Common mistakes to avoid in DeFi smart contract development
Smart contracts are software programmes on blockchain that run when precise goals and objectives are fulfilled or met. They help automate several functions on the blockchain and ensure seamless, flawless, and secure blockchain transaction execution. They are integrated into the blockchain as they allow for better and more transparent conduct of transactions without ambiguity. Smart contracts have been in use for quite some time and have brought immense changes. Today, DeFI smart contract development is on the rise as a result and is experiencing more demand.
DeFi smart contracts help simplify and automate several business functions and trade processes between the trading parties without the need for middlemen. A smart contract scales down on the crypto trade formalities and transaction costs without reducing the authenticity and credibility of the deal. So, what are some of the common or regular mistakes that happen in DeFi smart contract development? Let us unearth the details in the blog below.
What is decentralised finance smart contract development?
DeFi, or decentralised finance smart contract development, is the process of creating smart contracts on a blockchain network. The process is used to securely and transparently handle all crypto and digital currency transactions. DeFi smart contracts are adopted while building decentralised cryptocurrency exchanges, lending platforms, and several blockchain financial apps.
Decentralised finance smart contract development involves the creation, auditing, and implementation of smart contracts that automate all decentralised finance services on the blockchain with no central control. The smart contracts reduce the time needed to complete financial transactions like lending, investing, insurance, banking, etc. They lead to better efficiency and productivity as all actions are fast, accountable, and transparent.
The biggest and most common mistakes to avoid in DeFi smart contract development
Reentrancy attacks. What are reentrancy attacks?. They are a common DeFi smart contract vulnerability or mistake that can be handled with skill and expertise. Reentrancy attacks occur when a smart contract calls another smart contract in its code. When the new call is over, it goes ahead with execution. This needs a vulnerability contract to submit another external call. There are many cybercriminals involved in blockchain scamming who try to commit fraud using external calls. They do this by making a recursive call back to the smart contract with the help of the callback function. The fraudsters can create a contract at an external address using malicious code. This is easily avoidable by following Solidity’s
Simple logic errors. The logic errors are a common type of DeFi smart contract development mistake. They have typographical errors, misinterpretation of specifications, and code programme mistakes that make DeFi smart contract security vulnerable or exposed. These mistakes are easily solved in the DeFi smart contract auditing stage. It is highly advised not to ignore this crucial step while deploying the DeFi smart contracts on the blockchain.
Gas limits mistakes. The gas limits help ensure that blocks don’t grow too large. If a transaction takes too much gas, it cannot fit the block and is not executed. The block gas limit must be set with clear certainty. In cases where data is kept in arrays and accessed via loops using the arrays, the transactions may have insufficient gas and get refunded. This automatically leads to a denial-of-service (DoS) attack.
There are still many other common mistakes in the DeFi smart contract development process, like token investment without research, having less knowledge of liquidity pools, rushing development, and neglecting the thorough testing phase.
