UPS: balanceOf() is 1.002208725x away from share-equivalents

subject UPS (0xf23250dac154D05Bb671CB0d0eBEf3c635c79CE2) · methodology assay-rh-v0.2.0 · detected 2026-09-21T20:51:05.000Z

UPS reports uiMultiplier() = 1002208724969205741 (1.002208725). 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 0.2204% (the true count is 1.0022x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

22.09 bps · 0.2204%

totalSupply raw 2964.7409 tokens vs 2971.2892 share-equivalents (delta 6.5483). Presenting the raw balance as a share count understates by 0.2204%; equivalently the true count is 1.0022x the raw.

Reproduce this yourself:

cast call 0xf23250dac154D05Bb671CB0d0eBEf3c635c79CE2 "uiMultiplier()" \
  --block 69097785 \
  --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.
