Each contains +Pre-conditions, Steps, Impact, Mitigation, and the test reference where the +defense is exercised. + +--- + +## AS-01 — Sybil referral tree (vertical farm) + +**Pre-conditions:** No depth cap on rewarded levels; no minimum activity per +ancestor. +**Steps:** +1. Attacker generates 10 000 EOA addresses A0…A9999. +2. Calls `register(Ai, Ai-1)` for each → linear chain. +3. From A9999 performs a single 1 000 USDC swap on the bonding curve. +4. Reward loop walks 9 999 ancestors, all controlled by attacker → 100 % of + referral cashback flows back to attacker as one bundle. + +**Impact:** Critical — protocol pays full referral budget on every swap. +**Mitigation:** `MAX_REFERRAL_DEPTH = 10` for distribution; only first 10 +ancestors credited. Per-ancestor minimum: must have at least one prior +self-funded swap of ≥ 5 USDC equivalent (anti-sybil "skin in the game"). +**Test:** `test/invariants/SybilDepthBound.t.sol::test_sybil_chain_caps_at_10`. + +--- + +## AS-02 — Front-run referrer registration + +**Pre-conditions:** `register(user, ref)` permits any `msg.sender` to write +`referrerOf[user]`; user has not yet registered. +**Steps:** +1. Attacker watches mempool for a victim's first `register(victim, friend)` tx. +2. Front-runs with `register(victim, attacker)`. +3. Victim's tx reverts (already registered). +4. Attacker gets all victim's lifetime cashback. + +**Impact:** High — permanent referrer hijack. +**Mitigation:** `register(referrer)` only — `msg.sender` is the registree; +nobody else can register on someone's behalf. Optional EIP-712 sponsored path +requires victim's signature. +**Test:** `test/referral/Register.t.sol::test_cannot_register_someone_else`. + +--- + +## AS-03 — Sandwich on graduation tx + +**Pre-conditions:** Graduation is executed atomically with the swap that +crosses the threshold; AMM pair is created and seeded in the same block. +**Steps:** +1. Attacker observes mempool, sees a buy that will cross graduation threshold. +2. Front-runs with massive buy on the curve at favorable price. +3. Threshold-crossing tx executes; AMM pair is created at high price. +4. Back-runs by selling on the new AMM at premium. + +**Impact:** High — extracts arbitrage spread, distorts initial AMM price. +**Mitigation:** Two-phase graduation: +- Phase 1: threshold reached → curve frozen, `graduationPending = true`. +- Phase 2: anyone can call `executeGraduation()` after `gradPendingBlock + 5`. +- Curve cannot be bought between phases. +**Test:** `test/migration/Graduation.t.sol::test_no_atomic_sandwich`. + +--- + +## AS-04 — Reentrancy on `claim` + +**Pre-conditions:** Claim transfers paymentToken before zeroing +`pendingRewards`. PaymentToken is an ERC777 or has a hook that calls back. +**Steps:** +1. Attacker registers contract C as their address. +2. Accumulates `pendingRewards[C][token] = 100`. +3. Calls `claim(token)` → contract transfers 100 → C's hook re-enters claim → + reads pending = 100 (not yet zeroed) → drains. + +**Impact:** Critical — multiplied withdraw. +**Mitigation:** +- `nonReentrant` on `claim`. +- Checks-effects-interactions: zero `pendingRewards` BEFORE transfer. +- Only whitelist standard ERC20 paymentTokens (no ERC777, no fee-on-transfer + by default). +**Test:** `test/referral/Reentrancy.t.sol::test_claim_reentrancy_blocked`. + +--- + +## AS-05 — Approval drain via malicious router + +**Pre-conditions:** UI asks user to `approve(router, type(uint256).max)` so +swaps can be one-click. +**Steps:** +1. User approves max to `FRouter`. +2. Owner-controlled router contract is upgraded to malicious version that + calls `paymentToken.transferFrom(user, attacker, balance)` directly. + +**Impact:** Critical — full wallet drain of approved token. +**Mitigation:** +- `FRouter` is **non-upgradeable** (immutable bytecode). +- For the upgradeable bonding contract, never grant infinite approval; + router takes per-swap exact-amount transferFrom. +- UI prompts approval for `amountIn` only, not max. +**Test:** Manual review + `slither --detect arbitrary-from-in-transferFrom`. + +--- + +## AS-06 — Price manipulation on curve via flash loan + +**Pre-conditions:** Curve has no per-tx max buy / max sell. +**Steps:** +1. Attacker flash-loans 10M USDC. +2. Atomic: buy 99 % of curve supply → price spike → sells 99 % back. +3. Pays trading fee but extracts MEV from any concurrent tx priced off the + curve oracle (e.g. another protocol reading curve price). + +**Impact:** Med — third-party oracle abuse, also griefs honest buyers. +**Mitigation:** +- Per-tx max buy: `min(2 % curveSupply, 10 % paymentReserve)`. +- Curve price is NOT exposed as oracle — explicitly documented. +- Optional: rate-limit by block (one buy/sell per address per block). +**Test:** `test/bonding/MaxBuy.t.sol::test_atomic_buy_sell_capped`. + +--- + +## AS-07 — Owner sets tax = 100 % + +**Pre-conditions:** `setTaxBps(uint)` has no upper bound check. +**Steps:** +1. Compromised owner key calls `setTaxBps(token, 10000)`. +2. Next swap takes 100 % as tax; user receives 0 tokens but loses paymentToken. + +**Impact:** Critical — total user fund loss on next swap. +**Mitigation:** Hard-coded constant `MAX_TAX_BPS = 1000`. `setTaxBps` reverts +if `> MAX_TAX_BPS`. Even if owner key is compromised, max extraction is 10 %. +**Test:** `test/bonding/Tax.t.sol::test_setTaxBps_above_cap_reverts`. + +--- + +## AS-08 — Cyclic referral tree via batchImport + +**Pre-conditions:** `batchImport(users[], refs[])` does not validate cycles. +**Steps:** +1. Owner imports `(A, B)` then `(B, A)`. +2. Distribution loop walks A → B → A → … OOG revert OR + if loop bound exists, A and B drain each other's cashback indefinitely. + +**Impact:** High — distribution DoS or double-counting. +**Mitigation:** `batchImport` validates each pair: walk up from `ref` for +`MAX_REFERRAL_DEPTH` steps; if `user` appears, revert. Plus runtime depth +counter clamps loop unconditionally. +**Test:** `test/referral/BatchImport.t.sol::test_cyclic_import_reverts`. + +--- + +## AS-09 — Griefing via revert-on-receive contract + +**Pre-conditions:** Distribution sends paymentToken atomically to all 10 +ancestors during swap. +**Steps:** +1. Attacker registers a contract C that always reverts on `transfer(C)`. +2. Inserts C as ancestor in honest user's tree (sybil). +3. Honest user's swap reverts because distribution to C fails. + +**Impact:** High — selective DoS on swaps that touch attacker subtree. +**Mitigation:** Distribution is **credit-only** to mapping (`pendingRewards +[C] += x`). No transfer during swap. Transfer only on user-initiated `claim`, +where the only griefable account is C itself. +**Test:** `test/referral/Distribute.t.sol::test_credit_does_not_call_external`. + +--- + +## AS-10 — Token migration LP rug + +**Pre-conditions:** LP tokens minted on graduation are sent to owner instead +of locked. +**Steps:** +1. Owner waits for graduation, receives LP. +2. Calls `removeLiquidity` on the AMM pair. +3. Drains paymentToken reserves. + +**Impact:** Critical. +**Mitigation:** Migrator transfers LP to a hard-coded `LiquidityLocker` with +unlock timestamp ≥ now + 10y. LiquidityLocker is non-upgradeable, no admin +withdraw, only emits LP back to original owner after timestamp. +**Test:** `test/migration/Lock.t.sol::test_lp_locked_10y`. + +--- + +## AS-11 — Read-only reentrancy on `pendingRewards` + +**Pre-conditions:** External integrator (e.g., a vault) reads +`pendingRewards[user][token]` to compute share value mid-callback. +**Steps:** +1. User calls vault deposit; vault has `onTokenReceived` hook. +2. Hook