$75M Tectonic Exploit Blamed on Weak Collateral Controls, Not Oracle Failure

A recent exploit on Tectonic, a decentralized lending protocol on Cronos, resulted in an estimated $75 million loss. According to an on-chain researcher, the attacker manipulated the price of TONIC, causing it to rise about 100-fold in just 20 minutes.

The inflated tokens were then supplied as collateral to Tectonic, allowing the attacker to borrow assets with more established liquidity. However, RedStone's co-founder Marcin Kazmierczak disputed that an oracle failure was responsible for the exploit.

Kazmierczak argued that the oracle accurately reported TONIC's price in the pool it monitored, but Tectonic allegedly accepted the reading without checking whether the token could be sold at that valuation in meaningful size. He claimed that a properly set borrow cap linked to executable liquidity would have limited the losses.
