Fiat Off-Ramp Integration ("Zap-Out to Bank")

[edehvictor]

📝 Description

The ultimate DeFi UX allows users to exit straight to their bank account. We need an integration with a fiat off-ramp (like MoonPay or a local Stellar Anchor) to allow one-click withdrawals to fiat.

🎯 Acceptance Criteria

• Integrate a fiat off-ramp provider's SDK into the withdrawal flow.
• Build the UI flow allowing users to select "Withdraw to Bank Account."
• The system must construct a transaction that withdraws vault shares for USDC, then sends that USDC directly to the off-ramp's deposit address with the correct memo.
• Provide clear UI tracking for the status of the fiat wire transfer.

🛠 Technical Details

• Stack: React, API Integrations, Stellar SDK.
• Location: /frontend/src/features/offramp/
• Security: Strict handling of destination addresses and memos to ensure user funds aren't lost in transit to the exchange.

⏱ Complexity & Scope

• Estimated Time: 3 weeks.
• Drips Complexity: High (200 points) - Complex third-party payment flow and state tracking.

📋 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.
