Calloutcoin.com provides detailed economic analysis on the most important DeFi trends. It empowers investors with the knowledge and insights to help them get out front in the new blockchain and crypto world. Drawing from recent survey results, this article pinpoints and discusses the most important security missteps made by DeFi investors. The guide provides users with specific, actionable steps to help them avoid the biggest traps. It brings together best practices to enhance their security across the board in the DeFi space.
Common Security Missteps in Crypto Investing
DeFi investors largely act under mistaken assumptions that create outsized risk of falling victim to scams and exploits. Clarifying these misunderstandings is important, and so is taking a more effective, holistic approach to security.
Misconception 1: Believing Blockchain Ensures Complete Security
Perhaps the biggest misconception out there is the belief that blockchain technology, by default, ensures total security. Although these technologies hold great promise through transparency and immutability, that doesn’t fully remove the risk. Smart contracts, which govern DeFi applications, can be riddled with vulnerabilities that hackers can take advantage of. In fact, a 2021 study discovered that 50% of tokens that were listed on the Uniswap DeFi protocol were scams. It highlights the critical importance of robust due diligence.
Investors need to understand that blockchain's security features protect the integrity of the data but don't safeguard against poorly written code or malicious intent. Smart contract audits, though a useful tool, are not a failsafe, and with time new vulnerabilities can arise. Thus, expecting to trust only the blockchain’s built-in security is a risky blind spot.
Misconception 2: Assuming Safe Keys Equate to Safe Funds
A second myth is that if private keys are well-protected, funds cannot be stolen. Protecting private keys is just a part of the equation. Many investors do not take into account phishing scams, malware and social engineering – the breeding grounds of crypto hacks and scams. For example, a recent $1.5 billion crypto heist was said to be due to a front-end attack. This lesson teaches us that without proper security procedures, even secure keys may leave your funds at risk.
Finally, investors need to be proactive and implement a layered security approach utilizing strong passwords, hardware wallets and vigilance against common social engineering tactics. Keep your security software current. As always, stay smart online by not clicking on unexpected links and not downloading files from untrusted sources.
Overreliance on Security Measures
Many investors fall into the trap of thinking they can check a single security box and that their assets are safe. This overreliance on a single tool can create a false sense of security and the exclusion, or at least deprioritization, of other key practices.
Misunderstanding the Role of 2-Factor Authentication
Two-factor authentication (2FA) is a great security tool, but it’s not a cure-all. Likely many investors think that just allowing 2FA is sufficient security for their accounts, but that’s not necessarily true. We acknowledge that 2FA can be compromised by social engineering, phishing attacks, or hack SIM swapping, but those are advanced methods. Hence, it’s crucial to utilize 2FA along with other security practices, including password hygiene and hardware wallets.
When employing 2FA, investors need to understand the various types and select the strongest one. Using an authenticator app is more secure than SMS-based 2FA. This is because SMS is susceptible to SIM swapping attacks. Periodically checking 2FA settings and updating them is a helpful practice.
The Importance of Comprehensive Security Practices
Creating a holistic security strategy requires layers of protective elements that each complement the other in reducing overall risks. This means creating complex, one-of-a-kind passwords, activating two-factor authentication, keeping private keys in a protected location, and consistently checking for account irregularities. It means that it’s important to be up-to-date with the newest security threats and vulnerabilities that the DeFi space has to offer.
The safest investors will use hardware wallets that store private keys offline. This practice greatly increases protection from online threats. Emergently, frequently back up your private keys. House them in a safe place to safeguard from hardware damage or theft.
Neglecting Token Management
Tokens are the most ignored but essential part of DeFi security. Unfortunately, most investors wrongly assume that they can just set and forget their token approvals. This lack of consideration ultimately leaves them very vulnerable to frauds and exploits.
The Risks of Unmanaged Token Approvals
When engaging with DeFi protocols, users usually need to give token approvals, which are permissions given to smart contracts to spend the user’s tokens. These approvals can linger long after the end user is no longer continuing to use the protocol. If a user’s smart contract is compromised (think phishing attack or loss of a private key), hackers can use these approvals to drain the user’s wallet.
Even more concerning, in a recent survey, participants reported that only 10.8% of users actively monitor their token approvals. Equally alarming, only 16.3% regularly withdraw approvals to protect against rug pulls and smart contract exploits. That’s a shocking level of awareness and failure to act to avoid avoidable security breaches.
Strategies for Effective Token Oversight
To protect themselves from the dangerous effects of token approvals, investors should actively monitor and revoke unused approvals. You’ll find a few other tools to assist you in making it below. Visit Etherscan’s new token approval checker, and their new dedicated DeFi security dashboards. These tools allow users to view all the token approvals they have granted and revoke any that are no longer needed.
It’s equally important to be careful the first time you approve a token to someone. Prior to approving a transaction, investors need to take the time to understand the underlying smart contract code and what permissions they are authorizing. When in doubt if a protocol looks fishy or opaque in any way, don’t touch it with a ten-foot pole. One of the largest red flags in the DeFi ecosystem is when a program isn't transparent.
Failing to Learn from Historical Mistakes
The DeFi space is moving fast, and new exploitable security vectors come up every day. Those investors who do not study and learn from their own missteps are certainly cursed to repeat them.
Analyzing Past Incidents for Better Security
If we want to improve security in DeFi, we need to learn from previous hacks. Educate yourself on what went wrong in those instances. In 2024 year-to-date, consumers have already lost almost $1.5 billion to hacking and scam-related security exploits. This painful but necessary loss reminds us that we must learn from past mistakes in order to move DeFi security forward. By dissecting these breaches, investors will be better equipped to spot the most common attack vectors to build a protective defense against such threats.
Most DeFi exploits to date have been due to flaws in smart contract code. By engaging with these vulnerabilities, developers will be better equipped to approach their code and produce more secure smart contracts. In much the same way, investors can and should learn to spot red flags that point to a scam or exploit.
Implementing Lessons Learned in Future Practices
Learning from past mistakes is only half the battle. Investors don’t just need to learn those lessons—they need to put them into practice in the future. Protect yourself while using DeFi protocols. Audit token approvals against a checklist and routinely revoke approvals. Keep you up to date on new and emerging security threats.
Only 17.6% of those who said they fell victim to a DeFi scam checked token approvals on a regular basis afterwards. Even worse, 26% of victims didn’t take any action after being scammed. At the same time, 16.4% took the perilous path of investing even further into other DeFi offerings. This type of action only compounds recent losses and adds insult to injury by taking the lessons from a very recent failure off the table. Surprisingly, more than half of the victims said their belief in DeFi either stayed the same or grew stronger after the incident. Despite enormous losses, investors still have strong faith in DeFi. This emphasizes the need to educate them on the specific risks they could face and increase vulnerability awareness.
Further, investors must communicate their experiences back to the rest of the DeFi community. By working together to share knowledge and best practices, we can all do better to foster a more secure ecosystem.
DeFi investing is best enjoyed with a proactive, informed stance towards security. By understanding common misconceptions, implementing comprehensive security practices, managing token approvals effectively, and learning from past mistakes, investors can significantly reduce their risk of falling victim to scams and exploits.
