Ethereum Sepolia	Optimism Sepolia
Optimism Sepolia	Starknet Sepolia

Chain IDs

For reference, here are the chain IDs for the supported networks:

• Ethereum Mainnet: 1

• Ethereum Sepolia: 11155111

• Starknet Mainnet: STARKNET

• Starknet Sepolia: SN_SEPOLIA

• zkSync Era Sepolia: 300

• Optimism Sepolia: 11155420

When using the Herodotus API or interacting with smart contracts, make sure to use the correct chain IDs and contract addresses for your desired network.
