Is there a way to find all transfers of a specific token mint? Say I want to find all USDC transfers which happened on blockchain.
Can it be done efficiently?

For some function of "efficient", yes. You'd need to walk getSignaturesForAddress for the mint address. This answer is a good place to start.
EDIT: Given that the Transfer instruction doesn't reference the mint address, this solution would be incomplete. You'd probably have to do some awful graph walk to each account from each MintTo instruction on the mint

But
transferfunction doesn't acceptMintas an account, willgetSignaturesForAddressfind it anyway? Commented Aug 2, 2022 at 4:42 -
What you mean? According to docs, that method will return all transactions for a specific address, can be your address, an ATA, a mint or any address. You can use the result with getParsedTransactions to get information about each transaction. solana-labs.github.io/solana-web3.js/classes/… Commented Aug 2, 2022 at 6:19

2@RowanStone is right. the legacy
Transferinstruction makes no reference to the mint, instead just ensuring that the mints in the sender and recipient accounts match. these transactions won't be reflected on the mint's history. probably have to do something awful instead (edited) Commented Aug 2, 2022 at 6:30 -
@trent.sol, thank you, I should've been more specific, as
Transferinstruction was what prompted the question in the first place. Commented Aug 2, 2022 at 6:39
