Orbit Chain's bridge reportedly hacked for $81.5 million

Quick Take

  • Orbit Chain’s cross-chain bridge has reportedly been hacked for $81.5 million in cryptocurrencies and stablecoins. 
  • The exact nature of the hack is unknown.

Orbit Bridge, a cross-chain bridge protocol, has seen unusual outflows of $81.5 million in several cryptocurrencies in what appears to be a major hack.

In five separate transactions, each to a fresh wallet, the Orbit Bridge sent $50 million in stablecoins (30 million Tether, 10 million DAI, and 10 million USDC), 231 wBTC (about $10 million), and 9,500 eth (about $21.5 million). The hack was first noticed by X user Kgjr

The bridge appears to have close ties to the Klaytn KLAY +6.01% ecosystem; Klaytn's explorer shows that 9 of the top 10 tokens on the network by circulating market cap are Orbit Bridge wrapped assets.
