GIVEAWAY

This holiday season, we’re excited to announce a special collaboration between wave.space & Proof of Heart, a Bitcoin-native charity directory, allowing donors to give BTC without any intermediaries. As Bitcoiners, we believe in building a better future - and December is the perfect moment to give back and help others experience real, tangible change.

Together with Proof of Heart, we’re launching our Christmas Campaign, where your holiday season shopping can earn donations, a new wave.space hoodie or even get you 100% of your fees back!

Pay with your wavecard, earn donations to a charity of your choice & win epic gifts!

How to give twice this Christmas?

Between Dec 10th - Dec 25th, for every wavecard payment over 210,000 sats wave.space will donate 1,000 sats to the charity of your choice. You can submit your charity choice here.

We also encourage you to visit proofofheart.org directly and extend additional support to those in need!

Win a limited-edition wave.space hoodie, too!

Not only will you give back, but also each wavecard payment over 210,000 sats will earn you a chance to win our new wave.space hoodie! The more you shop, the better your chance to win the raffle.

Make the biggest card purchase? Get 100% of fees back!

Don't hold back your wavecard - spend Bitcoin. As a little extra competition among the community, we will give a 100% cashback on the fees charged to a single person who makes the biggest wavecard payment between Dec 10th - Dec 25th.

Spend Bitcoin. Support Bitcoiners. Spread love.

Whether you’re buying presents for friends, family, or yourself - your wavecard payments can help create real impact. Don't forget to also donate directly via Proof of Heart - a clean self-custodial register that already has 9 charities. No custody, no intermediaries. Just donors, charities and Bitcoin doing what it already does best.
