    About

    Arcadia Lib is a shared support library for Arcadia Pets, Prestige, and the Auction House; it adds no standalone gameplay, but provides services and interfaces those mods can use. It supplies shared player data, a database layer for multi-server setups, and a configurable economy that can use Numismatics, item currency, or a virtual emerald wallet, with LuckPerms permissions when available and operator checks as a fallback. The /arcadia hub brings installed Arcadia mods together in a shared menu and dashboard, while the library also provides APIs for features such as hub cards, dashboard tabs, achievements, teleports, and cooldowns. Server staff can use staff chat, timed mutes with alerts, and role-based staff tools; the library also includes 21 staff pet entities so Arcadia Pets can run without Prestige.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Changes the game's code in 1 area, as a library other mods build on: User interfaceChanges 1 game code file in this area: menus, screens, tooltips, the chat window and the in-game overlay..

    Adds 2 items, 21 entities and 1 key binding.

    Counted from the names and data files in the mod, so the list may not be complete.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found in the parts we could check

    We checked its files and read their code, without running it.

    One of its files for recent versions is not checked yet.

    What it can do on your computer

    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Found in mysql-connector-j, a library it includes.
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Found in HikariCP, a library it includes and in mysql-connector-j, a library it includes. See Privacy

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · 3 of 4 latest files checked, last on 18 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      4 latest files: the newest file for each Minecraft version and loader. All 4 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. 1 of them is not checked yet. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends, in the 3 of its 4 files we read

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · 3 of 4 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of 3 of 4 files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
