The control finding
Apyx and its custody partners manage off-chain preferred-share collateral; only whitelisted participants can mint or redeem, while other holders depend on secondary liquidity.
- Backing
- Off-chain preferred-share instruments including disclosed STRC and SATA exposures, with liquidity buffers.
- Holder’s position
- apxUSD is a platform token supported by securities held through custody structures, not a direct shareholding.
- Redemption or exit
- Only whitelisted participants mint or redeem directly; other holders rely on secondary liquidity.
Dependencies an advisor should record
- Apyx operators
- MPC custody partners
- Preferred-share issuers and market liquidity
- Whitelisted counterparty access
Material incident check
- No material control, reserve, or redemption incident was identified in the reviewed sources.
Why this distinction matters
Record Apyx operators, MPC custodians, and whitelisted issuance partners as the controlling party, verify direct-redemption eligibility, and do not treat an on-chain balance as eliminating reserve, custody, contract, or legal dependencies.
A named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions. That finding can coexist with a sound reserve, useful product, or appropriate client role. The grade prevents the on-chain wrapper from being mistaken for the absence of an administrator.

Legend — Sovereign: no issuer-level freeze exists · Crypto-backed: governance and collateral, no conventional blocklist · Hybrid control: on-chain mechanisms coexist with compellable parties · Issuer-controlled: a named administrator controls issuance, transfers, or restrictions. How grading works.
