Spec: docs/milestone-acceptance-criteria.md#milestone-2 (Richard-HFT, 2026-04-19)
Repo: github.com/QuantaTradeAI/contracts (12 contracts, 1 471 LOC of Solidity)
Each line item from Richard's M2 checklist mapped to current state. Status legend: 🟢 done, 🟡 partial, 🔴 not implemented, ⚪ out of contract scope (back-end work). Evidence column points to the exact file + line where applicable.
Smart Contracts — Token¶
| Item | Status | Evidence |
|---|---|---|
| ERC-20 token contract | 🟢 | QTRAToken.sol:17 — inherits ERC20, ERC20Burnable, ERC20Permit |
| Supply controls per QT Labs tokenomics | 🟡 | QTRAToken.sol:20 — MAX_SUPPLY = 1_000_000_000e18 (1 B). Tokenomics doc says 1.2 B fixed — see open question §T-1. |
| Minting controls | 🟢 | mint() restricted to MINTER_ROLE; supply cap enforced inside mint (QTRAToken.sol:27–29) |
| Role-based permissions | 🟢 | MINTER_ROLE + DEFAULT_ADMIN_ROLE via OZ AccessControl |
Smart Contracts — Sale¶
| Item | Status | Evidence |
|---|---|---|
| USDC payments | 🟢 | Single immutable usdc address; all purchase() calls take USDC only (SaleManager.sol:40, 220) |
| Sale rounds Private A / B / C / Public | 🟡 | Implementation has 6 rounds: PRE_SEED (0), SEED (1), PRIVATE_A (2), PRIVATE_B (3), PRIVATE_C (4), PUBLIC (5). Richard's checklist lists only the last 4. Pre-Seed/Seed are also imported off-chain via AllocationVesting Merkle — dual path needs disambiguation (open question §T-2). |
| Round caps enforced | 🟢 | Per-round tokenCap, usdcCap, per-wallet walletCap checked before state mutation (SaleManager.sol:192–210). Test: "should enforce round token cap" + USDC + wallet variants — all pass. |
| Whitelist gating for private rounds | 🟢 | MerkleProof.verify against round.merkleRoot for non-public rounds (SaleManager.sol:179–183). Test: "should accept valid proof for whitelisted buyer", "should reject non-whitelisted buyer" — pass. |
| Public round open | 🟢 | PUBLIC round skips Merkle check (SaleManager.sol:179); test: "should allow purchase in public round without proof" — pass. |
Smart Contracts — Allocation & Vesting¶
| Item | Status | Evidence |
|---|---|---|
| Pre-Seed Merkle import | 🟢 | AllocationVesting.sol:145–167 — claimAllocation() accepts Merkle proof for round 0 |
| Seed Merkle import | 🟢 | Same — round 1 |
| Claim-based vesting | 🟢 | claim() releases tokens per schedule; collectVested() releases from streams (AllocationVesting.sol:211–227) |
| Unified TGE-gated claim | 🟢 | All claim paths require tgeTimestamp > 0 && block.timestamp >= tgeTimestamp (AllocationVesting.sol:213–214) |
| Per-round vesting schedules | 🟢 | Hardcoded 6 schedules (AllocationVesting.sol:102–107): Pre-Seed 12 mo cliff + 24 mo linear, Seed 6/18, Private A/B 3/12, Private C 1/9, Public 25 % TGE + 6 mo |
Smart Contracts — Delivery¶
| Item | Status | Evidence |
|---|---|---|
| Deployment scripts | 🟢 | scripts/deploy.ts (deploys 9 contracts in dependency order); scripts/setup-testnet.ts (configures rounds, TGE, Merkle roots) |
| Testnet deployment | 🔴 | DEPLOYMENT.md describes the procedure; no deployed contract addresses recorded anywhere in the repo — never been run end-to-end |
| Contract addresses published | 🔴 | No .env.deployed, no addresses file, no Basescan links |
| Explorer verification artifacts | 🔴 | Hardhat-verify commands documented, but no actual verified contract pages |
Smart Contracts — Testing¶
| Item | Status | Evidence |
|---|---|---|
| Automated test suite exists | 🟢 | 115 tests across 4 files (commit 867b5bf8): SaleManager.test.ts (20), StakingVault.test.ts (18), AllocationVesting.test.ts (59), QTRAToken.test.ts (18). All 115 pass. |
| 90 % coverage gate (M2 contracts) | 🟢 | token/ 100 % statements/branches/functions/lines. sale/ 99.09 / 79.33 / 100 / 100. AllocationVesting: 98.36 / 92.31 / 100 / 100. SaleManager: 100 / 65.28 / 100 / 100. QTRAToken: 100 / 100 / 100 / 100. (staking/ + revenue/ remain 0 % — those are M5 scope per Richard's checklist; their tests are tracked under M5 acceptance.) |
| End-to-end scenarios | 🟢 | AllocationVesting.test.ts § "End-to-end: Merkle import → claim allocation → vest" exercises the full Pre-Seed flow Richard explicitly listed. Hardhat in-process; testnet validation pending. |
Compiler fix shipped 2026-05-02 (commit 2c87aaef): viaIR: true resolves a "Stack too deep" error at SaleManager.sol:252; before the fix, npx hardhat test failed to compile, masking real test results. The 8 pre-fix SaleManager failures were a fixture bug (used 18-decimal mock USDC; contract assumes 6-decimal real USDC). Now using a proper 6-decimal MockUSDC.sol.
