What is Smart Contract Development?

Smart Contract Development: Smart contract development involves creating and deploying self-executing digital contracts on blockchain platforms. These contracts are programmed to automatically execute specific actions when predefined conditions are met, eliminating the need for intermediaries and enhancing the security and transparency of transactions.

Smart contracts use blockchain technology to automatically enforce and execute themselves when specific conditions are met. There are many applications for smart contract technology, and it is being used in industries such as finance, insurance, real estate, supply chain, and gaming.

In healthcare, for instance, smart contracts are being used to enhance communication between insurers and patients. A patient’s information chart can be stored on a blockchain, allowing authorized users (like medical professionals) to trigger the smart contract for information and insurance coverage. This can cut down on paperwork, simplify information sharing between providers, and improve compliance.

While the applications for smart contracts are practically endless, smart contract development requires a deep understanding of blockchain fundamentals, coding skills, and expertise in smart contract programming languages.

Smart contract development companies are involved in everything from ideation, design, and development through deployment. They are able to create bespoke solutions to make sure your business objectives are met.

They’re also able to integrate smart contracts into decentralized applications (dApps) and can run audits to ensure your smart contracts are reliable and free of vulnerabilities.

As discussed above, smart contracts are being implemented and utilized across industries largely because they can streamline processes, are secure, and are reliable. While they can be used for a variety of tasks, these benefits make smart contract development an attractive option for businesses and individuals looking to streamline and secure their transactions.

Here are some of the most common reasons why companies invest in smart contract development:

  1. Speed and Efficiency: Smart contracts enable immediate execution of transactions, even for complex, multiparty agreements, leading to faster and more efficient processes. For this reason, smart contracts can accelerate processes such as property ownership transfer by autonomously creating and executing agreements upon compliance with specific conditions.
  2. Trust and Transparency: These contracts provide a secure and transparent environment, reducing the susceptibility to manipulation and enhancing trust in transactions. Smart contracts offer transparency in agreements and operate autonomously once predefined conditions are met.
  3. Security: Smart contracts enhance security through their automated and ledger-protected nature, making them less vulnerable to fraud or unauthorized alterations.
  4. Accuracy and Immutability: The automation of smart contracts ensures accuracy in the execution of agreements and their immutable nature provides a solid audit trail.
  5. Cost Reduction: By eliminating intermediaries and automating processes, smart contracts can lead to cost savings in various transactions.

What Services Do Smart Contract Development Companies Provide?

Each smart contract has differing requirements, which requires different development skills and expertise.

However, the development process remains relatively similar regardless of your project’s goals. Here’s what you can expect when hiring smart contract development services:

  • Ideation
  • Choose a Blockchain Platform & Development Tools
  • Begin Smart Contract Development
  • Conduct In-depth Testing
  • Connecting to the Blockchain Network
  • App and API Development
  • Deployment and Maintenance


When you first begin the smart contract development process, you will need to sit down with the development team to discuss the goals of the project. The ideation phase begins with identifying specific challenges or inefficiencies that can potentially be addressed through the use of smart contracts.

Teams engage in creative thinking and idea generation to conceptualize how smart contracts can be leveraged to solve the identified problems. Then they will assess the feasibility of the project. This may involve evaluating technical requirements, resource availability, regulatory considerations, and potential obstacles.

Choosing a Suitable Platform & Development Tools

Once the contract development team has identified the project requirements and assessed the feasibility of the project, they will begin to outline how they will achieve project objectives. To do so, they will need to select an appropriate blockchain network for deploying the smart contract, such as Ethereum or Hyperledger, as well as the necessary tools for development. Integrated development environments (IDEs) are used for writing, testing, and deploying the smart contract code.

Often, smart contract development companies will have an IDE they prefer to work with. Otherwise, they will consider the needs of your project and which platforms would offer the best solution for your goals. The same goes for determining which blockchain network they will deploy your smart contract on. 

Begin Smart Contract Development

The development stage is largely coding, which requires a deep understanding of the specific blockchain platform on which they will operate. Each platform may have its own unique programming language and development environment. For example, Ethereum smart contracts are primarily written in Solidity, a language designed for creating and deploying contracts on the Ethereum Virtual Machine (EVM).

Conduct In-Depth Testing

Thoroughly test the smart contract to ensure its functionality, security, and accuracy under various conditions. Smart contracts, once deployed on a blockchain, are immutable and self-executing.

This means that any vulnerabilities or bugs in the code can lead to irreversible financial losses or unexpected behavior. Thorough testing helps identify and address security flaws before deployment, reducing the risk of exploitation by malicious actors.

Testing ensures that the smart contract functions as intended, accurately executing the specified business logic and contractual agreements. These tests will also ensure that code behaves predictably under different scenarios and edge cases.

Connect to the Blockchain Network

A blockchain network refers to a decentralized, distributed ledger system that enables peer-to-peer transactions and data sharing across the network. For this reason, smart contracts need to be connected to a blockchain network. Many blockchain networks support smart contracts including:

Common Blockchain Networks For Smart Contracts

  • Ethereum
  • Hedera Hashgraph
  • Baseline
  • Hyperledger
  • EOS
  • Polkadot
  • Corda
  • Quorum

Create an App and API

Developing the necessary applications and APIs play a crucial role in bridging the gap between smart contracts and end-users.

This involves creating intuitive and user-friendly interfaces that enable users to easily interact with smart contracts on the blockchain network. Whether it's deploying new contracts, executing functions within them, or querying contract data, these interfaces must be designed with both functionality and security in mind.

Additionally, APIs facilitate seamless communication and data exchange between the smart contracts and external systems or other blockchain layers. This not only enhances the smart contracts' capabilities but also ensures that they can be integrated into broader applications, thereby expanding their utility and potential for innovation.

Deployment and Maintenance

Once the smart contract has been deployed, you may still employ the development company for maintenance. Ongoing maintenance for smart contracts is crucial for several reasons, especially when considering the long-term health and functionality of these blockchain-based agreements.

Regular maintenance and updates to address any changes in business requirements or technological standards. Just like any software, smart contracts can be vulnerable to security exploits or new attack vectors. Ongoing maintenance allows for the implementation of security updates and patches to address newly discovered vulnerabilities and ensure the integrity of the contract.

How to Assess The Performance of Smart Contract Development Partners
