Sure thing! The physical cards are 6.4cm (2.5 in) x 8.9cm (3.5 in), printed on high quality 100% recycled paper. These cards are just the right thickness to feel satisfyingly sturdy, yet have a slight bend. They also have a cross-hatch texture, giving it a crisp look and hand feel.
The NFT version of Birdables cards is a digital version that you keep in your crypto wallet. This NFT is proof of your ownership and is verifiable on the immutable Polygon blockchain. Purchases of the NFT will come with access to the hi-res artwork, not available anywhere else. NFT's of Birdables cards are also more scarce than physical cards. Learn more about the rarity.
Great question! We donate a portion of profits to a bird conservation organization like the Cornell Lab of Ornithology , eBird , Audubon , etc. More details on this are still to come, as it is still unclear the cost of running this operation. All donation amounts & recipients will be available on this website, here, in the future.
To make sure Birdables is not contributing to the destruction of bird habitats, 100% recycled paper is used for all physical cards. No trees are cut down for the creation of the cards.
The Birdables NFT's (digital cards) are minted and distributed on the Polygon blockchain, which validates transactions using the Proof-of-Stake consensus model. This model consumes far less energy than the Proof-of Work model.
