// how it works
One deposit. Every market.
HoodPredict abstracts away the chain hopping. You hold ETH on Robinhood Chain — the protocol handles the rest.
01
Deposit ETH
Send ETH from any wallet to your HoodPredict address on Robinhood Chain. Detected in seconds.
02
Relay bridges
Under the hood, Relay routes your ETH cross-chain into USDC on Polygon — the settlement asset for prediction markets.
03
Position opens
Your stake is placed as a limit order on Polymarket liquidity. You see one clean position in your portfolio.
04
Close & receive
Exit any time. Relay routes the proceeds back to ETH on Robinhood Chain and credits your wallet automatically.
// settlement flow
One deposit. Six atomic hops.
You quote in ETH on Robinhood Chain. Under the hood we sweep, bridge via Relay, swap ETH→USDC on Polygon, sign an EIP-712 order to Polymarket's CTF Exchange, and reverse the whole route on exit — every leg verifiable on-chain.

Questions?
What am I actually trading?+
Real prediction-market positions sourced from Polymarket. You quote in ETH, Relay bridges to USDC-Polygon, and your position sits on Polymarket's order book — surfaced as a single line in your HoodPredict portfolio.
Where does my ETH go after I deposit?+
It lands in your dedicated HoodChain wallet, then gets routed by Relay across-chain into settlement collateral. You never leave HoodPredict — the entire flow is abstracted.

You get a HoodChain wallet that you fund at will. Positions are collateralized on-chain. When you close a trade, the proceeds are routed back to your wallet automatically.
