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

The issuer can block transfers and 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.

Legend: these signals are controls QED observed on Ethereum; “no evidence observed” is not proof that no control exists.

Can seize tokens: no evidence observed.
Can block transfers: yes — pausable (currently not paused).
Can change token rules: yes — proxy implementation, proxy admin.

Technical details

Transfer-blocking signals

pausable: paused() is implemented; currently not paused (pauser not identified by this read).

eip1967_admin: EIP-1967 admin slot contains 0x5244A3D8E6534D253c11B9459a4c4C6d3B2361DD.

Implementation source: Match; proxy: Match. Observed at 10 Oct 2026, 03:53 UTC.

Absence of observed signals is not proof that no authority exists.

Wallet transfer restrictions

Check status: not requested

Reasons
