Does TSM / SPY match its issuer's published contract?

The pool's quote contract matches Robinhood's registry entry for TSM.

Verified means the observed quote-token contract matches an issuer-published registry entry on Robinhood Chain. Only the quote-side contract is checked.

This does not prove backing, custody, reserves, price, safety, solvency, or endorsement.
