Concerns about a potential exploit were first raised by pseudonymous Twitter user Kgjr on December 31, who highlighted significant outflows from the Orbit Chain Bridge protocol.

Blockchain analytics platform Arkham Intelligence revealed that the hackers orchestrated five separate transactions, transferring $30 million in Tether (USDT), $10 million in USD Coin (USDC), Ethereum (ETH), 231 Wrapped Bitcoin (WBTC), and $10 million worth of the algorithmic stablecoin DAI to fresh wallets.

Orbit Chain Facilitates Cross-Chain Transfers Between Decentralized Networks

Orbit Chain, a South Korean-based multi-asset blockchain, is renowned for facilitating cross-chain transfers between various decentralized networks, particularly EVM-compatible networks and Klaytn. Notably, the protocol has strong ties to the Klaytn network, with eight of the largest assets on Klaytn being wrapped assets on the Orbit Bridge.

The native coin of Orbit Chain (ORC) dropped as much as 19% upon the news of the exploit. At the time of writing, the coin is trading at $0.0576, with the price continuing to fall, as per Coingecko data.
