THORChain has no KYC because it has nowhere to put one. There is no account: you send an asset from your wallet to a vault address with a memo, and the network delivers the output to the address in the memo. No ID, no selfie, no email. Interfaces built on it may screen addresses or ask nothing at all, and a wallet with THORChain built in typically asks nothing. For someone who wants to move between native Bitcoin, Ethereum and Monero without handing a passport to anyone, that is the entire appeal, and no licensed venue can match it.
It is equally honest to say what "no KYC" does not do. It does not remove U.S. tax obligations; every swap is a disposal of one asset and an acquisition of another, and the chains involved are public and permanent. It does not remove sanctions obligations; THORChain was the rail of choice for the Lazarus Group after the Bybit hack, and a U.S. person is personally responsible for not transacting with a sanctioned party, whether or not a protocol checked. And it does not protect you from yourself: a wrong memo, a deposit to a retired vault, or a swap sent during a halt is the kind of mistake a Discord volunteer can explain but nobody can reverse.
Anytime Capital verifies identity once, before you pay, because U.S. money services businesses are required to. In exchange you get a licensed counterparty, a phone number, a record of your purchase for tax season, and coins delivered to a non-custodial wallet you control. For a THORChain user the two are complementary: verify once at the on-ramp, then swap from your own wallet wherever you like.
