Why Flair?
Flair covers most prevalent use-cases for NFT and Web3 projects from crypto games and e-commerce to web3-powered communities and dapps. Never build the things that are already built. But wait, there is more...
Developer-friendly
We provide open-source smart contracts, frontend SDK, trustless APIs, and a handy dashboard. Fully composable & customisable.
Your contract, your code, in your ownership.
End-to-end integration
Flair aims for an end-2-end set of features, so you don't have to jump across multiple providers and get everything you need in one place.
Deal with fewer number of platforms.
No vendor-lock
Architecture of Flair respects ethos of decentralisation, so your business is not tied to Flair.
You can continue w/o Flair (but you'll miss us)
Built for Developers.
You have full control over every detail as a developer, from smart contract code to frontend components and customize for your own site and style.

Loved by Builders.
Working with Flair has been great! From our first meeting, Aram and Kasra have been nothing but helpful, supportive and problem-solving. With Flair, Castle of Blackwater was able to deliver a state-of-the-art NFT staking protocol for our community. We look forward to our future collaboration.
Working with Flair has been such a great experience. We've had hands-on support from day 1 and Kasra and Aram have acted as advisors to us on more than one occasion. They are genuinely invested in our success. One of the best technology partners we have had the pleasure of working with!
By using Flair platform, we were able to get a turnkey MVP in one digital meeting. The tech and tools available on their platform is truly unparalleled for game developers and Web 2 accessibility. The flair team is god-tier. We just saved months of development and headache, thank you!
