Who is it voluntary for? The buyer or the creator of the NFT?

Does the tip get awarded to the creator after every transfer?

Is it voluntary for the buyer each time or is it only voluntary during the creation of the NFT and the first transfer?

So with pay_tips dispatchable call there is a concept of a receiver and a sender. It is voluntary for this extrinsic to be called, meaning "paying tips" is not a required part of buying/selling an NFT in this pallet.

Additionally, the receiver is defined within ItemTip struct:

/// Information about the tip.
#[derive(Clone, Encode, Decode, Eq, PartialEq, RuntimeDebug, TypeInfo, MaxEncodedLen)]
pub struct ItemTip<CollectionId, ItemId, AccountId, Amount> {
    /// The collection of the item.
    pub(super) collection: CollectionId,
    /// An item of which the tip is sent for.
    pub(super) item: ItemId,
    /// A sender of the tip.
    pub(super) receiver: AccountId,
    /// An amount the sender is willing to tip.
    pub(super) amount: Amount,

Notice how the receiver is associated with a collection and item id - the design decision here was to use pay_tips for a buyer to voluntarily pay the creator royalties:

pay_tips: Pay tips, could be used for paying the creator royalties.

There is work being done to create a coupled pallet that makes royalties a requirement of NFT sales. You can follow the work on this branch:

  • This is very helpful, thank you. Is there an estimated time frame for the coupled pallet royalties a requirement of NFT sales? Apr 25, 2023 at 15:57
  • It is actively being developed upon stay close.
