For users tracking their net worth, the accuracy of the portfolio value display is paramount. This test rigorously checks the fiat currency conversion and total portfolio calculation within the MetaMask Android app. The test requires a wallet with a known quantity of multiple assets: ETH and several ERC-20 tokens. The user must ensure the app is set to their preferred fiat currency (e.g., USD, EUR) in the settings. The tester then manually calculates the expected total value by taking the amount of each asset and multiplying it by the current market price (obtained from a reliable external source like CoinGecko or CoinMarketCap). The total sum should be compared to the portfolio value displayed at the top of the MetaMask asset screen. The values should be reasonably close, accounting for slight delays in price feed updates and the volatility of the crypto markets. A significant discrepancy indicates a problem with the price oracle integration. This test validates the reliability of the financial data presented to the user. Information on the price feed providers can sometimes be found at metamask.
