Bridge Fee is too Expensive

I think the fee is too high because it is charged to the token that wants to be wrapped or unwrapped. Why doesn’t the fee use stacks?

For example, if I want a bridge of 999,999 USDT I need a fee of 4,999 USDT. This fee is quite large. If ALEX Lab implements a low fee for bridging, I feel that more people will use the ALEX Bridge platform.
