AAPL: balanceOf() is 1.000566080x away from share-equivalents

subject AAPL (0xaF3D76f1834A1d425780943C99Ea8A608f8a93f9) · methodology assay-rh-v0.2.0 · detected 2026-09-21T21:00:41.000Z

AAPL reports uiMultiplier() = 1000566080061092436 (1.000566080). Under ERC-8056 a corporate action moves this multiplier rather than balances, so balanceOf() returns tokens, not share-equivalents. Share-equivalents = balance * uiMultiplier() / 1e18. Any surface presenting balanceOf() as a share count understates it by 0.0566% (the true count is 1.0006x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

5.66 bps · 0.0566%

totalSupply raw 15679.5673 tokens vs 15688.4432 share-equivalents (delta 8.8759). Presenting the raw balance as a share count understates by 0.0566%; equivalently the true count is 1.0006x the raw.

Reproduce this yourself:

Note: the public RPC prunes state within roughly 1k–10k blocks, so an older block may no longer be served. That makes a citation unchecked here, not disproven — ASSAY reports those two cases separately and never publishes a finding whose citation contradicts chain state.
