This error usually happens when you’re trying to fund the wallet again instead of funding the MMF directly.

The message “You can’t fund your wallet with wallet” means:

You already have money in your wallet

But you’re clicking “Fund Wallet” instead of “Invest in MMF” / “Top-up MMF”

So the system thinks you’re trying to move money from wallet → wallet, which is not allowed.

✅ How to Fix It (Step-by-Step)

Try this:

Step 1

Go to MMF (Money Market Fund)

Step 2

Click:

Top up

Invest

Add funds (Depends on the app wording)

Step 3

Choose Wallet as payment method

Step 4

Enter amount → Confirm

Why It Worked Before

The first time:

You probably funded MMF directly

Not the wallet

Now:

You funded wallet first

Then mistakenly clicked fund wallet again

Another Possible Cause

Sometimes this also happens if:

App is lagging

Session expired

App needs update

Try:

Close app

Reopen

Try again
