It’s done by providing liquidity into pools. Example for providing liquidity to PRV/USDC pool. You provide 10 PRV and the wallet automatically shows the equal value in USDC say it’s 15 USDC. You pay the transaction fee and confirm the transaction and you’ve added liquidity to the PRV/USDC pool.
If you want to list a new pair or add liquidity to the pair, which is not in Pool v2 yet, feel free to use the “Invest” section.
Btw thanks @CryptoDabber710 for explaining how “Invest” tap works
Thank you @elena and I’m happy to help in any way I’m able to.
