You only need 1 card to access the portal.

If you have more cards then we have great news:

You can gift access to the course to another person, e.g. an employee, or family - this person does not need to have his/her card, you just need to plug the card into the course in the portal and enter the person's email. This is also a nice option if you want to gift someone access to the course e.g. as a reward.

You have access to eduworlds Founders - all original eduworlds cardholders will have access to "fun" generating other accesses for them. E.g. when 10 courses are created in a particular world, we will create a dedicated platform.


  1. 10 courses on CRYPTO are created (there are currently 3).
  2. We create a dedicated platform, focused only on CRYPTO.
  3. There will be an option to access NFT or purchase for PLN/USD/other currency.
  4. Relevant connections of eduworlds cards will additionally receive (because they have access to everything anyway) a certain amount of access to CRYPTO worlds, which they will be able to give away to friends or sell.

At the moment, each card allows you to unlock 1 course for a period of 2 weeks. The more cards you have, the more courses you can unlock at the same time.

Example: if you have 3 cards, you can unlock the courses Increase Your Productivity, Build a Community-Based Business, and Become a Better Negotiator (or any others) at the same moment. After two weeks, you leave those courses or unlock others.

A full list and description of the courses can be found here: CLICK

The card can be sold on the NFT marketplace (such as OpenSea). In the future, we plan to build our own marketplace where cards can be sold.

We send cards as soon as possible.

Purchase for PLN between 09.09.2022 and 30.09.2022 - we send the card after completing the survey, usually, in less than 24 hours after completing the survey the card should already be in your wallet.

Purchase for ETH or with OpenSea - the card should arrive in your wallet as soon as the transaction is completed.

A person with the eduworlds access card has access to a portal where they can choose 1 course every 2 weeks. Currently, there are 20 courses (18 in Polish, 2 in English). You can find a list of the available courses on our website. The list of courses will grow over time.

Access to the platform and courses is unlimited in time as long as you have an access card. Once you sell the card, you lose access to eduworlds.

You should follow 2 steps:

  1. Go to: and log in there through MetaMask. There you will be able to select a course using the card.
  2. Enter our Discord. Verification is required there in the #nft-verification channel.
