 For local simulation to interact with a chain, you must specify RPC endpoints for the chains you interact with in the `project.yaml` file. This is required for submitting transactions and reading blockchain state.
 
-Note: Only eth sepolia (chain selector `16015286601757825753`) is supported in local simulation
+Note: Only eth sepolia (chain name `ethereum-testnet-sepolia`) is supported in local simulation

 For a quick start, you can also use the pre-deployed contract addresses on Ethereum Sepolia—no action required on your part if you're just trying things out.
 
 For completeness, the Solidity source code for these contracts is located under projectRoot/contracts/evm/src.
