Floor price

The floor price is computed as the minimum of the active sell orders for a collection on a specific marketplace at a specific moment. That is why the floor on OpenSea, Blur or Magic Eden can differ for the same collection. It is a noisy and manipulable metric: a very low accidental listing, wash trading or a mass delisting can move it without any change in real value, so it should be read with caution. In thinly traded collections it is a weak reference, and aggregators try to clean it by excluding outliers.

It is the most widely used valuation metric for the collections segment. Multiplied by supply it yields an estimated market cap for the collection, it serves as a quick benchmark, and it is used as the basis for NFT-collateralized loans and floor derivatives. It is worth remembering that it is a volatile figure, so no concrete value should be fixed in evergreen content.

It is not a technical standard but a market metric that emerged with the liquidity of profile-picture collections. Services such as NFT Price Floor and the OpenSea stats tab publish floors per collection. Blur introduced collection-level bids that act as a demand floor, and protocols like NFTfi or BendDAO use the floor to value collateral. For any service that relies on a reference valuation, this volatility is the key thing to account for.
