A VOX is a unique avatar with randomly generated traits. VOX are collectible ERC-721 NFTs. Each VOX is programmatically generated and provably unique, meaning that no two VOX will look the same.
VOX are built and live on the Ethereum blockchain as ERC-721 collectibles, which can be held in an Ethereum wallet, such as MetaMask.
Yes, VOX are designed to have various utilities. That means they will serve a purpose beyond just being a cute avatar that you can own and animate. VOX will be able to lock up GALA. There are additional utilities as well, such as play-to-earn rewards in Town Star and in-game benefits in Mirandus.
You will need to pay gas fees when purchasing your VOX Box in the Gala Store or Coinbase NFT (for Series 4) and also when you “reveal” your VOX.
