01 — Overview

What Oddsy is

Oddsy is two trading venues behind one wallet sign-in: prediction markets, and Hyperliquid perpetuals. You fund both from an Avalanche wallet, and money comes back to that same wallet.

Two halves, one sign-in #

The site has a prediction-markets half and a perpetuals half. They are separate venues with separate money, but they share the one thing that matters to you: the Avalanche wallet you signed in with. There is no second account to open, no email, and no password.

  • One signature signs you in. Your wallet address is the account key for everything that follows.
  • Separate money on each side. Each venue holds its own balance; funding one does not fund the other.
  • One way home. Withdrawals from either half go to the address in your session, and nowhere else.

Prediction markets #

Two kinds of yes/no question sit side by side, and both show up in the same portfolio.

Global questions

Mirrored from Polymarket

The big live questions — elections, rates, sport — mirrored from Polymarket. The provenance of a mirrored market is recorded rather than asserted in the interface: it carries the source condition id, so what settles it is unambiguous.

Avalanche-native markets

Settled from on-chain AVAX pools

Questions that live on Avalanche itself. Yes and No are pools held by the market's own contract; when the question resolves, settlement pays out of those pools. The price you see is the current implied probability, not a locked-in share price.

Hyperliquid perpetuals #

The perps half is a front end onto Hyperliquid's own order book. The market list is Hyperliquid's universe — around 178 markets — the book is its depth, the candles are its candles, and an order is signed and posted to its exchange. Nothing is simulated, and there is no house on the other side of your trade.

Margin is USDC, bridged from Avalanche by Relay. Because Relay quotes Avalanche to Hyperliquid directly, there is no separate Arbitrum bridge step to do first.
