Our motivation to create CAPS arose from the main problem in the current NFT market, which is that many buyers have no practical use for the images they purchase.

In the CAPS game, however, you can actually play with your collectibles, and as you do so, they gradually lose quality, forcing you to develop your own unique strategies within the game’s economy.

What it does

Players can collect caps, which are similar to the milk caps that many of us remember from the game in the 90s. Each collection production is limited, for example, “Monsters 1” is limited to 100,000 caps (in 4 networks), which creates long-term interest for collectors. Additionally, each cap has a rarity, with some being more exclusive than others.

To obtain a cap, players can use a vending machine by purchasing tickets and pushing the button to receive a random cap from the collection.

Every collection has its basic value halved from the previous one.

Starting from the 2nd collection, tickets can only be purchased with the native currency, which makes the economy fully dependent on the market.

Users can play with caps and win or lose them.

Each game session decreases the condition of the caps.

Scratched caps are more valuable than fresh ones during the burn process for game currency. However, packed caps can also hold special value for collectors. Thus, there is a supply/demand curve.

How we built it

Started Aug 2021 now it’s almost 2 years but June 2023 was first collections announce time, and now we are in production, continuing to develop the new updates.

Challenges we ran into

Random. Chainlink is too expensive, so we need to convert to LINK. Instead, we have chosen API3 QRNG, which is free, and the only requirement is to pre-cover the gas when users call for random numbers.

Gas limits. It is currently impossible to fulfill the 1-2M gas callbacks because the API3 QRNG’s airnode has a maximum gas limit of 500k. However, we are developing a game model where users can pay the gas for their specific actions and claim the amounts they have won.

Accomplishments that we’re proud of

The working full-cycle game economy concept where every item has a value.

What we learned

The world built on trade-offs.
