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
