CoinDesk now refuses every request without an API key, so mainnet showed no
USD prices. On mainnet the wallet now reads latestRoundData() from Chainlink's
USD price feeds through the configured RPC endpoint. ETH and the held or
tracked tokens with a feed are read as one batched request, at most every 5
minutes. src/shared/tokenList.js lists the feeds of 53 bundled tokens, keyed by
contract address, and the ETH/USD feed. A reading older than its feed's
heartbeat plus 30 minutes, or not positive, is no price. A failed read leaves
no price and is logged. getPrice() takes a contract address instead of a
symbol. The CoinDesk request is removed.
Model: opus-5-5
parseInt(decimals || "18") ran before writing stored tokenBalances[].decimals, so an explorer reporting no decimals produced a fabricated 18 indistinguishable from a real one at read time. That defeated the resolve-or-refuse guarantees of #306 and #340: their refusal paths were intact but never fired, because the guess was laundered upstream of them.
An absent scale is now stored as unknown, and a holding whose scale nothing knows carries a null balance -- unknown, never zero -- with six reader sites saying so rather than printing 0.0000. The Send screen resolves the display scale rather than reading the stored one, so a bundled token whose explorer row omits decimals still sends; when the scale cannot be resolved the stored quantity is withdrawn too, so the user is told the balance is unknown rather than only that the fee failed.
Existing fabricated 18s cannot be told apart retroactively and are replaced wholesale on the next balance refresh. An explorer-sourced scale stays trusted -- only fabrication is removed; the reasoning is recorded on the issue.
