Bounty Reward

Reward: 1000 MRG

Goal

Implement and verify the PayPal Sandbox payment workflow for MergeOS project funding so a test customer can fund a project, the backend can confirm the sandbox payment state, MRG token credit can be minted, and the proof ledger/admin views reflect the result correctly.

Scope

• Use PayPal Sandbox credentials and sandbox endpoints only.
• Validate the customer funding path from project creation to payment confirmation.
• Confirm funded projects mint the expected internal MRG token credit.
• Confirm the admin payment/ledger review screen shows the payment result.
• Confirm the public proof ledger shows sanitized payment proof without leaking private user data.
• Keep production credentials and real payment flows untouched.
