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.
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.
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.
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.
