In Aqua wallet you have support for Liquid Assets L-BTC and L-USDT, but you can also accept Lightning payments and stablecoins from other chains (ethereum, tron, binance, polygon, solana).
This is a bit closer to what I am searching for, not ideal but would solve the stable coin issue, although I would have loved support for USDC, I'm from Europe and I don't see a future for tether here.
Thanks for the clarification. I misunderstood your point. Obviously, you need a specific app or features to process large online payments. I want to emphasize that using webwallets for large online payments is highly risky, as you are vulnerable to all kinds of malicious attempts online.
Everything is risky, problem is accessibility, if I travel with a laptop full of wallets I'm also at risk for theft, I also risk every time I need to take the exchange from my wallet to an exchange to get those coins, the fees munching in the profit margin and so on. For an what they call investor that just gets his coins and stashes it away I would understand but I need liquidity on my available most of the time, I would love to deal only one one chain and only with one wallet but that would be just me going out of business.
