{"ops":[{"insert":"The Dai Card application, a simple browser-hosted wallet, allows users to transact instantly, cheaply, and securely in Dai.\nSimilar to a physical debit card, users “top up” their Dai Card balance by depositing Eth (or Dai) directly to their Dai Card address, which gets instantly swapped into Dai and represented as USD in-channel. Users can withdraw their funds directly into Eth without needing to pay gas, dramatically simplifying the “cash out” experience.\nBecause the Dai Card runs on the Ethereum mainnet in payment channels, user funds are always self-custodied and can be exited regardless of the hub’s availability. Integrating Connext’s system into custom applications is also simple, requiring only a basic knowledge of Javascript.\n"},{"attributes":{"bold":true},"insert":"Why is it called a Card?"},{"insert":"\nJust like a debit card, you can top up your Dai Card with balance and spend it everywhere through your day. We want users to think of that experience as different from but complimentary to wallets where you typically store much larger amounts and transact less frequently. This way, wallets can also easily integrate Card functionality!\n"},{"attributes":{"bold":true},"insert":"Goals"},{"insert":"\nWe created the Dai Card for a few reasons:\n"},{"attributes":{"bold":true},"insert":"To solve the difficulty of doing fast, cheap, stable payments "},{"attributes":{"italic":true,"bold":true},"insert":"today"},{"insert":", in the simplest way possible without making too many trust concessions.
