Dai Card is a browser-hosted wallet designed to facilitate seamless transactions using Dai, akin to a physical debit card. Users can 'top up' their Dai Card by depositing ETH or Dai. This deposit is instantly converted to Dai and represented as USD within the payment channel. A notable feature is withdrawing funds into ETH without gas fees, simplifying the cash-out process.

Dai Card leverages Ethereum mainnet payment channels to maintain high security and accessibility for user funds. As a self-custody wallet, funds remain user-controlled even if the operating hub is unavailable. This setup ensures transactions are secure, and users can exit funds at any time.

Dai Card offers a user-friendly interface with the convenience of a debit card, enabling quick and inexpensive transactions in Dai. Unlike many other wallets, Dai Card allows users to cash out in ETH without gas fees, making the experience of withdrawing funds more straightforward and cost-effective.

Dai Card is powered by Connext, which simplifies integration into custom applications. With a foundation in JavaScript, developers can effortlessly incorporate Dai Card's payment channels into their projects, expanding functionality and offering seamless application-wide transaction capabilities.

Dai Card stands out in the crypto industry by combining ease of use, cost-efficiency, and high security. Its ability to facilitate instant transactions, manage assets conveniently in a Web3 environment, and provide self-custody solutions reflects the growing demand for functional and user-centric wallets in the decentralized ecosystem.

For troubleshooting Dai Card, ensure your browser supports Web3 extensions and verify your internet connection. If you encounter issues with deposits or withdrawals, check that your balance is sufficient and that the Ethereum mainnet is fully operational. For technical details or additional support, consulting Connext's integration documentation may be beneficial.
