Winter

Winter is a technical service that lets end users buy and mint NFTs with a credit card, aimed at consumer brands and developers who want blockchain capability without making users touch wallets or crypto assets. Its settlement design is that the buyer pays in fiat while the provider pushes the equivalent amount of ETH, SOL or MATIC directly into the minting contract at the prevailing token price, keeping fiat acquiring, fraud screening and chargeback handling on its own side and reducing on-chain settlement to an ordinary mint call.

Product components include a checkout component embeddable in third-party sites, hosted embedded wallets, minting and distribution through APIs, QR codes or NFC chips, and on-chain verifiable credentials. Settlement covers Ethereum, Polygon, Solana and other chains. In February 2024 Winter was acquired by Crossmint, an NFT and stablecoin wallet infrastructure company, with its cross-chain payment technology and consumer brand client base folded into the acquirer; since then it is usually discussed as a payment module of Crossmint.
