What is a collectible?

A crypto-collectible is a one-of-a-kind non-fungible digital asset.

What?!? I know, ok, a little bit simpler:

Collectibles are unique digital goods that can be exchanged. Think of collectibles as a kind of object only in digital form. These objects can represent cards, things, images, and much more. Collectibles come in many varieties, the most famous are CryptoKitties or Cards like from Gods Unchained.

How do I get my first card?

You are now equipped with Meta Mask and want to have your first card? Great!

On your way to a Marble Master, you have several possibilities to get cards. You can buy / auction cards, create cards yourself, or win cards.

Buy / auction cards

Let's start with the easier way. Buying cards by auction. On OpenSea you will find a wealth of cards. I think everyone can find something here.

Create cards

Yes, you can create your own cards! That's what's so cool about Marble Cards. You have to be aware of a few things. Not every URL is available at the moment.

With the Marble Plugin, you can quickly check which URL is still available. So first find a URL that is still available and for which you are able to create a card for it.

All further steps are explained under How to marble, how can I create a card?

Win cards

Marble Cards has many competitions, lotteries, and giveaways.
At the moment all this action is being held in the Discord. Just take a look at the Discord. Here you will find not only giveaways but also like-minded people :-)

Are more sites gonna be added to marble?

Yes, there will definitely be other addresses that can be used for cards. At the moment one address is added every two weeks. However, since the ETH gas price has skyrocketed to unimagined heights and transferring cards is extremely expensive, this is always decided at short notice. Have a look at the Discord Chat here.

I cannot submit my cards to the arena

In order to place cards in the arena, you must have set a username. Under "My Collection" next to your data you can edit your username.

Can I marble from Wikipedia?

No this is not possible at the moment. They're genesis cards. The first cards to be marbled... they are for prizes, tournaments, and something like that. This includes other addresses such as Twitter and YouTube. Such addresses will be enabled in the future but this will be done in a coordinated way and only when Marble Cards is running stable and the off-chain solution is available.

How much does it cost to mint (create) a card?

This is not easy to answer. In the beginning, creating a card cost 0.02 ETH. In the meantime, since the gas price is extremely high, creating a card costs 0.03 ETH. This can of course change.

But you have to consider the transaction fees. Because of the high gas price, creating a card can cost 0.05 ETH. Here you have to see how expensive the gas price is.
