A Handy Guide To Developing Smart Contracts Successfully

by Henny Kel Tweet - in Startups

Last updated on February 9th, 2023

The terms of a contract between a buyer and a seller can be implemented mechanically through the use of “smart contracts,” which are computer programmes. Blockchains eliminate the need for intermediaries in many circumstances by encouraging the formation of mutual confidence between parties, allowing for the automation of transactions at low cost and with high efficiency.

This tutorial will go through many different aspects of creating smart contracts. First, we’ll give you a rundown of how smart contracts work and the various platforms you may use to build them. Then, we’ll talk about the things you need to think about before starting to build a smart contract. In addition, we will discuss legal and compliance considerations best practices for smart contract deployment and maintenance, and how to build and test smart contracts. Finally, we’ll talk about some possible future advances in the subject and examine some real-world instances of how smart contracts have been employed in various industries.

About Smart contracts

When it comes to storing and executing the code that makes up a smart contract, the decentralized and secure nature of blockchain technology is an ideal foundation. To put it plainly, a smart contract is an agreement between two parties that is codified as a computer programme and then saved and copied on a blockchain. When the terms are satisfied, the contract goes into immediate effect.

There are a variety of platforms available for the development of smart contracts, each with its own set of benefits and use cases. When it comes to smart contract development, one of the most popular environments is Ethereum, an open-source blockchain platform that allows developers to easily build dapps and smart contracts. EOS, like other well-liked platforms, makes it easy to develop robust decentralized applications (dapps) and smart contracts. However, Hyperledger is an open-source blockchain platform designed specifically for enterprises and public sector organizations.

Financial transactions, supply chain management, and real estate negotiations are just some of the potential business activities that may be automated with the help of “smart contracts.” Ethereum is well-suited for usage in decentralized apps and smart contracts due to its adaptability and programmability. However, EOS is optimized for low-latency, low-cost transactions, making it a prime choice for high-performance decentralized applications (dapps) and smart contracts. Conversely, Hyperledger shines in institutional contexts like business supply chain management, banking, and healthcare.

Planning and Designing a Smart Contract

Many factors should be taken into account during the smart contract’s planning and design phases to guarantee its efficacy and safety.

The first step in creating a smart contract is identifying its boundaries. Included in this are the names and addresses of all parties to the agreement, as well as a detailed description of the terms and conditions under which the agreement would operate. Possible threats should be thought out, and countermeasures should be mapped out.

To continue, think about the smart contract’s framework and features. To do this, one must determine not only the language to be used in creating the contract, but also the precise tasks that it will carry out. The contract’s general design, including its data storage and retrieval mechanisms, should also be taken into account.

Thirdly, security is a critical aspect in the design of Smart Contract Blockchain Development. The code for smart contracts needs to be inspected and tested extensively to find security flaws and correct them. A malicious attack should also be anticipated.

Last but not least, a smart contract’s design should take into account how easy it will be to scale and update. To keep up with the ever-increasing volume of transactions, smart contracts need to be built with easy updating and maintenance in mind.

Defining the smart contract’s scope, thinking about the contract’s structure and functionalities, giving security priority, and making plans for scalability and maintainability are all crucial steps in the planning and design process.

Coding and Testing a Smart Contract

Writing the code that specifies the terms of a smart contract in a programming language that is compatible with the blockchain platform on which it will run is what is meant by “coding” a smart contract.

Solidity, which is used mostly on the Ethereum blockchain, and Vyper, which is also used on the Ethereum blockchain, are two of the most popular programming languages for smart contract development. Solidity is based on existing languages like C++, JavaScript, and Python while Vyper is claimed to be ‘Pythonic’ — a term familiar to Python programmers.

Before a smart contract can be performed on the blockchain, the code must be written in a text editor and compiled into bytecode. The contract is ready for deployment on the blockchain after compilation is complete.

Deployment should only occur after the smart contract has been thoroughly tested and debugged to ensure it is working as expected and that any bugs have been rectified.

These are some of the best methods for verifying and fixing bugs in smart contracts:

  • The creation of extensive unit tests to examine the contract’s features.
  • You may ensure the contract will work as intended by putting it through its paces in a simulated or practice blockchain.
  • Using manual testing to find bugs that the automated testing process missed.
  • Keeping a close eye on the contract’s source code and testing results to find and solve any security flaws.



In conclusion, a smart contract is an effective tool that may automate many procedures and significantly reduce the number of middlemen. The fundamentals of smart contract technology, the available development platforms, the smart contract’s design and planning, its coding and testing, as well as the legal and compliance considerations involved, have all been discussed in this lesson.

Among the many takeaways from this guide are the importance of managing expectations, planning the right contract’s architecture and operations, the huge importance of security, and better expansion and upkeep. The development process is not complete without incorporating testing and debugging actions to ensure the contracts are functioning as advertised.

Smart contract development is now a maturing industry and is expected to expand its frontiers soon. As more companies adopt blockchain, one can expect smart contracts to play an important role in several business systems. Expect the future to hold more promise for smart contracts as they improve in stability, scalability, and compatibility. Smart contracts will almost become standard practice for several industries, including logistics, finance, legal, and healthcare industry.
