Charged for funds not moved
There can be occurrences after a transaction is submitted where network congestion spikes, causing the submitted gas to not be enough to complete your transaction. In these instances, the submitted gas fee is consumed and the coins remain in the originating wallet. If gas price is volatile, you can manually set the gas limit to accommodate for higher gas allowance. Otherwise, you can wait until network utilization is low to ensure your transactions completes successfully with lower fees. The error below (Out of gas) will be displayed on Etherscan for the submitted transaction:
For further information on gas and fees see the following articles:
When moving funds out of L1, please ensure you check the gas fee. The gas fee may be more than the actual balance being moved. The gas fee is estimated and included in the overall transaction. If the gas fee is more than the actual balance being moved from L1 to L2, you will have the scenario where no funds are moved, and you will be charged a gas fee which is taken from your L2 balance (if your fee preference has been set to enable fees being paid from L2). Additionally, if you are moving funds from L1 to L2 within the Loopring Smart Wallet you’ll pay an approval fee the first time per token being moved. Example: You want to move LRC from L1 to L2 in your Loopring Smart Wallet. If you’ve never done this before, then you pay an approval fee to allow LRC and then a gas fee for the transaction because it’s on L1. The next time you need to send L1 to L2 you don’t pay an approval fee, only the gas fee.
