Basket Protocol vault: an index vault for Stock Tokens on Robinhood Chain (chain id 4663). Contracts only: no launch token, pool or website. BASK is the vault's own ERC-20 share (18 decimals). Write "Stock Tokens" (never "tokenized ..."); no Robinhood name, logo or ticker beyond the chain's name. Token name: Basket Token symbol: BASK Total supply: 0 at deployment, no cap: deposit mints, redeem burns BUILD RULES - Simplest code that satisfies this text: add no feature, role, setting or safeguard. - solc 0.8.26, optimizer on, 200 runs, evm cancun, bytecode_hash none; custom errors. - If BaskVault exceeds 24,000 bytes of runtime, move views into BaskLens(address vault = $contract:BaskVault); never drop a check. - Constructors call no other contract. Time is block.timestamp, never block.number. - No proxy, delegatecall, selfdestruct, rescue or sweep. User-facing state changes are nonReentrant and emit events. MANIFEST 1. BaskVault(address owner_, address guardian_): owner_ = 0x30B57ECf51D19ABcED7F6f70974e6fBb6f3b9Da3, guardian_ = 0x5ed39AF86f2C00ad99913B5d727bD68f2A904B68, written as these literals. Reverts if either is zero or they are equal. STOCK_FACTORY = 0x4783C67b63dE2B358Ac5951a7D41F47A38F3C046 is a source constant. Outside contracts (only on chain 4663: tests use mocks under test/ with exactly these functions; no fork tests, no vm.env): - Stock Token: ERC-20, 18 decimals, uid() returns bytes32, oraclePaused() returns bool. Its issuer can pause it, block or burn any holder and upgrade it. - STOCK_FACTORY.tokenAddress(bytes32 uid) returns address. - Feed: Chainlink proxy: decimals() is 8, aggregator() returns address, latestRoundData(); answer = USD per whole token. ASSETS: a list of (token, feed, open, minAnswer, maxAnswer, listedAt), at most 64, empty at deployment, never removed. managed[token] is the accounting balance: value never uses balanceOf and tokens sent directly are ignored. Listing checks, at proposal and again at execution: token not listed; token.decimals() == 18; STOCK_FACTORY.tokenAddress(token.uid()) == token; feed.decimals() == 8; feed.aggregator() != 0; feed not used by another asset; answer > 0. On listing open = true, minAnswer = answer / 4, maxAnswer = answer * 4. Genesis: until the owner calls finalizeGenesis() (once, needs 3 or more assets), proposeAsset(token, feed) and proposeAssets(tokens[], feeds[]) list at once and deposits are impossible. Deposits open 72 hours after finalizeGenesis(). Except listing in genesis, these owner actions are always proposals: list an asset; replace an asset's feed (feed checks and new answer inside the band, both times); re-centre a band on the answer at execution, under 26 hours old; reopen an asset (cancelled by any later close); replace the guardian; raise NAV_CAP. A proposal waits 7 days, then anyone may execute it; it lapses 7 days later; the owner may cancel it, as may the guardian unless it replaces the guardian. One listing or feed replacement executes per 24 hours. An asset listed after genesis is on probation for 30 days. PRICE is valid only if the feed read succeeds, answer > 0, minAnswer <= answer <= maxAnswer, updatedAt <= now, now - updatedAt <= 26 hours, and token.oraclePaused() returns false. value(amount) = amount * answer / 1e8, rounded down (USD, 18 decimals). USD limits below are dollars times 1e18. deposit(token, amount, receiver, minSharesOut, deadline) requires: - deposits open and not paused; token listed and open, vault balance >= totalOwed[token]; receiver not the vault; - market gate: (now / 86400 + 4) % 7 is 1 to 5 (0 = Sunday) and 55800 <= now % 86400 < 70200 (Mon-Fri 15:30-19:30 UTC all year); and 3 or more listed assets have feed updatedAt within the last 4 hours; - a valid price for this token and every asset with managed > 0; no asset short or unreadable (see LOSSES). Pull the tokens; the vault balance must rise by exactly amount. NAV = sum of value(managed) before the deposit; v = value(amount). gross = v if totalSupply is 0, else v * totalSupply / NAV rounded down (revert if NAV is 0). fee = gross * 50 / 10000, rounded up: minted to feeRecipient, or not minted while that is unset. The receiver gets gross - fee; on the first deposit 1e15 of that goes to address(0xdEaD) instead. The receiver's amount must be > 0 and >= minSharesOut. Caps after the deposit, with NAV2 = NAV + v: - NAV2 <= NAV_CAP (starts 1,000,000; the owner lowers it at once, raises it by proposal, never above 10,000,000,000); - value(managed[token]) <= max(NAV2 * 5 / 100, 25,000), or max(NAV2 / 100, 5,000) on probation; - bucket <= max(NAV2 * 25 / 100, 100,000): one bucket for all deposits, which first decays (bucket -= bucket * elapsed / 86400, floor 0), then adds v. redeem(shares, minAmountsOut[], deadline) reads no price, ignores every pause and gate, and never reverts because of an asset. fee = shares * 50 / 10000 rounded up: transferred to feeRecipient, or burned with the rest while unset. net = shares - fee is burned. Per asset: available = balanceOf(vault) - totalOwed[token], floor 0 (low-level static call, 50,000 gas, copying 32 bytes; any other outcome: unreadable, available = managed); leg = min(managed, available) * net / totalSupplyBeforeBurn, rounded down; require leg >= minAmountsOut[i] (missing entry = 0); managed -= leg. Each leg is paid to msg.sender by an external function only the vault itself may call, given 250,000 gas, which reverts unless the transfer succeeds, returns nothing or true, and the vault balance falls by exactly leg. If it fails, owed[msg.sender][token] and totalOwed[token] grow by leg. claim(token, to) pays min(caller's owed, vault balance) by the same function with no gas limit. LOSSES. An asset is short when available < managed. Nothing lowers managed automatically. flagDeficit(token), by anyone, records shortfall and time if larger than recorded. recognizeLoss(token), by anyone 7 days or more later, lowers managed by min(recorded, current shortfall) and clears the record. A deposit clears every record. Who can call what: - Owner (two-step transfer, no renounce): the proposals; cancel; close an asset to deposits at once; pause and unpause deposits; lower NAV_CAP; setFeeRecipient(address) once, not zero or the vault, final. The vault never calls feeRecipient. - Guardian: pause deposits, close an asset, cancel proposals as stated. - Nobody can move assets, block redeem or claim, mint outside deposit, change a fee or upgrade. Upgrades and pausing: none except the deposit pause and per-asset close. Numbers the contracts enforce: all constants except NAV_CAP. VIEWS: all assets with feed, answer, updatedAt, band, open, probation, managed, short, totalOwed; previewDeposit; previewRedeem; navPerShare; depositStatus(token): a reason code and the asset at fault, as in deposit's revert; pending proposals. REVIEW. Accepted design, note only, add no mechanism: (1) deposit-then-redeem profit when a feed lags more than the 1% round-trip fee; (2) the owner is trusted to pair each token with its true feed; (3) an untransferable asset keeps its feed value until deposits are paused. MUST ATTACK: a paused, blocked or upgraded token during redeem (with 64 assets in any state it stays under 28,000,000 gas); role abuse; any way a role blocks redeem.
