UNH: balanceOf() is 1.004241501x away from share-equivalents

subject UNH (0xcF364ea52787e289De6F32077834056E3E70D6A8) · methodology assay-rh-v0.2.0 · detected 2026-09-21T20:54:01.000Z

UNH reports uiMultiplier() = 1004241501039702113 (1.004241501). 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 0.4224% (the true count is 1.0042x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

42.42 bps · 0.4224%

totalSupply raw 97.0095 tokens vs 97.4210 share-equivalents (delta 0.4115). Presenting the raw balance as a share count understates by 0.4224%; equivalently the true count is 1.0042x the raw.

Reproduce this yourself:

cast call 0xcF364ea52787e289De6F32077834056E3E70D6A8 "uiMultiplier()" \
  --block 69099548 \
  --rpc-url https://rpc.mainnet.chain.robinhood.com

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.
