INTU: reading balanceOf() as shares understates by 0.3217% (multiplier 1.003226934x)
Who carries the exposure
Any integrator that presents INTU 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.
INTU reports uiMultiplier() = 1003226934400018698 (1.003226934), 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 0.3217% (the true count is 1.0032x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.
Impact
0.3217%
totalSupply raw 32.5169 tokens vs 32.6218 share-equivalents (delta 0.1049). Presenting the raw balance as a share count understates by 0.3217%; equivalently the true count is 1.0032x the raw.

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.
