Balance Coin price plunges 99% due to 42DAO vulnerability
Balance Coin (BLC), an algorithmic stablecoin designed to maintain a one-to-one peg with the US dollar, has plummeted more than 99% following a security vulnerability attack on its decentralized autonomous organization 42DAO. Blockchain security firm PeckShield confirmed the incident, which caused the token to lose its dollar anchor and its market value to close to zero.
vulnerability event passes through
According to CoinMarketCap data, BLC is trading at approximately $0.001412 as of press time, down 99.85% in the past 24 hours. The crash followed an attack on 42DAO, which PeckShield reported on social media platform X as a $915,000 security breach. Specific details of the attack are still under investigation, but preliminary reports suggest that a vulnerability in the protocol smart contract allowed attackers to withdraw funds, triggering a catastrophic loss of confidence in the underlying mechanism of the stablecoin.
Limited impact on broader markets
Despite the severity of the crash, the broader cryptocurrency market does not appear to have been greatly affected. Before unanchoring, BLC had a market value of approximately $3.51 million, a relatively small figure compared to major stablecoins such as USDT or USDC, which have market capitalizations of tens of billions of dollars. Analysts pointed out that the incident is unlikely to trigger systemic contagion, but it is another stark reminder of the risks inherent in the algorithmic stablecoin model.
What does this mean for stablecoin investors
Rather than holding fiat collateral, algorithmic stablecoins rely on complex mechanisms-often involving arbitrage and seigniorage-to maintain their anchor. The collapse of TerraUSD (UST) in 2022 erased more than $40 billion in value, demonstrating the fragility of such design models. The BLC incident further shows that even smaller algorithmic stablecoins are extremely vulnerable to sudden loss of confidence when faced with security breaches. For investors, the incident highlights the importance of due diligence on the security of agreements and the risks inherent in unsecured stable assets.
Conclusion
Balance Coin plunged 99% after the 42DAO attack, adding another warning page to algorithmic stablecoins. While BLC's limited market value curbed the scope of damage, the incident revealed persistent vulnerabilities in the DeFi protocol and the fragile trust that underpins algorithm anchoring. As the investigation continues, the incident is likely to trigger further regulatory review of similar projects and deepen investor skepticism.
FAQs
Question 1: Why did Balance Coin lose its anchor in the US dollar?
Answer: Balance Coin lost its anchor after the 42DAO suffered a security breach, and the attacker withdrew approximately $915,000 from the agreement. The invasion triggered a loss of confidence in the stablecoin algorithm mechanism, causing prices to plummet 99%.
Question 2: Will this crash pose a risk to the broader cryptocurrency market?
Answer: The impact on the broader market is expected to be limited. BLC's market value before unanchoring was only about US$3.5 million, which is small compared to major stablecoins and is therefore unlikely to trigger systemic contagion.
Question 3: What is an algorithmic stablecoin? Why are they more risky?
Answer: Algorithm stablecoins rely on software algorithms and market incentives-and illegal currency reserves-to maintain price stability. They are considered risky assets because they rely on continued market confidence and arbitrage behavior; once this confidence is broken, the anchoring mechanism can quickly collapse, as demonstrated by 2022 's TerraUSD and now Balance Coin.
