Verified · Ondo SNDK

Does SNDKon / USDC match its issuer's published contract?

The pool's quote contract matches Ondo's registry entry for SNDK.

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

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