How Supranomics works

Supranomics is a prediction market built on Ethereum. Each market is a real-world question with a clear, verifiable resolution — for example, "Will ETH close above $5,000 by end of Q3 2026?". Traders buy YES or NO shares; each share pays out 1 ETH if it's right, 0 if it's wrong. The current price (e.g. 62¢) is the market's collective probability estimate.

Three core flows

  1. Connect any Ethereum wallet (MetaMask, WalletConnect, Coinbase, Rainbow). No KYC required for non-restricted jurisdictions.
  2. Trade binary or multi-choice markets. Buy YES if you think the answer will be true; NO if false. Sell anytime before resolution.
  3. Settle automatically on resolution date. Winning shares redeem 1:1 to ETH on-chain via a UMA-style optimistic oracle.

You always custody your own funds — Supranomics never holds your ETH. Smart contracts handle escrow, settlement, and dispute resolution.

Trading basics

How prices work

Every market has YES and NO shares. Their prices always sum to ~$1.00 (in ETH terms). A YES at 62¢ means the market thinks there's a 62% chance the answer is YES.

Buying

  • Buy YES at 62¢ — you risk 62¢ to win 100¢. If you're right, you get 1 ETH per share. If wrong, you lose your stake.
  • Buy NO at 38¢ — same math, opposite direction.

Selling early

Markets are continuous. If your YES position rises from 62¢ → 80¢, you can sell anytime to lock in the gain, even before the market resolves.

Slippage

Large orders move price. Use the slippage estimator in the bet modal — anything >1% will warn you.

Parlay rules

A parlay combines 2–10 prediction legs into one bet. All legs must hit for the parlay to pay. Payouts multiply.

Math

Combined probability = p₁ × p₂ × … × pₙ. Combined odds = 1 / combined probability. Example: three 50¢ legs → 0.5³ = 0.125 = 12.5% chance, 8x payout.

Limits

  • Min legs: 2. Max legs: 10.
  • Min stake: 0.001 ETH. Max payout cap: 500 ETH per slip.
  • You cannot parlay two legs from the same market.

Cash-out

Once 1+ leg has settled in your favor, the parlay's "cash-out" value rises. Tap Cash out now in the slip to lock partial gains. Cash-out fee: 1.5% of remaining value.

AI Agents

Agents are autonomous bots running on Ethereum smart accounts. Each has a defined edge, risk budget, and on-chain audit trail. They trade only with the funds you allocate — never your full wallet.

Available agents

  • Quant Sniper — scans crypto markets, detects mispricings using on-chain order flow + social signals. Edge: ~4.2% per trade.
  • Macro Analyst — reads news + Fed minutes + central bank speeches. Trades macro markets only.
  • Parlay Builder — auto-builds positive-EV parlays from your watchlist.
  • Sports Edge — model-driven NBA/NFL/EPL bets with live Vegas-line comparison.

Risk controls

Every agent has: max-loss-per-day (default 5% of allocated), max-position-size (default 10%), and a kill switch you can hit anytime. Try the built-in Deploy Agent simulator to see exactly what an agent would do — no real funds spent.

Gas

Supranomics settles on Base (Ethereum L2). Typical trade gas: < $0.01. Mainnet bridging via official bridge.

How markets resolve

Every market has a published resolution source written into the smart contract before launch.

Optimistic oracle

  1. On end-date, anyone can propose the winning outcome by posting a bond (1 ETH).
  2. A 24h dispute window opens. Disputers post a counter-bond.
  3. If undisputed, the proposed outcome wins.
  4. If disputed, a UMA DVM vote decides — and the loser's bond is slashed.

Disputed markets

If a market becomes ambiguous (e.g., resolution source goes offline), a fallback resolver is named in the contract. In a tied or unresolvable case, the market resolves 50/50 and stakes are returned net of fees.

Security

  • Smart contracts audited by OpenZeppelin, Spearbit, and Trail of Bits.
  • Public bug bounty: up to $250,000 via Immunefi.
  • All contracts are immutable after launch — no admin upgrade keys.
  • Time-locked treasury (48h) for any protocol parameter change.
  • Open source: github.com/supranomicsxyz

FAQ

Is this real money?

Yes — when connected to mainnet. Use Demo Mode to try the app with 100 simulated ETH first.

What chains do you support?

Base mainnet (default). Ethereum mainnet for deposits/withdrawals. More L2s coming.

What if I lose my wallet?

Supranomics never holds your funds — your wallet IS your account. If you lose your seed phrase, your positions are unrecoverable. Use a hardware wallet.

How are markets created?

The team creates seed markets. Token holders can propose new markets via on-chain governance. Threshold: 1,000 $SUPRA staked.

Are agents safe?

Agents trade only with funds you explicitly allocate. They cannot withdraw, transfer, or move funds outside Supranomics. You can pull your allocation back at any moment.

Where is Supranomics not available?

The interface is geo-blocked in the United States, United Kingdom, and OFAC-sanctioned jurisdictions. The smart contracts themselves remain accessible to anyone with an Ethereum wallet.
