Ok, correct me please. There's actually only ONE "smart contract" in the entire Solana chain called SPL-Token Program or just Token Program in short, is that right? So tokens are not created or stay inside smart contracts.
Could you explain, if I want to transfer 1 USDC to another wallet, which address should I use? I don't understand what "interact with a specific token" means. I thought tokens are all controlled by a token program (like USDC token is controlled by USDC token program) so our code just sends instructions to token program to send 1 USDC to someone. But here, do I talk to the USDC token itself?
Why do you need an address for token (Token Mint) when you have address for Program (smart contract). Do you have an example of a Token Mint? I don't agree with what you said about Token Program ID and Token Program. AFAIK, Token Program is a MOTHER program that takes care of other programs. Please view this - nimb.ws/VreUTd. Otherwise, we won't have the constant TOKEN_PROGRAM_ID.
