SIMD STRESS TEST. Goal: build, test and security-review a portfolio of 45 independent Solidity contracts in one Foundry project, and write a detailed analysis of each one. This is a capacity test: deliver as many contracts as you can to a high standard, in the listed order, and state clearly in the docs which ones are complete, partial or not started. Contracts (name: required behaviour): 1. LendingPool: over-collateralised lending of one ERC-20 against another, utilisation-based interest rate, liquidation with a 5% bonus. 2. Vault4626: ERC-4626 yield vault with deposit cap, withdrawal queue and rounding that always favours the vault. 3. StakingRewards: stake a token, earn a second token per second, reward rate set by owner for fixed periods. 4. Governor: token-weighted proposals with quorum 4%, voting delay 1 day, voting period 3 days. 5. Timelock: queue, execute and cancel calls after a minimum 2-day delay, admin handover in two steps. 6. MultiSig: M-of-N owners, submit/confirm/revoke/execute, owner add/remove only via the multisig itself. 7. DutchAuction: price falls linearly from start to floor over a set time, first buyer at current price wins, refunds excess ETH. 8. NFTMarketplace: list ERC-721 for ETH, buy, cancel, 2.5% fee to treasury, pull-payment withdrawals. 9. Vesting: linear vesting with cliff per beneficiary, revocable by owner with unvested tokens returned. 10. Escrow: buyer deposits, seller delivers, buyer releases or arbiter resolves a dispute, timeout refund. 11. Raffle: ticket sales in ETH, winner chosen from a commit-reveal seed supplied by the operator, prize claim. 12. TokenBridgeLock: lock tokens with a nonce and emit an event; unlock only with a signature from a configured relayer set (no real bridge). 13. PriceOracleAdapter: wraps a Chainlink-style feed, rejects stale (>1h) or non-positive answers, exposes 18-decimal price. 14. ConstantProductAMM: x*y=k pair with 0.3% fee, add/remove liquidity with LP shares, minimum liquidity burn. 15. FlashLender: ERC-3156 flash loans of a held token with a 0.09% fee, reentrancy guarded. 16. InsurancePool: members pay premiums into a pool, owner-approved claims paid out up to coverage, cooldown on withdrawals. 17. Crowdfund: goal and deadline, pledges refundable if goal missed, creator claims if met. 18. DAOTreasury: holds ETH and ERC-20, spending only through the Governor via the Timelock. 19. Subscription: monthly subscriptions paid in an ERC-20, keeper-triggered renewals, cancel anytime. 20. PerpetualsLite: single-market isolated-margin perps with funding rate from the oracle adapter, liquidation at 80% margin used. 21. StableSwap2: two-stablecoin curve-style pool with amplification coefficient and 0.04% fee. 22. RevenueSplitter: splits incoming ETH and ERC-20 between payees by shares, pull-based release. 23. Allowlist721: ERC-721 mint gated by a Merkle allowlist, max per wallet, owner can reveal base URI once. 24. RateLimitedMinter: role-based ERC-20 minter with a per-day mint cap per minter. 25. EmergencyPausableRegistry: registry of addresses to metadata with guardian pause, owner unpause, events on every change. 26. SoulboundBadge: non-transferable ERC-721 badges issued and revoked by an issuer role. 27. Permit2612Token: ERC-20 with EIP-2612 permit, owner-only mint up to the cap. Token name: SIMD Stress Token. Symbol: SST. Total supply cap: 1,000,000 SST with 18 decimals, none minted at deploy. 28. BatchAirdrop: Merkle-proof airdrop claims with a deadline after which the owner can sweep unclaimed tokens. 29. DCAVault: users deposit a stablecoin and a keeper swaps a fixed amount into ETH through the AMM each day. 30. LimitOrderBook: on-chain limit orders for one token pair, partial fills, cancel and expiry. 31. Bonding curve sale: linear bonding-curve token sale with buy and sell back to the curve and a 1% spread. 32. ReferralRewards: tracks referrers on first deposit and pays a 1% referral reward from a funded pool. 33. SavingsLock: lock ETH until a chosen date, early exit with a 10% penalty sent to a charity address. 34. VotingEscrow: lock tokens for 1 week to 4 years for decaying voting power, extend lock or amount. 35. GaugeController: VotingEscrow holders vote weekly on how rewards split between gauges. 36. NameRegistry: first-come name registration for a yearly fee in ETH, renew, transfer, expiry with grace period. 37. Tipping: send ETH tips with a message to a creator, creator withdraws, top-tipper leaderboard of 10. 38. Lottery commit-reveal: players commit hashes, then reveal; the XOR of revealed secrets picks the winner, non-revealers forfeit. 39. WrappedETH: minimal WETH: deposit, withdraw, ERC-20 transfers. 40. CreditDelegation: a lender delegates borrowing power in the LendingPool to a trusted borrower with a limit. 41. StreamingPayments: sender streams an ERC-20 to a recipient per second between start and end, recipient withdraws accrued, sender cancels and gets the rest. 42. BountyBoard: post bounties in ETH, hunters submit a hash of their work, poster accepts one and pays, unclaimed bounties refundable after expiry. 43. Whitelist sale: fixed-price ERC-20 sale for allowlisted buyers with per-wallet cap, hard cap and owner withdrawal after the sale ends. 44. ProofOfAttendance: event organiser creates events; attendees claim one non-transferable badge per event with an organiser signature. 45. KeeperRegistry: keepers register with a bond, perform upkeep for a fee, and lose part of the bond if a missed upkeep is reported and confirmed by the owner. Rules for every contract: - Solidity ^0.8.24, OpenZeppelin where it helps, NatSpec on every external function, custom errors, events for every state change. - Checks-effects-interactions, reentrancy guards where value moves, no tx.origin, no unbounded loops over user-controlled arrays. - Owner or role powers kept minimal and listed in the docs. - Foundry tests: happy paths, reverts, and at least one fuzz or invariant test per contract. - Keep every contract independent unless the spec names another contract; where it does, use an interface so each file compiles alone. - Use safe ERC-20 transfers, handle fee-on-transfer tokens by measuring balances, and never assume 18 decimals. - Timestamps and block numbers may be manipulated slightly by validators; design deadlines with that in mind. - Prefer pull payments over pushing ETH to arbitrary addresses. - Every admin action emits an event and is listed in the docs with who can call it. Analysis depth for docs/ANALYSIS.md, per contract (aim for 300 to 600 words each): - A one-paragraph plain-English description a non-developer can follow. - A table of roles and the functions each role can call. - The lifecycle: states, transitions and what triggers each one. - At least five concrete risks with a short attack or failure scenario each, the impact, and how the code prevents or limits it. - Gas notes: the most expensive function and why. - Test coverage: which behaviours the tests prove, and which are not covered. - Status: complete, partial (say what is missing) or not started. Order of work: follow the list. If time or budget runs out, finish the current contract cleanly, then write the analysis and summary for everything done so far rather than leaving half-written files. Required files: - src/<Name>.sol for each contract. - test/<Name>.t.sol for each contract. - docs/ANALYSIS.md with one section per contract: purpose, roles and permissions, state machine, trust assumptions, main risks (economic, access control, oracle, reentrancy, rounding, griefing), mitigations, test coverage summary, and a status line (complete / partial / not started). - docs/SUMMARY.md: a table of all contracts with status, lines of code, number of tests, and the top risk of each. Do not deploy anything. Do not add a front end.
