VST: balanceOf() is 1.001114739x away from share-equivalents

subject VST (0x561e2a49212b7cCF47f2744Ccb83e200722fADBc) · methodology assay-rh-v0.2.0 · detected 2026-09-21T20:52:09.000Z

VST reports uiMultiplier() = 1001114738710796417 (1.001114739). 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 0.1113% (the true count is 1.0011x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

11.15 bps · 0.1113%

totalSupply raw 105.2955 tokens vs 105.4129 share-equivalents (delta 0.1174). Presenting the raw balance as a share count understates by 0.1113%; equivalently the true count is 1.0011x the raw.

Reproduce this yourself:

cast call 0x561e2a49212b7cCF47f2744Ccb83e200722fADBc "uiMultiplier()" \
  --block 69098438 \
  --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.
