• Digital Currency for a Better World


  • Good for shoppers.

    With our project you soon you get rewarded for shopping sustainably and doing good. It's our way of saying "thanks."

    Do "good" things.

    Earn Goodcoins.


    Goodcoins will be your reward for helping out.


    Shop sustainably, recycle, volunteer your time - if it's good for the planet, it'll put coins in your digital pocket.


    You will earn'em.

    Now spend 'em.


    We will create the first

    "good" currency.


    You will be able to spend your Goodcoins on sustainable goods from a wide range of carefully selected shops.


    Feeling generous?

    You will be also also to donate them to charity or plant a tree to help Mother Earth.


    Ethical shopping

    made simple.


    We're very picky about

    who we work with.


    If Goodcoin will be accepted at a shop, you can be sure that whatever you're buying is responsible, green, or just plain good.

  • Good for shops. 

    Join a network of sustainable retail stores around the world.


    Reduced transaction fees.


    Boost your sales.

    Cut the cost.


    Sick of paying credit card companies out the wazoo? Goodcoin transactions will be available for a fraction of the cost.

    Instantaneous processing.


    (Well, nearly instantaneous).

    Clear your payments the same day.


    Soon we will be cutting out the middleman banks, we can get your money to you faster.

    Much, much faster.

    Serious data protection.


    We're obsessed with privacy.

    Leave the worrying to us.


    Our cryptographic scholars at Humboldt University will create a unique privacy system. Your data (and your customers' data) is safe and sound.

    Sustainable branding.


    Join a community of good companies.

    We'll help you get your green on.


    We only partner with companies that verifiably improve the world. Sign up to broadcast your sustainable goodness to the world.

  • Take a look what we are up to

    Don't worry, it's not too complicated


    Safety in code.


    Privacy by design.

    Made In Germany.


    We will use sophisticated cryptographic methods to guarantee a maximum level of security. We're embedding privacy directly into our currency - the proof is in the pudding.

    Open source.

    Fully transparent.


    Powered by the

    community for good.


    A system built on trust can only survive if we are transparent in everything we do. The code underlying Goodcoin will probably be open source - meaning anyone can take a peek and validate our claims.

    Globally integrated.

    Accessed anywhere.


    You will be able to send your money on a worldwide adventure.


    Feeling fed up with ridiculous currency exchange fees? Goodcoin will be able to be be transferred to your friends or loved ones anywhere in the world. We'll let you know all the (very small) costs beforehand - no hidden fees, no surprises.

  • Meet the teams.

    Four communities, coming together to form a new one.

    Plus, we made something pretty darn cool.

    Shopping for a better world. 

    We reward you for shopping sustainably. We'll provide the platform where you can find all of the Goodcoin partners. We're also responsible for selecting new partners - reach out if you're interested!

    Education through learning and research.


    Our crew is taking care of all the academic work underlying Goodcoin. Our cryptography and legal departments ensure your money is safe, your privacy is protected, and your transactions are legal.
