Who carries the exposure

Any integrator that presents QQQ balanceOf() as a share count. The contract itself is behaving as ERC-8056 specifies and is not at fault.
The contract named above is what was READ. Naming it is not an accusation against it: a Stock Token that moves uiMultiplier() is doing what ERC-8056 specifies.

QQQ reports uiMultiplier() = 1000700791241405425 (1.000700791), which is CORRECT AND SPEC-COMPLIANT behaviour under ERC-8056 — this finding is not a defect in the token contract. It records the exposure carried by a caller that reads balanceOf() as shares. Under ERC-8056 a corporate action moves the multiplier rather than balances, so balanceOf() returns tokens and share-equivalents = balance * uiMultiplier() / 1e18. A surface presenting the raw balance as a share count understates it by 0.0700% (the true count is 1.0007x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

0.07% · how far a raw balanceOf() read as shares understates the true share count, as a share of the true count
totalSupply raw 6006.4439 tokens vs 6010.6531 share-equivalents (delta 4.2092). Presenting the raw balance as a share count understates by 0.0700%; equivalently the true count is 1.0007x the raw.

Right of reply

No reply has been received for this finding. Anyone named here can have a response published verbatim and unedited alongside it. A finding shown to be wrong is corrected by changing the rule that produced it, with the notice recorded in the repository. Open a right-of-reply issue or see docs/RIGHT-OF-REPLY.md. Pre-publication notice is deliberately not claimed: the sweep publishes on a timer and for most findings the subject is a contract, not a person to notify.
