Sonne Finance loses $20 million in DeFi hack
Sonne Finance suffered a devastating exploit that resulted in a loss of at least $20 million
Decentralized finance (DeFi) has revolutionized the financial landscape, providing unprecedented levels of accessibility, transparency and efficiency. However, this booming sector has also become a prime target for sophisticated cyberattacks. The latest victim in a series of high-profile DeFi hacks is Sonne Finance, a decentralized lending protocol running on the Optimism and Base networks. The protocol suffered a devastating exploit that resulted in a loss of at least $20 million. This incident sent shockwaves through the DeFi community, highlighting persistent vulnerabilities and the crucial need for robust security measures.
Hack Overview
On May 12, 2024, Sonne Finance was hacked, resulting in a significant loss of funds. The protocol, which is a fork of Compound Finance, has become the latest target of a well-known vulnerability that has plagued other DeFi projects. In response, Sonne Finance immediately closed all markets on the Optimism platform to contain the damage and confirmed that funds on the Base network were secure.
Exploit Details
PeckShield, a leading blockchain security company, provided a detailed analysis of the attack. According to their investigation, the hacker exploited a vulnerability inherent to Compound Finance forks. This flaw allowed the attacker to manipulate smart contracts on the Optimism network, ultimately siphoning approximately $20 million from Sonne Finance.
Understanding the operating technique
Sonne Finance, as a derivative of Compound V2, inherited some weaknesses in its codebase. These vulnerabilities have been exploited in previous attacks on other DeFi platforms, such as Hundred Finance and Midas Capital. The common technique is to manipulate exchange rates to artificially inflate the value of collateral, allowing attackers to drain loan pools with minimal tokens.
Sonne Finance’s feat was aided by the introduction of a new market contract for VELO and a subsequent governance proposal to enable it. Once the proposal was adopted, the attacker timed his action precisely, executing the contract immediately after the 24-hour deadline expired. This allowed them to be the first to exploit the vulnerability.
Response and recovery efforts
Immediately after the hack, Sonne Finance took decisive action to prevent further damage. The protocol shut down all markets on the Optimism platform, ensuring that funds on the Base network remained unaffected. This rapid response was crucial to containing the exploit and protecting remaining assets.
In its postmortem analysis, Sonne Finance identified wallet addresses associated with the attacker and initiated efforts to recover the stolen funds. They offered a bug bounty to encourage the return of assets and appealed to the broader crypto community for support. The team also collaborated with relevant stakeholders to strengthen their recovery efforts and improve future security measures.
Implications for DeFi Security
The Sonne Finance hack highlights a critical issue within the DeFi ecosystem: the security of protocols built on legacy codebases. Compound V2, which has been extensively forked, has recurring vulnerabilities that have been exploited repeatedly. As DeFi continues to grow, the importance of rigorous security protocols, including regular audits and rapid patching of vulnerabilities, cannot be overstated.
Lessons learned and way forward
The Sonne Finance hack offers several important lessons for the DeFi community:
Rigorous code audits: Regular and comprehensive audits of smart contracts are essential. Security companies must continually review code to identify and fix vulnerabilities before they can be exploited.
Timelock governance and security: Timelock governance mechanisms and implementations should be reviewed and strengthened. Protocols must ensure that governance proposals do not inadvertently introduce vulnerabilities.
Community Vigilance: The broader DeFi community must remain vigilant and proactive. Collaboration between projects, security companies and users can lead to faster identification of threats and more effective responses.
Enhanced Incident Response: DeFi protocols must have robust incident response plans. This includes clear procedures for shutting down operations, communicating with stakeholders, and initiating recovery efforts.
Education and Awareness: Increased awareness of common vulnerabilities and exploitation techniques can help developers and users understand risks and take preventive measures.
The Sonne Finance hack is a stark reminder of the vulnerabilities that persist in the DeFi space. As the industry continues to innovate and push the boundaries of traditional finance, security remains a primary concern. The incident highlights the need for continued vigilance, rigorous security practices and a collaborative approach to safeguard the future of decentralized finance.
As Sonne Finance works to recover from this setback, the DeFi community must heed the lessons learned. By prioritizing security, improving governance mechanisms, and fostering a culture of continuous improvement, the industry can build a more resilient and secure decentralized financial system.

Ethena downplays danger of letting traders use USDe to back risky bets – DL News
- Ethena and ByBit will allow derivatives traders to use USDe as collateral.
- There is a risk in letting traders use an asset partially backed by derivatives to place more bets.
Ethena has downplayed the dangers of a new feature, which will allow traders to put up its synthetic dollar USDe as collateral when trading derivatives, which are risky bets on the prices of crypto assets.
