Some quick first thoughts:
1. I'm required to provide a refund address for all three BTC, USDT, and XMR. Sometimes I just want to trade BTC<>USDT and don't have a XMR wallet... or want to trade XMR<>USDT and I don't have a BTC wallet.
2. The USDT network isn't specified on the refund addresses page. Is it ETH? Polygon? BSC? I saw later that you use Polygon, probably better to specify that on the refund addresses page.
3. After providing the refund addresses, it says I can deposit but there is no button to go on (or automatic redirect). Add a link/button next to "you can deposit" that takes the user to the deposit page.
1. Yes, you don't have to provide every refund address. You can provide a refund address when you need to trade a specific pair or before generating a deposit address.
2. Yes, right now I haven't set up the USDT testnet. You are correct I'm going to use Polygon USDT. Thanks for the suggestion; I will make it easier to understand which network the refund address should be updated for.
3. Okay, noted. I will include that in the update.
Thanks for checking it out it means a lot. Have a great day.
