Reports Claim Polkadot Bridge Vulnerability Was Exploited to Mint 1 Billion DOT

Additional reporting says the attacker swapped the illicitly minted bridged DOT for 108.2 ETH worth about $237,000, while separate market and policy updates added broader crypto context.

Fact Check
The specific core claim is supported by two fetched reports: PANews article '派盾:10亿枚DOT在以太坊上被铸造并抛售 | PANews' says 1 billion DOT were minted and sold on Ethereum, and 'Hyperbridge网关遭合约攻击,黑客通过铸造并出售10亿枚DOT获利约23.7万美元 | PANews' attributes the incident to fake messages that changed admin rights for a Polkadot token contract on Ethereum. That second source aligns closely with the user's wording about CertiK Alert and indicates the exploit affected an Ethereum-side token/bridge contract, not the native Polkadot chain itself. The Odaily link traced to a PeckShieldAlert X post, which further supports that this was not just one outlet repeating another, though the X post could not be directly fetched here. I found no fetched authoritative source in this run contradicting the claim. Confidence is medium because direct access to the primary X posts and an official Polkadot/Hyperbridge confirmation were unavailable in the tool results.

Summary

The Hyperbridge exploit remains centered on reports that a vulnerability in the bridge’s Ethereum gateway let an attacker mint 1 billion unauthorized bridged DOT. The latest update says the attacker swapped the minted tokens for 108.2 ETH, worth about $237,000, broadly aligning with earlier loss estimates near $240,000. The new content also notes broader market moves, with BTC up 4.43%, ETH up 7.34%, and AAVE rising 10.05%, and says Korea’s central bank proposed crypto circuit breakers after Bithumb’s mistaken transfer of 620,000 BTC.

Terms & Concepts
  • DOT: The native cryptocurrency of the Polkadot network, used for staking, governance, and other network functions.
  • Ethereum: A blockchain network for smart contracts and decentralized applications; Hyperbridge’s affected gateway contract operated on Ethereum.
  • BTC: The ticker symbol for Bitcoin, the largest cryptocurrency by market capitalization.
