Decentralized MultiSig

This is a Multiple Signature Wallet built with Hardhat.

Project Layout

There are three top-level folders:

  1. /app - contains the front-end application
  2. /contracts - contains the solidity contract
  3. /scripts - contains a script for deploying the contract

Setup

Install dependencies in the top-level directory with npm install.

After you have installed hardhat locally, you can use commands to test and compile the contracts, among other things. To learn more about these commands run npx hardhat help.

Compile the contracts using npx hardhat compile. The artifacts will be placed in the /app folder, which will make it available to the front-end. This path configuration can be found in the hardhat.config.js file.

Running on a Local Blockchain

The easiest way to get up and going is to run against a localhost blockchain. You can spin one up with ganache-cli or npx hardhat node.

After that, run npx hardhat run scripts/deploy.js --network localhost to deploy the MultiSig Wallet on this local blockchain. This will create a __config.json inside of the ./app folder which will tell the front-end application to point at the deployed contract address.

Front-End

To run the front-end application run npx parcel app/index.html from the top-level directory.

You can learn more about Parcel here.

Connect Local Blockchain To MetaMask

In MetaMask, select the 'Networks' tab, then select 'Custom RPC' - then fill in:

  • Network Name: you can name this anything you like
  • RPC URL: http://127.0.0.1:8545/
  • Chain ID: 31337

Select 'Save' then import a private key into MetaMask from your local blockchain and you are a go!
