Honest answers.
Real questions from real early users. If yours isn't here, email us — we'll add it.
Polymarket is a prediction-market exchange where users trade YES/NO outcome shares on real-world events (politics, sports, crypto, etc.). Markets resolve via the UMA optimistic oracle. We integrate with Polymarket International (polymarket.com), not the US Polymarket product.
Because the safest custody is no custody. Your wallet keys never leave your wallet. We build typed-data order payloads server-side, you sign in your wallet via WalletConnect, and we relay the signed order to the Polymarket CLOB. The platform holds zero keys and zero funds.
Same code, same live market data, same fee + slippage model — but no orders go to the chain. Every paper decision is logged just like a live one, with full P&L attribution. Promotion to LIVE is gated (re-auth, wallet balance check, explicit confirm).
To explore: no. You can sign up with email and run strategies in paper without ever touching a wallet. To trade live: yes — you'll need a Polygon-compatible wallet (MetaMask, Rabby, Coinbase Wallet, etc.) funded with pUSD.
Polymarket's V2 collateral token — an ERC-20 on Polygon mainnet, 1:1 backed by USDC. You bridge USDC into pUSD on the Polymarket deposit flow; that's the same pUSD our wrapper interacts with.
We mirror Polymarket's geo restrictions. If Polymarket blocks your region (US, UK, FR, and 30+ others), you get read-only access — you can browse, paper-trade, and research, but no live orders. In close-only regions (PL, SG, TH, TW) you can close existing positions but not open new ones. Compliance with your local laws is your responsibility. We do not detect or block VPN traffic, but bypassing restrictions via VPN is prohibited by our terms.
AWS eu-west-1 (Ireland). Public Polymarket ticker data is, well, public. User-specific data (account, wallet bindings, strategy state, decisions) is per-user, encrypted at rest, and never shared across accounts. We never share or sell user data.

Every market is scored 0.0–1.0 for resolution risk by a nightly process. Strategies refuse markets above 0.3 by default. You can see the score and the reasons inline, and override per-strategy if you accept the risk. Resolution risk is the single biggest hidden cost in prediction-market trading, and we treat it as a first-class signal.
Phase 4 (planned). You'll bring your own Kalshi RSA API key, encrypted per-user via AWS Secrets Manager. This is the only exception to "no API custody" — it's an opt-in, API-access custody only, never fund custody.
The Strategy SDK and primitives are intended to ship open-source (TBD on the exact license — likely MIT or Apache 2.0). Platform infrastructure (Next.js app, CDK, recorder) stays closed. The model is "open core" — write your strategies, run them on our platform or your own.
Subscription fees. Trading returns and risks belong entirely to the user. We're a tools business, not a fund.
