HPE: balanceOf() is 1.001716958x away from share-equivalents

subject HPE (0x59dd09d4900C2E4B5F75b7c0d4E6796fcc234Cb1) · methodology assay-rh-v0.2.0 · detected 2026-09-21T21:01:56.000Z

HPE reports uiMultiplier() = 1001716957939304938 (1.001716958). 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 0.1714% (the true count is 1.0017x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

17.17 bps · 0.1714%

totalSupply raw 603.8940 tokens vs 604.9308 share-equivalents (delta 1.0369). Presenting the raw balance as a share count understates by 0.1714%; equivalently the true count is 1.0017x the raw.

Reproduce this yourself:

cast call 0x59dd09d4900C2E4B5F75b7c0d4E6796fcc234Cb1 "uiMultiplier()" \
  --block 69104285 \
  --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.
