# FAQ

## Why sometime it costs a little high fee?

We operate on the L2 network, but L2's transaction fees are also affected by Ethereum’s gas fees because L2 networks need to submit data batch to Ethereum to maks everything safe. During the peak period of Ethereum, the gas fee of Ethereum increased significantly, so the transaction fee of L2 also increased accordingly.

Don't worry, your fund must be safe. Just go to our [discord](https://discord.gg/bgKn2ZU6cH), open a ticket, ask for help. OKOK team will reach you as soon as possible.
