Deposit funds from Ethereum Layer 1 to your Loopring Layer 2 in-app
A. Open the Loopring Smart Wallet app
With the app open:
Tap Loopring L2
Tap Receive
Tap From my L1 account
B. Set the deposit token and amount
While on the L1 Send screen:
Enter the token to deposit to your L2 account. Tap to select from a list of available tokens in your L1 balance.
Enter the amount of tokens to deposit to your L2 account. To deposit all of the tokens, simply tap All.
Confirm the details one more time. When you are ready to proceed, tap Next.
C. Submit a Token Approval (tokenโs first-time only)
You will only see this next screen if it is the first time depositing or withdrawing the token from your L1. If it appears, tap Confirm to submit a Token Approval transaction.
The Token Approval requires a gas fee; this fee will be shown on the screen
After submitting, you can check the status of the Token Approval by opening your Transaction History, tapping the transaction, and then tapping the TxID link. Once the process is complete, the Etherscan status will show as Success. You can then restart the steps to deposit.
D. Verify the gas fee payment preferences
The Loopring Wallet will use your token order located in Settings > Fee Preference when determining the token used for paying fees. You have the option to change the token on the Confirmation screen.
Ensure you have more than enough tokens in your balance to pay the fee or the remainder needed may be taken from the other layerโs balance.
Tap Change
If needed, change the Layer the token will be paid from
Tap the token used to pay the gas fee
If needed, change the transaction speed (this will also change the amount needed for the gas fee)
Slower is usually cheaper, while faster is usually more expensive