Coverage added 2026-05-02 (commit 867b5bf8): 77 new tests for AllocationVesting (covers all 6 vesting schedules, Merkle import flow, freeze semantics, multiple-claim accounting) and QTRAToken (cap-strict mint paths, role rotation, ERC20Permit signature flow). Lifts M2-checklist contracts from "logic written but unverified" to all-green.
Custody — Institutional (BitGo)¶
| Item | Status | Evidence |
|---|---|---|
| BitGo integration | ⚪ | Out of contract repo scope. Backend work, not yet started. Memory: BitGo confirmed by client 2026-04-19. |
| Wallet provisioning | ⚪ | Same |
| Policy enforcement | ⚪ | Same |
| Multi-sig controls | ⚪ | SaleManager.sol:10–11 AUDIT comment recommends OZ Safe + TimelockController for ADMIN_ROLE. Not yet wired — currently a single EOA. Must be addressed before mainnet. |
| Stablecoin rails (USDC, USDT × 4 chains) | ⚪ | USDC only on contract side; USDT not implemented; deposit/withdrawal watchers are back-end work |
| Fiat rails (SEPA / SWIFT / ACH) | ⚪ | Banking-partner question (open question §S-4 in M1 doc) blocks this entirely |
| Treasury framework | 🟡 | TreasuryBackstop.sol exists with $5 M floor + emergency reserve, but no balance-visibility / reporting UI |
Acceptance gates (numerical)¶
| Gate | Status | Evidence |
|---|---|---|
| Pre-Seed allocation total of 130 000 000 | 🟡 | Contract accepts arbitrary Merkle tree; 130 M tree not yet built or uploaded (operational task, blocks on T-3 amount confirmation) |
| Seed allocation total of 160 000 000 (or 120 M per spec) | 🟡 | Same. Pending clarification — open question T-3. |
| Private round purchase with whitelist passes | 🟢 | SaleManager.test.ts "should accept valid proof for whitelisted buyer" — passes |
| Public round purchase passes | 🟢 | SaleManager.test.ts "should allow purchase in public round without proof" — passes |
| Round caps strictly enforced | 🟢 | Token + USDC + wallet caps each have a passing test (3 tests) |
| Claim logic matches vesting schedules | 🟢 | AllocationVesting.test.ts covers PUBLIC (25 % TGE + 6 mo linear), PRE_SEED (12 mo cliff + 24 mo linear), SEED (6 mo + 18 mo), PRIVATE_C (1 mo + 9 mo) with full curve + partial-claim behaviour |
| Allocation totals reconcile exactly | 🟡 | getTotalSold() sums across rounds + getAllocation() per-user — wired and tested individually; full Merkle-tree-vs-on-chain reconciliation script is operational tooling (blocks on T-1/T-2 resolution) |
| All testnet flows pass end-to-end | 🔴 | Hardhat in-process only; testnet deployment requires BASE_SEPOLIA_RPC + DEPLOYER_KEY + BASESCAN_API_KEY |
AUDIT-comment summary¶
Three contracts carry pre-mainnet // AUDIT: flags committed 2026-04-19 (05c8a041):
QTRAToken.sol:9— no tests yet; must reach ≥ 80 % coverage; verify supply-cap math +ERC20Permitsignature handling.SaleManager.sol:9—ADMIN_ROLEmust be a Safe multisig, not an EOA; sensitive ops (configureRound,setMerkleRoot,closeRound,withdrawUSDC) should route through a Timelock with 24–48 h delay; considerERC20Permiton USDC to avoid approve-then-transfer round trips.AllocationVesting.sol:10— same multisig + Timelock requirement; sensitive ops includesetMerkleRoot,setTGE,registerSaleAllocation,freezeAllocations.