While allowing users to underwrite their trades with yield-bearing USDe is an attractive prospect, Ethena said there is potential risk in letting traders use an asset partially backed by derivatives to place even more derivatives bets.
“We have taken this risk into account and that is why Ethena operates across more than five different sites,” said Conor Ryder, head of research at Ethena Labs. DL News.
The move comes as competition in the stablecoin sector intensifies.
In recent weeks, PayPal grown up the amount of its stablecoin PYUSD in circulation 96%, while the MakerDAO cooperative plans a rebrandingaiming to increase the supply of its DAI stablecoin to 100 billion.
US dollar growth stagnates
It comes as Ethena has lost momentum after its blockbuster launch in December.
In early July, USDe reached a record level of 3.6 billion in circulation.
That figure has now fallen by 11% to around 3.2 billion.

New uses for USDe could boost demand for Ethena’s products.
This is where the new plan, announcement Tuesday with ByBit, one of its partner exchanges, is coming.
Ethena users create USDe by depositing Bitcoin or Ether into the protocol.
Ethena then covers these deposits with short positions – bearish bets – on the corresponding asset.
This creates a stable support for USDe, unaffected by price fluctuations in Bitcoin or Ether.
Mitigate risks
While using USDe as collateral for derivatives trading is proving popular, it is unclear what the effects will be if the cryptocurrency market experiences major fluctuations.
Using derivatives as collateral to place more bets has already had disastrous effects.
In June 2022, Lido’s liquid staking token stETH broke its peg to Ether following the fallout from the Terra collapse.
Many traders who used looping leverage to increase their stETH staking yields were liquidated, creating a cascade that caused the price of Ether to drop by more than 43%.
Ethena Labs founder Guy Young said: DL News His office and his partners have taken many precautions.
Ethena spreads bearish bets supporting the USDe across the five exchanges it partners with.
According to Ethena, 48% of short positions supporting USDe are on Binance, 23% on ByBit, 20% on OKX, 5% on Deribit, and 1% on Bitget. website.
In doing so, Ethena aims to minimize the impact of an unforeseen event on a stock market.
The same theory applies to the distribution of risks across different supporting assets.
Fifty percent of USDe is backed by Bitcoin, 30% by Ether, 11% by Ether liquid staking tokens, and 8% by Tether’s USDT stablecoin.
Previous reviews
Ethena has already been criticised regarding the risks associated with USDe.
Some have compared USDe to TerraUSD, an undercollateralized stablecoin that collapsed in 2022.
“It’s not a good design for long-term stability,” said Austin Campbell, an assistant professor at Columbia Business School. said as the USDe launch approaches.
Young replied to critics, saying the industry needs to be more diligent and careful when “marketing products to users who might not understand them as well as we do.”
Ethena has since added a disclaimer on its website stating that USDe is not the same as a fiat stablecoin like USDC or USDT.
“This means that the risks involved are inherently different,” the project says on its website.

Cryptocurrency and defi firms lost $266 million to hackers in July
In July 2024, the cryptocurrency industry suffered a series of devastating attacks, resulting in losses amounting to approximately $266 million.
Blockchain Research Firm Peck Shield revealed in an X post On August 1, attacks on decentralized protocols in July reached $266 million, a 51% increase from $176 million reported in June.
The most significant breach last month involved WazirX, one of India’s largest cryptocurrency exchanges, which lost $230 million in what appears to be a highly sophisticated attack by North Korean hackers. The attack was a major blow to the stock market, leading to a break in withdrawals. Subsequently, WazirX launched a program in order to recover the funds.
Another notable incident involved Compound Finance, a decentralized lending protocol, which suffered a governance attack by a group known as the “Golden Boys,” who passed a proposal who allocated 499,000 COMP tokens – valued at $24 million – to a vault under their control.
The cross-chain liquidity aggregation protocol LI.FI also fell victim On July 16, a hack resulted in losses of $9.73 million. Additionally, Bittensor, a decentralized machine learning network, was one of the first protocols to suffer an exploit last month, loming $8 million on July 3 due to an attack targeting its staking mechanism.
Meanwhile, Rho Markets, a lending protocol, suffered a $7.6 million breach. However, in an interesting twist, the exploiters research to return the stolen funds, claiming the incident was not a hack.
July 31, reports The Terra blockchain protocol was also hacked, resulting in a loss of $6.8 million across multiple cryptocurrencies. As crypto.news reported, the attack exploited a reentrancy vulnerability that had been identified a few months ago.
