 It will execute a simple check of transferring 10k wei from root key to root key and check if the transaction was successful.
 
+You can also enable pending nonce protection that will check if given key has any pending transactions. By default, we will wait 1 minute for all transactions to be mined. If any of them is still pending, we will panic. You can enable it with:
+```toml
+pending_nonce_protection_enabled = true
+pending_nonce_protection_timeout = "5m"
+```
+
 You can add more networks like this:
