It's a prediction market: you trade the outcomes of real events. Each market is a question with two answers, Yes and No. You buy a share in the outcome you think is right, and the share price is the market's probability: 63¢ means a 63% probability. You trade with other participants, not against the platform — we are not your counterparty and have no interest in you losing.

The minimum trade is $1. You can top up any amount — there's no lower limit at all, even a few cents are credited. There's no upper limit either.

  • —minimum trade — $1
  • —minimum deposit — any amount, no threshold
  • —no upper limit

No. The wallet is created automatically in the background at signup — you install nothing. No extensions, no network selection, no buying gas: sign in by email, Google or Telegram, and from there it works like a normal site.

You pay only on market trades: 1% to the platform plus a liquidity fee. Deposits, withdrawals, winnings and limit orders are free.

  • —Limit orders pay neither the platform fee nor the liquidity fee — zero.
  • —The liquidity fee on market orders goes not to us but to the liquidity providers of a third-party protocol. It depends on the market category and the share price; geopolitics markets have none.
  • —You don't pay network gas. The minimum trade is $1.

Only market orders pay it — whoever takes liquidity from the order book. Formula: category rate × price × (1 − price) × number of shares. In dollars it peaks at a price of 50¢ and decreases toward the edges.

Example: a market buy of 100 shares at 50¢ in a crypto market ($50) — liquidity fee $1.75 plus platform fee $0.50, $2.25 in total. The same purchase as a limit order — $0.

Top up in USDC on the Polygon network — any amount at all, with no lower threshold. The balance is always counted in dollars (USDC is pegged 1:1 to the dollar), so the rate doesn’t “drift” between top-up and trade.

The “Withdraw” button in the wallet, the amount, the address — that’s it. You can withdraw any amount, even $0.10. Withdrawal is absolutely free: neither the platform nor even the network takes anything — we pay the gas for the transaction.

  • —withdraw any amount — even $0.10
  • —platform withdrawal fee — 0%
  • —network fee — 0%, we pay the gas
  • —no limits or “risk-department reviews”
The transaction leaves your address and is confirmed by the network, not a support agent — it physically cannot be “put on hold”.

The markets are connected to a global prediction network with one of the world’s largest on-chain order books. Thanks to this, even a fresh market has someone to trade with, and the price reflects the opinion of thousands of participants worldwide, not a platform’s “back room”. Orders and trades execute in smart contracts on the Polygon blockchain.

The wallet is created non-custodially using secure embedded-wallet technology. The private key is split into parts and is never assembled in full — neither on our servers nor by any single participant. The balance is managed directly through smart contracts on the Polygon network: decentralized, with no “manual mode” on our side.

  • —the key is split and never assembled anywhere
  • —all operations are in smart contracts, on-chain
  • —the platform has no access to your funds

The key is yours, and only you can see it — and only if you need to. At any time you can export the private key (or seed phrase) and manage the wallet anywhere. We never see the full key — by the design of the technology, it’s impossible.

Your money stays with you. Funds sit not in a company account but at your own address on the blockchain. Even if the site disappears: you export the private key, import the wallet into MetaMask or any Web3 wallet on the Polygon network — and fully control the funds. Markets and settlement live in smart contracts, not on our servers, so they keep working without us.

  • —funds — at your on-chain address, not a company
  • —the private key is exported in one click
  • —the wallet opens in any Web3 wallet (Polygon network)
  • —smart contracts work even if the site is gone

Yes. Your wallet is tied to an account: sign in by email, Google or Telegram. You don’t need to memorize a seed phrase — access is recovered through your linked sign-in methods. And if you want full “crypto-style” control, you can export the key and save the phrase yourself at any time.

Link a second sign-in method in advance — it’s the most common cause of slow recovery.

No. Technically we have no such access: there’s no “freeze” button, no risk department, no withdrawal limits. As long as you have access to your account (or the exported key) you have access to the money, and no one, including us, can prevent it.

Everything is verifiable on the blockchain, not on our word. Any trade, payout and market settlement — including our fee — can be seen in a public explorer. Below are direct links to the contracts and to the wallet-protection technology, so you can check it yourself.

The outcome is decided not by the platform but by a decentralized oracle. Each market publishes in advance its exact wording and data source (an official site, report or exchange quotes). After the event the result is proposed to the oracle, anyone can dispute it, and the dispute is resolved by economic incentives on-chain. The result is locked in a smart contract.

  • —the wording and source are visible before the trade
  • —the result is proposed and checked by a decentralized oracle
  • —anyone can dispute a wrong outcome
  • —the result is locked in the contract — can’t be rewritten later

Each share of the correct outcome settles at $1, of the wrong one at $0. Buy 100 shares at 63¢ for $63 — on the right outcome you get $100, i.e. $37 profit at a risk of $63. Profit and risk are visible before the trade, and the price can't “change after your trade”: you already bought the share at a specific price.

A Yes or No share is an on-chain token under the conditional-tokens standard. It actually sits at your address; you can sell it any time before settlement or wait for redemption. That’s exactly why a position can’t be “cancelled” by us — it’s yours, like any other token in the wallet.

Yes, at any time. The share sells at the current market price: that’s how people lock in profit on good news or cut a loss without waiting for the outcome. The market runs around the clock, with no days off.
