## What the demo does

The paywall demo lets you create a temporary paywall and share it with anyone. Visitors pay USDC to access the content behind it.

## How to use it

<Steps>
  <Step title="Go to paywall.renvoy.ai">
    Visit [paywall.renvoy.ai](https://paywall.renvoy.ai)
  </Step>

  <Step title="Create a paywall">
    Set a price, add your content, and provide your wallet address
  </Step>

  <Step title="Get a shareable URL">
    Each paywall gets a unique link
  </Step>

  <Step title="Share it">
    Anyone with the link can pay to access your content
  </Step>

  <Step title="Receive USDC">
    Payments go directly to your wallet on Base or Solana
  </Step>
</Steps>

## What's happening under the hood

When a visitor clicks "Pay":

1. The demo server responds with `402 Payment Required` and the price you set
2. The visitor's wallet signs a USDC transfer authorization
3. The facilitator (Renvoy sandbox) settles the payment on-chain
4. The demo server unlocks the content

The full x402 flow — from 402 response to on-chain settlement — happens in a few seconds.

## Try it yourself

The demo uses the sandbox facilitator and supports both Base Sepolia and Solana Devnet, so no real money is involved. You'll need testnet USDC in a wallet — get some from the [Circle faucet](https://faucet.circle.com/) (supports both Base Sepolia and Solana Devnet).
