Raw ERC-20 token balance (18 decimals).
Token balance as a float.
The quote used for valuation, or null if unavailable.
Share-equivalent units: balance * uiMultiplier / 1e18. After splits or
reinvested dividends this diverges from balanceTokens — trackers that
show raw balances as "shares" misstate positions.
ERC-8056 multiplier at read time (1e18-scaled).
USD value: balanceTokens * feedPrice. The feed price is already
multiplier-adjusted (price per TOKEN), so the multiplier must NOT be
applied again here — doing so double-counts corporate actions.
null when the token has no Chainlink feed or the feed was stale.
One holding inside a Portfolio.
