AMAT: balanceOf() is 1.000044656x away from share-equivalents

subject AMAT (0x36046893810a7E7fCE501229d57dc3FC8c8716d0) · methodology assay-rh-v0.2.0 · detected 2026-09-21T20:58:28.000Z

AMAT reports uiMultiplier() = 1000044656302636618 (1.000044656). 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 0.0045% (the true count is 1.0000x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

0.45 bps · 0.0045%

totalSupply raw 254.2737 tokens vs 254.2850 share-equivalents (delta 0.0114). Presenting the raw balance as a share count understates by 0.0045%; equivalently the true count is 1.0000x the raw.

Reproduce this yourself:

cast call 0x36046893810a7E7fCE501229d57dc3FC8c8716d0 "uiMultiplier()" \
  --block 69102229 \
  --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.
