Guard · Ethereum

Allow

This pool includes Ondo's published MRVL contract on Ethereum.

The issuer can change token rules.

Source verified.

QED is read-only by design: it never holds keys, never submits transactions, and never recommends; that is why anyone can integrate it.

This point-in-time review does not prove backing, custody, reserves, solvency, safety, price, liquidity, or endorsement. Re-check before relying on changed chain or issuer facts.

How to read the verdict: Allow means completed checks found no contradiction or active restriction; Deny means QED observed a contradiction or active restriction; Unknown means a check was incomplete or could not be verified. These are not safety ratings.
