HyperCore 24/7: reading

One EVDY share is a claim on 4 holdings sitting in a contract on Tempo that has no owner, no pause and no upgrade path. Anyone can create a share by depositing the recipe, and any share can be redeemed for it. No issuer has stock tokens on this testnet, so the holdings are labeled mirrors: free tokens named “Tesla (Sheaf testnet mirror)” and so on, worth nothing. The dollar figure is what the same recipe would be worth in the real shares.

Shares outstanding: —— creations, — redemptions
Everything in the vault: —At the real stocks' price
Backing: —Held against owed, every component
Dollar desk: AlphaUSDTempo's own TIP-20 dollar

First, Tempo's own faucet: pathUSD pays the fees (Tempo has no gas token) and AlphaUSD pays for dollar orders.

Then mint the mirrors yourself: every one has a public faucet(), so your own wallet calls it and no key of ours is involved. Enough for two shares.

Tempo-native

A monthly plan the chain enforces

On Tempo a monthly plan is not an allowance a server promises to respect. You write the plan on chain: 10.10 AlphaUSD a run, once every 30 days, and the fewest and most shares a run may buy. Then you sign one access key that may spend 25 AlphaUSD every 30 days on two calls only, AlphaUSD.approve with the plan desk as spender and PlanDeskV3.instalment. Gas is paid in pathUSD, a dollar, because Tempo has no gas token.

The plan follows the price. Each run's fair share count must sit within 10% of what the last run filled at, so a normal monthly move doesn't stop it. It must also stay inside the hard bounds you sign, 85% to 120% of today's count, and no run's auction ever ends below that floor. A bigger move pauses the plan until you re-center it with your own key.

The keeper is the house key, and the house also fills. The keeper names each run's fair count, but the contract only accepts one within 10% of what your last run actually filled at and inside your hard bounds, so it is never the sole judge of the price. It can only run your installment, for exactly 10.10 AlphaUSD and at most once a period. It can't run early, re-center, rewrite or close the plan, or call the desk directly: the plan contract or the chain refuses. The 0.10% protocol fee goes to a separate treasury key the founder holds, not to this key.

Worst case with one filler: it can walk your price toward the floor, but every run still buys at least 85% of today's MAG8 for the same dollars, a price at most 1.18 times today's. Any other filler can only do better.

The recorded run

evm/scripts/tempo-sip-v3.mjs, against Tempo Moderato

The investor (here, the house) writes the plan
Plan #1 on PlanDeskV3: 10.10 AlphaUSD a run, each run within 10% of the last fill, never outside 0.70 to 1.50 MAG8 (wider than today's default of 85% to 120%). A 2-minute interval, so the recording shows two runs.

Run 2, re-centered on run 1's fill
After the interval the price had moved: run 2 asked 1.0701 MAG8 for the same cash, 5% more than run 1's 1.0192. The window had trailed to run 1's fill, so it ran (Recentered), and the investor received 1.0910 MAG8.

The recipe

Written once, in the constructor, with no setter. The recipe is in raw token units, so a split or a dividend that a token applies through its multiplier accrues to every share without anyone touching the vault.

Holding	Per share	Price	Value	Weight
AAPLmirror	0.00882	$335.96	$2.96	29.3%set 30.0%
AMZNmirror	0.011779	$262.46	$3.09	30.6%set 30.0%
METAmirror	0.002781	$718.43	$2.00	19.8%set 20.0%
TSLAmirror	0.005374	$382.55	$2.06	20.3%set 20.0%

Is it actually backed?

Held is the vault's balance of each token right now, from vaultBalances(). Owed is the recipe times totalSupply(). Deposits round up and redemptions round down, so held can never fall below owed.

Reading the vault…

Verify it yourself

Two reads against the public RPC, no key:

cast call 0x8EdF6718E08Bc481283D611EeaD5dBcE49336506 "totalSupply()(uint256)" --rpc-url https://rpc.moderato.tempo.xyz
cast call 0x8EdF6718E08Bc481283D611EeaD5dBcE49336506 "vaultBalances()(uint256[])" --rpc-url https://rpc.moderato.tempo.xyz

For every component, vaultBalances[i] must be at least unitsPerShare[i] × totalSupply ÷ 10^18. The recipe is in components().

The desk's book

Dollar orders on Tempo testnet (Moderato), newest first, read from getOrder(). A buyer escrows AlphaUSD and posts a Dutch auction: the shares they must receive start high and fall until a participant delivers the components in kind and collects the escrow. The shares are minted straight to the buyer, less the creator fee and the 0.10% protocol fee. The house filler is one such participant and fills at fair plus 0.15%.
