A wallet that requires approval from 2 designated address to complete transactions.

Here is the app running on the Sepolia network

Solidity | React | Hardhat | OpenZeppelin | Viem

Start of by cloning this repo or downloading the zip file. After that open up your terminal and run these commands:

cd ProjectFolder
pnpm install

Next step is to get the Hardhat blockchain node running locally

cd /path_to_project/MultisigWallet/blockchain
pnpm hardhat node

Then test, compile and deploy the contracts

pnpm test
pnpm compile

pnpm hardhat run scripts/deploy.ts --network localhost

Finally get the client site running on localhost with the Hardhat node. We need to change a few things:

Open up /client/src/utils.ts and update the function getPublicClent() to this:

export function getPublicClient() {
    return createPublicClient({
        chain: hardhat,
        transport: http('http://127.0.0.1:8545'),
    });
}

Open a new Terminal window and run:

cd client/
pnpm install
pnpm start

Head over to http://localhost:5173 and start using MultisigWallet!

Note: Make sure to update your Metamask to use the local network as well. Check out step 5 in the MetaMask Developer docs

• Use this link to head over to the live site
• Login with Metamask
• Make sure to change Network to Sepolia on Metamask

• Chose and amount and address to which to send funds
• Make sure wallet balance has enough wei

• Must use one of the 3 approved address to approve transfers
• Quorum of 2 means 2 of the 3 address mush approve a transfer for it go to through
