What are Smart Contracts? Use Cases and Examples

Smart contracts are an important part of most blockchain-based ecosystems, and the most important element of application-focused blockchains, such as Ethereum. These smart contracts are programs that run on blockchains. For instance, an Ethereum contract will run on the Ethereum blockchain.

Smart contracts are digital, autonomous, transparent, trustless, and decentralized — and these contracts normally can not be modified or altered once deployed. One of the advantages of smart contracts include reducing or sometimes removing intermediaries and contract enforcement in a transaction or an agreement. With smart contracts, the code is the final arbiter of the terms as it defines the mechanisms of the transaction. It is because of these reasons that smart contracts are playing a vital role in the world of decentralized applications, also known as dApps, which shows development of blockchain technology in general.

Decentralized Applications

Most decentralized applications work when a number of different smart contracts are brought together to enable a synergistic and a sophisticated set of functionalities. There are so many blockchain networks that facilitate dApp development, which means there are thousands of dApps across these various blockchain networks.

These decentralized applications include exchanges, finance, gaming, and media platforms. These dApps utilize smart contracts in different ways to offer different sets of functions. Important use cases of smart contract applications in the finance sector include trading, investing, borrowing and lending. Smart contracts can also be used for applications in healthcare, real estate and even gaming.

Other than that smart contracts can be used to configure entire corporate structures. Smart contracts have the potential to shape the future of so many different industries. However, we will cover some of the use cases of smart contracts in finance and potential smart contract advantages in other industries.

Smart Contracts

Smart Contracts in Finance

Decentralized finance (DeFi) is to be regarded as a formidable alternative to traditional finance. DeFi solutions continue to grow in popularity because of the trustless, transparent and immutable nature of blockchains and smart contracts. Decentralized applications also provide banking and financial services like lending, bowring, trading and so much more along with completely new types of products and services that offer benefits and utility for users.

Decentralized applications, because of the increased transparency provided by smart contracts and blockchain along with reduced costs and 24/7 functionality, have the potential to lower the barriers for people all around the world who are looking to enter into the financial services sector.

Decentralized Finance projects have already captured billions of dollars in value and are likely to continue this trend as more and more individuals and businesses become familiar with the unique benefits that this sector has to offer. Users can participate in this new generation of financial services without the need for centralized custody or fees from intermediaries. Although the DeFi sector is only a few years old, given the number of innovative dApps that are already providing value and utility to consumers, the effects of smart-contract-powered dApps on the financial industry are already being felt.

Smart Contract in Other Industries

Smart contracts on different blockchains have resulted in various different kinds of real world applications of smart contracts. While most people think Bitcoin is the biggest blockchain based crypto project, smart contracts on other blockchains like Ethereum, Solana or Cardano offer much more benefits than Bitcoin smart contracts.

Currently developers and researchers are eager to make use of the advantages of smart contract technology to address needs of the growing Internet of Things (IoT). Smart contracts and blockchain can offer a high level of security and transparency to IoT devices and offer many more advantages.

Healthcare sector is also starting to integrate blockchain technology for trustless, transparent and secure data sharing. This relationship between blockchain and healthcare could also be further strengthened by the integration of smart contracts and decentralized apps designed for the purposes of solving challenges that exist in the healthcare industry.


With all these applications and use cases of smart contracts we have discussed, combined with the ongoing development of many more, smart contracts are poised for growth.

Organizations and companies in different industries, with the help of smart contract development companies, are looking to utilize the smart contract technology that continues to revolutionize the digital world.
