an off-chain signature based multi sig wallet

---

---

🏃‍♀️ Quick Start

required: Node plus Yarn and Git

git clone https://github.com/enepti/meta-multi-sig.git meta-multi-sig

cd meta-multi-sig

yarn install

yarn start

in a second terminal window:

yarn chain

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

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

💼 Edit your deployment script deploy.js in packages/hardhat/scripts

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

in a third terminal window:

yarn backend

🔧 Configure your deployment in packages/hardhat/scripts/deploy.js

Edit the chainid, your owner addresses, and the number of signatures required:

in a fourth terminal deploy with your frontend address as one of the owners:

yarn deploy

Use the faucet wallet to send your multi-sig contract some funds:

To add new owners, use the "Owners" tab:

This will take you to a populated transaction create page:

Create & sign the new transaction:

You will see the new transaction in the pool (this is all off-chain):

Click on the ellipsses button [...] to read the details of the transaction

Give your account some gas at the faucet and execute the transaction

The transction will appear as "executed" on the front page:

Create a transaction to send some funds to your frontend account:

This time we will need a second signature:

Sign the transacton with enough owners:

(You'll notice you don't need ⛽️gas to sign transactions.)

Execute the transction to transfer the funds:

(You might need to trigger a new block by sending yourself some faucet funds or something. HartHat blocks only get mined when there is a transaction.)

💼 Edit your deployment script deploy.js in packages/hardhat/scripts

🔏 Edit your contracts form, MetaMultiSigWallet.sol in packages/hardhat/contracts

📝 Edit your frontend in packages/react-app/src/views

⚔️ Side Quests

🐟 Create custom signer roles for your Wallet

You may not want every signer to create new transfers, only allow them to sign existing transactions or a mega-admin role who will be able to veto any transaction.
