On March 11, Across Protocol proposed moving from a DAO and token model to a US C-corporation via a token-for-equity offer, arguing its current structure hinders institutional deals. The plan, which would let ACX holders swap tokens for equity or a buyout, has divided DeFi voices between those seeing it as a necessary step for stablecoin and RWA growth and those calling it a setback for open access and decentralization. The outcome of Across’ governance vote could signal whether more DAOs follow corporate-style legal frameworks or remain fully decentralized despite operational hurdles.