reads `pendingRewards` while a `claim` tx is mid-execution and has + already zeroed but not yet transferred. + +**Impact:** Med — third-party integrator inconsistency. +**Mitigation:** Document atomic semantics; `claim` follows CEI so a hook +inside `claim` can only see "already credited 0". +**Test:** N/A (out of our scope; document for integrators). + +--- + +## AS-12 — Initializer front-run on UUPS proxy + +**Pre-conditions:** Implementation contract deployed but `initialize` not yet +called atomically with proxy creation. +**Steps:** +1. Attacker watches deploy script. +2. Calls `initialize(attackerOwner)` on the implementation directly, + becoming owner of the impl (not the proxy, but a confusing artifact). + +**Impact:** Low (impl is not proxy) but reputation/UI confusion. +**Mitigation:** `_disableInitializers()` in implementation constructor. Deploy +script uses `OpenZeppelin Foundry Upgrades` plugin which atomically deploys + +initializes. +**Test:** `test/upgrade/Initialize.t.sol::test_impl_initialize_disabled`. + +--- + +## AS-13 — Fee-on-transfer payment token desync + +**Pre-conditions:** Owner whitelists a fee-on-transfer token (e.g., SAFEMOON +clone) as paymentToken. +**Steps:** +1. User swaps 100 token in. +2. Curve receives 95 (5 % burn). Internal accounting credits 100. +3. After many swaps, accounting > balance → claims start reverting (insolvent). + +**Impact:** High — protocol insolvency. +**Mitigation:** +- Whitelist allows only standard ERC20 (no transfer-tax, no rebase). +- Each `transferFrom` measured by `balanceBefore/balanceAfter`; only credited + delta. +**Test:** `test/bonding/FeeOnTransfer.t.sol::test_fot_token_rejected`. + +--- + +## Reference: invariant test command + +``` +forge test --match-path test/invariants/*.t.sol -vvv +forge fuzz --match-contract Invariant_ --runs 100000 +``` diff --git a/audit/CHECKLIST.md b/audit/CHECKLIST.md new file mode 100644 index 0000000..3a81797 --- /dev/null +++ b/audit/CHECKLIST.md @@ -0,0 +1,170 @@ +# Per-contract Compliance Checklist + +For each in-scope contract, every box must be checked before audit handoff. +A `[ ]` is a blocker. + +--- + +## Common (applies to ALL contracts) + +- [ ] License identifier `// SPDX-License-Identifier: MIT` (or BUSL where chosen) +- [ ] Pragma pinned: `pragma solidity 0.8.26;` (no `^`) +- [ ] OpenZeppelin imports use exact version `@openzeppelin/contracts@5.x.x` +- [ ] No `tx.origin` anywhere except for explicit refund-self patterns +- [ ] No external `delegatecall` to user-controlled addresses +- [ ] No `selfdestruct` +- [ ] No `block.timestamp` used as randomness source +- [ ] No floating point / fixed-point misuse;

Forging another user's referrer link +- **Vector:** Attacker calls `referralRegistry.register(victim, attacker)` to plant + themselves as referrer of `victim` before `victim` has registered. +- **Impact:** High — attacker steals all of victim's referral cashback forever. +- **Likelihood:** Med (front-running mempool registrations is trivial). +- **Mitigation:** Registration MUST be self-only (`msg.sender` is the registree) OR + go through `register(referrer)` where caller binds themselves. `register(user, ref)` + must be removed or restricted to owner with EIP-712 signed authorization from `user`. + Lazy registration (first swap auto-binds with no overwrite) closes the window. + +### S2. Forging swap origin to credit referral +- **Vector:** Use a malicious router to spoof `tx.origin` or pass arbitrary `address` + into `swapWithReferrer(token, amountIn, referrer, recipient)` so credit goes to + attacker's tree instead of caller's. +- **Impact:** Med — financial misdirection inside the same swap. +- **Likelihood:** Med. +- **Mitigation:** Always credit `msg.sender` as the swapper; never accept caller-supplied + user address. Disallow `tx.origin` in any access path. + +### S3. Owner identity spoofing on chain switch +- **Vector:** Deployer keeps the same `owner` constructor arg across Base/BSC; if one + chain's owner key leaks, attacker poses on the other chain. +- **Impact:** Critical (owner privileges). +- **Likelihood:** Low. +- **Mitigation:** Use distinct multisigs per chain. Document chain → multisig mapping + in `SCOPE.md`. + +--- + +## T — Tampering + +### T1. Modifying another user's pending referral balance +- **Vector:** `pendingRewards[user]` writable by anyone via miscoded internal function. +- **Impact:** Critical. +- **Likelihood:** Low (review surface is small). +- **Mitigation:** All writers internal/private; only `_credit(user, amount)` exposed + to the bonding contract via a single onlyAuthorized path. Withdraw is pull-based + (`claim()` reads `pendingRewards[msg.sender]` only). + +### T2. Tampering with referrer tree post-registration +- **Vector:** Owner or anyone calls `setReferrer(user, newRef)` to re-route an existing + user's payouts. +- **Impact:** High (silent redirect of cashback). +- **Likelihood:** Low (governance-only function). +- **Mitigation:** Tree is **immutable per-user once registered**. No `setReferrer` + function. Owner cannot override. Document this immutability prominently. + +### T3. Bonding curve reserve tampering +- **Vector:** A function (e.g. `sync`, `skim`, or a poorly guarded admin) modifies + the virtual reserves so that `x * y` invariant breaks downward, letting attacker + buy at stale price. +- **Impact:** Critical (drain). +- **Likelihood:** Low. +- **Mitigation:** No external setters on reserves; only `swap()` updates them and + re-checks `K_after >= K_before`. `skim()` removed or restricted to non-tracked tokens. + +### T4. Referral split percentages mutated mid-stream +- **Vector:** Owner front-runs a user's swap with `setReferralBps(higher_value)` and + pockets a windfall. +- **Impact:** Med (governance griefing). +- **Likelihood:** Low. +- **Mitigation:** Bps changes time-locked (24h delay). Hard cap `MAX_REFERRAL_BPS = 3000`. + +--- + +## R — Repudiation + +### R1. Off-chain referral attribution disputes +- **Vector:** User claims they were the referrer but no on-chain proof exists. +- **Impact:** Med (support load, trust). +- **Likelihood:** High (will happen). +- **Mitigation:** Emit `Registered(user, referrer, depth, timestamp)` and `Credited( + referrer, swapper, level, amount, token)` for every level credited. Indexer ingests + events; UI shows tree from on-chain only. + +### R2. Owner action without audit trail +- **Vector:** Owner pauses contract or rotates fee recipient silently. +- **Impact:** Med. +- **Likelihood:** Med. +- **Mitigation:** Every owner-only function emits an event with old/new value and + caller. `Paused(by)`, `FeeRecipientUpdated(old, new)`, etc. + +### R3. Migration / graduation events missing +- **Vector:** Token graduates from bonding curve to AMM; LP creation hidden. +- **Impact:** Med. +- **Likelihood:** Low. +- **Mitigation:** `Graduated(token, dexPair, liquidityToken, lockTimestamp)` emitted + with all addresses. + +--- + +## I — Information disclosure + +### I1. Referral tree fully public +- **Vector:** `referrerOf(user)` public view; tree walkable. +- **Impact:** Low (this is by-design and a feature: transparency). +- **Likelihood:** Always. +- **Mitigation:** Treat as a feature. Document tree visibility in user-facing docs. + Subgraph indexes the full tree. Users join knowing this. + +### I2. Pending rewards as MEV signal +- **Vector:** Sophisticated user front-runs claims to influence price (small effect). +- **Impact:** Low. +- **Likelihood:** Low. +- **Mitigation:** Claims are stablecoin / paymentToken transfers — they don't