One share
—
— today
One IDX share is a claim on 3 holdings sitting in a vault this program controls. The program releases them only against a redeemed share, and a share can always be redeemed; the tokens’ issuers keep their own powers over them, as the risks explain.
No price for SPY, QQQ, GLD, so the value of a share is left blank rather than computed from part of the basket.
Pay in dollars. Any filler can deliver the stocks, the auction caps what you pay at the floor you set, and the vault still receives the real components.
Prediction market
A basket's recipe is a public account, so a bet on it settles from a published number at two week-ending US closes, with every input listed so anyone can recompute it. Sheaf writes the question and the rule. Panta runs the market on Solana, priced on a bonding curve and paid in USDC.
Powered by PantaThe question
Will Index of indices (IDX) beat SPY this week?
Resolves YES if one IDX share's navPerShare.listed rose more than SPY's adjusted close between two week-ending NYSE closes (normally Friday 16:00 New York). Trading closes at the first of them, before any of the week is known. Both are read from /api/nav/EjoW…vghE?at=<close>, the market's first source of truth.

The weight on the right drifts as prices move. To change the recipe, create a new basket.

Held is what the vault contains right now. Owed is what every outstanding share can claim. Deposits round up and redemptions round down, so held can only ever be at or above owed, and the difference is rounding dust that stays with the remaining holders.
Reading the vault…
Two kinds of read, both against the public RPC, no key. First, how many shares exist:
curl -s https://api.devnet.solana.com -X POST -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"getTokenSupply","params":["EuFqn7ysdBKqVHSUBz73Hs11T5HtmtihCaUaghyU8LjM"]}'Then what each vault holds:

If that holds, every share is backed. The program cannot make it false: deposits round up, redemptions round down, and no instruction moves anything out of a vault except a redemption.
Every creation, redemption, dollar order and plan run since the basket was made, decoded from the program’s own events. The full ledger across every basket is on one page.
Reading the transactions…
Creating shares means handing the vault the components themselves, which is what lets the program refuse to trust a price. Somebody holding only dollars has to buy those components first, so here is what that costs right now, priced through the routes that actually exist on mainnet.
One component has no mainnet price, so there is nothing honest to quote.
Prices come from Solana mainnet, balances from the program itself. The arithmetic behind both is written out in full.
