10 Billion DOT Dump Sees Only $237,000 Cashout, Hyperbridge Cross-Chain Gateway Hit by Fake News Attack

BlockBeats News: On April 13, according to CertiK monitoring, the Hyperbridge cross-chain gateway contract on the Ethereum chain suffered a vulnerability exploit. The attacker manipulated the Polkadot token contract's admin permission by forging messages, proceeded to mint 10 billion DOT tokens, and dumped them all, ultimately realizing a modest profit of only about $237,000.

The profit was significantly lower than the minted amount due to extremely limited on-chain liquidity—intense selling pressure instantly crashed the price from $1.22 to nearly zero, rendering most of the minted tokens nearly illiquid.

The attack targeted the bridged version of DOT assets on Ethereum, not the Polkadot native chain itself. Currently, neither Hyperbridge nor Polkadot's official team has released a formal response.