move the + curve. No mitigation needed. + +### I3. Pre-graduation supply leaks via events +- **Vector:** Bots watch `Buy/Sell` events to predict graduation block, snipe. +- **Impact:** Low (this is normal launchpad UX). +- **Likelihood:** High. +- **Mitigation:** Time-lock graduation execution by N blocks once threshold hit, so + no atomic threshold-cross-and-snipe. + +--- + +## D — Denial of service + +### D1. Gas grief on `claim()` +- **Vector:** Attacker registers a contract that reverts on token receive, gets + credited, then claim path of upstream referrers reverts. +- **Impact:** High (frozen rewards). +- **Likelihood:** Med. +- **Mitigation:** Pull-based per-user claim (only the receiving address ever pays gas + for its own claim, and a revert only blocks that address — not the parent or + others). Use `transfer` with try/catch fallback to pendingRewards if non-EOA hostile. + +### D2. Loop bomb on multi-level distribution +- **Vector:** 100-level deep tree triggers loop on every swap, gas exceeds block limit + or makes swaps expensive enough that users avoid. +- **Impact:** High. +- **Likelihood:** Med (sybil farms can build deep trees). +- **Mitigation:** Hard cap depth at `MAX_REFERRAL_DEPTH = 10` for distribution + purposes (deeper registrations allowed but unrewarded). Per-level credit O(1) via + cached `referrerOf` chain — bounded loop. + +### D3. `batchImport` gas DoS +- **Vector:** Owner calls `batchImport(huge_array)` and TX runs out of gas leaving + partial state. +- **Impact:** Low (owner-only). +- **Likelihood:** Low. +- **Mitigation:** `batchImport` has a max length of 200 per call; documented chunking. + +### D4. Unbounded pendingRewards token list +- **Vector:** Multiple paymentTokens supported → mapping `(user, token) → amount`. + Attacker spams swaps with dust to pollute user's claim list. +- **Impact:** Med. +- **Likelihood:** Med. +- **Mitigation:** Whitelist of paymentTokens, owner-curated; only ~3 tokens supported. + +### D5. Reentrancy lock starvation +- **Vector:** Single global `nonReentrant` lock blocks parallel ops. +- **Impact:** Low. +- **Likelihood:** Low. +- **Mitigation:** OpenZeppelin's `ReentrancyGuard` is per-function; not a real DoS. + +--- + +## E — Elevation of privilege + +### E1. Owner sets unlimited tax / fees +- **Vector:** Owner calls `setTaxBps(10_000)` (100%) — every swap fully extracted. +- **Impact:** Critical. +- **Likelihood:** Med (compromised key). +- **Mitigation:** Hard-coded `MAX_TAX_BPS = 1000` (10%). Setter rejects values >. + +### E2. Owner upgrades to malicious implementation (UUPS) +- **Vector:** Upgradeable proxy + owner = owner can swap impl to drainer. +- **Impact:** Critical. +- **Likelihood:** Low (multisig). +- **Mitigation:** + - Multisig 3-of-5 with hardware wallets. + - 48h timelock between propose and execute upgrade. + - Public announcement channel. + - `_authorizeUpgrade` audited. + +### E3. Owner drains ETH / tokens via `rescueToken` +- **Vector:** `rescueToken(any, any)` exists "to recover stuck assets". +- **Impact:** Critical. +- **Likelihood:** Med. +- **Mitigation:** Rescue function MUST blacklist protocol tokens (`paymentToken`, + bonding curve LP, registered tokens). Only "stranger" tokens recoverable. + +### E4. Privileged role inflation +- **Vector:** `addOperator` adds many EOAs; one is compromised. +- **Impact:** High. +- **Likelihood:** Med. +- **Mitigation:** Single `bondingOperator` slot, not a set. Rotation via timelock. + +### E5. Bonding contract authorized to call `credit` on registry +- **Vector:** If any other contract is granted authorized status, it can mint + pendingRewards arbitrarily. +- **Impact:** Critical. +- **Likelihood:** Low. +- **Mitigation:** `authorizedCrediter` is a single address, set once at deploy, + immutable.

