A reentrancy onslaught allows an attacker to drain funds of a susceptible declaration by repeatedly calling the retreat relation earlier it updates its balance. This onslaught has been commonly utilized to exploit several DeFi protocols.
BlockSec, a blockchain information firm, said the reentrancy onslaught could perchance hazard each pools with wrapped Ether (WETH).
While it was unclear however overmuch was stolen from Curve Finance’s stablecoin pools, immoderate estimates suggest that arsenic overmuch arsenic $70 cardinal mightiness person been stolen.

CRV’s terms tank
The exploit has made Curve’s CRV token highly volatile, with its terms dumping by astir 15% to $0.64707 astatine the clip of writing, according to CryptoSlate’s data.
