+## Additional Costs
+
+There are additional costs associated with using Lit Protocol's services that are not covered by the network usage payments. These include:
+
+- **Gas on Lit Chain** - Lit Chain is the database for Lit network.  When you make a transaction on Lit Chain, you will need to pay for the gas used by the transaction.  Examples of operations that would require a transaction on Lit Chain are things like changing PKP Permissions, transferring PKPs, and launching smart contracts on Lit Chain.  Lit Chain gas is priced in $LITKEY tokens and the gas price is very low compared to other chains.
+- ** PKP Minting** - When you mint a new PKP, you will need to pay a specific fee for the minting operation.  Check out the [Current Prices page](/learning-lit/pricing/current-prices) to see the price right now.
