mplements the Stellar Horizon Path Payment Claim feature that allows users to claim their vesting tokens and instantly swap them for USDC in a single transaction. This "Auto-Exit" feature provides a massive UX improvement for team members who need immediate access to liquid funds for real-world expenses.
Issues Addressed
#146: Implement Stellar_Horizon_Path_Payment_Claim
#93: Auto-Exit feature for instant token-to-USDC conversion
Features Implemented
Core Functionality
configure_path_payment(): Admin function to set up destination asset (USDC), minimum amounts, and swap paths
claim_with_path_payment(): Main user function that claims tokens and executes path payment in one atomic transaction
simulate_path_payment_claim(): Gas-free simulation to preview expected amounts and execution feasibility
disable_path_payment(): Admin function to disable the feature when needed
Smart Contract Integration
Seamless integration with existing vesting vault infrastructure
Maintains compatibility with regular claim functionality
Respects emergency pause and other security measures
Proper event emission for indexing and frontend integration
Advanced Features
Custom Swap Paths: Support for multi-hop token swaps (Token → Asset1 → Asset2 → USDC)
Minimum Amount Protection: Users can set minimum destination amounts to prevent slippage
Fallback to Config: If no custom minimum provided, uses admin-configured default
Comprehensive Error Handling: Clear error messages for all failure scenarios
closes #146
