The Clarity App has integrated the "Add Liquidity" functionality of Uniswap, also referred as "Pool". Clicking on "Add Liquidity" 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://coinmarketcap.com/headlines/news/uniswap-liquidity-pool/
The concept of pools on Uniswap is explained in detail here: https://uniswap.org/docs/v2/core-concepts/pools/
Please note that DeFinity cannot accept any responsibility for the risks that may occur when using the pool functionality. DeFinity only includes the function "as is".
