Advisor notes
Controlling party: Ethena Labs and privileged token-contract administrator. Check whether the client can redeem directly with the issuer. Holding the token on chain leaves every reserve, custody, contract, and legal dependency in place.
A named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions. This grade can sit beside a sound reserve, a useful product, or a fitting role in a client account. It records who can act on the token and passes no judgment on the product.

Legend: No freeze key: no issuer or administrator can freeze an address at this layer · Governed, no freeze: on-chain collateral and governance set the terms, but no issuer blocklist exists · Mixed control: on-chain mechanisms sit beside custodians, real-world assets, a central transaction orderer, or other parties a court or regulator can compel · Issuer can freeze: a named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions.
