About Callstack
Your Market View, Priced Live
Callstack turns a view on the market into a price call. Say where BTC, Nvidia, gold or a meme coin will be and when. We price the chance from live market data and pay you in USDC on Solana if you're right. Put several calls on one slip and their odds multiply.

01
No leverage, no liquidations
A stack can never cost more than its stake. There is no margin to top up and nothing to get wiped out of.
02
Odds from the market, not a crowd
The chance of each call comes from the asset's live price and volatility, so the odds are there the moment you type.
03
Practice before it's real
Every wallet starts with 100 demo USDC to learn the slip. Switch to the real account when you're ready to deposit.

01 / Basics
What is Callstack?
A price-call platform on Solana. You call where an asset's price will be after a time you choose, and you're paid in USDC if you're right. Every outcome is decided by public market prices.
What is a stack?
One to 6 price calls placed together, one per board: crypto, meme coins, stocks, penny stocks, RWAs and custom pairs. The odds of every call multiply, and every call has to hit for the stack to pay. A single call is a stack on its own.
BTC▲×1.90×NVDA▼×1.40×GOLD▲×1.30=×3.4610 USDC stake → 34.58 USDC if all three hit. Example odds.
Can I try it without real money?
Yes. Every wallet gets a one-time demo account with 100 virtual USDC, running on the same live prices and odds. The demo balance can't be topped up or withdrawn. When you're ready, switch to Real in the wallet menu.
Demo 100.00Real USDC
Which wallets work?
Any Solana wallet in your browser: Phantom, Solflare or Backpack. You sign in by signing a short message, which costs nothing and moves no funds.
02 / Odds and settlement
Where do the odds come from?
From how far your target is from the live price, how long you give it and how much that kind of asset usually moves. That gives a win chance, turned into odds with a 6 percent house edge. They lock when the stack is placed.
How is a call decided?
When its time runs out the price is read once: CoinGecko for crypto and meme coins, exchange quotes for stocks and penny stocks, futures quotes for commodities. Above wins over the target, Below wins under it. Where the price went in between never counts.
What if the price moves while I build a stack?
Every call is priced again on the server the moment you place the stack. If the odds moved against you, nothing is taken and you're shown the new odds to accept or change.
Why do gold and oil need at least 4 hours?
Commodity futures quotes reach us about ten minutes late, so a short call on an RWA would be decided by a price that is already public. The shortest RWA call is 4 hours.
What if a price cannot be read?
That call is voided and drops out, and the combined odds are worked out again from the calls that are left. If nothing is left, your stake comes back.
Can I cancel a stack?
No. Once placed, a stack runs until its calls expire. Each call is settled within about a minute of its expiry.
03 / Money
How much can I stake and win?
From 1 to 1,000 USDC per stack. A stack that could pay more than 2,500 USDC can't be placed, so lower the stake or drop a call.
How do deposits and withdrawals work?
Everything is USDC on Solana. A deposit is a transfer you sign in your own wallet, credited once it confirms. Withdrawals go back in USDC to the wallet you connected. Requests are reviewed and sent by the team, usually within 24 hours.
What does it cost?
The 6 percent edge is built into the odds. We charge no deposit or withdrawal fee; you only pay Solana's network fee, a fraction of a cent.
Can I list my own token?
Soon. Custom pairs will let any Solana token with a DEX pool get its own board for a 20 USDC fee plus a pool of at least 200 USDC, which pays that pair's winners. Listings aren't open yet; follow @CallStackMaker on X for the date.
04 / $CALL and safety
What is $CALL?
Callstack's token on Solana. At launch its contract address is posted in the $CALL section of this site and on X at @CallStackMaker. Only trust the address shown here.
Will anyone from Callstack ask for my seed phrase?
Never. We will never ask for your seed phrase or private key, and signing in never needs them. Anyone who asks is not us.
