1. Choose a Platform

The first step in writing a smart contract is to choose a platform on which to build it. There are several platforms available, including Ethereum, EOS, and TRON, each with its own strengths and weaknesses. Choose a platform that best suits your needs and has the features and tools that you require.

2. Determine the Purpose of the Contract

Before you begin writing your smart contract, it is important to determine its purpose. This will help you to identify the specific functions and features that your contract will need to have in order to achieve its goals. Consider what problem you are trying to solve and what actions you want the contract to perform.

3. Write the Contract Code

Once you have determined the purpose of your contract, you can begin writing the code. The code should specify the terms of the contract, including the conditions that must be met in order for it to be executed. You can use a variety of programming languages to write smart contracts, including Solidity (for Ethereum), C++ (for EOS), and TRON's native language, Solidity. It is important to write clear and concise code that is easy to understand and debug.

4. Test the Contract

Before deploying your smart contract, it is important to thoroughly test it to ensure that it functions as intended. This can be done using a variety of testing tools, such as Ethereum's Remix IDE, that allow you to simulate the execution of the contract and verify its results. It is also important to perform security audits to identify and address any potential vulnerabilities or exploits in your contract code.

5. Deploy the Contract

Once you have thoroughly tested your contract, you can deploy it to the blockchain. This will make it available for use by others on the network. When deploying a contract, you will need to specify the conditions under which it will be executed, as well as the parameters for its execution. It is important to thoroughly review and understand the deployment process for the platform you are using, as well as any associated costs and fees.


Writing a smart contract can seem intimidating at first, but it is a straightforward process that involves several steps. By following these steps and using the right tools, you can create a secure, transparent, and automated smart contract that can help you to achieve your goals. As the technology continues to evolve, it is likely that the process of writing and deploying smart contracts will become even more streamlined and accessible.
