The commented out code should be removed. It's generally not a good practice to leave large blocks of commented out code in the codebase. If this code is not being used, it should be removed. If it's needed for future reference, it should be documented elsewhere (e.g., in a design document or a separate branch).

The NewUser function is creating HTTP and WebSocket clients by appending the user ID to the server address. This could potentially expose the user ID in logs or network monitoring tools, which might be a security concern. Consider using a more secure method to authenticate the user with the server, such as using HTTP headers or secure cookies.

The RegisterAccounts function is registering each wallet in the user's wallet list. However, it stops and returns an error if it fails to register any of the wallets. This could potentially leave some wallets unregistered. Consider continuing to attempt to register the remaining wallets even if one fails, and return a list of the wallets that failed to register.

for _, w := range u.Wallets {
balance, err := u.HTTPClient.BalanceAt(context.Background(), w.Address(), nil)
if err != nil {
return err
}
fmt.Println("Balance for account ", w.Address().Hex(), " - ", balance.String())
}
return nil
}

As per the previous comment, the PrintUserAccountsBalances function is directly printing the balance of each account to the console. This might not be desirable in a production environment. Consider returning the balances to the caller instead, so they can decide how to handle it.

-		fmt.Println("Balance for account ", w.Address().Hex(), " - ", balance.String())
+		balances = append(balances, balance.String())
