Connecting a wallet does not send money.

Use the same wallet to recover your download during its 24-hour window. This free signature sends no money. It also works after a reload or a lost connection.
What happens to my wallet and file?
The payment signature authorizes one USDC transfer to the recipient shown above. This page asks before signing or submitting it. Retries reuse that authorization.
After payment, the page checks the file’s size and SHA-256 fingerprint before offering Save. Confirmation means the file is available; your browser still needs to save it.
Your payment proof stays in this page’s memory. Recovery uses a separate, free wallet signature. Game saves remain on this device.
