Overview of this book

Solidity is among the most popular and contract-oriented programming languages used for writing decentralized applications (DApps) on Ethereum blockchain. If you’re looking to perfect your skills in writing professional-grade smart contracts using Solidity, this book can help. You will get started with a detailed introduction to blockchain, smart contracts, and Ethereum, while also gaining useful insights into the Solidity programming language. A dedicated section will then take you through the different Ethereum Request for Comments (ERC) standards, including ERC-20, ERC-223, and ERC-721, and demonstrate how you can choose among these standards while writing smart contracts. As you approach later chapters, you will cover the different smart contracts available for use in libraries such as OpenZeppelin. You’ll also learn to use different open source tools to test, review and improve the quality of your code and make it production-ready. Toward the end of this book, you’ll get to grips with techniques such as adding security to smart contracts, and gain insights into various security considerations. By the end of this book, you will have the skills you need to write secure, production-ready smart contracts in Solidity from scratch for decentralized applications on Ethereum blockchain.

Sending ETH from a multisig contract

Now, let's learn how to send ETH from a multisig contract to any public EOA/contract address. We will replicate the example that we discussed in the first section of this chapter, Understanding multisig wallets.

We have deployed a multisig contract before. Initially, the multisig has zero ETH balance in it. First, we need to deposit some ETH into the multisig contract. To do this, click on the Deposit button, as shown in the following screenshot and follow the instructions to send ETH:

The multisig contract, its address, and its current ETH balance

You can also send ETH directly to your multisig contract address. Once you have deposited/sent ETH to the multisig contract, you will be able to see the available ETH balance, as shown in the preceding screenshot. Here, we have deposited 2.00 ETH into the multisig contract.

Now that we...
