On-Chain Auto-Donate Yield Feature

[edehvictor]

📝 Description

Allow users to easily support public goods. We want a feature where users can toggle a setting to automatically route a percentage of their generated yield to a whitelisted charity address.

🎯 Acceptance Criteria

• Update the Vault smart contract to support a yield_split parameter per user.
• Modify the harvest/withdrawal logic to route the specified percentage to the designated charity address.
• Build a frontend UI component ("Yield for Good") allowing the user to select the percentage and the charity.
• Add a public dashboard showing total protocol-wide donations generated.

🛠 Technical Details

• Stack: Rust (Soroban), React, Node.js.
• Location: /contracts/yield_vault/src/donations.rs
• Security: Ensure the donation logic cannot underflow or trap user principal funds.

⏱ Complexity & Scope

• Estimated Time: 2-3 weeks.
• Drips Complexity: High (200 points) - Smart contract state updates and full-stack integration.

📋 Guidelines for Submission

• Minimum 90 percent test coverage required.
• Clear NatSpec-style documentation must be added to public contract functions.
• Timeframe for completion: 2 Wave cycles.
