What are Web3 Contracts? Exploring Smart Contracts

Web3 contracts, also known as smart contracts, are crucial in today’s blockchain ecosystem. They enable users to interact online via the blockchain and the many dapps in the Web3 realm. Further, they set the conditions for decentralized transactions without needing a centralized third-party authority for verification. In other words, Web3 contracts govern the rules of any Web3 agreement. Given the importance of Web3 contracts, any aspiring blockchain developer or current Web3 user should understand these vital elements of the crypto realm in greater depth.

Use cases for Solidity smart contracts, or Web3 contracts, include decentralized financial services (particularly in DeFi protocols), decentralized digital identity, and building DAOs (decentralized autonomous organizations). Furthermore, use cases include legal, tokenization, and decentralized gaming applications. 

Gaming, in particular, has become pretty exciting because of the emergence of the Web3 metaverse. Through GameFi and play-to-earn (P2E) concepts, Web3 contracts tie in token or crypto incentives with gameplay. As a result, Web3 contracts are ushering in a new era of combined entertainment and earning potential. 

Writing Web3 Contracts

Do you have enough skill, or are you utilizing the proper Web3 tech stack to write smart contracts? To get started in blockchain development, you mainly need two programming languages: JavaScript and Solidity. Apart from these, you’ll need layers of programmable blockchains, nodes and node providers, development platforms, and APIs.

Today, people mostly use Solidity to write the majority of smart contracts for blockchains such as Ethereum. Moreover, Ethereum remains the most popular blockchain for Web3 contracts. Beginners who want to learn more about Ethereum may refer to the Moralis article on Ethereum development

However, things are not as complicated as they seem. Even if you don’t know how to write Web3 contracts in Solidity, you can still build dapps on Ethereum by relying on free tools such as OpenZeppelin to find a variety of smart contract templates and deploy them using Remix.

The space is innovating fast, and new ways to write and create Web3 contracts are emerging alongside new blockchains. Fortunately, Moralis allows greater flexibility by being cross-chain compatible from the start. As such, you can build cross-chain dapps that are instantly compatible with multiple Web3 blockchains using Moralis.

If you are completely new to Web3 contracts, you can use this article to read up further on smart contracts’ origin and applications. In addition, this guide will expand your knowledge of their major use cases, especially in the context of emerging opportunities in the metaverse. 

What are Web3 Contracts?

Web3 contracts are also called smart contracts. But, what are smart contracts? Smart contracts are agreements between two or more parties over the internet. Moreover, Web3 contracts are the backbone of the Web3 industry, and today’s blockchain-driven internet operates on Web3 contracts. 

Web3 contracts are self-executing agreements. Instead of needing third parties or professionals to implement such agreements, they employ code. These digital contracts enable many functions, including buying, selling, and trading assets. Furthermore, with Web3 contracts, you can exchange various currencies, tokens, or types of property. Moreover, such contracts allow these transactions to be transparent on the blockchain. Being purely digital and programmable, the terms of a smart contract agreement are part of the code itself. Moreover, programmability means that these contracts can be unique and customized with their incentive systems, rules, and penalties.

Let’s now briefly explore the origin of Web3 contracts in the next section.

Origin of Web3 Contracts

The term “smart contract” was first coined over twenty years ago by Nick Szabo, a polymath and cryptography pioneer. He created “bitGold”, which many believe is among the technologies that led to Bitcoin. Being a pioneer in the Web3 realm and coining the term “smart contract”, rumors are stating that Szabo is Satoshi Nakamoto, the developer of Bitcoin.

Smart Contract Variables

To understand how to write a Web3 contract, you need to understand the basic variables. Moreover, you need to define the following variables to create the terms of the smart contract agreement: 

  1. Parties involved in the transaction
  2. Type of asset exchanged
  3. Conditions of the transaction

The third variable means that you need to fulfill certain terms before the Web3 transaction is executed. Hence, this provision eliminates a middleman or authority’s need to get the deal done. Furthermore, this means that even anonymous or pseudonymous transactions are possible.

The requirements for execution are clear-cut. For example, a smart contract for a fund transfer can only run when there is a digital signature, confirmation, deposited amount, etc.

Advantages of Web3 Contracts

What kind of advantages do Web3 contracts provide for users? With its decentralization aspects, these contracts bring new ways to transact online without the need for a middleman (trustlessness). Also, they are autonomous, accurate, interruption-free, and cost-effective. 

However, Web3 contracts have wider implications for developers, users, entrepreneurs, and existing businesses. Smart contracts enable user authentication without a traditional centralized sign-up process that a single entity or company controls. You can enable decentralized authentication via a Web3 wallet such as MetaMask. This setup lets anyone sign up with multiple dapps using a single-user wallet that no one except the owner controls. Moreover, this implies that an entire decentralized economy can be built out of smart contracts and their capabilities.

Web3 contracts can also be used to create DAOs (decentralized autonomous organizations). They can be used to organize a large number of users without the need for a corporate entity. Using the Moralis boilerplate, you can create a DAO in ten minutes. Want to learn more about how to create a DAO smart contract? Make sure to check out the DAO guide at Moralis’ blog!

If you want to build next-gen websites, dapps, or online businesses, Web3 contracts are crucial. You can apply them to accomplish almost anything, or you can integrate them with your existing business model to access new users or add new features. What’s more, you can make any website interact with smart contracts

Web3 Contracts – A Trillion-Dollar Opportunity

Web3 contracts will support an entirely new economy. Further, such an economy won’t resemble the current one we have now, which is still primarily based on Web2 concepts and more centralized authorities. Smart contracts will usher in more distributed opportunities to users all over the world. Moreover, they will launch the careers of many blockchain developers and creators in a new decentralized ecosystem.
