The portfolio view in Tonkeeper for Android, which shows the real-time fiat value of your cryptocurrency holdings, relies on a complex backend process. The wallet must constantly monitor the user’s on-chain balances and pair that data with live price feeds from various cryptocurrency exchanges. It aggregates this price data to provide an accurate and reliable valuation. The user can typically select their preferred fiat currency (USD, EUR, etc.). The application then calculates the total value by multiplying the amount of each asset by its current market price and summing them together. The reliability of this feature is critical; users make financial decisions based on this information. The team behind tonkeeper ensures that these price feeds are robust and have minimal latency, providing Android users with a trustworthy overview of their digital wealth in a currency they understand.
