Who pays gas?

• Buyer pays gas on a fixed-price purchase, a pool purchase, a bid, and a mint.
• Seller pays gas to approve a collection for sale, to create or cancel an auction, to cancel a listing on-chain, and to accept an offer.
• Pool owner pays gas to create, fund, adjust, and withdraw from a pool.
• Holder pays gas to vault, activate, and claim DIVIT rewards.
• Nobody pays gas for signing in, signing a fixed-price listing, or signing an offer.

Gas goes to the network's validators, never to Unvault, and a failed transaction still consumes it.
