The legal team representing Polygon Labs, the firm behind the Layer-1 blockchain often dubbed the Ethereum killer, has proposed a framework that seeks to classify decentralized finance (DeFi) as “critical infrastructure” and overseen by federal cybersecurity agencies in the United States. Rebecca Rettig and Katja Gilman from Polygon Labs and emergent technology law firm Arktouros co-founder Michael Mosier published the proposal called “A Conceptual Framework for Combating Illicit Finance Activity in Decentralized Finance” on Monday.
