Attacker Mints $1 Billion Polkadot Tokens on Ethereum, Steals $250,000

On April 13, 2026, a significant security breach occurred involving Polkadot's bridged DOT token on Ethereum. An attacker exploited a vulnerability by sending a forged cross-chain message, bypassing the bridge contract's state proof validation. This allowed the attacker to assume admin control over the bridged DOT token and mint the entire supply, which was then sold for approximately $237,000. (source) This incident highlights persistent risks in cross-chain interoperability, particularly concerning bridge contract security. For the coin market, such events can erode investor confidence in both the specific token and the broader ecosystem, potentially leading to short-term price volatility. It underscores the importance of rigorous security audits and may prompt a reassessment of bridge usage and design across the industry.
