Frequently asked questions

Everything you might want to know about how ToldYou works. Still got questions? Reach out via the channels in the footer.

What is ToldYou?

ToldYou is a decentralized prediction market platform on Solana. Users create yes/no markets on any topic and trade shares whose price reflects the probability the crowd assigns to the outcome. When a market resolves, winning shares pay out 1 USDC each.

How does pricing work?

Each market uses an LMSR (Logarithmic Market Scoring Rule) automated market maker. The price of a YES share is always between 0 and 1 USDC and represents the implied probability of YES resolving true. As people buy YES, the YES price goes up and NO goes down, and vice versa.

How do markets resolve?

Most markets resolve through UMA's Optimistic Oracle on Polygon. Anyone can submit an answer, which becomes binding after a challenge window unless someone disputes it. Disputed answers go to UMA's Data Verification Mechanism for tokenholder vote.

What does it cost to trade?

There's a small per-trade fee (~1%) paid in USDC, plus standard Solana network fees (a fraction of a cent). Market creators set a liquidity budget when creating a market — that's their cost; takers pay only the trade fee + slippage.

Can I create my own market?

Yes. Click "Create" in the nav, fill in the question, description, resolution date, category, and image, and seed it with USDC liquidity. The market is live immediately and starts at 50/50.

What wallets are supported?

We use Privy for auth, which supports email/social login (with an embedded wallet auto-created), plus connecting external wallets — Phantom, Solflare, MetaMask, and any other major Solana or Ethereum wallet.

Is this real money?

Yes. ToldYou markets settle in USDC on Solana mainnet. Markets resolve to either 1 USDC or 0 USDC per share based on outcome. During the alpha period some markets may be on Solana devnet for testing — check the market detail page.

What's the alpha access key?

ToldYou is in private alpha. We're whitelisting users individually so we can iron out edge cases before the broader launch. If you have a key, enter it on the access page and you're in until further notice.

How do I withdraw winnings?

When a market resolves, your winning shares become claimable on the market page. Click "Redeem winnings" — you sign one transaction and the USDC lands in your wallet immediately.
