I would like to create a service like this, but do I earn from fee ? Otherwise, the maintenance costs for a free product would not be able to maintain these costs

[christophercumpio]

Thank you..Does it work with a trusted wallet as well or does it work with Metamask only?

I am glad to have joined, though I started late. I have to start from pt1. There are some crypto currency I bought and some airdrops I got but I can't sell it because the liquidity wasn't added, it keeps saying " insufficient liquidity" I need to learn this to enable me to understand the ethics and methodology in which they operate. Pls I am going to write you on twitter. Thank you for this.
