If you've been dabbling in the wild world of decentralized finance (DeFi) or are just curious about what the fuss is all about, then buckle up because this one's for you. In a recent talk, Paul Len, a long-time DeFi participant, shared his stream of consciousness on risk in DeFi. With nearly five years of hands-on experience in yield farming, airdrop hunting, and liquidity provision, he laid out some hard-learned lessons that can help anyone trying to navigate this space.
The Early DeFi Days: Degenerate Investing
Paul started out like many of us—throwing money at random projects, reading a few minutes about them, and seeing what stuck. Back in 2020, when the pandemic shut down his business, he stumbled into crypto and got sucked into the allure of speculative investments. Sometimes it worked out, sometimes it didn’t. It was a game of trial and error—classic DeFi degen behavior.
Understanding the Dangers in Crypto
Paul listed ten major risks in crypto, but let’s highlight a few that stand out:
1. Private Key Management
If you lose your seed phrase or it gets compromised, your funds are gone—simple as that. Unlike banks, no one can recover your account for you.
2. Web2 Phishing Attacks
One of the most common ways people lose their money is by falling for fake websites that mimic real ones. Even experienced security professionals have fallen for them after a few drinks late at night.
3. 51% Attacks
In proof-of-work blockchains, if someone controls 51% of the network, they can manipulate transactions—though this is rare in major chains like Bitcoin.
4. Infrastructure Bugs and Exploits
Smart contracts, bridges, and multisigs are all potential attack vectors. Some of the biggest hacks in DeFi history have come from bridge exploits.
The DeFi Risk Pyramid: Understanding Where You Stand
Paul broke down risk into a pyramid. At the top, you have the safest asset—Bitcoin held in self-custody. Below that, risks increase as you move into different layers:
Bitcoin on Self-Custody – The gold standard for security.
Ethereum & Other L1s – Still secure, but with more network risks.
Smart Contracts (Aave, Maker, Uniswap, Lido) – These are heavily audited, but still introduce risk.
Bridged Assets & L2s – Moving assets across chains introduces another layer of smart contract risk.
Multisigs and Governance Risks – If a multisig is compromised, so is the entire protocol.
If You Don’t Understand the Yield, You Are the Yield
One of the biggest lessons Paul emphasized is that if you're getting high yield in DeFi and you don't know why—you're likely the exit liquidity. He shared an example of liquidity pools offering 600% APY, where if the token price stayed the same for two months, you’d double your money. Sounds great, right? But that yield is coming from somewhere, and if you don’t know where, you might be the one paying for it in the long run.
Uniswap V3: Not as Simple as It Looks
Providing liquidity isn’t just about earning fees—it’s about managing risk. Paul explained how V3 is essentially V2 but with leverage, making it even riskier. If you’re not careful, you could end up losing money due to impermanent loss, where your assets get rebalanced unfavorably due to price movement.
Smart Contract Audits: Not a Guarantee of Safety
Another key takeaway: an audit does not mean a contract is safe. Even the best projects find vulnerabilities after multiple audits. The term “audit” can be misleading because auditors don’t take responsibility for lost funds. They’re simply providing expert insights on security risks.
Airdrops and Market Inefficiencies
For those looking for the next big airdrop, Paul mentioned that Hyper Liquid is expected to release another big one soon. However, he also noted that airdrops are getting harder to predict, and farming them requires strategic planning.
Final Thoughts: Protect Your Neck
Paul wrapped things up with one overarching message: if you're investing in DeFi without understanding the risks, you're just gambling. While gambling can sometimes pay off, long-term success in DeFi comes from identifying inefficiencies, understanding risks, and managing them effectively.
So, whether you're a seasoned yield farmer or just getting started, remember—DeFi is a jungle. Move smart, do your research, and, as Paul put it, protect your neck.
