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

On April 13, 2026, a critical security breach occurred when an attacker exploited a vulnerability in a Polkadot-Ethereum bridge contract. By forging a cross-chain message and bypassing state proof validation, the attacker gained admin control over the bridged DOT token contract on Ethereum. This enabled them to mint the entire supply of DOT tokens, which they subsequently sold for approximately $237,000. (source) This incident highlights ongoing risks associated with cross-chain bridges and smart contract security. For the coin market, such exploits can undermine user confidence, potentially increasing volatility and reducing institutional interest in Polkadot and similar interoperable projects. While the direct monetary loss was limited, the reputational damage could have longer-term effects on DOT's price and adoption.
