Trading Process Workflow

Initiating Trade: Player approaches another player (within configurable radius, typically 3-5 meters) and opens trading menu selecting target player. Target receives notification with trader's name and can accept or decline. Upon acceptance, trade window opens for both players simultaneously.

Adding Offerings: Each player independently adds items from their inventory and/or money to their side of trade. As items are added, they appear in real-time in both players' trade windows. Players can remove items before final confirmation. Weight checks ensure receiving player has inventory space.

Confirmation Phase: When both players are satisfied with offerings, each clicks Accept button. First acceptance shows Waiting for other player status. Once both accept, short countdown (3-5 seconds) begins allowing final review. Either player can still cancel during countdown.

Trade Execution: After countdown, items and money are simultaneously transferred between inventories. Server validates all transfers preventing duplication. Success notification appears for both players. Trade window closes automatically. Transaction logged to history.

Cancellation: Either player can click Cancel at any point before final countdown. All offered items instantly return to original owners. Trade window closes with cancellation notification.

Anti-Scam Protections

Server-Side Validation: All trades execute server-side with validation checks ensuring players actually own offered items, sufficient inventory space exists for receiving items, money amounts are accurate and within limits, items aren't duplicated during transfer, and metadata is correctly preserved. Client-side displays are verified against server authority preventing manipulation.

Confirmation System: Dual confirmation requirement prevents quick switch scams where traders change offerings last second. The 3-5 second countdown after both accept provides final review opportunity. Real-time updates show exactly what each player is offering before execution.

Distance Enforcement: Trades automatically cancel if players move too far apart during transaction preventing situations where one player runs away during trade. Proximity check runs continuously during entire trade process.

Trade Logging: Complete transaction logs enable admins to investigate disputed trades, verify what was exchanged, identify scam attempts, and resolve conflicts with evidence. Logs include player identifiers, items traded, quantities, timestamps, and trade success/cancellation status.

Trade History & Logging

Every completed trade is logged to database with comprehensive information including both player identifiers (license, steam, etc.), all items exchanged with quantities, money amounts transferred, exact timestamp, and trade success status. Admins can query trade history to investigate suspicious activity, resolve player disputes about missing items, track market activity and popular items, identify potential exploits or unusual patterns, and provide evidence for ban appeals or reports.

Optional Discord webhook integration sends real-time notifications of high-value trades (configurable threshold) helping admins monitor economy for manipulation or RMT (real money trading) attempts.

Integration Possibilities

• Shop Scripts: Business owners can trade inventory stock to their shops rather than using admin commands
• Job Systems: Facilitate job-to-job trading like mechanics buying parts from suppliers or chefs purchasing ingredients
• Gang Systems: Gang members trade weapons, drugs, or resources within organization
• Housing Scripts: Trade furniture items, property keys, or housing decorations between players
• Vehicle Scripts: Exchange vehicle ownership through trade system (if configured to support vehicle items)
• Crafting Systems: Players trade raw materials or crafted goods supporting production chains

What Makes It Stand Out

CodeM Trading Script eliminates the dangerous practice of drop trading where players drop items on ground hoping other player will pay. Drop trading is easily exploitable - players can run away with items, third parties can grab dropped items, or scammers can claim they never received goods. This script provides secure, transparent, simultaneous exchange where nobody can take items without giving agreed offerings. The real-time interface shows exactly what each player is offering before execution preventing bait-and-switch scams. The dual confirmation with countdown prevents rushed decisions. Most importantly, server-side validation makes exploits and duplication impossible creating trusted trading environment even on public servers.

Economy Enhancement

Secure trading enables genuine player-driven economy where players specialize in gathering, crafting, or reselling creating market dynamics. Resource gatherers sell raw materials to crafters who sell finished products to consumers establishing supply chains. Price discovery happens naturally through negotiation rather than fixed NPC prices. Trading creates social interaction - players must communicate, negotiate, and meet in-person rather than using impersonal auction houses. This generates organic roleplay and community building.

Use Case Examples

Merchant Roleplay: Player establishes marketplace stall and trades with customers using this system. Customers browse inventory, negotiate prices, and complete secure trades. Merchant tracks sales through trade history managing inventory turnover.

Drug Deals: Criminal sells drugs to another player through trade system. Both parties confirm quantities and payment before execution. If police interrupt, either can cancel trade instantly. No dropped evidence to collect.

Equipment Sales: Mechanic crafts vehicle parts and trades them to customers. Customer pays cash, receives parts, transaction complete. Mechanic has proof of sale in trade history if customer later disputes.

Resource Trading: Miner sells ore to crafter. Crafter processes into bars and sells to weaponsmith. Weaponsmith crafts guns and sells to gang members. Complete production chain facilitated by secure trading.

Admin Features

Server administrators have special controls including viewing complete trade history database, searching trades by player identifier, filtering by item type or value, exporting trade logs for analysis, identifying suspicious trading patterns, and optionally blocking specific players from trading (cooldown or blacklist). Admin panel provides insights into server economy including most traded items, average transaction values, and trading activity by time of day.

Support & Updates

Includes lifetime updates with new features, framework compatibility updates, security patches, and bug fixes. Comprehensive documentation covers installation, configuration, inventory system integration, troubleshooting, and best practices for economy management. Active support via ticket system for technical assistance and customization help. Regular updates add community-requested features like vehicle trading, trade templates, and advanced filtering.
