What are Smart Contracts? 

Smart contracts are essentially programs that are stored and run on blockchain networks like Ethereum, BNB Smart Chain (BSC), Polygon, and Solana. These programs autonomously execute whenever predetermined terms are met, making them ideal for automating the execution of agreements between two or more participants where everyone involved can be sure of the outcome. Moreover, since code handles these agreements, there’s no need for any middlemen or intermediary involvement.

Most smart contracts generally consist of two central parts: a collection of code and data. The code comprises the functions of the smart contracts; meanwhile, the data is its state. Furthermore, each contract’s code and data reside on a particular address on a blockchain network. 

An alternative way to look at smart contracts in simpler terms is to use a metaphor and view them as digital vending machines. This is quite an accurate analogy, and it aptly captures the essence of smart contracts. These programs always deliver a specific output upon completing a predetermined input process – much like inputting money, selecting a product, and receiving the chosen item in the case of conventional vending machines.  

Nevertheless, that covers the basics of smart contracts. To dive deeper into this topic, check out our article called ”What are Smart Contracts?”.

What are the Benefits of Smart Contracts? 

There are many benefits to using smart contracts, and in this section, we’ll explore four prominent examples: 

• Autonomy: Smart contracts remove the need for trusted intermediaries, enabling a higher degree of autonomy when it comes to transactions and other processes.  
• Trust & Transparency: Since there’s no third-party involvement and because transaction records are shared across the blockchain network, there’s no need to question whether the information has been altered for personal gain. 
• Efficiency: As soon as a condition is met, the contract wastes no time and executes immediately. Moreover, since smart contracts are digital and automated, they minimize the potential for human error. 
• Savings: With smart contracts, intermediaries don’t need to handle transactions, which removes associated time delays and unnecessary fees. 

Now, with an overview of smart contracts and their benefits, let’s explore some use cases, ideas, and examples! 

7 Smart Contract Use Cases, Ideas, and Examples 

There are countless ideas and examples of how to use smart contracts, and we won’t be able to cover them all in this article. As such, we have narrowed it down to seven prominent examples: 

1. Finance: Optimize Efficiency and Reduce Costs
2. Real Estate: Track Property Details and Renting
3. Healthcare: Protect Sensitive Medical Records
4. Logistics: Improve Supply Chain Management and Shipping
5. Insurance: Optimize Insurance Claims
6. Music: Improve Copyright Management and Ticket Systems
7. Gaming: Automate Transactions and Add New Features

So, without further ado, let’s dive into the first example and look at ideas of how smart contracts can be used in the finance sector! 

Finance: Optimize Efficiency and Reduce Costs 

Smart contracts can remove costly errors and automate workflows within the traditional finance sector. Furthermore, smart contract technology has paved the way for decentralized finance (DeFi) platforms to provide financial services without unnecessary intermediaries to optimize efficiency and minimize costs. 

The Web3 industry already features multiple established DeFi platforms like AAVE and Curve Finance that use smart contracts to provide advanced services such as borrowing, lending, derivatives, etc. And if you’d like to explore some prominent examples, check out the DeFi tools page on Moralis’ Web3 Wiki!

Real Estate: Track Property Details and Renting 

Two potential ideas for using smart contracts in the real estate industry include expediting property ownership changes and optimizing rental processes! 

For instance, when a buyer pays the seller, a smart contract can autonomously shift property ownership based on the information on-chain. This can significantly improve transaction speed and efficiency by reducing the need for brokers and lawyers. 

Properties can also be rented using smart contracts. And they can be programmed with sophisticated logic. For example, if a maintenance order is submitted on-chain, the smart contract can realize this and lock rent until the issue is resolved.

Healthcare: Protect Sensitive Medical Records 

Healthcare institutions can leverage blockchain technology and smart contracts to reliably automate processes and implement solid security measures. For example, a medical provider can use smart contracts to securely store sensitive data on a blockchain network while simultaneously allowing patients to access and retrieve their own information. That way, patients can make sure that their medical provider has access to the information they need to provide care and that it’s kept securely.  

Logistics: Improve Supply Chain Management and Shipping 

Two promising ideas for using smart contracts to improve logistics are to optimize supply chain management practices and shipping processes! 

For instance, when it comes to supply chain management and shipping, an item effectively changes ownership status once it reaches its final destination, meaning it’s essential to follow the flow of goods. And this process can be optimized through smart contracts. 

By using smart contracts, everyone in the supply chain can track the location of goods as immutable information is stored on-chain. That way, if an item is lost during the process, it’s easy to locate where the error occurred.

Smart contracts can also be used to automate routine payments and tasks so that supply chain members don’t need to waste time with unnecessary communication.

Insurance: Optimize Insurance Claims 

Smart contracts can be used within the insurance industry to automate claims management and reduce fraud. For instance, there are organizations that have been using smart contracts to deal with flight delay insurance claims. In this case, the contract was connected to an air traffic database, and when it detected a two-hour delay, payments were automatically triggered. 

All in all, automating and optimizing claims management in this way shortens processing times and reduces costs. In return, this could result in lower prices and rates for consumers.

Music: Improve Copyright Management and Ticket Systems 

Two ideas and examples for using smart contracts in the music industry are to improve copyright management and ticket systems! 

For example, smart contracts can simplify and facilitate royalty payments for artists and bands. They can be used to record the ownership and other aspects of digital copyrights, including the percentage of royalties that should go to labels, artists, etc.

Event organizers or ticketing services can use smart contracts to create NFT tickets. This can solve issues such as extremely high markups on second-hand tickets by restricting resale prices or adding terms in the contract that ensure that the artists get a part of the profit. 

Gaming: Automate Transactions and Add New Features 

Smart contracts can be used in the gaming industry for new monetization and fan engagement opportunities. For instance, with smart contracts, it’s possible to automate common transactions and add new features, such as players buying and selling in-game items, initiating specific actions, breeding characters, etc.

Some common examples of Web3-based games using smart contracts include Axie Infinity and CryptoKitties. Axie Infinity is one of the most popular play-to-earn (P2E) games where players can sell land, breed characters, and claim rewards. CryptoKitties is one of the first blockchain-based games, allowing players to collect, breed, and trade virtual kittens.

Nevertheless, the topics and examples featured in the list above are only seven prominent ideas, and when it comes to smart contracts, you have a lot of room for creativity!
