Learn how SportToken delivers true fair odds, user‑first features, and a community‑driven betting experience. Inspired by prediction‑market mechanics, prices reflect the market’s view of probabilities rather than a house‑set spread.

Start BettingHow it works

What is SportToken

SportToken is a community‑first sports betting platform designed to give bettors the best possible experience: fair odds on both sides, the ability to cancel before games begin, user‑created props, and parlay payouts derived from real market probabilities—without a house edge. In traditional books, the “vig” compounds across legs. In our model, odds come from market liquidity, not a hidden spread.

In 2024, U.S. sportsbooks reported over $13.7B in profit. Our mission is to push value back to bettors by eliminating the structural edge and letting prices be set transparently by supply and demand.

  • No house edge on matchups
  • No platform fees (currently)
  • Cancel any pre‑game position for a full refund of stake
  • Create custom props and fair‑payout parlays

How Betting Works

Each matchup maintains two pools of USDC—one for each side. Odds reflect the ratio of liquidity between these pools and therefore the market’s probability. Because both sides are priced from the same pool state, bettors on both sides receive mathematically consistent odds.

Example

Thunder vs Celtics: suppose $600,000 is staked on Thunder and $300,000 on Celtics. The implied odds are −200 for Thunder and +200 for Celtics. If Celtics win, the entire Thunder pool moves to the Celtics pool and winnings are split proportionally. A bettor who staked $150,000 on Celtics owned 50% of the Celtics pool and would receive 50% of the Thunder pool: a $300,000 profit (+200).

Because odds are tied to pool sizes, your stake amount is constant while your potential win updates as prices move. You can cancel pre‑game for a full refund of your stake; there’s no penalty for odds movement prior to kickoff.

Key Implications

  • True fair odds. Both sides share a single probability surface. If one side is −150, the other is +150 (ignoring rounding) because there’s no house vig baked in.
  • Pre‑game refunds. Cancel any time before the game begins and receive your full stake back. Your position is fully liquid pre‑game.
  • No punitive cash outs. Unlike sportsbooks that hold your stake constant and vary your refund, we hold your stake constant and vary potential win—so exiting pre‑game returns 100% of stake.

Parlays

In legacy books, each leg includes a margin; combining legs multiplies margins into a large hidden edge. SportToken calculates parlay payouts from our fair odds per leg, yielding fair parlay payouts with no compounded house vig.

Parlay liquidity is funded by other users. To encourage liquidity, parlay funders receive a 3% share of the losing side’s profit when they fill the opposing stake. Parlays that include a custom prop are listed as a “Parlay Prop” in the Props section so the community can bid to take the other side.

Resolution: Parlays are currently resolved manually once per day at 12:00 AM EST (automation coming soon).

Props

Bettors can create their own player or game props in two ways:

  1. Fixed Props: Proposer sets both sides’ required stakes; another bettor can accept and the market locks until resolution.
  2. Bidding Props: Proposer escrows their stake and opens bidding; takers bid the counter stake, and the proposer can accept the best bid.

“Parlay Props” (parlays including a custom prop) are posted to Props so the community can bid to take the other side. Finished props are resolved daily at 12:00 AM EST.

How to Sign Up

Depositing

  • Card/Fiat via MoonPay: Purchase USDC and deposit directly. See MoonPay help (help center).
  • Transfer from Exchange: Buy USDC on an exchange (e.g., Coinbase) and send to your SportToken deposit address.
  • External Wallet Transfer: Send USDC from any wallet to your deposit address.
  • Receive Funds: Share your deposit address to receive USDC from others.

Withdrawals

  • Crypto Withdraw: Withdraw USDC to any crypto wallet you control.
  • Small Cash‑outs: For withdrawals under $2,000, consumer rails (e.g., Venmo, Apple Pay, Zelle) may be supported subject to availability, KYC, region, and risk checks.

Market Policies

  • Cash outs are disabled within 30 minutes of scheduled game time.
  • Betting is disabled during live play (live trading not yet available).
  • Matchups are resolved within ~15 minutes of game completion.
  • Props resolve daily at 12:00 AM EST; parlays resolve daily at 12:00 AM EST.
  • No pushes. We do not grade bets as pushes. If a football game ends in a tie, the payout is 50/50 between both sides based on each side’s share of the pools.
  • No both‑sides positions. To prevent wash trading and price manipulation, a single wallet cannot hold positions on both sides of the same market. This keeps prices honest and ensures that volume represents real conviction, not artificial churning. If you’d like to change sides pre‑game, cash out your position and re‑enter on the other side.
