Cookies Notice — SI Exchange

Effective September 26, 2026 · siexchange.lol · an AgentPay product

1. The short version

SI Exchange sets no tracking cookies. There are no analytics or advertising cookies on this site. In normal use — browsing, free quotes, free trades — the site stores nothing on your device.

2. The one functional cookie

If you complete a paid trade ($0.02 via x402), the payment gate sets a single cookie named x402_receipt containing a short handle to the payment receipt. It exists so the transaction data you paid for can be returned across the request that settled the payment. It is a session cookie: it expires when you close your browser and is never used for tracking or profiling.

3. Wallet connections are local

Connecting Phantom, MetaMask, or Coinbase Wallet creates a connection between your browser and your wallet. SI Exchange never receives your private keys, seed phrase, or wallet credentials. Signing happens in your wallet; we only receive the transaction you asked us to prepare.

4. Controlling cookies

You can block or delete cookies in your browser settings at any time. Blocking cookies entirely only affects the moment of a paid trade's settlement; everything else on the site — browsing, quotes, and free trades — works without cookies.
