uSwap — Anything in, anything out sɣur u.software

uSwap puts the full uSwap app in a Firefox sidebar — swap any crypto for any crypto, or buy crypto with cash, in one click, without tabbing away from what you're doing.

What it adds on top of the web app:

• Fiat on-ramp payment capture. When you buy crypto with cash against uSwap's peer order book, the extension confirms your payment locally and hands the app a privacy-preserving, encrypted proof — so your crypto is released without ever sending your payment details to uSwap.

• Your data stays yours. Payment and session data is processed entirely inside the extension. Only an encrypted attestation ever leaves it, and it goes to the attestation service — never to uSwap. The extension stores no passwords and holds no API keys.

• Permission-minimal. Access to a payment provider (Cash App, Venmo, Wise, …) is requested only the first time you capture a payment there, and only for that provider — never at install.

uSwap is non-custodial: you hold your funds, and the engine just matches value in to value out.
