COST: balanceOf() is 1.000612040x away from share-equivalents

subject COST (0x4EA005168D7F09a7A0Ba9D1DEf21a479950E44C2) · methodology assay-rh-v0.2.0 · detected 2026-09-21T21:03:16.000Z

COST reports uiMultiplier() = 1000612040296259656 (1.000612040). 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 0.0612% (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

6.12 bps · 0.0612%

totalSupply raw 1520.7802 tokens vs 1521.7110 share-equivalents (delta 0.9308). Presenting the raw balance as a share count understates by 0.0612%; equivalently the true count is 1.0006x the raw.

Reproduce this yourself:

cast call 0x4EA005168D7F09a7A0Ba9D1DEf21a479950E44C2 "uiMultiplier()" \
  --block 69105078 \
  --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.
