💰 MyMultiSig.app Smart Contract (Beta) 🚀

A minimalistic Solidity smart contract designed for secure and streamlined transactions, MyMultiSig.app simplifies the multisig process for an easy and convenient experience 💻. The contract is integrated with the mymultisig.app web app for an enhanced user experience 📱.

🔥 This smart contract is a multi-signature wallet, which means that a certain number of owners need to sign off on a transaction before it's executed. 💰

💻 The code is written in Solidity and uses two external libraries, ReentrancyGuard and EIP712, for added security. 🔒

📈 The contract keeps track of various important details, like the name of the contract, the transaction nonce, the number of owners, and who the owners are. 📝

🎉 The contract also has events for adding and removing owners, changing the threshold, executing and failing transactions, and reaching the end of its life (when the nonce hits a certain limit). 💬

💬 When you're ready to make a transaction, you can call the execTransaction function and pass along the destination address, the amount of Ether to transfer, any data you want to include, the gas limit, and the signatures from the necessary owners. 💸

💻 The signatures are verified using the _validateSignature function, and the transaction is executed using the call opcode in assembly. 💻

🎉 If the signatures are valid and there's enough gas, the transaction is a success and a TransactionExecuted event is emitted. If not, a TransactionFailed event is emitted. 💬

🔒 Advantages of Using MyMultiSig.app

1. Security: 🔒 A multisig contract requires multiple signatures before a transaction can be executed, making it more secure compared to a single signature transaction.

2. Decentralization: 💪 The multisig contract can be managed by multiple parties, promoting decentralization and reducing the risk of a single point of control.

3. Flexibility: 💡 The contract can be customized to fit the specific requirements of different organizations, including the number of signatures required and the threshold.

4. Transparency: 🔍 All transactions executed by the multisig contract are recorded on the Ethereum blockchain, providing a transparent and auditable trail of all transactions.

Note: This smart contract is currently in beta, use at your own risk.

🔧 Install Dependencies

To install all necessary dependencies, run the following command:

yarn

💻 Run Tests

To run tests, you have the option to use either Hardhat or Foundry.

🔨 Hardhat Tests

To run tests using Hardhat, use the following command:

yarn hardhat test

Additionally, you can run a coverage report using Hardhat with the following command:

yarn coverage

🔥 Foundry Tests

To run tests using Foundry, use the following command:

forge test

💥 Hardhat & Foundry Tests

To run tests using both Hardhat and Foundry, use the following command:

yarn test

🚀 Deploy Locally

To deploy the contract locally, you'll need to run a node with Hardhat.

In a first terminal, run the following command to start the Hardhat node:

npx hardhat node

In a second terminal, while the node is active, run the following command to deploy the contract:

yarn deploy-localhost
