Trait bids work the same way as collection bids, except for specific traits instead of the entire collection.
When a seller attempts to sell an item into a trait bid, the oracle will check that the item has the relevant trait in real-time. This ensures that trait bidders on collections that have changing traits are protected.
With that said, many collections store their metadata on a centralized server that they control. It is possible for items to change their traits after the oracle validates the item’s trait. Blur makes no guarantees about this scenario. It is outside of Blur’s control to stop collections from changing their traits dynamically.
Trait bids can also be used to earn trait bidding points on select collections. Trait floors can be less liquid and more volatile than collection floors. When you trait bid, only bid at prices you are truly willing to buy at. You should study the price history of that trait to get a sense of the market value. Do not base your pricing only on the trait listings and trait bids, because listings and bids can rapidly change.
