* **CurrencySingle and CurrencyPlural**: Tags used to display currency amounts. For example, `1€` is shown as `1euro`, and `2€` as `2euros`.
* **decimalFormat**: Specifies the format of the amount based on DecimalFormat patterns.
* **payTax**: The tax rate applied to transactions. A `10%` tax rate is represented as `0.1`. Setting `1.0` results in a `100%` tax.
* **bankEnabled**: Enables the bank feature in Vault's Economy class for developers.
* **taxOnlyPay**: If enabled, `payTax` applies only to the pay command; otherwise, it applies to both pay and balance commands.
* **saveTransaction**: When enabled, transactions are recorded for every money movement.
* **transactionTTL**: The time, in seconds, after which a transaction is removed from the system to keep the transaction database manageable.
* **executorThreads**: The number of threads allocated to make balance modification (every account has a dedicated thread based on it's ID to keep thread-safety over balances)
