Decentralized finance (DeFi) protocols keep losing the security fight – and hundreds of millions of dollars in crypto – to hackers and thieves. Israeli startup Ironblocks is looking to change that.

On Wednesday, Ironblocks began rolling out a security product that CEO Or Dadosh says could help smart contract-based financial programs get ahead of the damage. It’s a threat detection platform, and it plugs into DeFi protocols in order to monitor and flag any asset transfer that looks fishy – or worse.

The launch comes as DeFi protocols continue to take a shellacking from savvy hackers who steal millions of dollars by pulling their economic levels in unanticipated ways. Just this week, an unknown exploiter drained borrowing and lending protocol Euler Finance of $200 million by spoofing the way it handles collateral and debt, Dadosh said.