Dough Finance, a liquidity protocol, lost $1.8 million in Ethereum (ETH) and USD Coin (USDC) to a flash loan attack on July 12. Similarly, Minterest, a lending and borrowing protocol, saw a loss of $1.4 million due to exchange rate manipulation in one of its markets.
Decentralized staking platform MonoSwap also reported a loss of $1.3 million following an attack that allowed the perpetrators to withdraw the liquidity staked on the protocol. Finally, Delta Prime, another decentralized finance platform, suffered a $1 million breach, although $900,000 of the stolen funds was later recovered.

What is DeFi?
Decentralized finance (DeFi) represents a paradigm shift in financial services, offering internet-based financial products such as trading, lending, and borrowing through the use of decentralized public blockchains.
By implementing blockchains, smart contracts, and digital assets, DeFi protocols provide financial services through a decentralized ecosystem, where participants do not have to deal with intermediaries when transacting.
What is Bitcoin DeFi?
The inherent limitations of the Bitcoin mainchain in supporting the intricacies of decentralized finance have created the need to develop smart contract-based Layer 2 solutions.
Additionally, the advent of the Ordinals protocol in 2023, which facilitated the emergence of fungible token standards such as BRC-20 and Runes, catalyzed the growth of DeFi on the Bitcoin blockchain.
This expansion in protocol diversity has broadened the applications of the world’s leading cryptocurrency network beyond the core base-layer use cases around value preservation and transactional capabilities.
Therefore, Bitcoin DeFi has become a nascent sector within the digital asset market, after previously being a missing essential part of the Bitcoin ecosystem.
Bitcoin DeFi in its early days
Integrating decentralized finance (DeFi) concepts into the Bitcoin ecosystem has been a journey of innovation and perseverance. Early attempts to bridge the gap between Bitcoin’s fundamental simplicity and DeFi’s complexities have spawned pioneering projects that, while laying essential foundations, have also encountered significant obstacles.
Colored coins
Colored coins represented an early foray into tokenizing real-world assets on the Bitcoin blockchain. By leveraging the existing network to track ownership of assets ranging from stocks to real estate, this approach highlighted Bitcoin’s potential as a platform beyond digital currency. However, scalability and practical implementation challenges have limited its widespread adoption.
Counterpart
Building on the colored coins, Counterparty has become a platform for creating and trading digital assets, including non-fungible tokens (NFTs), on Bitcoin.
The introduction of popular projects like Rare Pepe NFTs has demonstrated the growing appeal of digital collectibles. However, constraints around user experience and network efficiency have hampered its full potential.
These early experiments, while not fully realizing their ambitions, served as valuable stepping stones, informing Bitcoin DeFi’s subsequent developments. Their challenges highlighted the need for more sophisticated infrastructure and protocols to harness the full potential of decentralized finance on the Bitcoin network.
Bitcoin DeFi Today
Today, building DeFi applications on Bitcoin is primarily done in the realm of Layer 2 (L2) networks. This architectural choice is motivated by the limitations of Bitcoin’s base layer in supporting complex programmable smart contracts.
Bitcoin’s original design prioritized security and decentralization over programmability, making it difficult to develop sophisticated DeFi protocols directly on its blockchain. However, the recent emergence of protocols like Ordinals, BRC-20, and Runes, while not DeFi in their own right, has sparked possibilities for future DeFi-like applications on the main chain.
In contrast, L2 solutions offer a scalable and programmable environment built on Bitcoin, enabling the creation of various DeFi products.
By expanding Bitcoin’s capabilities without compromising its core principles, L2s have become the preferred platform for developers looking to build DeFi applications that encompass trading, lending, staking, and more.
Leading L2 networks such as Lightning Network, Rootstock, Stacks, and Build on Bitcoin provide the infrastructure for these efforts. Some of these L2s have even introduced their own native tokens to the network, further expanding Bitcoin’s DeFi ecosystem.
Essentially, while Bitcoin’s core layer presents challenges for DeFi development, its security and decentralization have provided a foundational layer for the innovative L2 landscape to thrive.
Bitcoin Layer 2 offers a promising path to building a robust and thriving Bitcoin-based DeFi ecosystem that offers trading, staking, lending, and borrowing. All you need is a DeFi Wallet like Xverse to access the new world of decentralized financial services secured by Bitcoin.
Conclusion
The integration of DeFi principles into the Bitcoin ecosystem, primarily facilitated by Layer 2 solutions, marks a significant evolution in the digital asset landscape.
Building on the foundational work of pioneers like Colored Coins and Counterparty, the industry has evolved into more sophisticated platforms like Rootstock, Stacks, and Build on Bitcoin to create a thriving Bitcoin-powered DeFi ecosystem.
