Polkadot Hit by Cross-Chain Exploit as 1B DOT Minted on Ethereum
Share:
Cross-chain exploit: attacker forged Hyperbridge messages to gain admin control and minted 1,000,000,000 DOT on Ethereum (Polkadot token), exposing a major cross-chain security vulnerability. - Large-scale dump and proceeds: the entire minted supply was swapped in one transaction for 108.2 ETH (~$237K); mint size was ~2,800x the reported contract supply (~356,000 DOT) and funds routed through DeFi liquidity pools to an EOA. - Market and protocol risk: incident highlights acute cross-chain/bridge security risk for Polkadot/DOT, immediate token dilution and potential market impact, and raises concerns for DeFi bridges and security audits.

- Attacker minted 1B DOT and dumped the entire supply for 108.2 ETH ($237K).
- The exploit used forged cross-chain messages via Hyperbridge to gain admin control.
- Mint size reached 2,800x the reported supply of the affected contract.
Polkadot (DOT) has been hit by a cross-chain exploit after an attacker minted 1 billion DOT tokens on Ethereum. The entire supply was dumped in a single transaction, generating 108.2 ETH, roughly $237,000.
On-chain data shows the attacker moved fast. The tokens were minted and swapped immediately, leaving no time for intervention. The scale of the mint was extreme, exceeding 2,800 times the reported circulating supply of approximately 356,000 DOT on the affected contract.
The funds were routed to an externally owned wallet after passing through decentralized liquidity pools.
