How scoring works →Summary
KiloEx is a decentralized perpetual futures exchange (DEX) backed by YZi Labs (formerly Binance Labs), deployed across opBNB, Base, BNB Chain, Taiko, and other networks. In April 2025, the platform suffered a $7.5–8.44 million oracle price manipulation exploit caused by an access control vulnerability in its TrustedForwarder contract; the attacker subsequently returned all stolen funds within 3.5 days after accepting a $750,000 white-hat bounty. The platform relaunched on April 24, 2025 after a partial security audit, with a full comprehensive audit still pending at that time.
