Enhance Slack Task Funding and Coin Details Services

Description

Summary of Work

This pull request consolidates recent improvements to our Slack task funding mechanism and cryptocurrency details service:

Key Improvements

• Implemented robust Slack request verification with security best practices
• Added support for funding both standard and KPL (Koii Protocol Layer) tasks
• Created a flexible coin details route with caching and error handling
• Improved input validation and error management

Architectural Changes

• Separated routing logic for coin details into a dedicated module
• Implemented a caching strategy for cryptocurrency information
• Enhanced security measures for Slack webhook interactions
• Added comprehensive error handling for task funding and coin retrieval

Benefits

• Improved system security through request signature verification
• More flexible task funding support
• Better performance with caching mechanism
• Clear separation of concerns in routing and service logic

Changes Made

1. Added Slack request verification in index.js

   • Implemented timestamp-based replay attack prevention
   • Used constant-time comparison for signature verification

2. Enhanced task funding capabilities

   • Support for both standard and KPL task funding
   • Detailed error handling and Slack response notifications
   • Restricted funding to a predefined list of user IDs

3. Created modular coin details route in src/routes/coinDetails.js

   • Implemented input validation
   • Added error handling middleware
   • Integrated caching with node-cache
   • Used mock data for cryptocurrency details

4. Improved environment and configuration management

   • Leveraged environment variables for sensitive information
   • Added flexible connection handling for different task types
