How to read this verdict

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.

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.

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

Technical details

Transfer-blocking signals

  • pausable: isPaused() is implemented; currently not paused; pauser() returned 0x8768cDA7A463DAe1baA6b2500EFB025ebd7FFC50; owner() returned 0x49754062E35f7591B93cc4F9915965be89643a65.
  • pauser: pauser() returned 0x8768cDA7A463DAe1baA6b2500EFB025ebd7FFC50; the getter alone does not establish its permissions.
  • sanctions_list: sanctionsList() returned 0x40C57923924B5c5c5455c48D93317139ADDaC8fb; transfer effects were not inferred from the getter alone.

Rule-change signals

  • eip1967_implementation: EIP-1967 implementation slot points to 0x65c40D624Af3B18C109fBF87B7DEff34CdC5f19b; upgrade permissions were not established by this read.
  • eip1967_admin: EIP-1967 admin slot contains 0x696C685a02A1Fc6E2AaCbe26CD6695F4f4a6a085.
  • owner_getter: owner() returned 0x49754062E35f7591B93cc4F9915965be89643a65; the getter alone does not establish which actions the role can take.

Implementation source: Exact match; proxy: No match. Observed at .

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