If you encounter a low tBnB balance on the Testnet, I present you the following way to fix this, resp. top-up your balance.
Option 1:
Step 1:
Visit this BnB Faucet: https://www.bnbchain.org/en/testnet-faucet
Enter the respective wallet and click “Send 0.3 BNB”.
Ensure you have at least 0.002 BNB on your BnB Chain main wallet as otherwise, you are going to receive the below error
(Why: It is to minimize such requests to ’empty’ wallets that have the sole purpose to collect tBnB)

Error message

Step 2:
You should have received the below receipt after successful transaction.

Step 3:
You will notice that your balance remains unchanged. This is because the BNB mentioned above is on the wrong chain. Currently, it resides on the ‘BNB Smart Chain Testnet,’ whereas Valhalla operates on the ‘opBNB Testnet,’ which is a different chain. Therefore, bridging is required.

Step 4
Visit this opBNB Bridge: https://opbnb-testnet-bridge.bnbchain.org/deposit and connect your wallet

Step 5:
Approve that BNB Smart Chain Testnet is added as a network

Step 6:
Approve that the network is switched to BNB Smart Chain Testnet so that the bridging can take place

Step 7:
Add the maximum amount possible, ensuring there are sufficient funds to cover gas fees, before clicking “Deposit.”
–> ‘Total Amount’ (here 0.29854165 BNB) must not surpass ‘Balance’ (here 0.3 BNB)

Step 8:
Confirm the transaction

Step 9:
Visit Valhalla | My Account (or www.valhalla.game and follow the below steps)

Step 10:
Add the maximum possible amount that still allows to cover the gas fee and confirm

Step 11:
Wait 30 seconds and refresh the site (F5) – Congratulations! You have successfully topped-up your tBnB balance and got now rid of the low BnB message š„
