Important: hackathon fees may not be collected (config drift)

[0xdevcollins]

Severity: Important (revenue)

core_escrow.FeeConfig defines hackathon_fee_bps: 400 (4%), but create_hackathon calls core_escrow.create_pool directly — no fee path visible. Crowdfund uses route_pledge which IS fee-aware. Hackathons appear to bypass fee collection.

Action

1. Confirm whether the platform currently collects fees on hackathons.
2. If yes: trace where the deduction happens and document.
3. If no: decide product question — should hackathons have a creator fee? If yes, add fee path before mainnet.

Tests (if fee added)

• 1000 USDC pool creation deducts 40 USDC to treasury, 960 to pool
• Fee config update reflected in subsequent creates
• No fee on cancellation refund
