Launchpad v7

[pileks]

Summary

Introduces launchpad v7 with approval-based funding mechanism, allowing launch authorities to review and approve funding commitments before token distribution.

Key Functional Changes

Approval-Based Funding Flow

• Launch authority reviews and approves/rejects funding records via set_funding_record_approval
• Token distribution based on approved amounts rather than total committed

Launch Completion

• Requires total approved amount ≥ minimum raise amount
• Distributes tokens proportionally based on approved contributions
• Rejected funders can claim refunds for unapproved amounts

Backwards Compatibility

• v6 remains unchanged and fully supported
• Separate SDK clients for v6 (LaunchpadClient) and v7
• Independent test suites

Program Details

• Program ID: moontUzsdepotRGe5xsfip7vLPTJnVuafqdUWexVnPM
• New instruction: set_funding_record_approval for approval workflow
• Maintains integration with Futarchy, DAMM v2, and performance packages
