Introduction

Enterprise-grade wallets with best-in-class security

Crossmint’s whitelabel wallet solution, trusted by leading enterprises like Mastercard and Red Bull, allows you to add web3 capabilities to your site, app, or AI agent via a simple API.

Crossmint’s wallets are programmable, enabling sophisticated transaction logic, granular permissions, account recovery mechanisms and more. You control who can approve transactions and what permissions different entities have, all while maintaining the security guarantees of the underlying blockchain.

How Does it Work?

1. Generate Wallets: Easily create wallets using headless APIs. Generate wallets during checkout or when airdropping NFTs to email addresses without requiring users to have a wallet set up in advance.
2. Seamlessly Run and Sign Transactions: Handle tasks like fetching blockchain data, signing transactions, and transferring assets effortlessly directly within your app.
3. Integrate with other Crossmint Products: Enable NFT minting and allow users to pay with credit cards or crypto, all while leveraging the same simple APIs.
4. Leverage web3 Composability: Enable users to connect their wallets to third-party platforms via Wallet Connect or Crossmint Connect.
