Recently, the hacking incident involving Rhea Finance has garnered significant attention. This lending protocol on the NEAR ecosystem suffered a serious security vulnerability in its margin trading feature, resulting in a loss of $18.4 million, which is quite substantial.

The attack method was actually quite cunning. The hacker exploited a flaw in the transaction routing by forging token pools to manipulate the flow of lending tokens, leading to a large number of positions lacking collateral, ultimately triggering a chain liquidation. This also highlights that there are still many weak points in DeFi security, especially details like slippage protection mechanisms that are easily overlooked.

Rhea Finance's official statement later said they would use existing resources to compensate affected users' losses, showing a relatively proactive attitude. However, market reactions indicate that the RHEA token's price has been impacted, currently fluctuating around $0.01, with a 24-hour change of +0.71%. The incident has further intensified concerns about the security of DeFi protocols.

Such events remind us that when choosing trading platforms and participating in DeFi projects, security audits and risk management must not be taken lightly. Although Rhea Finance's misfortune is unfortunate, it also encourages the entire ecosystem to pay more attention to these issues.
