## Research summary

We reject USDT0 because the gap between its terms and its code adds risk without adding benefit. USDT0 is Tether's omnichain USDT, built on LayerZero's OFT standard and operated by Everdawn Labs Limited. Canonical USDT locks in an Ethereum adapter contract, and USDT0 mints 1:1 on the destination chain. It carries every USDT issuer and jurisdiction risk while adding an operator whose corporate relationship to Tether is assumed, not confirmed, plus the LayerZero DVN messaging-layer dependency that this registry separately rejects. Worse, USDT0's own Terms of Service describe no blacklist or freeze power, yet the deployed contract on Ink Chain includes functions to block addresses and destroy their held funds. This is a real control in the code that the user-facing terms do not disclose. Actual redemption rights depend on Tether's own "verified customer" gate, not a permissionless unlock, so a USDT0 holder gets worse redemption certainty than a direct USDT holder, not better.

## Observable review triggers

- Everdawn Labs' corporate relationship to Tether Limited is confirmed via a primary filing or Tether's own disclosure
- USDT0's Terms of Service are amended to explicitly disclose the blacklist and fund-destruction authority present in the deployed contract code
- A named chain's OFT deployment is audited independently of Tether and LayerZero's own claims, with the report published
- A proposed-size redemption from burned USDT0 to unlocked Ethereum USDT is demonstrated end to end without invoking Tether's verified-customer gate for an unaffiliated holder
- Any confirmed depeg, minting irregularity, or DVN-layer compromise affecting USDT0 specifically
