INTRODUCTION

Decentralized finance, or DeFi, is a fast-growing sector of the cryptocurrency industry that aims to provide alternative financial services that are open, transparent, and accessible to anyone with an internet connection and a compatible device. DeFi leverages the power of blockchain technology, smart contracts, and decentralized applications (dApps) to enable users to lend, borrow, trade, invest, and earn interest on their crypto assets without relying on intermediaries or centralized platforms. DeFi offers a variety of innovative products and services that are designed to enhance the efficiency, security, and inclusivity of the financial system. However, DeFi also comes with its own set of risks and challenges that users should be aware of and prepared for. Some of the most common and significant risks of using DeFi are:

- Technical risks: DeFi relies on complex and experimental software that may not be fully tested, audited, or verified. This means that there is a possibility of bugs, errors, glitches, or hacks that could compromise the functionality, security, or integrity of the DeFi protocols and platforms. For example, in 2020, a hacker exploited a vulnerability in the DeFi protocol Harvest Finance and drained $24 million worth of crypto assets from its pools. Another example is the recent glitch in the DeFi platform Compound, which accidentally sent millions of dollars worth of crypto to its users due to a faulty price oracle. Users who interact with DeFi software should be aware of the potential technical risks and take precautions such as reading the code, checking the audits, and using reputable and reliable platforms.

- Asset-based risks: DeFi involves the use of various crypto assets that may have different characteristics, features, and risks. Some of these assets may be volatile, illiquid, or subject to manipulation, which could affect their value and performance. For example, in 2020, a sudden drop in the price of Ethereum caused a massive liquidation of collateralized loans on the DeFi platform Maker, resulting in the loss of $8.3 million worth of crypto assets for some users. Another example is the recent flash crash of the token IRON, which was backed by a stablecoin and a governance token, causing the collapse of the DeFi protocol Iron Finance and the loss of millions of dollars for its users⁴. Users who deal with DeFi assets should be aware of the potential asset-based risks and diversify their portfolio, monitor the market, and use risk management tools such as stop-loss orders and limit orders.

- Procedural risks: DeFi involves the use of various procedures and operations that may have different requirements, conditions, and outcomes. Some of these procedures may be complex, confusing, or misleading, which could lead to user errors, misunderstandings, or disputes. For example, in 2020, a user of the DeFi protocol Balancer lost $500,000 worth of crypto assets due to a misunderstanding of how the platform's liquidity pools worked. Another example is the recent controversy over the DeFi protocol SushiSwap, which was accused of being a scam and a copycat of the DeFi protocol Uniswap, causing a loss of trust and confidence among its users and investors. Users who engage with DeFi procedures should be aware of the potential procedural risks and read the documentation, follow the instructions, and seek clarification if needed.

- Financial risks: DeFi involves the use of various financial instruments and strategies that may have different returns, risks, and rewards. Some of these instruments and strategies may be speculative, risky, or unsustainable, which could result in losses, defaults, or insolvencies. For example, in 2020, a user of the DeFi protocol bZx lost $350,000 worth of crypto assets due to a flash loan attack, which exploited the platform's margin trading feature. Another example is the recent failure of the DeFi protocol YAM, which was an experimental and unaudited project that aimed to create a stablecoin with a governance token, but collapsed due to a bug in its code that made its token supply uncontrollable. Users who participate in DeFi financial activities should be aware of the potential financial risks and do their own research, analysis, and due diligence before investing or trading.

- Regulatory risks: DeFi operates in a largely unregulated and uncertain legal environment, which may pose challenges and threats from various authorities and jurisdictions. Some of these authorities and jurisdictions may have different laws, rules, and regulations that may apply to DeFi activities, products, and services, which could result in restrictions, bans, or penalties. For example, in 2020, the US Securities and Exchange Commission (SEC) filed a lawsuit against the DeFi protocol Unikrn, which offered a token that was deemed to be an unregistered security, resulting in a $6.1 million settlement and the destruction of the token. Another example is the recent warning from the UK Financial Conduct Authority (FCA) that DeFi platforms may require authorization and compliance with the relevant rules and regulations, and that users may not have access to compensation or redress schemes if things go wrong. Users who interact with DeFi should be aware of the potential regulatory risks and follow the applicable laws, rules, and regulations of their respective jurisdictions.

Conclusion:

In conclusion, DeFi is a promising and revolutionary sector of the cryptocurrency industry that offers new and exciting opportunities for users to access and benefit from alternative financial services and products. However, DeFi also comes with its own set of risks and challenges that users should be aware of and prepared for. Users who use DeFi should exercise caution and due diligence, and understand the potential benefits and drawbacks of each DeFi innovation.
