boolean success = EconomyAPI.removeCurrency(playerUUID, "coins", 50);

// Set balance
EconomyAPI.setBalance(playerUUID, "coins", 1000);

Transfer Operations

// Player-to-player transfer
boolean success = EconomyAPI.transfer(fromUUID, toUUID, "coins", 100);

// Check sufficient balance
if (EconomyAPI.hasEnough(playerUUID, "coins", 100)) {
    // Execute operation
}

Currency Management

// Check if currency exists
boolean exists = EconomyAPI.currencyExists("gems");

// Get all currencies
