Fogo Blockchain Halts Mainnet After $3M Token Exploit Exposes Smart Contract Flaws
Layer 1 blockchain Fogo suspended its mainnet on August 28, 2026, after an attacker siphoned 400 million FOGO tokens—10% of supply and valued at $3 million—by exploiting a vulnerability in its smart contract code. The breach eroded user trust and drew attention to risks like unchecked contract permissions and insufficient code audits. Competing chains and token issuers now face increased regulatory and user scrutiny, with comprehensive security reviews and insurance coverage becoming standard expectations.
