Ethereum smart contract vulnerabilities have significantly impacted its price, as seen in historical exploits like the 2016 DAO hack, which drained $50 million in ETH, leading to a sharp price drop and a hard fork. Recent posts on X highlight ongoing concerns, noting a security breach in the Pectra upgrade that caused empty block mining and pushed ETH prices down to $2,062.41. Such incidents erode investor trust, as attackers exploit flaws like reentrancy and malicious contract upgrades, often resulting in millions in losses. While developers work to address these vulnerabilities, the market reacts swiftly, with prices declining amid heightened risk perception. This underscores the need for robust security measures to stabilize Ethereum's value and maintain confidence in its ecosystem.
