# Introduction

> Your stocks, managed by an agent. Your spending, from a card you own.

<Info>
  Tozzecard runs on **BNB Chain mainnet** with real, small amounts. It is built for the [BNB Chain × Binance Web3 Wallet Tokenized Stocks hackathon](https://www.bnbchain.org/en/hackathons/tokenized-stocks). See [Status](/overview/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.

<CardGroup cols={2}>
  <Card title="The agent wallet" icon="robot">
    Your own Binance Agentic Wallet holds your tokenized stocks. An agent keeps them at your target split.
  </Card>

  <Card title="The card" icon="credit-card">
    A wallet made from your passkey. It holds USD1 and pays with Face ID. It never needs BNB.
  </Card>

  <Card title="Refills while the market is open" icon="clock">
    The agent learns what you spend and tops up the card before the market closes, so it never has to sell at weekend prices.
  </Card>

  <Card title="It can only send to your card" icon="shield-check">
    The Agentic Wallet sends only to addresses in its address book, which only you can edit, in the Binance App.

No seed phrase, no gas to buy, and no contract of ours: every contract involved belongs to Binance, BNB Chain or the token issuer.
