Enhance Slack-Integrated Task Funding Service with Robust Security and Flexible Funding Mechanisms

Description

Summary of Work

This pull request consolidates critical improvements to our Koii task funding service, focusing on enhancing security, flexibility, and observability for Slack-integrated task funding workflows.

Our goal is to create a more robust and secure mechanism for funding tasks through Slack, with comprehensive user authorization, secure request validation, and flexible support for different token types.

Key Objectives:

• Implement industry-standard security practices for Slack integrations
• Support multiple token funding mechanisms
• Provide clear, actionable feedback for users
• Improve system observability and error handling

The changes represent a significant step forward in making our task funding service more reliable, secure, and user-friendly.

Changes Made

Security and Authentication Improvements:

• Implemented comprehensive Slack request signature verification
• Added constant-time comparison to prevent timing-based attacks
• Enhanced request timestamp validation to prevent replay attacks
