DeFi protocol Sturdy Finance loses $800K

Decentralized finance (DeFi) has been considered as one of the most revolutionary developments in the field of finance in recent times. However, the risks associated with using DeFi protocols have been highlighted yet again. On January 4, 2022, an attacker drained $800K from the DeFi protocol Sturdy Finance. This incident showcases the potential risks and vulnerabilities of DeFi protocols that continue to pose a threat.

What is Sturdy Finance?

Sturdy Finance is a decentralized lending platform that allows borrowing and lending of cryptocurrencies. Users can borrow cryptocurrency by using collateral, and the collateral is held in a smart contract until the loan is paid back. The smart contract eliminates the need for a centralized authority, and the interest rates in these protocols are usually higher than traditional banks.

What Happened?

An attacker who remains anonymous managed to exploit a flaw in the smart contract of the Sturdy Finance protocol. The attacker was able to drain $800,000 worth of Dai stablecoin. The attacker sold the stolen tokens instantly on decentralized exchanges such as Uniswap and SushiSwap. The hacker was able to swap the stolen tokens for Ethereum, which was later used to make multiple transactions on the blockchain.

The nature of the attack and the fact that it was not a hack highlights the risks associated with using DeFi protocols. Smart contract-based protocols are vulnerable to attacks as they cannot withstand the flaws within the smart contracts themselves. The smart contract acts as the backbone of DeFi protocols, and any weakness in the smart contract can lead to such attacks.

What happens next?

As soon as the attack was discovered, the Sturdy Finance team acted quickly and stopped any further withdrawals. The team initiated a snapshot of the protocol’s state before the attack and promised to refund the stolen tokens to the victims. However, the snapshot compensation model raises questions about the equity of the compensation model.

The team has also indicated that the attack was not a result of any bug in the code of the protocol but rather a result of the protocol’s architecture. The team is expected to release a detailed post mortem report to provide more details on the crack.

The incident also highlights the need for better security standards and regulations for DeFi protocols. The lack of regulatory oversight has been a challenge in the DeFi space, and incidents such as these reinforce the need for improved regulations. Regulators are already taking notice of the recent incidents of DeFi hacks and exploits and are working to develop regulations to protect investors.

What Can We Learn from the Incident?

The Sturdy Finance hack serves as a reminder of the risks and vulnerabilities associated with using DeFi protocols. As DeFi protocols grow in popularity, attackers will continue to target these protocols. While the DeFi protocols provide a decentralized and transparent system, they are still in the early stages of development.

The incident also highlights the need for better security standards and regulations for DeFi protocols. Security standards must be improved to prevent such attacks and provide security for users’ assets. The regulatory oversight of DeFi protocols is an essential step towards ensuring that users’ interests are protected.

Secondly, it is essential to carry out due diligence before investing in any DeFi protocol. Investors need to understand the risks associated with using these protocols and only invest what they can afford to lose. Investors should also assess the code of the protocol and get an expert opinion to ensure that the protocol is safe.

Finally, the incident shows a need for better auditing practices for DeFi protocols that eliminate vulnerabilities and ensure the overall security of the code. Auditing by professionals can provide additional assurances of the quality of the code, thereby preventing attacks of such nature.

Conclusion:

In conclusion, the incident involving Sturdy Finance demonstrates the potential risks and vulnerabilities of DeFi protocols. Although the promise of decentralization, transparency, and high-interest rates remains a significant attraction for investors, the risks associated with DeFi protocols are also immense. The concept of DeFi is still evolving, and the incident underscores the need for increased regulation and improved security standards. The incident serves as a wake-up call for the DeFi community to improve audit practices, encourage transparency, and tighten security measures to safeguard investors’ interests. Overall, the DeFi sector must learn from this incident and take action to address the ongoing challenges to build a secure and trustworthy platform for users.
