Mexico City Collection Drop
Status: Closed, outdated, comment period ended. For the final sale mechanism, review our tokenomics here.
tl;dr
We propose a new drop mechanic for the Mexico City collection that increases the number of available units while maintaining price discovery across individual artists in the collection through secondary market activity.
Here is the abbreviated plan:
- Announce the complete lineup for the Mexico City collection prior to the drop and release eligibility requirements for the drop (e.g. require holding a GTMX and a Citizen to participate in the drop)
- Conduct a GTMX sale to fund the ongoing operations of the team between London and Mexico City, as well as secure real-estate and necessary licenses to operate in Mexico
- Conduct a dutch auction with a rebate to purchase a “blind” mint pass for 1 of n artists in the Mexico City collection. All mint pass buyers pay the same final clearing price. The mechanic encourages participants to enter at the highest price they are willing to pay, but enables everyone to end up paying the lowest market clearing level (or resting price).
- Reveal the corresponding artists for the blind mint passes after the auction ends but before the event starts
- Conduct the event from November 14-21 and mint the Mexico City collection artists IRL
Background
In An improved auction method for bundled token drops (e.g. city collections), we outlined several first principles for designing drop mechanics:
- Fairness: don’t completely lock low-income people out of participating, give them at least some chance to get in. For token sales, there’s the not quite identical but related goal of avoiding high initial wealth concentration and having a larger and more diverse initial token holder community.
- Don’t create races: avoid creating situations where lots of people are rushing to take the same action and only the first few get in (this is the type of situation that leads to the horrible auctions-by-another-name that we saw above).
- Don’t require fine-grained knowledge of market conditions: the mechanism should work even if the seller has absolutely no idea how much demand there is.
- Fun: the process of participating in the sale should ideally be interesting and have game-like qualities, but without being frustrating.
- Give buyers positive expected returns: in the case of a token (or, for that matter, an NFT), buyers should be more likely to see the item go up in price than go down. This necessarily implies selling to buyers at below the market price.
- Maximize artist revenue: If artists do well, we do well. We want to continue to produce outstanding results for our Artist Partners and having a reputation for positive financial outcomes is a key aspect of that relationship.
- Reward existing CryptoCitizens: Community members who have participated in ecosystem building, governance, and minting events should have a higher-than-average chance of participating in drops.
Assumptions
- All 333 GTMX holders intend to participate in the Mexico City Collection drop
- We can bundle (and unbundle) multiple mint pass smart contracts under the same collection on OpenSea during the pre-reveal period
- Artists are in favor of us experimenting with a novel drop mechanism
The Plan
One more time for the people in the back:
Pre-Drop
- Announce all of the participating artists in the Mexico City Collection
- Announce the drop dates for both GTMX tokens as well as the Mexico City Collection drop
- Sell 283 GTMX tokens via a
fixed price (e.g., 3 ETH) saleDutch auctionfixed price with a presale on [app.brightmoments.io](http://app.brightmoments.io/ (see comments below for discussion on this) - Take a snapshot of all GTMX holders 24-48 hours before Mexico City Collection drop
The Drop
Tokenomics
- Starting price: x ETH
- Resting price: x-C ETH
- Price paid by Individual Mint Pass Buyers: Market Clearing sellout level or Resting price
- Price paid by Mint Pack Buyers: Purchase Price at time of transaction confirmation
- Auction Duration: 1 hour
- Tokens sold: ~70% of total mints (i.e. if there are 8 artists with 100 mints each, the drop would sell 560 mint passes)
-
Eligibility criteria:
- Mint Pass: CryptoCitizens who hold at least 1 GTMX token.
- Mint Pack: Buyers must hold a GTMX + a CryptoCitizen from each city (e.g. CryptoGalactican, CryptoVenetian, CryptoNewYorker, CryptoBerliner, CryptoLondoner)
& a minimum ETH amount (e.g. 8 ETH the day before the sale to meet the minimum)
- Wallet Limiter: 3 Mint Passes per GTMX held, or 1 Mint Pack per full CryptoCitizen set held
Purchasing
- At each price band, collectors can purchase a Mint Pass that is randomly selected from a blind assortment of n artists
- There is also a button to purchase a Mint Pack for the cost of n artists * the current price band (e.g. if the price band is 1 ETH and there are 8 artists, the price of a mint pack is 8 ETH). This is the only scenario when purchasing buyer pays non-market clearing price.
Here is a rough mockup of a potential UI based on the Mirror Dutch Auction template
Post-Drop
- Once the drop is complete, buyers will hold a Mint Pass corresponding to a specific artist ID (e.g. Mexico City Artist 1, Mexico City Artist 2, etc.)
- All Mint Passes will be grouped into a single collection on OpenSea (e.g. Mexico City Collection Mint Passes) to allow for easy filtering and liquidity for buyers
- We will reduce secondary fees on pre-revealed Mint Passes to 0% on OpenSea to facilitate low cost trading between collectors
- No one (not even the Core Team or the artists) will know which artist a given ID corresponds to
- We will allow some time for secondary trading for those who want to diversify their collection (i.e. if you ended up with two Artist 1 Mint Passes, you can trade with someone that has an Artist 2 mint pass)
- After a period of time has passed, we will use RCS to assign participating artists to ID numbers. This information will be published via a signed post using the brightmoments.eth Mirror page.
