Step 1 · creator

Start a market-specific window.

Test assets only

Choose buy or sell, set a limit inside the fixed $19.50–$20.50 demo grid, and choose the cutoff. CallWindow creates the selected market's Devnet auction account first, then you fund its opening order. The shareable URL appears only after both transactions finalize.

Step 2 · joiner

Join a shared market window.

Check the selected market and named test mint, connect Phantom or Solflare on Devnet, then fund one limit order before cutoff. After the window closes, return here to claim a fill or refund.

Joining from a shared URL?

The server rechecks the official market mapping, program owner, exact test mints, state, and deployed bounds before showing actions. No real PreStocks token enters the auction.

The $19.50–$20.50 grid is illustrative test pricing. It does not represent the selected PreStocks market price, fillability, or execution.

Your Devnet wallet

Prepare and sign

No mainnet tx

CallWindow signs only Solana Devnet test transactions. Before each action, review the named test assets, amount, cutoff, rent, and fees. A PreStocks mainnet transaction is never submitted.

Detecting Phantom and Solflare…

No wallet connected.

Devnet SOL—

Selected test shares—

DEMO-USD—

Need this market's test assets?

Claim 10 selected test shares and 50 DEMO-USD up to two times per wallet, within the 50-claim global cap. If this window has already closed, the claim prepares the same market's next Devnet window. These tokens have no issuer backing or monetary value. You still need Devnet SOL for rent and fees.
