasks easily.

In the output of the above command, take one of the private key accounts and import it into your metamask.

Additionally, add your localhost with chainid 31337 to your metamask.

Open the UI

Then, back in your first terminal, run:

yarn dev

Hit buttons

You'll be brought to the UI after running yarn dev which has exactly 2 buttons. Hit connect then hit execute and you'll send a transaction to your local hardhat.

Important localhost note

If you use metamask with a local network, everytime you shut down your node, you'll need to reset your account. Settings -> Advanced -> Reset account. Don't do this with a metamask you have real funds in.
