On August 29, 2026, Layer 1 blockchain Fogo suspended its mainnet after attackers obtained 400 million FOGO tokens. The stolen tokens accounted for about 10% of the circulating supply, valued at approximately $3 million at the time of the incident. The mainnet suspension, which halts the production of new blocks, is an emergency measure in response to a severe security incident and will directly impact on-chain users, validators, and DeFi applications.
