Smart contracts are executed with the terms of the agreement between buyer and seller. The blockchain network enforces the code and the agreements contained therein. Smart contracts enable the automation of contract execution, potentially reducing the necessity for intermediaries and increasing the speed and efficiency of executing a contract.

In the past, smart contracts were mainly used in cryptography and were primarily theoretical. However, with the advent of blockchain technology and decentralized platforms like Ethereum, smart contracts have gained practical relevance and are being used in various applications.

In summary, smart contract development is a digital development that can be automatically executed when certain conditions are met. They can revolutionize the way we execute contracts and conduct business. Here are some stats about them,

  • As a result of a Compound Annual Growth Rate (CAGR) of 24.2% during 2022-2028, the global Smart Contract market is expected to reach USD 1460.3 million by 2028, up from USD 315.1 million in 2021. 
  • In Q1 2022, 1.45 million smart contracts were created. This represents a 24.7% increase over the total number of smart contracts built in Q4 2021, which was 1.16 million.

How Do Smart Contracts Work?

Smart contracts operate on the principle of “if this, then that.” When certain conditions are met, specific actions are taken. Here’s a simple example of how smart contracts work:

#1 Alice wants to sell her car to Bob, and they agree on $10,000. They also agree that the payment will be made in two installments, with the first installment of $5,000 to be paid upfront and the second to be paid after Bob has received the car and inspected it.

#2 To execute this contract, they can use a smart contract. The smart contract will contain the terms of the agreement, including the price, payment schedule, and the transfer of ownership of the car.

#3 When Bob pays the first installment of $5,000, the smart contract will automatically verify that the payment has been made. Once the payment has been confirmed, the smart contract will release the funds to Alice and transfer ownership of the car to Bob.

#4 Once Bob has received and inspected the car, he can pay the second installment of $5,000. The smart contract will again verify the payment and release the funds to Alice.

In this example, the contract is an intermediary, automating the contract execution and ensuring that the agreement terms are.

Smart contracts can be used in many applications, including supply chain management, real estate, and voting systems. They can help businesses conduct business and execute contracts by increasing efficiency, reducing the need for intermediaries, and ensuring that the terms of the agreement are followed.

Examples of Smart Contracts in Action

Here are a few instances of how smart contracts are being used in various industries:

Supply Chain Management

Smart contracts can automate the tracking of goods as they move through the supply chain. For example, a smart contract could automatically release payment to a supplier once a shipment of goods has been received and verified.

Real Estate

They can be used to automate the process of buying and selling property. For example, a smart contract could automatically transfer property ownership to the buyer from the seller once the agreed-upon purchase price has been paid.

Voting Systems

Smart contracts can enable secure and transparent voting systems. For example, a smart contract could be used to store votes in a safe and immutable manner, ensuring that the results of an election are accurate and cannot be tampered with.

Predictive Markets

They can create prediction markets where users can buy and sell shares in the outcome of an event. For example, a smart contract could be used to automatically pay out to users who correctly predicted the result of an election.


Smart contracts can automate making and receiving insurance payments. For example, a smart contract could automatically pay out to policyholders in the event of a natural disaster once certain conditions have been verified.

Advantages and Disadvantages of Smart Contracts

#1 Advantages


Smart contracts automate the execution of contracts, reducing the time it takes to complete a contract from weeks or months to just a few hours.


Smart contracts can eliminate the need for intermediaries, such as lawyers and brokers, reducing costs and increasing efficiency.


Smart contracts can reduce the risk of errors and misunderstandings, as the contract terms are written directly into the code.


Smart contracts are stored on the blockchain, a secure and immutable ledger. This means that the contract terms cannot be altered once they have been agreed upon.


Smart contracts are transparent, as all parties can see the contract terms and actions.

#2 Disadvantages


Creating a smart contract requires a solid understanding of programming and blockchain technology.


Once a smart contract has been created, it can take time to change it. This inflexibility can be a drawback in situations where the terms of the contract need to be amended.

Lack of Legal Recognition

In some jurisdictions, smart contracts may not be legally recognized as enforceable agreements, which can create uncertainty and make it difficult to enforce the terms of the contract.

Limited Programming Languages

Currently, smart contracts can only be written in a few programming languages, which can limit their use.

Overall, while smart contracts have the potential to revolutionize the way we conduct business and execute contracts, they also have some limitations and challenges that need to be addressed.

The Future of Smart Contracts

The use of smart contracts is expected to proliferate in the coming years as more and more industries discover the benefits of automation and the potential for cost savings and increased efficiency.

#1 Financial Industry

Smart contracts can automate the clearing and settlement of financial transactions, reducing the need for intermediaries and increasing the speed and efficiency of the process.

#2 DeFi Platforms

Smart contracts are also expected to play a role in developing decentralized finance (DeFi) platforms, which allow users to access financial services without the need for traditional intermediaries. DeFi platforms are built on the blockchain and rely on smart contracts to enable peer-to-peer transactions and automate the execution of contracts.

#3 Supply Chain Industry

Smart contracts can automate the tracking of goods as they move through the supply chain, reducing the risk of errors and increasing transparency.

Overall, the future of smart contracts looks bright as more and more industries discover the benefits of automation and the potential for cost savings and increased efficiency.
