Attacker Mints $1 Billion Polkadot Tokens on Ethereum, Steals Just $250,000
CertiK said the attacker used a forged cross-chain message to take admin control and mint 1 billion DOT, then sold them for about $237,000.
- On Sunday, an attacker exploited Hyperbridge's cross-chain gateway, minting 1 billion Polkadot tokens on Ethereum and profiting approximately $237,000 from the sale.
- The vulnerability resided in Hyperbridge's EthereumHost contract validation, which failed to verify cross-chain messages; a forged message allowed the attacker to execute changeAdmin and gain control of the bridged token contract.
- Limited depth in the Uniswap DOT-ETH pool meant 1 billion tokens overwhelmed available liquidity; the attacker routed tokens through Odos Router, extracting roughly 108.2 ETH across multiple swaps.
- CertiK flagged the exploit and confirmed the attack vector was the Hyperbridge gateway; the Polkadot core network and native DOT token remained unaffected by the bridge incident.
- This incident adds to a growing list of bridge vulnerabilities in crypto; last month saw a $270 million Drift Protocol drain on Solana, highlighting why bridges remain the weakest link.

Attacker mints $1 billion Polkadot tokens on Ethereum, steals just $250,000
A forged cross-chain message bypassed state proof validation on the bridge contract, granting admin control over the bridged DOT token and allowing the attacker to mint and dump the entire supply for $237,000.
Decentralized finance (DeFi) remains a risky environment often targeted by hackers in search of loopholes to exploit. A reality that has just struck the Hyperbridge protocol, resulting in the creation of 1 billion tokens DOT, for a profit finally estimated at 237,000 dollars. The article Attack of the Hyperbridge protocol - 1 billion tokens DOT created by the hacker appeared first on Cryptoast.
Crypto Hack: Polkadot Price Crashes 4% Amid Major Exploit on Ethereum
Key Insights: Polkadot’s price dropped by up to 7% within minutes, wiping out $20 million in market cap, after the latest DOT token exploit on Ethereum. The DOT price crash triggered $730,000 in liquidations over the last 24 hours. The issue affected only Hyperbridge on Ethereum, while native Polkadot remained unaffected. DOT, the native cryptocurrency of Polkadot, has dropped 4% over the last 24 hours following a major exploit on Ethereum. Acc…
Hyperbridge, a crypto bridge linked to the Polkadot ecosystem, paused its operation after an attacker exploited a code failure to coin a billion DOT tokens without support in Ethereum. Although the theoretical value of the coup was around $1.2 billion, poor liquidity reduced the real loot to just over $237,000 in Ether. *** The attacker tricked Hyperbridge into creating a billion DOT without depositing equivalent funds. Despite the theoretical v…