- After the reveal, the metadata for each Mint Pass will be updated to reflect the artist name. Additionally, the collections will be broken out into separate collections to improve liquidity for specific artists and to accurately reflect floor prices. At this point, we will reinstate secondary trading fees to compensate artists who are benefiting from secondary market activity based on their reputation.
Summary
We believe that this drop mechanism achieves the stated goals from An improved auction method for bundled token drops (e.g. City Collections) while maintaining accurate price discovery for an arbitrary number of artists.
Reviewing the goals:
Fairness: A-
- This mechanism assures that all GTMX holders will have an opportunity to participate in a dutch auction where supply of Mint Passes > Number of Individual Participants. Not every potential buyer is guaranteed a mint since it may sell out, but they will have the opportunity to purchase at a price that is fair to them.
Don’t create races: A-
- The dutch auction mostly addresses this issue. It may become a race in the final price band, but the majority of the auction will not depend on when you submit your transaction due to the rebate mechanism.
Don’t require fine-grained knowledge of market conditions: A-
- Dutch auctions are great for this, since you can simply purchase at a price you are comfortable paying. The bands should provide some indication of expected value, but the blind nature of the passes does not advantage sophisticated buyers over novices.
Fun: A+
- If nothing else, this will certainly be an engaging drop. We hope it will also be fun and not too stressful.
Give buyers positive expected returns: B
- This is an area that we have concerns. The price of the Mint Pass should be the average expected cost of the individual artist Mint Passes post reveal. There is quite a bit of guesswork that will go into this, but it means that the clearing price of the blind passes may represent a premium to the expected value of a particular artist’s Mint Pass. However, due to the token-gating limiting the number of participants in the dutch auction, we believe that open market post-sale demand may make up for the premium paid in the dutch auction.
Maximize artist revenue: A-
- Artists will split the proceeds of the dutch auction, as well as have the opportunity to benefit from secondary sales post-reveal.
Reward existing CryptoCitizens: B+
- This area needs refinement. Ideas include offering a GTMX discount for Citizens up to a certain amount, setting aside an allocation of Mint Passes to be sold to a randomly chosen subset of Citizens following the dutch auction, and increasing the purchase allocation during the sale for GTMX holders who also hold Citizens.
Next Steps
- Gather feedback from CryptoCitizens and broader generative art community
- Confirm drop mechanism & Mexico City collection artists
- Announce artist lineup and sale dates
- Do the damn thing
FAQ
Q: Why not set a fixed price for the mint pack / mint passes?
A: It’s difficult to accurately set a single price for a wide range of artists across various mediums. Setting varying prices creates a large amount of complexity based on subjective measures of previous work, especially for projects that are still in development.
Q: Why not reveal the artists immediately after the drop?
A: After the drop, it will be possible for individual mint pass buyers to own multiple tokens from the same artist ID. In these situations, we want to allow time for buyers to diversify their mint pass holdings to achieve a better distribution of mints across the collection?
Q: How will you conduct the rebate?
A: TBD. There are (at least) two potential options:
- Conduct the rebate manually. After the sale, the Core Team would review the on-chain transactions to the marketplace contract and return any funds exceeding the clearing price for mint pass buyers.
- Build a rebate function directly into the smart contract.
Q: How do I know that the artists IDs are truly random?
A: We will use ChainLink VRF to produce a series of 10 random numbers that will be used to map the artist IDs to the corresponding London Collection artist. See Control as Liability for rationale on why we (the Core Team) nor the artists would even want to know this information.
Q: How do you decide how many Mint Packs are available?
A: TBD. We will probably do something like 20% of the available mint passes, or ~200 Mint Passes / 20 Mint Packs total. This number should be large enough to meet the number collectors who hold a Citizen from every city, but not so low that it reduces supply artificially.
Q: Why not do separate dutch auctions for each artist?
A: Price fatigue. Artists that conducted dutch auctions earlier in the series would have an advantage over later artists, as collectors will likely lose interest / expend liquidity.
Q: Why not allow people to choose a specific artist ID during the drop?
A: We want to reduce the probability of a single actor cornering the market on a specific artist ID to extort high prices from those who want to assemble an a la carte mint pack in secondary trading. Assigning random mint passes during the drop will reduce the chances of this happening.
Q: Will there be a wallet limiter during the auction? Why?
A: We think so. Since this is a token-gated auction, a wallet limiter doesn’t face the same exploits as in a typical drop, when a determined actor can simply fund multiple wallets. Due to the GTMX requirement, there is a non-trivial economic cost to minting more tokens that permitted by the limiter. Having a limiter increases the chances that everyone who meets the eligibility requirements will be able to purchase a mint pass.
