Fogo’s mainnet has stopped producing blocks for about 46 hours since Saturday afternoon after the Fogo Foundation was attacked and 4 million FOGO tokens were moved to an attacker address, according to ChainCatcher. The stolen amount represents about 10.3% of circulating supply.
The foundation first said the chain itself was not affected. Fifteen hours later, the network was deliberately paused, and the team said it planned to restrict the related addresses through an upgrade.
Fogo’s official explorer currently shows block 718,525,971 as the last block. Its RPC endpoint is returning a 502 error. DefiLlama’s tracking also shows the chain’s total value locked frozen at $987,000 for three consecutive days.
The shutdown was made possible by Fogo’s validator structure. The chain is governed by a council of seven voting validators, and the foundation’s stake is evenly split across seven operators. That setup allows coordination within minutes to pause the network and apply a client-level blacklist to addresses.
On the exchange side, KuCoin and Gate have both disabled FOGO deposits and withdrawals while keeping trading available. Spot volume over the past 24 hours was about $2.3 million.
At the same time, a fake X account impersonating the Fogo Foundation, @FcgoFNDN, posted a false compensation voting link. Fogo said users should rely only on information released through official channels.
Fogo is the second network to undergo a deliberate shutdown over the weekend. Earlier, Cronos rolled back state after an attack involving the Tectonic lending protocol.
Before launching its mainnet in January, Fogo had sold 2% of supply through Binance, raising about $7 million at a $350 million valuation.
So far, the foundation has not disclosed details of the attack, any compensation arrangement, or a timetable for restarting the network.
