The Rise and Challenges of the Blockchain Industry


The blockchain industry has been making significant strides in recent years, revolutionizing various sectors by introducing decentralization and enhancing security. However, these advancements have also presented new challenges, as highlighted by a recent attack on the decentralized finance protocol, Zunami Protocol, which resulted in a substantial financial loss.

The Zunami Protocol Attack

Zunami Protocol experienced an attack on its “zStables” pool on Curve Finance, leading to the theft of over $2.1 million. This exploit was discovered by the blockchain security firm, PeckShield, who traced the issue back to a price manipulation vulnerability. Another security firm, Ironblocks, corroborated this estimate, emphasizing the severity of the incident.

The exploit was first detected by PeckShield on August 13th at 10:47 UTC, and Zunami Protocol confirmed it approximately 20 minutes later. The vulnerability exploited in this attack involved an incorrect calculation of prices, leading to the manipulation of the system. Consequently, the attacker managed to siphon a considerable sum from the Curve Pool.

Zunami Protocol assured its users that their collateral in the Curve pools remained secure and that they were actively investigating the issue. Despite this attempt to reassure the community, the incident highlights the vulnerability of even decentralized systems and the need for constant vigilance to mitigate such attacks.

Flash Loan Price Manipulation Attack

The nature of the attack that impacted Zunami Protocol’s zETH and UZD suggests a flash loan price manipulation technique. Flash loans are a unique feature of blockchain platforms, allowing users to borrow and repay funds within a single transaction. The manipulative technique employed by the attacker involves obtaining a flash loan, influencing the price calculation algorithm, and executing transactions to their advantage.

This incident serves as a reminder of the evolving sophistication of attacks in the blockchain industry. Despite its promise of security and transparency, blockchain technology attracts the attention of hackers seeking to exploit vulnerabilities. As the industry matures, it is crucial for developers and protocol users to remain informed about the latest attack vectors and to implement robust security measures.

Zunami Protocol and Decentralized Revenue Aggregation

Zunami Protocol is a decentralized revenue aggregator that enables users to stake stablecoins for yield. Its largest stablecoin pools are hosted on Curve Finance, which offers low slippage and optimized trading for stablecoins. Through its protocol, users can earn passive income by participating in liquidity provision and yield farming.

The incident involving Zunami Protocol highlights the potential risks associated with decentralized finance (DeFi) platforms. Despite the security measures in place, vulnerabilities can be exploited, leading to substantial financial losses. It serves as a crucial lesson for both protocol developers and users to remain vigilant and continuously improve security measures to mitigate potential attacks.


The blockchain industry has witnessed remarkable growth, empowering various sectors with decentralization and enhanced security. However, recent incidents such as the attack on Zunami Protocol’s Curve pool remind us of the challenges faced by this evolving industry. Despite the robustness of blockchain technology, constant vigilance and security improvements are necessary to thwart sophisticated attacks.

As the industry matures, it is crucial for developers, security firms, and users to collaborate in identifying vulnerabilities and implementing robust security mechanisms. Only through collective efforts can the blockchain industry ensure the integrity and trustworthiness of decentralized systems, thus fulfilling its transformative potential.
