Most currencies, whether cryptocurrency or fiat, have unique codes (e.g. "BTC", "LTC") across all wallets and exchanges.
We enforce this uniqueness in CryptFolio; we do not permit any of our tracked currencies to share a single currency code reference.
For exchanges that use differing internal codes (e.g. Kraken uses XXBT for Bitcoin BTC), CryptFolio maintains an internal code-to-currency mapping.
We also enforce that all codes must be lowercase. Special characters and/or UTF-8 codes (e.g. emoji) are fine.
In the case of a conflicting or different currency code, our policies are:
- An existing ISO4217 fiat code has priority over any cryptocurrency or token code. (e.g. ALL for Albanien lek vs ALL1 for Allion).
- For compatibility, BTC is used instead of XBT.
In the case of a conflicting code, we will instead use the code with a number affixed, in order of the currency being added to CryptFolio. For example, the Allion currency, which might otherwise have been defined as ALL, becomes ALL1.
If you find a currency or exchange pair that has been improperly defined, please let us know.
