The Clarity App has integrated the "Swap" functionality of Uniswap. Clicking on "Swap" from the dashboard takes you to the corresponding menu.
First, you have to establish a connection to your wallet where your DEFX tokens are stored. Once the connection is established, you can see the green status. The DEFX token is also preset.
You can find a detailed description of the procedure and the risks in this article: https://cryptopotato.com/how-to-use-uniswap-guide-and-must-read-risks-before-swapping/
The concept of a swap on Uniswap is explained in detail here: https://uniswap.org/docs/v2/core-concepts/swaps/
Please note that DeFinity cannot accept any responsibility for the risks that may occur when using the swap functionality. DeFinity only includes the function "as is".
