DeFi Security Best Practice

In the area of cryptocurrencies and blockchain technology, decentralized finance (DeFi) has quickly gained popularity. Decentralized financial interaction and transactions are made possible by DeFi protocols, which do away with the need for intermediaries. Many advantages have been created by this ground-breaking technology, including improved security, accessibility, and transparency. The risks associated with DeFi protocols have, however, grown along with their prevalence.

It’s critical to keep up with the most recent trends and advancements in the DeFi market. The problem of DeFi attacks is one that has been getting a lot of attention lately. 

Like any other technology, DeFi has its risks, and these include:

Smart Contract Vulnerabilities: DeFi protocols rely on smart contracts that can be exploited by hackers, resulting in the loss of funds.

Centralized Points of Failure: Although DeFi protocols are decentralized, some still rely on centralized points of failure, such as oracles, which can be attacked.

Liquidity Risks: DeFi liquidity is dependent on market supply and demand, which can result in extreme price volatility, leading to the loss of funds.

Human Error: Human error, such as sending funds to the wrong address or forgetting your private keys, can also result in the loss of funds.

Now that we have gained an understanding of some of the risks and potential attacks associated with DeFi, it is important to consider ways in which we, as users, can protect ourselves against these risks.

1. Conduct thorough research before investing

Doing in-depth research on the project or protocol you intend to invest in is the first step in DeFi security. This includes studying the project’s whitepaper, verifying the team’s credentials, and looking into the security precautions of the protocol. To be sure that the code and smart contracts have been thoroughly examined for vulnerabilities, it is crucial to check for smart contract audits and reviews.

2. Use a hardware wallet

The safest option to store your holdings is in a hardware wallet. By keeping your private keys offline, they give an extra degree of security by preventing remote access to them by hackers. Also resistant to phishing and virus attacks that could compromise your security are hardware wallets.

3. Enable two-factor authentication (2FA)

Where possible, use two-factor authentication (2FA). This is one of the strongest forms of authentication. Besides your password, hackers would also need access to 2FA Authentication mode, which sends you a one-time code through email or phone. Even if your password is stolen, using 2FA reduces the chance of unauthorized access to your account.

4. Keep your software up to date

Outdated software is one of the most frequent reasons for security breaches. To make sure you get the most recent security patches and upgrades, it’s crucial to keep your software up to date. This holds true for your operating system, DeFi wallet, and any other program you use to communicate with DeFi protocols.

5. Be cautious of phishing attacks

Hackers frequently employ phishing attempts to get access to user accounts. These attacks typically involve sending an email or message that looks to be from a reliable source and requests login credentials or personal information. Always be wary of these attacks and keep your passwords and private keys to yourself. Beware of a new type of phishing called ice phishing, which tricks users into signing a malicious transaction, allowing attackers to control their crypto assets.

6. Always review your token approvals & revoke unused ones

Token approvals allow DeFi platforms to access and transfer a user’s tokens on their behalf.  In case of a security breach or hack, the platform can transfer or use the tokens without the user’s consent. Therefore, It is critical to periodically check and revoke access and permissions granted. You can use withdraw. cash to cancel access. In addition, users should also ensure that they are interacting with legitimate and secure DeFi platforms.

7. Never blind-sign transactions

Before confirming the transaction, always examine the permission details in the smart contracts. Many hackers disguise their actions in smart contracts, giving them unauthorized access to funds in your wallet. If possible try to read the smart contract details carefully and validate that they do not provide a threat or vulnerability.


In conclusion, ensuring the security of your assets in DeFi is crucial due to the risks involved with protocols, including smart contract vulnerabilities, centralized points of failure, liquidity risks, and human error. To protect against these risks, users should conduct thorough research, use a hardware wallet, enable two-factor authentication, keep software up to date, be cautious of phishing attacks, diversify investments, and regularly monitor accounts.
