A large-scale incident on the L1 blockchain Fogo forced the team to urgently halt mainnet operations. On August 29, an unknown individual managed to obtain 400 million FOGO tokens, accounting for more than 10% of the asset's current circulating supply. This event dealt a serious blow to trust in the project, which had positioned itself as a high-speed platform for on-chain trading.
Incident details and team response
The network halt was initiated as a preventive measure to block further movement of compromised assets. The project's official statement emphasizes that an update will be carried out during the suspension, aimed at restricting addresses associated with unauthorized activity. At the same time, the team has not yet disclosed either the exact timeline for restart or the mechanisms for implementing these restrictions.
Notably, approximately 15 hours before the halt, the Fogo Foundation had already reported the compromise of the organization, claiming that 400 million FOGO had moved to a "dishonest party." At that time, the foundation insisted that blockchain operations were not disrupted, but subsequent events refuted these assurances.
Scale of losses and exchange response
The affected volume of tokens is equivalent to 4% of the genesis supply of 10 billion coins. At the time of the attack, FOGO was trading at around $0.0075, valuing the stolen package at approximately $3 million. The reaction of major trading platforms also served as an alarm signal: Bitget suspended FOGO deposits and withdrawals even before the project's official announcement, citing technical maintenance. KuCoin later took similar measures.
It is worth noting that the Fogo mainnet launch took place in January 2026 following a successful token sale on Binance, which raised $7 million at a project valuation of $350 million. The network's ambitious characteristics — a block time of 40 ms and reduced MEV influence — were intended to attract institutional traders, but now the very viability of the platform is in question.
A systemic industry problem
This incident fits into an alarming trend: just a few days before the attack on Fogo, Cosmos Labs called for suspending operations of networks based on the Cosmos EVM module after a series of hacks on three blockchains. The company later admitted that it had underestimated the danger of the vulnerability, which led to attacks on six networks.
My analysis: Halting the mainnet is an extreme measure that in itself causes reputational damage comparable to the loss of funds. For L1 projects, whose value directly depends on decentralization and continuous operation, such decisions call into question their fundamental promises. Investors should be extremely cautious with young networks that have a high concentration of supply held by the team — such attacks are often the result of weak internal security rather than external hacking.
