✦ What is SignMarket?
SignMarket turns any sign + chest combo into a fully automated player shop complete with 3D floating item displays, real-time stock tracking, Discord notifications, and an SQLite-backed transaction history. No complicated GUIs, no lag, no drama. Just place a sign, link your chest, and you're selling.
Built from scratch on Paper 1.21 with a focus on performance and reliability. Every design decision was made with large servers in mind.

✦ Feature Highlights
Virtual Floating Item Displays- Items float above every shop sign fully 3D, rotating, visible from configurable range
- Powered by PacketEvents zero real entities, zero entity count impact on the server
- Per-player rendering each player sees only what's in their view distance
- Staggered chunk loading so displays spawn smoothly without stuttering on server start
- Automatically switches to vanilla entity backend if PacketEvents is not installed
SQLite Database No Data Loss- All transaction history stored in a local SQLite database survives restarts, never corrupts
- Full transaction log: buyer, owner, item, quantity, price, world coordinates, timestamp
- Write-Ahead Log (WAL) crash recovery if the server crashes mid-purchase, money is automatically refunded on next start using the correct currency
- Per-player purchase limit tracking per shop (table ready, configurable)
- Async writes database never blocks the main thread
Multi-Currency Support- Vault works with any Vault-compatible economy (EssentialsX, CMI, etc.)
- PlayerPoints zero-dependency detection via reflection; just install PlayerPoints and it works
- Each shop independently selects its currency at creation time
- Per-currency configurable symbols shown on signs, messages, and /sm info
- Whole-number enforcement for point-based currencies
- Crash recovery refunds in the original purchase currency
Trusted Players- Shop owners can grant trusted status to other players
- Trusted players can restock the chest and view the shop, but cannot buy from it
- Add/remove with /sm trust and /sm untrust takes effect immediately, no restart needed
- Trusted list saved to disk and persists across restarts
Discord Webhook Integration- Rich embeds for: large transactions, new shop created, shop stocked, shop removed, suspicious price alerts
- Configurable per-event toggle enable only what you want
- Configurable transaction threshold for "large purchase" alerts
- Debug logging mode for testing webhook delivery
Admin & Economy Tools- Suspicious price alerts notify admins in-game when a shop is created at an unusual price
- Per-item price limits set min/max price per Minecraft material
- Item blacklist prevent specific items from being sold (Bedrock, Command Block, etc.)
- Global min/max price boundaries
- Max shops per player (bypass permission available)
- Max shops per chunk prevents display lag in dense market areas
Admin Commands- /sm list browse all shops on the server, paginated
- /sm inspect click any sign to see full shop details, owner, stock, currency
- /sm teleport <id> teleport directly to any shop by ID
- /sm stats server-wide economy statistics
- /sm disable <player> block/unblock a player from creating shops
- /sm reload hot-reload config without restarting
Bedrock / Floodgate Support- Bedrock players (via Floodgate) can create shops using a book-based input form
- Full parity with Java edition shop creation flow
Performance- In-memory stock cache sign reads never touch the chest inventory
- Cache refreshed on chest close, chunk load, purchase, and startup
- Single-threaded executor for all database writes no lock contention
- Staggered display spawning no lag spike on startup or chunk load

✦ FAQ
No PacketEvents is optional. Without it, SignMarket falls back to vanilla display entities. However, PacketEvents is strongly recommended for large servers as it eliminates entity count overhead entirely.
Yes install Floodgate alongside the plugin. Bedrock players get a book-based input form since they cannot type on signs the same way as Java players.
SignMarket uses a Write-Ahead Log (WAL). If the server crashes after money is taken but before items are given, the pending transaction is detected on next startup and the buyer is automatically refunded in the correct currency.
Yes — per shop. Just install PlayerPoints and use /sm setup <price> 1 playerpoints. Vault shops and PlayerPoints shops can coexist on the same server.
Configurable. Set max-shops-per-player in config.yml. Players with signmarket.bypasslimit permission bypass this. Set to 0 for unlimited.
Configurable. Set max-shops-per-player in config.yml. Players with signmarket.bypasslimit permission bypass this. Set to 0 for unlimited.
Coming in a future update. The transaction history and stats system is already in place to power it.
