DeFi Smart Contract Vulnerabilities Audit Guide

Here are three DeFi smart contract vulnerabilities for an audit report:

1. Double Spend Attack One possible vulnerability in a DeFi smart contract is the Double Spend Attack. In this attack, someone tries to create multiple transactions that are identical to each other, thereby creating a double spend. This can be done by creating a new contract that performs the same action as an existing contract, or by creating new tokens that have been used to create the original contract.

To detect this vulnerability, the auditor can check for duplicate transactions in the blockchain. They should also monitor the amount of gas consumed by each transaction to ensure that the attacker is not using excessive resources.

1. Smart Contract Tampering Another potential vulnerability in DeFi smart contracts is smart contract tampering. This attack involves modifying the contract code to change its behavior or to perform unauthorized actions.
