# Currencies

Every Money carries a Currency — a readonly value with code, exponent, name, symbol, numericCode and iso. The registry is seeded with the bundled ISO 4217 list: 165 currencies from SIX List One (published 2026-09-17) with CLDR 47 English symbols.

```php
use RoundlyConsulting\Money\Currency;
use RoundlyConsulting\Money\Facades\Currencies;

Currencies::get('EUR')->exponent;          // 2
Currencies::find('XYZ');                   // null
Currencies::has('JPY');                    // true
Currencies::findByNumericCode(978);        // EUR
Currency::of('bhd')->numericCodeString();  // "048" — lookups trim and upper-case
Currency::of('JPY')->exponent;             // 0
Currency::of('EUR')->minorPerMajor();      // "100"
Currency::of('USD')->displaySymbol();      // "$"
Currency::of('CHF')->displaySymbol();      // "CHF" — the code when there is no symbol
Currencies::iso(); Currencies::custom(); Currencies::all();
```

## Custom currencies

Add points, credits or crypto with up to 18 decimals — in config:

```php
// config/money.php
'currencies' => [
    'iso' => true,
    'custom' => [
        'PTS' => ['exponent' => 0, 'name' => 'Loyalty points', 'symbol' => 'pts'],
        'BTC' => ['exponent' => 8, 'symbol' => '₿'],
        'ETH' => ['exponent' => 18, 'symbol' => 'Ξ'],
    ],
    'allowed' => ['EUR', 'USD', 'CZK'],   // currencies users may pick
],
```

…or in a service provider’s boot():

```php
// In a service provider's boot()
Currencies::register(Currency::custom('ETH', 18, 'Ether', 'Ξ'));
Currencies::register(Currency::custom('PTS', 0, 'Loyalty points', 'pts'));

Money::ofMajor('1.5', 'ETH')->minor();          // "1500000000000000000"
Money::ofMinor(1200, 'PTS')->format('en_US');   // "pts 1,200"
```

- ISO currencies can never be redefined — CurrencyAlreadyRegistered.
- Custom codes are 2–10 characters (a letter, then letters or digits), exponent 0..18, and must fit schema.currency\_length — raise it before migrating for codes such as USDT.
- Re-registering an existing custom code needs replace: true.
- Identity is code + exponent: a hand-built Currency('EUR', 3, …) is a different currency, and arithmetic between the two throws.
- Register at boot only — Octane workers share the registry singleton.
- Withdrawn codes (HRK, SKK, BGN) are not bundled; register them as custom currencies if you need historic data.

## Restricting input currencies

currencies.allowed limits which currencies users may choose — it drives the CurrencyCode rule and MoneyAmount::inCurrencyFrom() — without ever restricting data you already store.

## Listing the registry

```bash
php artisan money:currencies                    # the whole registry
php artisan money:currencies --iso              # only bundled ISO 4217 currencies
php artisan money:currencies --custom           # only custom currencies
php artisan money:currencies --code=USD --code=CZK
```

Without the facade, inject the RoundlyConsulting\\Money\\Contracts\\CurrencyRegistry contract — the same singleton Currencies resolves.
