Hi,
I have a use case where I want to levy transaction fees of users to the admin. I was able to do this to the extent where only a single user is making a transaction, However, if there are multiple users making transactions at the same time then it fails due to the same nonce with the error “Returned error: replacement transaction underpriced.”
I was thinking of having multiple accounts to perform the user’s transactions by having a load balancer, but I am really concerned if that would be the right way of approaching the solution.
What approach would be an optimal one to resolve this issue?
