Tozzecard runs on BNB Chain mainnet with real, small amounts. It is built for the BNB Chain × Binance Web3 Wallet Tokenized Stocks hackathon. See Status for what is live today.

The problem
Tokenized stocks trade around the clock. The market behind them does not. From Friday 4pm in New York until Monday morning, the real stock price stops moving, while the token keeps trading on-chain. If you sell stock on a Saturday to pay for dinner, you sell at whatever the token happens to be worth that day, often below Friday’s close. And most crypto cards hold your money for you: you move your balance to the card company, and you spend theirs.The solution
Tozzecard splits the job between two wallets that you own.The agent wallet
Your own Binance Agentic Wallet holds your tokenized stocks. An agent keeps them at your target split.
The card
A wallet made from your passkey. It holds USD1 and pays with Face ID. It never needs BNB.
Refills while the market is open
The agent learns what you spend and tops up the card before the market closes, so it never has to sell at weekend prices.
It can only send to your card
The Agentic Wallet sends only to addresses in its address book, which only you can edit, in the Binance App.
The app at iPhone 15 Pro size, connected to the live API and showing the demo card. The name, number and CVV on the card are sample values; balances, holdings, targets and decisions are live.
