FEEDBACK - Slow Bridge and Expensive Fee for Bridge

improve your network. i using the bridge many times but got slow execute for transaction and every bridge need fee very expensive.

stack to sepolia: need fee arround 10$ and 10-30 minutes to execute tx
sepolia to stack: need fee arround 7,5$ and arround 1 hours to execute tx
