HyperCore 24/7: reading
One EVDY share is a claim on 4 holdings sitting in a contract on Base 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
- sUSDA labeled test dollar
First, a drip of test ETH for gas, if the wallet is nearly empty.
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, plus 50 sUSD.
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.
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.

Verify it yourself
Two reads against the public RPC, no key:
cast call 0xe843E1Cc12aEb0824a054D2101333da12b4B3456 "totalSupply()(uint256)" --rpc-url https://sepolia.base.org
cast call 0xe843E1Cc12aEb0824a054D2101333da12b4B3456 "vaultBalances()(uint256[])" --rpc-url https://sepolia.base.orgFor 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 Base Sepolia, newest first, read from getOrder(). A buyer escrows sUSD; any participant who delivers the components in kind collects it, and the shares are minted straight to the buyer. The house filler is one such participant.

Priced around the clock
The stock exchanges close; HyperCore's stock perpetuals do not. This prices the same recipe from trade.xyz's oracle on Hyperliquid testnet, read through HyperEVM's oraclePx precompile with a plain eth_call, no gas and no key. It is a reading, not a deployment: nothing of Sheaf runs on Hyperliquid yet.
