SVM Layer-1 network Fogo has temporarily halted mainnet operations after detecting unauthorized activity, taking preventive steps to stop further transfers of affected assets. About 400 million FOGO tokens were earlier moved from Fogo Foundation wallets to an attacker-controlled address, a breach the foundation said prompted immediate notices to trading platforms and contact with law enforcement and forensic experts. During the pause, Fogo said it will upgrade the network and restrict addresses tied to the incident, then share further updates once more information is confirmed, urging users to rely only on official channels. The foundation previously reported the roughly 400 million FOGO theft as representing about 4% of a 10 billion total supply and valued near $3 to $3.88 million after an 18-20% price drop around $0.0075, while stating the chain itself was unaffected and user funds were not hit; exchanges including Bitget and MEXC were alerted. Cause of the breach, fuller affected-asset scale, and a mainnet recovery timeline have not yet been published. The high-performance Solana Virtual Machine chain, developed by Douro Labs and launched in January 2026 after raising $13.5 million including a Binance token sale, faces renewed scrutiny over foundation-level control during the halt.
