YASCurrency

YASCurrency is a native Hytale currency, wallet, cash, HUD, transaction, storage, and economy-control system for servers.

It combines digital player balances, immersive physical cash items, configurable wallets, player HUDs, transaction history, QuestLines support, VaultUnlocked support, shop integration support, multilingual UI, optional MariaDB storage, storage diagnostics, migration tools, and a public developer API into one complete economy foundation.

Major Economy Control Update:
YASCurrency is no longer just a currency plugin. It is now a full server economy management system with transaction monitoring, fee and tax handling, rollback tools, source blocking, player account inspection, cash/digital tracking, inflation-control options, reward scaling, optional MariaDB support, storage diagnostics, migration tools, and API v4 support for structured integrations.

Whether you run a simple server economy, a roleplay cash system, a quest-driven RPG server, a shop network, a player market, or a large economy with multiple plugins, YASCurrency gives you the tools to monitor, manage, protect, store, migrate, and scale your money flow.

Major Update: Economy Control

This update adds a full economy-control layer on top of the existing YASCurrency wallet, cash, HUD, and transaction system.

Transaction monitoring for digital and cash-based economy activity.
Economy dashboard for money creation, money destruction, transfers, warnings, and total supply.
Admin transaction journal with filtering, player lookup, source inspection, and transaction details.
Rollback support through safe counter-transactions instead of deleting ledger history.
Source and external-ID blocking for suspicious or unwanted transaction flows.
Per-player account inspection with player-specific transaction history.
Pagination for player account history inside the admin account tools.
Configurable fees and taxes for transfers, shops, PlayerShops, cash, QuestLines rewards, and claim payments.
Optional inflation control with configurable daily mint limits and large-transaction warnings.
Optional dynamic reward scaling for advanced server economy balancing.
Storage diagnostics for checking the active backend, health, account count, transaction count, and total money supply.
API v4 with structured transaction contexts, fee policies, previews, and result objects.

Simple servers can keep the advanced controls disabled and use YASCurrency as a clean wallet and cash system. Larger servers can enable monitoring, limits, fees, MariaDB storage, storage diagnostics, migration tools, and advanced economy controls when they need deeper control.

New: Optional MariaDB Storage Backend

YASCurrency now supports MariaDB as an optional storage backend in addition to the default SQLite storage.

SQLite remains the default and recommended storage option for most single-server setups. Existing servers continue to work with SQLite without any required external database setup or migration.

MariaDB is intended for larger servers, hosted environments, external database management, or administrators who prefer storing economy data in a dedicated database server.

SQLite remains the default backend and requires no external database.
MariaDB can be enabled manually through the YASCurrency config.
Automatic table creation is supported when the MariaDB database already exists.
Storage diagnostics help admins verify which backend is currently active.
SQLite to MariaDB migration is available through an explicit admin command.
No automatic backend switch is performed after migration, so admins stay fully in control.

This makes YASCurrency flexible for both simple local server setups and larger production environments.

Storage Setup: SQLite or MariaDB

YASCurrency can run with either SQLite or MariaDB.

SQLite Default Storage

SQLite is the default storage backend. It is simple, reliable, and requires no external database server.

storage.type=sqlite
storage.file=yascurrency.sqlite

This is the recommended setup for most small and single-server installations.

MariaDB Optional Storage

MariaDB can be enabled manually for larger or externally managed server setups.

storage.type=mariadb
mariadb.host=localhost
mariadb.port=3306
mariadb.database=yascurrency
mariadb.username=yascurrency
mariadb.password=change-me
mariadb.useSsl=false
mariadb.connectionTimeoutMs=5000
mariadb.autoCreateTables=true

The MariaDB database and database user must be created by the server administrator. YASCurrency can create the required tables inside the existing database when mariadb.autoCreateTables=true is enabled.

Example MariaDB Preparation

CREATE DATABASE yascurrency
  CHARACTER SET utf8mb4
  COLLATE utf8mb4_unicode_ci;

CREATE USER 'yascurrency'@'localhost' IDENTIFIED BY 'your_password';

GRANT ALL PRIVILEGES ON yascurrency.* TO 'yascurrency'@'localhost';

FLUSH PRIVILEGES;

Storage Diagnostics

Admins can verify the active backend and storage health with:

/yascurrency storage test
/yascurrency storage status

The diagnostics show the active backend, storage description, health status, account count, transaction count, and total money supply.

SQLite to MariaDB Migration

YASCurrency includes an explicit migration command for moving from SQLite to MariaDB:

/yascurrency storage migrate sqlite-to-mariadb

The migration command:

Checks that SQLite is currently active.
Creates a SQLite backup before importing data.
Initializes the MariaDB target schema.
Copies accounts, transactions, and metadata.
Refuses to import into a MariaDB database that already contains YASCurrency data.
Compares account count, transaction count, and total money supply after migration.
Reports whether the migration finished with OK or WARNING status.

Important: YASCurrency does not automatically switch to MariaDB after migration. After a successful migration, set storage.type=mariadb manually in the config and restart the server.

Useful for roleplay servers, market stalls, player trading hubs, survival economies, and physical economy setups.

