 ## Test
 
-**Note:** Our test code may not directly support Apple Silicon (M1/M2) chips. However, we've provided a Docker-based solution for local testing on M1/M2 Macs. Please refer to the [Local Testing on M1/M2 Mac](../README.md#local-testing-on-m1m2-mac) section in the main README for details. After preparing the environment, you can then proceed with the testing.

 - Gas Oracle (<a href="./cmd/gas_oracle/">gas_oracle</a>): monitors the L1 and L2 gas price and sends transactions to update the gas price oracle contracts on L1 and L2.
