Our t-shirt designs are created by our very own ONCHAIN Wear design crew - Vlad & Octavian. They’re both long-run blockchain designers, having created visual identities for a lot of old-school & new-school blockchain projects (think Metamask, Gitcoin, Gnosis, Cellarius, UJO Music or SingularDTV for starters).

Everything is custom made, with the very rare exception when we might use pre-made stock elements in our design.

Because we ❤️blockchain, and we want to make it cool and easy to promote the awesome ideas and projects in this ecosystem. Check out About us to see our grand plans for ONCHAIN Wear.

Definitely yes, if you’re a product, team or company acting in the blockchain multiverse. We’d be excited to help you visually communicate with your current & future fan base.

Get in touch with our Co-Founder at
vlad@onchain-wear.com to discuss your needs, and we’ll get busy mining for ideas.

Definitely yes, if your designs are blockchain-related and we see their potential as wearable coolness. Send us your designs and some details about yourself at vlad@onchain-wear.com, and we’ll see how we can make your design famous 😎

We have a general rule that we always ask for permission to use a logo in our designs, even if the logos are under a Creative Commons license (i.e. Ethereum).
One exception to this rule is Bitcoin, and that's because they specifically mention on their website that making Bitcoin-branded t-shirts is encouraged.

Products & sizing

Our unisex t-shirts have a relaxed fit (wider bust & longer sleeves), and are slightly longer than an average t-shirt. 

  • 🔷 #Blockchain men - unisex t-shirts are true to size, so order your usual size.
  • 🔶 #Crypto ladies - unisex t-shirts are generally fitted for men, so consider ordering 1-size down for a flattering fit.

To find the right size for your new t-shirt, check out this size guide.

Our blank t-shirts are sourced from Guatemala, Nicaragua, Mexico, Honduras, or the USA. We promise you they’re 🌱100% eco-friendly & definitely no sweatshops.

Our printed t-shirts are made in several fulfillment centers around the world, so we can deliver them to you as fast as possible - the USA, Lithuania, Spain, Australia.

Hash, yes! We use the premium Bella + Canvas 3001 cotton fabric, so they’re soft and light, with just the right amount of stretch.
All t-shirts are side-seamed, with shoulder taping for extra durability, and pre-shrunk (no washing machine surprises).

Texture details:

  • Solid colors: 100% Airlume combed and ring-spun cotton
  • Dark Heather color: 52% Airlume combed and ring-spun cotton, 48% poly
  • Weight: 4.2 oz/y² (142 g/m²)
  • 30 single yarn

All our t-shirts are printed using DTG (Direct-to-Garment) printing. Through this process, speciality inks (water-based and eco-friendly) are absorbed in the fibers of the t-shirt, producing a smooth print and vibrant colors that stay true after numerous washing and wearing cycles.

As an exception, darker color t-shirts are printed on a white underbase, to make the colors pop. In this case, the print texture will feel just a bit rubbery - but definitely nothing like a vinyl print.

It’s probably from the deodor-ants! Poor joke aside, it’s just a temporary effect of the fixation agent* that’s applied during the printing process. It will go away after your t-shirt’s first wash.

*Fixation agents are used for all DTG prints, across the industry. They’re used to help the ink bond with the fabric as without them the ink would flake off the garment.

It definitely shouldn’t. Our Bella + Canvas 3001 t-shirts are pre-shrunk, exactly to avoid any bad surprises from your washing machine.

To give your t-shirt a healthy, long-lasting life, be sure to check our printed label for washing instructions.

Unisex t-shirts are designed to offer a flattering, relaxed fit to both men and women. As a result, there are a few differences between a unisex t-shirt and other cuts:

  • slightly longer sleeves
  • wider bust
  • overall longer (t-shirt height)

That is why we recommend #cryptoladies and #womeninblockchain order 1-size down from their usual t-shirt size. Check our size guide for more details & a happy wear.

Darker color t-shirts that feature a multicolored print (not just white) require a white underbase on which the print is applied. This white underbase ensures that the colors will be vibrant and true to our designs.
Occasionally, minor fabric stretches that occur during the printing process can lead to tiny mismatches between the white underbase and the colored print. This is usually a matter of millimeters.

This is an industry-wide technical limitation of the DTG process. We look forward to new discoveries 🤓

Fulfillment & delivery

We're using Printful for all our orders - they have a long history of doing print-on-demand (since 2013) and we're very happy with the quality of their prints and materials.

They also have a very rigorous quality control process that puts our mind at ease. 

We don’t hold a stock inventory. All our items are produced and delivered on demand, tailored to your order.

We ship worldwide, using our decentralized network of fulfillment and carrier centers. Your order will be routed to the fulfillment center that’s closest to your delivery address, for the best possible shipping times.