Note: YASCurrency controls official YASCurrency cash flows. Server owners should ensure that other plugins do not create or duplicate cash items outside the supported economy pipeline.

Economy Monitoring & Security

Transaction monitoring is enabled by default.
Monitor money creation, money destruction, transfers, warnings, and total economy supply.
Review large transactions and suspicious money movement.
Inspect transactions by player, source, type, amount, reason, and external ID.
Open a transaction source as a filter.
Open a player directly in the account management tab from a transaction.
Review player-specific transaction history.
Use warnings and risk levels to identify suspicious activity faster.

This system is designed to help server owners understand where money enters the economy, where it leaves the economy, and which systems are responsible for major changes.

Rollback & Blocking Tools

Rollback creates a safe counter-transaction instead of deleting history.
Blocking can block a transaction source or external ID.
Admin confirmation dialog prevents accidental rollback or blocking actions.
Rollback and block actions are designed for economy investigations and administrative corrections.
Ledger history remains traceable, making the economy more auditable.

YASCurrency does not silently erase financial history. Instead, it keeps the transaction trail understandable and reviewable.

Fees & Taxes

YASCurrency supports configurable fees and taxes for multiple economy flows.

Transfer fee
Shop fee
PlayerShop tax
Cash withdrawal fee
Cash deposit fee
QuestLines reward fee
Claim purchase fee
Claim rent / renewal fee

Fees can be shown in player-facing transaction history when transaction metadata includes the fee information. This helps players understand why a payment, reward, claim purchase, or rent action changed their balance by a specific amount.

Inflation Control

YASCurrency includes optional inflation-control features for larger or more complex server economies.

Global daily money creation limit.
Daily money creation limit per player.
Large-transaction warning threshold.
High daily-gain warning threshold.

The wallet shows digital balance, physical cash in inventory, active cash profile, and recent activity.
Dedicated HUD tab for player-specific Balance HUD settings.
Recent transactions are displayed in a readable history list.
Income and expense filters help players understand where money came from and where it was spent.
Filtered totals show summed income or outgoing payments for the selected view.
Technical audit entries are hidden from normal player-facing transaction history.
Shop transactions can display cleaner labels when the source plugin provides structured transaction reasons.
Fees can be displayed in the transaction history when the transaction contains structured fee metadata.

API & Developer Support

YASCurrency includes a public API for plugin developers and server-side integrations.

Public API v4 for balance checks, cash checks, deposits, withdrawals, transfers, cash spending, cash grants, previews, results, HUD helpers, feature flags, and transaction handling.
Feature flags allow integrations to check available functionality.
Supports digital balance formatting and physical cash balance formatting.
Supports Balance HUD refresh and player HUD setting helpers.
Supports structured transaction reasons so external systems can pass readable context such as shop, offer, item, quantity, reward source, claim ID, quest ID, fee policy, or payment reason.
Useful for shops, quests, jobs, rewards, NPC systems, claims, server commands, and custom integrations.
API and End User Docs are available here: https://api-yas-currency.web.app/

API v4 Highlights

TransactionContext for structured transaction metadata.
FeePolicy for explicit fee handling.
TransactionPreview for showing players the final cost before charging.
YasCurrencyTransactionResult for rich success/failure responses.
TransactionStatus for better integration logic.
Preview methods for deposit, withdraw, and transfer operations.
Context-aware methods for deposit, withdraw, transfer, cash grant, and cash spend operations.

API v4 is designed so integrations no longer need to rely only on plain reason strings. Instead, they can pass source, category, external ID, display reason, metadata, and fee policy in a structured way.

Example: Quest Reward Context

TransactionContext ctx = YasCurrencyAPI.questRewardContext(
    questId,
    questName,
    "QuestLines"
);

TransactionPreview preview = YasCurrencyAPI.previewDeposit(playerUuid, rewardAmount, ctx);
YasCurrencyTransactionResult result = YasCurrencyAPI.deposit(playerUuid, rewardAmount, ctx);

Example: Claim Rent Context

TransactionContext ctx = YasCurrencyAPI.claimRentContext(
    claimId,
    claimName,
    durationDays,
    "QuestLines Claims"
);

TransactionPreview preview = YasCurrencyAPI.previewWithdraw(playerUuid, rentAmount, ctx);
YasCurrencyTransactionResult result = YasCurrencyAPI.withdraw(playerUuid, rentAmount, ctx);

Example: Shop Purchase Context

TransactionContext ctx = TransactionContext.builder()
    .source("YetAnotherShop")
    .category(TransactionCategory.SHOP_PURCHASE)
    .feePolicy(FeePolicy.SHOP_BUY)
    .externalId(orderId)
    .displayReason("Shop purchase: " + itemName)
    .metadata("item", itemName)
    .metadata("quantity", String.valueOf(quantity))
    .build();

TransactionPreview preview = YasCurrencyAPI.previewWithdraw(playerUuid, price, ctx);
YasCurrencyTransactionResult result = YasCurrencyAPI.withdraw(playerUuid, price, ctx);

Localization

English and German language files included.
Configurable default language.
Player-facing wallet, transaction, HUD, QuestLines, and admin text is localized where supported.
Designed for multilingual Hytale servers.
The admin UI is designed to use language files instead of hardcoded visible UI text.
