APK releases on GitHub, Accrescent, and F-Droid use the same key. They can easily be verified using [apksigner](https://developer.android.com/tools/apksigner#options-verify) or [AppVerifier](https://github.com/soupslurpr/AppVerifier).
See below for Cake Wallet's SHA-256 signing certificate hash:
3. For strings where there is a variable, denoted by a $ symbol and braces, such as ${status}, the string in braces should not be translated. For example, when editing line 106:
"time" : "${minutes}m ${seconds}s"
The only parts to be translated, if needed, are the values m and s after the variables.
4. Add the language to `lib/entities/language_service.dart` under both `supportedLocales` and `localeCountryCode`. Use the name of the language in the local language and in English in parentheses after for `supportedLocales`. Use the [ISO 3166-1 alpha-3 code](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3) for `localeCountryCode`. You must choose one country, so choose the country with the most native speakers of this language or is otherwise best associated with this language.
5. Add a relevant flag to `assets/images/flags/XXXX.png`, replacing XXXX with the 3 letters localeCountryCode. The image must be 42x26 pixels with 3 pixels of transparent margin on all 4 sides. You can resize the flag with [paint.net](https://www.getpaint.net/) to 36x20 pixels, expand the canvas to 42x26 pixels with the flag anchored in the middle, and then manually delete the 3 pixels on each side to make it transparent. Or you can use another program like Photoshop.
1. Check with [Cake Wallet support](https://guides.cakewallet.com) to see if the desired new fiat currency is available through our fiat API. Not all fiat currencies are.
2. If the currency is associated strongly with a specific issuing country, map the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) currency code with the applicable [ISO 3166-1 alpha-3 code](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3) in `lib/entities/fiat_currency.dart`. If the currency is used in a whole region or organization, then map with a reasonable interpretation of this (eg: eur countryCode for EUR symbol).
3. Add the raw mapping underneath in `lib/entities/fiat_currency.dart` following the same format as the others.
4. Add a flag of the issuing country or organization to `assets/images/flags/XXXX.png`, replacing XXXX with the ISO 3166-1 alpha-3 code used above (eg: `usa.png`, `eur.png`). Do not add this if the flag with the same name already exists. The image must be 42x26 pixels with a 3 pixels of transparent margin on all 4 sides.
