 ## How do network fees on Astar zkEVM work?
 In Astar zkEVM the gas fee is calculated by applying a fixed factor over L1 gas fee. That price factor is a fixed value and doesn't change often and it's value is based the rollup's cost to publish tx to L1. To Simply put, gas prices in L2 will linearly follow gas prices in L1.
 
-$$ L2_{gas\_fee} = L1_{gas\_fee} * Factor $$
+$$
+L2_{gas\_fee} = L1_{gas\_fee} * Factor
+$$
 
 The L1 fee will vary depending on the amount of transactions on the L1. If the timing of your transaction is flexible, you can save costs by submitting transactions during periods of lower gas on the L1 (for example, over the weekend)

 ## What is Astar zkEVM?
 
 Astar zkEVM is an Ethereum Layer-2 scaling solution leveraging Polygon's Chain Development Kit and cutting edge zero-knowledge cryptography to enable off-chain transaction execution, with finality and security guarantees provided by Ethereum. In coordination with our key partners, Astar zkEVM is well-positioned to take advantage of the extensive developer base and well-established toolset existing in the Ethereum ecosystem, and boasts the following key features:

+Blockchain oracles are third-party services or agents that provide smart contracts with external information. They serve as bridges between blockchains and the external world. Because blockchains cannot access external data (outside of their network) due to their secure and deterministic nature, oracles are used to fetch, verify, and relay real-world data to smart contracts in a way that's trustworthy.

 It's crucial that developers can thoroughly test the network for a developing blockchain technology like **Astar zkEVM** without putting users or themselves at unnecessary risk. Developers should be able to test their smart contracts, experiment with new code, and play around with the network on their local machines.
