In the 2000s, the world came online. Now, it’s coming onchain—and we’re making it happen, faster.
Crossmint is a one-stop-shop developer platform for companies building onchain. We completely remove the complexity of building and using blockchain applications. Our platform provides all of the infrastructure companies need to build apps that scale to millions, without needing to orchestrate multiple vendors. It lets them create experiences that mirror the traditional web with familiar features like FaceID and email sign-ups, while eliminating gas fees and other friction points.
Our suite includes wallets, payments, onboarding, on/off ramps, tokenization, AI agent infrastructure, and other essential onchain building blocks, across 40+ blockchains.
We’re building a world where companies can get their entire blockchain backend, through a few lines of code, to build the next generation of the internet. Join us!