Reentrant call sees `activated[victim] = false` and proceeds before outer transfer reverts. +- **Impact:** free activation. +- **Mitigation:** `nonReentrant`; CEI strictly; prefer pull-rewards (no callback to ancestors). +- **Test:** Echidna with malicious referrer contract. + +--- + +## A-06 — GWT mint inflation + +- **Maps to:** E-04, INV-G-01/02. +- **Pre-conditions:** `GWTToken.mint` reachable from any path other than `FlowProtocol` fee charge, OR fee path is duplicated. +- **Steps:** call `mint` directly, or trigger fee twice via duplicated event handler. +- **Impact:** inflated GWT → user buys 10× their entitled IL. +- **Mitigation:** single `MINTER_ROLE = FlowProtocol`; immutable; reject any other path. +- **Test:** unit — call `mint` from EOA → revert; check `G == ghost_F` after every action. + +--- + +## A-07 — Sandwich on `buy()` + +- **Maps to:** I-02, INV-B-06. +- **Pre-conditions:** price function depends on `S` (bonding curve element). +- **Steps:** + 1. Searcher sees a 50k USDT pending `buy` from victim. + 2. Searcher front-runs with own `buy` at lower price. + 3. Victim's `buy` mints at higher price. + 4. Searcher `sell`s. +- **Impact:** victim loses; pool slightly drained per cycle. +- **Mitigation:** flat per-tier price (no continuous curve), or `slippageBound` parameter on `buy`; commit-reveal for buy queue; private mempool integration (Flashbots Protect). +- **Test:** `forge test --match-test sandwich` with two-actor harness. + +--- + +## A-08 — MEV on `extendTree` payout + +- **Maps to:** I-02, D-01. +- **Pre-conditions:** payouts pushed synchronously to ancestors during `extendTree`; ancestor list inferable. +- **Steps:** searcher precomputes ancestor list, opens a position via cheap activation under that branch, becomes ancestor, captures payout share. +- **Impact:** small per-event but recurring. +- **Mitigation:** payouts are pull-based with merkle proofs of position at `extendTree` block (snapshot); flat per-level reward independent of ancestor count. +- **Test:** simulate ancestor injection across 1 block. + +--- + +## A-09 — Reentrancy on `sell` drains pool + +- **Maps to:** D-03, E-02, INV-X-02. +- **Pre-conditions:** USDT swapped/extended to a token with hooks (USDT itself has no `transfer` hook on BSC, but if migrate to USDC.e or token-with-callback this opens). Or transfer `value` to user before updating `B[u]`. +- **Steps:** + 1. Attacker calls `sell(amount)`; protocol sends USDT first. + 2. Attacker contract `tokensReceived` re-enters `sell(amount)`; `B[u]` still un-decremented. + 3. Loop until pool empty. +- **Impact:** total pool drain. +- **Mitigation:** `nonReentrant`; CEI (`_burn` → `IL` burn → `safeTransfer`); reject non-whitelisted accept tokens; SafeERC20. +- **Test:** Foundry harness with malicious ERC777-style token swapped in (negative test should fail to swap; but for safety run with custom test token). + +--- + +## A-10 — Tree payout grief (push-payment poisoning) (CRITICAL) + +- **Maps to:** D-01, INV-A-02. +- **Pre-conditions:** `_payTree` pushes USDT/$FLOW to each active ancestor synchronously. +- **Steps:** + 1. Attacker activates an account at L7 in a victim's branch. + 2. Attacker's account is a contract with `receive() { revert; }` (or `assembly { invalid() }`). + 3. Any descendant's `extendTree` reverts when the loop reaches L7 → entire tree above is starved. +- **Impact:** branch fully bricked; users cannot extend; capital