            The latest release is always accessible via our alias to the Cloudflare IPFS gateway at [app.uniswap.org](https://app.uniswap.org).

            You can also access the Uniswap Interface directly from an IPFS gateway.
            **BEWARE**: The Uniswap interface uses [`localStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) to remember your settings, such as which tokens you have imported.
            **You should always use an IPFS gateway that enforces origin separation**, or our alias to the latest release at [app.uniswap.org](https://app.uniswap.org).
            Your Uniswap settings are never remembered across different URLs.
