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.

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

Rule-change signals

  • eip1967_implementation: EIP-1967 implementation slot points to 0x267e11bB559F5D392e498cdD0e2342057031A2Cf; upgrade permissions were not established by this read.
  • eip1967_admin: EIP-1967 admin slot contains 0x5244A3D8E6534D253c11B9459a4c4C6d3B2361DD.

Implementation source: Match; proxy: Match. Observed at .

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