SOXX: balanceOf() is 1.000450838x away from share-equivalents

subject SOXX (0x75742c18BC1f1C5c5f448f4C9D9C6F66dafAAa38) · methodology assay-rh-v0.2.0 · detected 2026-09-21T21:03:57.000Z

SOXX reports uiMultiplier() = 1000450838210425960 (1.000450838). 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 0.0451% (the true count is 1.0005x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

4.51 bps · 0.0451%

totalSupply raw 223.8669 tokens vs 223.9678 share-equivalents (delta 0.1009). Presenting the raw balance as a share count understates by 0.0451%; equivalently the true count is 1.0005x the raw.

Reproduce this yourself:

cast call 0x75742c18BC1f1C5c5f448f4C9D9C6F66dafAAa38 "uiMultiplier()" \
  --block 69105479 \
  --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.
