8 Simple Steps to Develop Your Own DeFi Smart Contract

Individuals exploring creativity in the digital realm can explore a wide range of opportunities through smart contract development. Have you ever come across this concept before? It's nothing but the idea of using blockchain to create self-executing agreements that automate actions with certain pre-conditions.

In the same way, DeFi smart contracts use blockchain technology and help users undergo various financial activities and transactions without the need for any traditional intermediaries or middlemen. In recent years, the financial evolution has played a major role in shaping the future of DeFi, and thus has evolved the urge to develop your own DeFi smart contract.

Despite these evolutions, the complexity level of developing a DeFi smart contract is not as easy as you think. It clearly needs a precise blend of technical expertise and insights about financial logic. By following our well-planned development process and having an understandable knowledge of DeFi smart contracts, any individuals can create secure and efficient contracts.

Overview of DeFi Smart Contracts

In simple terms, decentralized finance smart contracts, also known as DeFi smart contracts, are blockchain-based digital agreements that automatically handle various financial activities without the need for any central authorities or intermediaries like banks and brokers. Here, the financial activities include processes like loans, trading, and payments.

The smart contracts are generally written in code format, which automatically executes actions by themselves once the predetermined conditions are achieved or met. However, this process is done in a trustless, transparent, and efficient way with minimal cost and increased speed without any manual intervention.

The DeFi smart contract development process is generally done on various blockchain platforms, with Ethereum being the most popular one and other platforms like Solana, Polygon, and BNB Smart Chain.

How Do DeFi Smart Contracts Work?

A DeFi platform typically works as an automated digital program, where users can interact with a smart contract through a blockchain wallet and execute the contract actions on its own once the predefined conditions are met. Let’s take a closer look at how DeFi smart contracts work.

Code-Based Agreements

The smart contract code is defined and written based on the financial transaction rules. Then, the compiled code is deployed on the popular blockchain network, where it becomes decentralized and transparent.

User Interaction

Users connect with crypto wallets and send transactions to their unique address to perform various activities and to interact with the smart contract. This is carried out automatically without the help of any third parties.

Self-Executing Transactions

Then, the smart contracts self-execute the actions automatically once the predefined conditions are met. For example, if a user deposits collateral to borrow a loan, the smart contract releases the loan and tracks repayments.

Automation & Robust Security

In the following stage, blockchain ensures to record every transaction automatically by reducing risks and potential errors. This way of engagement enables every users to endlessly perform financial operations with high transparency and security, without the need for any centralized authorities.

Reliable & Trustless Transactions

Once the pre-defined conditions are met, smart contracts confirms and settle downs the transactions instanlty on its own. Then, every transactions are recorded immutably on blockchain, providing complete transparency and visibility to the users and eliminates none of the central authorities to control the DeFi functions.

8 Simple Steps to Develop Your own DeFi Smart Contract

Looking to develop your own DeFi smart contract Now? Then, you can make it simple with our 8 effective steps, following with a correct planning and execution.

Step 1 - Define Your DeFi Concept

The first step in building a DeFi smart contract is to clearly define the contract’s purpose. So, explain on which platform your contract operates. It may be lending, borrowing, or staking, or even a decentralized exchange platform.

Then, clearly explain the audience’s target and the key features that you are about to integrate within your smart contract. This will ensure safe, efficient, and fair interaction between users.

Step 2 - Pick a Blockchain

As a secondary process, you need to choose a wise blockchain platform that perfectly aligns with your project needs and goals. Here, the popular choices include Binance Smart Chain, Ethereum, Polygon, etc.

You can confirm your selection by considering parameters like network speed, fee structure, and technical support, and a platform that enhances user adoption seamlessly.

Step 3 - Select the Programming Language

Choose a development language that is compatible with your blockchain network. Here, Solidity and Rust are the commonly used languages for the Ethereum and Solana blockchain networks.

They affect the security and integration opportunities with other decentralized finance protocols. Therefore, choose a wise language and ensure that the respective development team has sufficient expertise.

Step 4 - Develop the Smart Contracts

Now, use frameworks like Hardhat or Truffle to write and simplify your smart contract deployment process. Develop the smart contracts by integrating with planned functions like deposits, withdrawals, and borrowing. Implement the DeFi contracts with proper architecture to effectively handle exploits, vulnerabilities, and other security audits.

Step 5 - Integrate Security Protocols

In the decentralized finance smart contract development process, integrating security measures is one of the crucial steps to prevent financial losses for users.

So, once you have developed the smart contract, use OpenZeppelin to ensure your tokens are handled in a safe way with easy accessibility. This must also protect your contracts from online hacks, attacks, and unauthorized access.

Step 6 - Perform Security Audits

Now, it's important to conduct thorough auditing on your smart contracts to find the hidden bugs and errors. This can be perfectly achieved with the help of security audit professionals, who boost users' experience. Further, any reposted issues and vulnerabilities will be identified in this step, and your smart contracts will be protected securely and reliably before deployment.

Step 7 - Deploy to the Mainnet

Once the security audits are completed, deploy your smart contract on the mainnet on your chosen blockchain. Continuously monitor the launch process closely to find the hidden issues or unexpected behavior. Further, provide intuitive support services and strong liquidity pools to maintain a consistent and smooth DeFi experience for all users.

Step 8 - Continuous Monitor & Updates

After the contract's launch process, continuously monitor its performance, blockchain activity, and suspect any unusual behaviour. Then, track its activities like usage of gas, transactions, etc, and provide regular updates to its users. This final step will ensure your contracts remain efficient, safe, and trustworthy among users.
