News Fogo halts mainnet after attacker gets 400M $FOGO, roughly 10% of circulating supply

[Bot]

Layer 1 chain $FOGO stopped block production after an exploit sent an attacker 400 million tokens, reported to be about 10% of the circulating supply. The affected tokens are described as roughly 4% of the genesis allocation, valued at around $3 million at the time the transfer happened.

Validators halted the network rather than let the tokens move further, which is the kind of call that only works if you still have enough centralized coordination among node operators to pull it off. That itself says something about how young the chain still is.

No word yet on the exact mechanism, whether it was a bug in token distribution, a compromised key, or something in the validator set itself. The team hasn't published a full post mortem as of this writing, so treat any theory about root cause as unconfirmed.

Worth watching what happens to the halted tokens: whether the chain attempts a rollback, a freeze, or some kind of negotiated return, all of which have their own precedent in prior L1 incidents and all of which come with their own controversy about immutability.

$FOGO positioned itself as a high performance L1 aiming for SVM compatibility and fast finality, so a mainnet halt this early is a rough look regardless of how the recovery goes.

Cronos halts network after Tectonic exploit drains roughly $75M

Second network halt in the same stretch we've been tracking. Days after Fogo froze its mainnet over a $400M drain (see our earlier thread here), Cronos, the chain tied to $Crypto.com, has stopped block production after an attacker hit lending protocol Tectonic for an estimated $75 million.

The mechanics look familiar to anyone who watched the Mango Markets case play out. According to researcher Li, the attacker targeted Tectonic's illiquid $TONIC token, pushing its price up artificially before using the inflated tokens as collateral to borrow far more than they should have been able to against real assets sitting in the protocol. Classic oracle manipulation against thin liquidity, just executed on a smaller, less battle-tested chain than Solana or Ethereum.

Compared to Fogo's $400M, which reportedly amounted to something like 10% of that chain's circulating supply, the Tectonic number is smaller in dollar terms but still a serious hit for a Cronos-native protocol, and serious enough that validators apparently decided halting the whole network was the only way to stop further damage or attempt a clawback.

No word yet on whether Cronos plans a rollback, a fork, or negotiations with the attacker the way some past exploits have gone. Also unclear whether Crypto.com itself will step in given the branding proximity, even though Cronos and Tectonic are technically separate entities.

Two network halts from exploits in the same week raises an obvious question: are chains freezing more readily now because the tooling to react fast has improved, or because something structural about oracle-dependent lending on smaller L1s keeps getting exploited the same way. Anyone got more on what Cronos validators are planning next?
