IoTeX is offering a 10% bounty to recover approximately $4.4 million in stolen funds from cross-chain bridges.

PANews reported on February 24th that, according to CoinDesk, the IoTeX public blockchain project's cross-chain bridge ioTube suffered a loss of approximately $4.4 million on February 21st due to a compromised Ethereum-side validator owner's private key . IoTeX sent an on-chain message to the attackers, promising a white-hat bounty of approximately 10% (about $440,000) for returning the funds within 48 hours, without pursuing legal action or providing their identity information to law enforcement. The project team stated that they have fully tracked the flow of funds, flagged and frozen the relevant exchange deposit addresses, identified four Bitcoin addresses holding approximately 66.6 BTC, and will introduce a malicious address blacklist through the mainnet v2.3.4 upgrade.
