I have a Solana (#1) and USDT (#2) adddresses on the same account. I have some USDT coins in it. There's no USDC, though.
I've already sent some USDC to the #1 in testnet, from a faucet, but none of them has arrived.
I'm aware that in Solana, unlike Ethereum, for instance, an address for a token has to be generated first in order to activate it, and it has its own address. Right? But I haven't generated one for USDC.
Is this a reason that none of the USDC coins has arrived? How will I generate one if not in wallet app?
Is there the official online service of Solana that'll generate an associated address by the address of the main - SOL - one?
