This is where things get serious.

Our community means everything to us, and we’ve decided that instead of setting an arbitrary price for our mint, we want to let our community decide through an auction. Given the specificities of our collection, we’ve decided to go with a fascinating auction mechanism: The bucket auction introduced by Doodle with their Genesis Box. This gives a large number of community members the option to position themselves, control their level of investment, and react to market conditions in an unrivaled way.

The price discovery public sale is a blind sale. Bidders can’t choose which Smurf character they are buying.

We will also reward the top bidders with unique incentives such as higher rarity Fusion NFTs:

  • The top 15% of bidders will get a Radiant Fusion NFT

  • The next 35% of bidders will get a Platinum Fusion NFT

  • The bottom 50% of bidders will get a Gold Fusion NFT

What is a bucket auction?

A bucket auction is a type of auction that allows the market to decide on the mint price. This type of auction is growing in popularity in NFT communities, and this page is dedicated to going over the details so you can be better informed when bidding on auction day! We will provide examples on this page and include different scenarios to make it easier to understand.

The Basics

A bucket auction is a way to set a single price for the whole auction, known as the "clearing price."

  • If you bid below the clearing price, you lose.

  • If you bid at or above the clearing price, you win.

  • If your bid is higher than the clearing price, you'll only pay the clearing price and will be refunded whatever you bid above.

  • You will receive as many NFTs as you bid multiples of the clearing price. For example, if your bid is at or greater than 1.5 ETH and the clearing price is 0.5 ETH, you will get 3 NFTs.

  • The clearing price is updated in real time and is visible to everyone.

  • You can increase your bid as many times as you want up until the end of the auction, but you cannot decrease it.

The clearing price

The clearing price is calculated by determining the highest price at which all NFTs could be sold at the same price without going past the total supply of NFTs.

The bucket mechanism

For all the Brainy Smurfs out there who want to get technical, the mechanism used to calculate the clearing price in the bucket auction is the "bisection method." This algorithm consists of repeatedly bisecting the interval between values and selecting the subinterval in which the function changes sign.

Example scenarios:

Let’s imagine two scenarios for an auction with 5 NFTs available and six people bidding in the auction.

In scenario #1, we have the following bids and clearing price:

BidderAmount & QuantityClearing PriceResult


1.1 ETH

Bid A gets 2 NFTs and is refunded 0.1 ETH


1.0 ETH

Bid B gets 2 NFTs


0.6 ETH

Clearing Price = 0.5 ETH

Bid C gets 1 NFT and is refunded 0.1 ETH


0.4 ETH

Bid D is refunded 0.4 ETH


0.3 ETH

Bid E is refunded 0.3 ETH


0.1 ETH

Bid F is refunded 0.1 ETH

In scenario #2, we have the following bids clearing price:

BidderAmount & QuantityClearing PriceResults


1.1 ETH

Bid A gets 2 NFTs and is refunded 0.3 ETH


0.7 ETH

Bid B gets 1 NFT and is refunded 0.3 ETH


0.5 ETH

Bid C gets 1 NFT and is refunded 0.1 ETH


0.4 ETH

Clearing Price = 0.4 ETH

Bid D gets 1 NFT


0.3 ETH

Bid E is refunded 0.3 ETH


0.1 ETH

Bid F is refunded 0.1 ETH

Frequently Asked Questions:

Can I bid on multiple NFTs in a single auction?

You can place bids from as many different wallets as you want. If you want to bid on multiple NFTs from the same wallet, you will have to set your bid to match the quantity you select. For example: If you want to bid on 3 NFTs and the clearing price is 0.5 ETH, you will need to bid at or above 1.5 ETH (at 0.5 ETH each).

What is the difference between Access Crystals and the auction?

The auction is for the actual Smurf PFP. Once the auction is over, winners will receive a random Smurf PFP at the clearing price.

Access crystals are tickets to mint a particular Smurf PFP at a discounted price. Several days after the auction, crystal holders will have the opportunity to mint their Smurf PFP for the clearing price set during the auction, minus the discount associated with their crystal.

Can I choose which Smurf I want in the auction?

No. Auction winners will receive totally randomized Smurfs; neither the character nor the rarity will be known until the reveal in May 2023.

If you want to choose a particular Smurf character, the only way is to win an access crystal through gamification on our app or by purchasing one on OpenSea.

When will I know the rarity and be able to see what my Smurf PFP looks like?

All Smurfs from the Legendary collection will be revealed at the same time. The reveal experience is scheduled to take place in May 2023. Stay tuned for a precise date and an invitation to the reveal experience.

Can I see what the clearing price is, or will it be hidden until the end of the auction?

The clearing price will be visible during the auction. You can change your bid as often as you like.

What happens if my bid is below the clearing price?

If your bid is below the clearing price, you will not win any NFTs and your funds will be reimbursed to your wallet after the auction.

Can I change my bid?

Yes, you can increase your bid as many times as you want while the auction is ongoing. However, you cannot decrease or cancel your bid.

Can I cancel my bid?

Unfortunately, you can not cancel your bid. However, if your bid is below the clearing price, it will be refunded automatically at the end of the auction.

Will there be a minimum bid price to enter the auction?

There is a minimum 0.1 ETH deposit to be able to place a bid. This deposit is added to your bid to create your total bid amount:

0.1 ETH deposit + 0.2 bid = 0.3 total bid

If you do not win, your total bid will be refunded in full, including the deposit.
