 This example demonstrates how to create a `Token` instance for DAI on the Ethereum Mainnet using the `token!` macro.
 
 It then prints the token's address and checks if it's a native token (which it isn't, so it prints false).

 Remember to replace "0x6B175474E89094C44Da98b954EedeAC495271d0F" with the actual address of the DAI token you're working
 with, and adjust the CHAIN_ID if you're working on a different network (e.g., a testnet).
