It seems some members didn’t get OP’s point. What he is looking for is a solution that allows him to send crypto even if he doesn’t have enough of the native coin to cover the fees. Like being able to send USDT (ERC-20) without having enough ETH to cover the gas.
Exactly, so I don't have to deal with gas when I'm just dealing with tokens
The news are the reason I asked for a wallet like this, I thought maybe there are some others that would have this feature and also would allow me to easily swap coins if I don't have any kind of funds on a certain chain.
Not a fan of metamask so I looked for an alternative with this feature.
I conclude that you are either looking for a webwallet because you do not realize that you can always use personal bitcoin wallets for online payments, or to conduct transactions in a variety of cryptocurrencies, not just Bitcoin.
You conclude wrong, I deal a lot with payments and most customers have moved away from BTC while my main funds are in BTC, dealing with 10-15 hot and cold wallets as I also need liquidity available would be impossible to manage and would only lead to a mistake sooner or later.
