PLUGINS EVENT MARKETPLACE BUY

Plugin Event: marketplace.buy

marketplace.buy runs inside the listing transaction after the open listing is locked and before the buyer is charged. BuyerPrice is mutable and already includes native commission.

host.Events().Listen(event.MarketplaceBuyName, event.ListenerOptions{}, func(_ context.Context, current event.Event) error {
	purchase := current.(*event.MarketplaceBuy)
	purchase.BuyerPrice = purchase.BuyerPrice * 80 / 100
	return nil
})

The final non-negative value is the amount actually charged and published in the committed sale fact. Cancellation rolls back charge, transfer, and sold state.
