How to change the default currency on Trust Wallet? (App Preferences)

Accessing App Preferences in Trust Wallet

1. Open the Trust Wallet application on your mobile device.

2. Tap the profile icon located in the top-right corner of the home screen.

3. Scroll down and select Settings from the menu.

4. Locate and tap Preferences — this section governs display, language, and currency behavior.

5. Ensure you are not in a wallet-specific view; global currency settings apply only at the app level, not per wallet.

Navigating the Currency Display Option

1. Within Preferences, find the entry labeled Default Currency.

2. Tap on it to open a searchable list of over 100 supported fiat currencies.

3. Use the search bar to type abbreviations like USD, EUR, JPY, or BTC — yes, Bitcoin is listed as a display option despite being a cryptocurrency.

4. Select your preferred currency — the change applies instantly across portfolio balances, transaction histories, and token valuations.

5. No restart or confirmation prompt is required; values refresh automatically upon selection.

Understanding Currency Conversion Mechanics

1. Trust Wallet pulls real-time exchange rates from CoinGecko’s API for all fiat and major crypto pairs.

2. The selected default currency affects how token values appear in the main wallet view and asset detail screens.

3. Historical transaction values remain fixed in the currency used at the time of the transaction — no retroactive conversion occurs.

4. Staking rewards, gas fee estimates, and swap quotes dynamically reflect the chosen default currency in real time.

5. Exchange rate updates occur every 60 seconds when the app is active and connected to the internet.

Limitations and Known Behaviors

1. Cryptocurrency balances always retain their native unit (e.g., ETH remains ETH, SOL remains SOL) regardless of default currency setting.

2. Multi-chain wallets do not support chain-specific currency preferences — the setting is unified across Ethereum, BSC, Polygon, Solana, and others.

3. Fiat currency symbols may not render correctly on older Android versions due to font rendering constraints.

4. If the app fails to load exchange rates, balances display as “—” until connectivity resumes and the API responds.

5. Changing the default currency does not affect blockchain transaction fees — those are always denominated in the native chain token.

Frequently Asked Questions

Q: Does changing the default currency affect how I send or receive tokens?A: No. Sending and receiving operations use native token units exclusively. The default currency only alters value representation in the UI.

Q: Can I set different currencies for different wallets within the same Trust Wallet app?A: No. Trust Wallet enforces a single global default currency setting across all imported and created wallets.

Q: Why does my BTC balance show as $0.00 after switching to BTC as the default currency?A: This occurs because BTC-to-BTC conversion is undefined in the pricing API. Trust Wallet disables fiat-style valuation when BTC is selected as the default, reverting to raw BTC units without USD equivalents.

Q: Is the default currency setting synced across devices via backup?A: No. Preferences including default currency are stored locally on each device and are not included in the 12-word seed phrase backup or cloud sync mechanisms.
