 ## Step 2: Deploy Your Contract on Rootstock Network
 Run the following command, replacing `https://public-node.testnet.rsk.co` with either `rskTestnet` or `rskMainnet` rpc url if you have, depending on your desired deployment environment:

 - [EIP-1559](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md) is not supported or not activated on the Rootstock RPC url
+- To avoid Foundry's compatibility issues, we are using the `--evm-version london` flag.
 - The `--legacy` flag is passed to use legacy transactions instead of `EIP-1559`.
 - You can remove the `--broadcast` flag if you wan to simulate the transaction without broadcasting it.
