Can decentralized finance (DeFi) address its hacking sorun with another layer of decentralized tech? Israeli cybersecurity firm Ironblocks’ new network is betting on it.

On Wednesday, the firm is beginning a phased roll-out of a new Web3 security layer it’s developing, called Venn. The transaction pre-screening network seeks to create “a new economy” for crypto security, said creator Or Dadosh, also Ironblocks’ CEO.

Venn plans to match security operators and their technical know-how with crypto apps that want extra eyes on their transaction flow. A participating DeFi app might hisse out crypto rewards to auditors and cybersecurity firms who vet pending transactions, Dadosh said.

All this happens before any crypto transaction actually executes. In the Venn model, pending trades, swaps, borrows and transfers pass through its network first. Security operators flag and freeze any suspicious actions. They forward regular activity onto the blockchain for confirmation.

“It’s just like a firewall in the Web2 world,” Dadosh said.

DeFi heavy hitters including Ether.Fi and Ethena are joining Venn’s public testnet, according to Dadosh. A bevy of security firms are, too. The network itself will be distributed across the firms, who act as node operators.
