To vote on Hermes Protocol, users need to vote lock their HERMES. By doing so, participants can earn a boost on their provided liquidity and vote on all DAO proposals. There is no minimum voting power required to vote.
veHERMES stands for vote escrowed HERMES, it's a locker in NFT form where users can lock their HERMES for different lengths of time to gain voting power. Users can lock their HERMES for a minimum of week and a maximum of four years. As users with long voting escrow have more stake, they receive more voting power.
