Polkadot price crashes 5% after $20M wiped in Hyperbridge exploit minting 1B fake DOT on Ethereum.

Polkadot ($DOT) suffered a sudden 5% price drop, losing $20 million in market cap due to an exploit in Hyperbridge, a third-party bridge connecting Polkadot to Ethereum. The attacker minted 1 billion fake wrapped DOT tokens on Ethereum and sold them on Uniswap, causing major price slippage and liquidations of $728,000 in DOT longs. The core Polkadot network remains secure, as the vulnerability was in Hyperbridge's architecture, specifically its zero-day exploit and lack of a dispute window. Investors should verify holdings and monitor updates as the market reacts to this incident.
