The promise of decentralization has long been hailed as the future of digital finance — a trustless, transparent, and censorship-resistant alternative to traditional financial systems. Nowhere is this vision more actively pursued than in the world of decentralized exchanges (DEXs). However, a recent report from Cer Live, a DeFi analytics and ranking platform, reveals a troubling reality: most DEXs fall short when it comes to security.
Despite their reputation for being safer due to the absence of centralized control, the study found that 92% of the top 25 DEXs lack sufficient security measures, leaving users exposed to fraud, poor code practices, and operational vulnerabilities.
Security Scores Reveal Widespread Weakness
Cer Live evaluated the top 25 decentralized exchanges based on a comprehensive set of security criteria, assigning each a score from 1 to 10. According to their framework:
- A score above 8 is considered high
- Scores between 6 and 8 are labeled good
- Anything below 6 is classified as low, meaning the platform is deemed unsafe
Shockingly, only two DEXs — Uniswap and Synthetix — received high security ratings. Fourteen of the 25 platforms scored in the "low" range, indicating serious shortcomings in their security infrastructure.
The evaluation criteria included:
- Whether the platform underwent independent security audits
- Availability of public audit reports
- Implementation of bug bounty programs
- Code update practices and re-auditing after changes
- Transparency around token listings and trading pairs
- Transaction slippage and confirmation delays
These factors are critical for protecting users in an environment where smart contracts handle millions — sometimes billions — of dollars with no possibility of chargebacks or customer support intervention.
Audit Gaps and Outdated Code Put Users at Risk
One of the most alarming findings was the lack of proper security audits across the ecosystem. The report states that 6 out of 25 exchanges (24%) either never underwent an audit or failed to disclose one publicly.
“It must be emphasized: a DEX without a public security audit cannot be considered safe.”
Even among those that were audited, many did not re-audit their systems after significant code updates. In fast-moving DeFi environments, new features and upgrades are frequent, but without re-evaluation, previously secure code can introduce exploitable vulnerabilities.
Additionally, some platforms relied on audits conducted by individual researchers rather than reputable cybersecurity firms. Cer Live strongly discourages this practice, noting that professional teams bring standardized methodologies, deeper testing capabilities, and accountability that freelancers often lack.

Fraud Over Hacks: The Real Threat to DEX Users
Interestingly, while no major DEX has suffered a large-scale hack comparable to breaches seen on centralized exchanges, users are far more vulnerable to fraudulent activities.
The report highlights that user deception — such as fake tokens, misleading liquidity pools, and manipulated price feeds — is now the dominant threat vector in decentralized trading.
Unlike centralized platforms where listings are vetted and monitored, many DEXs allow permissionless listings. While this supports innovation and open access, it also opens the door to scams. For example:
- Rug pulls: Developers launch a token, attract liquidity, then drain funds and disappear.
- Spoofed tokens: Malicious actors create near-identical copies of popular tokens to trick users into swapping.
- High slippage exploits: Poorly designed pools enable attackers to manipulate prices during trades.
These issues are compounded by unclear or missing data about listed trading pairs, making it difficult for average users to verify legitimacy.
Why Security Matters More Than Ever in DeFi
Decentralized finance has grown exponentially over the past few years. With total value locked (TVL) in DeFi protocols surpassing tens of billions of dollars, the stakes have never been higher. Yet, as adoption increases, so does the incentive for bad actors.
Users often assume that because a platform runs on blockchain — a technology associated with transparency and immutability — it must be secure. But smart contract code is only as strong as its weakest line, and without rigorous testing, even small bugs can lead to massive losses.
Cer Live’s findings underscore a critical gap: while DEXs excel in decentralization and accessibility, they frequently neglect foundational security practices that protect users.
This imbalance threatens the long-term credibility of DeFi. If everyday investors continue to lose funds through avoidable flaws or scams, trust in the entire ecosystem could erode.

Key Takeaways for Safer Trading
To improve safety across the DEX landscape, Cer Live recommends that all platforms adopt industry best practices:
- Conduct regular audits with established cybersecurity firms
- Publish all audit results transparently
- Launch bug bounty programs to incentivize white-hat hackers
- Re-audit after every major code deployment
- Provide clear information about token listings and liquidity sources
- Implement front-running protection and slippage controls
For users, due diligence is essential. Always check whether a DEX has been audited, review its audit reports, and avoid platforms with anonymous teams or unclear governance models.
Frequently Asked Questions (FAQ)
Q: What makes a DEX secure?
A: A secure DEX undergoes regular third-party audits, publishes its findings, maintains strong code integrity, offers transparency around token listings, and actively monitors for vulnerabilities through bounty programs or automated tools.
Q: Are decentralized exchanges safer than centralized ones?
A: Not necessarily. While DEXs eliminate single points of failure and reduce hacking risks associated with custodial wallets, they expose users to different threats like smart contract bugs, fake tokens, and phishing scams. Overall safety depends on implementation quality.
Q: How can I check if a DEX has been audited?
A: Look for audit reports on the project’s official website or GitHub repository. Reputable platforms typically link to reports from well-known firms like CertiK, OpenZeppelin, or Trail of Bits.
Q: Why do some DEXs skip security audits?
A: Some teams prioritize speed-to-market over safety, especially in competitive environments. Others may lack funding or technical awareness. However, skipping audits significantly increases risk for both developers and users.
Q: Can a high TVL (Total Value Locked) indicate a DEX is safe?
A: Not always. High TVL may reflect popularity or yield farming incentives rather than security. Many exploited protocols had substantial TVL before collapsing due to undiscovered vulnerabilities.
Q: Is Uniswap really the safest DEX?
A: Based on current data from Cer Live, Uniswap ranks among the top due to multiple audits, transparent operations, and robust community governance. However, no system is immune to risk — continuous vigilance is required.
Final Thoughts
The decentralized exchange revolution is still in its early stages. While platforms like Uniswap and Synthetix set strong examples, the broader ecosystem must catch up in terms of security maturity. As DeFi continues to attract mainstream attention, prioritizing user protection isn't just ethical — it's essential for sustainable growth.
For traders and investors navigating this space, awareness is power. Choose platforms wisely, verify claims independently, and never assume decentralization equals safety.
By integrating proven security practices and fostering greater transparency, the DEX community can build a future that’s not only decentralized but truly trustworthy.