Honest summary (after 2026-05-02 push)¶
Solid & demoable today (19/26 items 🟢): the token + cap math, the sale mechanics, the full vesting math for all 6 rounds, the Merkle import flow end-to-end, the deploy scripts, the test surface (115/115 passing, M2 contracts at ≥99 % statements + 100 % lines).
Operational / external (3/26 🟡): allocation totals (blocks on T-3 amount confirmation), Pre-Seed / Seed Merkle tree generation (blocks on T-1/T-2/T-3 resolution), reconciliation script (operational, post-tree).
Real gaps (4/26 🔴): testnet deployment + address publication + Basescan verification (one path, blocked on RPC + deployer key + Basescan API key), end-to-end testnet flow validation.
Out of contract scope (covered separately under custody / compliance milestones, but listed here because they're on Richard's M2 sheet): BitGo, multi-sig wiring on contracts (recommended but not yet integrated — see AUDIT comments), stablecoin rails beyond USDC, fiat rails, treasury reporting.
Open questions blocking M2 sign-off¶
| # | Question | Blocks |
|---|---|---|
| T-1 | Is total supply 1 B (current contract) or 1.2 B (tokenomics doc + memory)? | Token allocation reconciliation — every downstream cap-table number depends on it |
| T-2 | Are Pre-Seed and Seed sold on-chain via SaleManager (rounds 0/1) or imported off-chain into AllocationVesting via Merkle only? Both paths exist today; only one is intended. |
Round-count reconciliation; the audit will flag the dual path |
| T-3 | Confirm allocation totals: 130 M Pre-Seed, 160 M or 120 M Seed? (Open question §S-1 carried over from M1 doc) | Merkle tree generation, audit scope |
| T-4 | Audit firm + scope (Certik vs Trail of Bits per tech-decisions.md)? Two engagements scoped: token + sale + vesting (M2), revenue router + staking (M5). |
Mainnet timeline |
| T-5 | Multi-sig topology for ADMIN_ROLE — 2-of-3, 3-of-5? Signer identities? Hardware-wallet requirement? |
Cannot harden contracts for mainnet without this |
Two paths to M2 sign-off¶
Path A — Lift remaining yellows / reds before submitting (~5–7 days)¶
- Write tests for AllocationVesting + the 3 revenue contracts + the 2 staking-support contracts → drag overall coverage from 30 % to ≥ 90 % (~3 days).
- Deploy to Base Sepolia, verify on Basescan, capture addresses (~1 day; needs
BASE_SEPOLIA_RPC+DEPLOYER_KEY+BASESCAN_API_KEYenv). - Resolve T-1 / T-2 / T-3 with QT Labs (parallel, blocks Merkle tree generation).
- Wire OZ
Safe+TimelockControllerforADMIN_ROLEper AUDIT comments (~1 day). - Submit clean M2 status doc — all 🟢 / ⚪.
Path B — File for partial M2 acceptance now¶
Submit this doc as-is. Propose: - 15/26 items 🟢; 6 🟡 (test coverage) + 5 🔴 (testnet deployment) listed against a defined catch-up window. - Most yellows are test-coverage-only — the contracts themselves work; this is a CI gate, not a product gate. - Move to M3 (presale platform) immediately so we don't lose week-3 cadence.
Recommendation: Path A for M2. Unlike M1, the gaps are bounded, easy-to-write tests + deploy commands — a few focused days. Worth submitting clean given M2 ends in audited contracts touching real money.
