Cronos network halts after $75 million Tectonic exploit
Security & Exploits ·
The Crypto.com-linked blockchain paused block production following a large-scale attack on its top lending protocol.
The Cronos network went offline after an exploit targeting Tectonic, described as its largest lending protocol, resulted in an estimated $75 million loss, according to The Block. The network's halt followed the detection of the attack, a defensive measure aimed at limiting further movement of funds while the incident was assessed.
The exploit centered on price manipulation of Tectonic's native token, TONIC, which the attacker used to borrow approximately $75 million from the protocol, per reporting from wublockchain.xyz. By skewing the token's price, the attacker was able to secure loans against inflated collateral values, draining a substantial portion of the protocol's liquidity before the broader network was stopped.
Multiple accounts of the incident converge on the same figures: a $75 million loss tied to Tectonic, and a subsequent halt of the Cronos network itself rather than an isolated pause of the affected protocol. That the underlying chain was taken offline, rather than just the lending market, points to the scale of the exposure and the urgency with which network operators responded once the manipulation was identified.
Cronos Network confirmed the halt through its own channels, with an update posted at x.com. Four distinct sources have reported on the exploit and subsequent halt, indicating the incident drew immediate attention across crypto media as details emerged.
What remains unclear is whether any of the borrowed funds will be recovered, how long the network halt will persist, and what remediation steps, if any, will be applied to Tectonic or affected users. Also unresolved is whether the network will resume normal operations before a full post-mortem of the price manipulation mechanism is completed.