trapped. +- **Mitigation:** **pull-payment only**. `_payTree` writes `pendingReward[ancestor] += share` and emits event; ancestors call `claim()` separately. Alternatively `try ... catch { skip + emit }`. +- **Test:** deploy malicious receiver, run `extendTree` from descendant, assert success and `pendingReward` accrued. + +--- + +## A-11 — Front-run referrer registration + +- **Maps to:** S-03. +- **Pre-conditions:** `referrer` need not be active at activation time. +- **Steps:** + 1. Alice signs `activate(referrer = ghost)` where `ghost` is unactivated wallet. + 2. Attacker monitors mempool, sends `activate(ghost, referrer = attacker)` with higher gas; ghost lands under attacker. + 3. Alice's tx executes; her referrer chain now flows into attacker. +- **Impact:** attacker captures Alice's upline rewards. +- **Mitigation:** `require(activated[referrer], InactiveReferrer())`; reject ghost references at activation time. +- **Test:** simulate two pending txs; assert Alice's tx reverts when ghost is unactivated. + +--- + +## A-12 — Owner backdoor: `income_limit_factor` retro-bump + +- **Maps to:** T-01, E-01. +- **Pre-conditions:** factor is mutable post-deploy without snapshot. +- **Steps:** owner (compromised key) bumps factor 10×; whale's old `IL[u]` ostensibly didn't change, but if implementation re-derives `IL` from `S * factor` views, instant exploit. +- **Impact:** silent pool drain. +- **Mitigation:** factor immutable, OR snapshot-at-buy; timelock + bound. +- **Test:** verify `IL[u]` equals sum of `(value_buy_i * factor_at_buy_i)` ignoring later factor changes. + +--- + +## A-13 — Income limit double-burn skip + +- **Maps to:** T-05, INV-IL-03. +- **Pre-conditions:** `sell` calls `safeTransfer` then `IL[u] -= burn` (broken CEI). +- **Steps:** reentrancy through transfer hook re-enters `sell` before burn applied → user sells twice while burning IL once. +- **Impact:** uncapped earnings; pool drain. +- **Mitigation:** CEI + `nonReentrant`. +- **Test:** see A-09; assert `IL[u]` decremented before transfer. + +--- + +## A-14 — Spillover O(n) DoS + +- **Maps to:** D-02, INV-T-04. +- **Pre-conditions:** `_findSpilloverSlot` is BFS over the whole subtree. +- **Steps:** + 1. Attacker fills 50k+ nodes under root. + 2. New honest user calls `activate`; BFS scan exhausts block gas. + 3. Activation perma-fails for that subtree. +- **Impact:** registration DoS; protocol unusable for a slice of users. +- **Mitigation:** maintain `nextOpenSlot[parent]` pointer (O(1) placement), or accept `parentHint` validated on-chain (`require(branches(hint) < 3 && depth(hint) < 10 && isAncestor(referrer, hint))`). +- **Test:** stateful invariant — depth grows but `activate` gas stays < 500k. + +--- + +## A-15 — Daily-limit refill replay (48h window) + +- **Maps to:** INV-DL-03. +- **Pre-conditions:** `dailyExtra` granted on sell, expires after 48h, but expiry uses `block.number` not `block.timestamp` (or vice-versa with miner manipulation). +- **Steps:** attacker sells, gains `DX`, then on day 3 abuses miner timestamp drift (≤900s on BSC) to slip `now - sellRefillTs == 47h59m59s`, gaining an extra refresh window. +- **Impact:** marginal — extra ~50 USDT sell capacity. +- **Mitigation:** use `block.timestamp` strictly; comparison `now <= sellRefillTs + 48h` is fine given miner drift bounds; document accepted ±15min drift. +- **Test:** time-warp boundary at 47h59m and 48h01m. + +--- + +## Coverage matrix + +| Scenario | THREAT_MODEL ID | INVARIANT IDs | +|----------|-----------------|---------------| +| A-01 | S-01 | INV-T-04 | +| A-02 | T-05 | INV-IL-01/06 | +| A-03 | T-02 | INV-DL-01/04 | +| A-04 | S-02 | INV-T-03 | +| A-05 | E-01, D-03 | INV-A-03 | +| A-06 | E-04 | INV-G-01/02 | +| A-07 | I-02 | INV-B-06 | +| A-08 | I-02, D-01 | — | +| A-09 | D-03, E-02 | INV-X-02 | +| A-10 | D-01 | INV-A-02 | +| A-11 | S-03 | INV-T-03 | +| A-12 | T-01, E-01 | INV-IL-06 | +| A-13 | T-05 | INV-IL-03 | +| A-14 | D-02 | INV-T-04 | +| A-15 | — | INV-DL-03 | + +All scenarios should have a dedicated test in `test/flow/attacks/`. diff --git a/audit-flow/CHECKLIST.md b/audit-flow/CHECKLIST.md new file mode 100644 index 0000000..5f1283f --- /dev/null +++ b/audit-flow/CHECKLIST.md @@ -0,0 +1,142 @@ +# $FLOW Pre-audit Checklist (dPNM model) + +Per-contract compliance gates.

Introduces a single LaunchpadFactory that clones registered templates via EIP-1167 minimal proxies. Both the existing virtuals-style bonding-curve stack and the new dPNM-style closed-system stack now deploy through the same entry point. Architecture: - LaunchpadFactory (UUPS, AccessControl) — one registry of templates keyed by bytes32 id. `launch(id, encodedParams, salt)` clones the registered implementation, low-level-calls its initSelector with the caller-supplied params, and emits Launched(id, instance, deployer). - DpnmTemplate — orchestrator. On initialize, clones Flow + GWT + Tree + FlowProtocol implementations, wires inter-contract roles, hands DEFAULT_ADMIN to the supplied admin and renounces itself. - VirtualsTemplate — orchestrator. On initialize, clones the FFactory + FRouter + Bonding trio, wires CREATOR / EXECUTOR / router roles, transfers Bonding ownership to admin. Sub-contracts converted to Initializable (clonable) with _disableInitializers in the constructor: - contracts/flow/FlowToken.sol - contracts/flow/FlowGrowToken.sol - contracts/flow/PhenomenalTree.sol - contracts/flow/FlowProtocol.sol (Bonding/FFactory/FRouter were already Initializable upstream.) Deploy script (script/deploy-bsc-testnet.ts) now stands up the factory, registers both templates, then launches \$FLOW exclusively through factory.launch("dpnm", ...). Future tokens (agentic memecoins, AI-generated contracts) just register a new template — no factory or script changes required. Tests: - test/factory/factory.test.js — 11 cases (registration, paused, unknown id, dpnm launch + activate/buy/sell, virtuals launch with wired roles, predictAddress, salt uniqueness, fee collection + underpayment revert). - test/flow/flow.js — updated to use new Cloner helper for proxy deployment; all 24 cases still passing. Helper: - contracts/dev/Cloner.sol — exposes Clones.clone for tests / scripts that need to bypass the factory pipeline.

Added DpnmV2Template + 6 sub-impls + deploy-dpnm-v2-template.ts script. Artifact: deployment-dpnm-v2-template-bsc-testnet.json (tx 0x8644…569b). Bug 2: default treeRoot was deployer.address — DPNMTree marks it placed in initialize(), so deployer's activate() call hit AlreadyPlaced. Changed both deploy-bsc-testnet.ts and deploy-dpnm-bsc-testnet.ts to default to 0x000000000000000000000000000000000000dEaD. Override via FLOW_TREE_ROOT / DPNM_TREE_ROOT env vars. Bug 3 (encoder guard): encodeInitializeParams already uses encodeAbiParameters (no selector) which is correct — LaunchpadFactory prepends initSelector via bytes.concat. Added explicit warning comment to prevent future regression.
