• Third-Party Fees (e.g., gas fees, bank transfer charges)
• Total Deduction
Backend Integration:
• Profit fee and third-party fees will be calculated and tracked separately for analytics and reporting.
5. Crowdfunding Feature
Temporary Wallet System:
1. Campaign-Specific Wallet:
• Each crowdfunding campaign will have a unique temporary wallet where all funds (including P2P contributions) will be stored.
• The wallet is created automatically when a campaign is launched and is linked to the campaign creator’s WinkPay account.
2. Funds Allocation:
• All funds raised through various channels (credit/debit cards, Apple Pay, Google Pay, crypto deposits, and P2P transfers) will be deposited into the temporary wallet.
• Contributions are considered donations and are non-refundable, even if the campaign fails to meet its goal.
3. Withdrawal to WinkPay Wallet:
• Once the campaign target is met or the campaign duration ends, the funds are released to the campaign creator’s WinkPay wallet.
• Campaign creators can then use the funds for transactions, withdrawals, or transfers within WinkPay.
Key Features:
1. Real-Time Tracking:
• Contributors and campaign owners can view real-time updates of the funds in the temporary wallet.
• Progress bars to display how close the campaign is to reaching its target.
2. Finality of Donations:
• Contributions are final and non-refundable.
• A disclaimer will be displayed at the point of contribution, informing users of the no-refund policy.
3. Integration with P2P Transfers:
• Funds sent via P2P transfers to the campaign will also be directed to the temporary wallet.
Transparency and Updates:
• Campaign creators can post updates and milestones to keep contributors informed.
• Notifications are sent to contributors regarding campaign progress.
