Wintermute founder and CEO Evgeny Gaevoy said on Dec. 26 that the firm will vote against Aave's ARFC governance proposal to transfer control of the protocol's brand assets to token holders, BlockBeats reports. He argued the proposal lacks concrete details on how the entity holding the front-end and brand would be governed, whether it would be profit-driven and how it would operate. Gaevoy called token value capture the core issue facing AAVE and pointed to a clear mismatch in expectations between AAVE Labs and large token holders. The Aave community launched a Snapshot vote on the ARFC proposal, which seeks to define ownership, usage rights and terms for Aave's brand assets and intellectual property—including domains, social accounts and naming rights—and to grant the DAO control over them, with voting open until Dec. 26.
