About Crossmint

Crossmint is building the infrastructure layer for web3, starting with NFTs. We have built a suite of powerful APIs for enterprises to create and distribute NFTs at scale. We are trusted by over 7,000 brands and developers, like Magic Eden, Rarible, Diageo, Cinemark, Tomorrowland, and McFarlane Toys. Our NFT fiat on-ramp is the leading solution in the market, powering marketplaces with billions of dollars of transaction volume. It enables anyone to purchase NFTs in one minute, from any device, even if they don’t have a wallet. Our minting APIs provide scalable and reliable infrastructure to create and edit NFTs on-demand, abstracting the complexity of contracts, gas fees, and wallets from both sellers and buyers. Our wallet-as-a-service infrastructure enables the creation of wallets through simple flows and API calls, abstracting seed phrases, and creating experiences accessible to the entire world. At Crossmint, we believe that NFTs will become the standard to represent ownership digitally, bringing efficiency to the markets and unlocking trillions of dollars in value. We are building the infrastructure layer to make that happen, faster.
