The blockchain technology has already proven its worth by providing unprecedented security and transparency. Preconceptions and biases towards blockchain are fading as it continues to transform traditional industries in numerous ways, including smart contracts.

Contrary to popular belief, smart contracts can be used not only for storing and trading cryptocurrencies. However, that is, indeed, the most common use case. Businesses across various industries, such as healthcare, logistics, and finance, turn to companies providing blockchain application development services to streamline processes and boost their productivity.

In this article, we are looking at five real-life smart contract applications besides cryptocurrencies.

What are Smart Contracts?

A smart contract is a code that is automatically executed when the predetermined conditions are met. They include all the terms from both parties in the encoded format. In case one of the parties violates the agreement, the products or services are returned to the other party. Basically, smart contracts are digital equivalents of traditional paper-based ones.

The use of smart contracts brings businesses numerous benefits. First of all, smart contracts streamline and automate many everyday processes. Within the blockchain, transactions and other operations can be carried out within seconds. Secondly, they eliminate the need for intermediaries due to the blockchain’s decentralized nature. This means there’s no need for fee-charging third parties, such as regulating authorities and government officials, to settle disputes or control the process. Thirdly, the system is immutable and transparent. All modifications are approved by the authorized members and can be easily traced. All of the aspects mentioned above result in reduced transaction time and costs.


Smart contracts play an integral part in the sphere of FinTech and banking. They automate the complex verification and documentation processes typical for the financial industry. This simplifies procedures by automating the tracking of disbursements and repayments. Moreover, the use of smart contracts streamlines identity verification and accelerates cross-border and peer-to-peer transactions.

Another aspect of the financial sphere that smart contracts have enhanced is DeFi (decentralized finance). They lie at the heart of DeFi protocols, facilitating token swapping on decentralized exchanges and direct peer-to-peer lending. Smart contracts also automate the process of rewarding liquidity providers, thus promoting yield farming.

Supply Chain Management

Smart contracts in supply chain management ensure secure tracking of goods from production to delivery. They also help to verify the authenticity of products and combat counterfeiting. Furthermore, by providing an immutable and transparent record of transactions, smart contracts build trust between participants and contribute to a more streamlined organization of global supply chains.

Smart contracts can also be helpful in inventory management. They assist in real-time accurate inventory records management, minimize problems of undersupply or overproduction, and automate everyday processes.


Smart contracts benefit the insurance sector by accelerating the claims settlement process and ensuring timely payments to policyholders. This makes the process more smooth, user-friendly, and efficient and helps resolve any arising disputes quickly. Smart contracts also assist in countering fraudulent activities by offering a mechanism to evaluate claims according to predefined criteria.


The healthcare industry benefits immensely from the implementation of blockchain and smart contracts. Smart contracts facilitate clinical trials by recording data securely, ensuring its authenticity, and providing transparent results. They also optimize patient health data management by providing secure and prompt access for authorized medical professionals.

Smart contracts can be useful in automating medical billing processes, eliminating errors, and preventing data tampering. Smart contracts in telemedicine applications guarantee data safety and integrity, ensure secure transactions, and facilitate a smooth workflow.

Real Estate

In real estate, smart contracts minimize extensive paperwork, facilitate property transfers, and speed up transactions. Blockchain’s immutability provides a clear property ownership sequence, which is often the subject of title disputes. Regarding renting, smart contracts automate such processes as rent collection and ensure compliance with lease terms.

Smart contract-based agreements offer an easy, reliable, and secure way to buy or rent a property. You can use them to transfer rent agreements and property ownership automatically. The technology also eliminates mediators, such as brokers and lawyers, offering a way to cut registration and legal consultation costs.

Final Thoughts

As you can see, smart contracts are in demand in different fields, as they offer unique ways of solving problems. They have become a go-to solution for businesses wishing to enhance security and productivity, all the while cutting costs. Many industries, such as real estate, healthcare, finance, gaming, retail, etc., have already enjoyed the benefits of smart contracts. Technology can enter and transform almost any sphere that requires virtual agreements. We will definitely see how smart contracts revolutionize the existing industries and shape their future. However, security is the most critical concern about the global adoption of blockchain. The technology is still evolving, so ensuring security and complying with regulations should be the number one priority for any business implementing blockchain and smart contracts.
