Why USDC gives no warning
Tether freezes through a multisig, so its first signature is public and can be seen before the
freeze. Circle does not: a single blacklister address calls blacklist(address) on the
USDC contract and the wallet is frozen in that one transaction. The only moment it is visible
beforehand is the few seconds it waits to be mined.
We say this plainly because it limits what any monitor can promise: for USDC, a check tells you the state now; no service can reliably warn you in advance.
