Mammoth is a decentralised prediction market platform built on the Solana blockchain. Here's how you can create and participate in markets:

  1. Choose a Solana token: Enter the contract address of the Solana-based token you want to create a prediction market for.

  2. Set the target and deadline: Decide whether you're predicting the market cap or price. Choose either a "Long" (increase) or "Short" (decrease) position. Set your target value in USD or SOL, and select a deadline. The target must be at least 10% higher or lower than the current market cap or price.

  3. Create your market: Launch your market to allow others to bet for or against your prediction. The bonding curve mechanism ensures that early bettors are rewarded with better prices as more bets come in.

  4. Trading: Users can buy "Yes" or "No" tokens based on whether they agree or disagree with the market's prediction.

  5. Market Resolution: When the deadline is reached, the market is resolved using on-chain data to determine the outcome.

  6. Payouts: If your prediction is correct, you can claim your winnings. As the market creator, you also receive 1% of the final pot.

Mammoth implements a straightforward fee structure to maintain platform quality and support ongoing operations. Here's a breakdown of the fees you'll encounter:

  • Market Creation Fee: 0.1 SOL

  • Trading Fee: 0.1% of each transaction value

  • Winning Bet Fee: 0.1% of the withdrawn amount

The market creation fee helps prevent spam and ensures that only quality markets are created. When trading, a small percentage is applied to each transaction, contributing to platform maintenance and liquidity. Upon winning a bet, a final fee is deducted when you withdraw your earnings.

These fees serve multiple purposes:

  • Supporting day-to-day platform operations

  • Funding marketing initiatives to grow the Mammoth community

  • Buying back and burning $TUSK tokens, potentially increasing the value of remaining tokens

By implementing this fee structure, Mammoth aims to create a sustainable ecosystem that benefits all participants while supporting the long-term growth and value of the platform.

The outcome of a market depends on whether it's a "Long" or "Short" prediction. In a Long market, the token's market cap or price must reach or surpass the target value by the specified deadline for the prediction to be correct. Conversely, in a Short market, the token's market cap or price must remain below the target value until the deadline expires.

For cryptocurrency markets, the resolution process is automated, relying on data from trusted Solana-focused price oracles and aggregators. This ensures fair and accurate outcomes based on real-world data. World event markets, which are created by platform administrators, are resolved manually based on verified outcomes from reliable sources, maintaining the integrity of these special markets.

When a market resolves, holders of the correct prediction tokens (Yes or No) can redeem their tokens for SOL from the liquidity pool. To claim your winnings, ensure you have the correct SPL tokens in your connected wallet, then use the "Claim" function on the resolved market page.

As a market creator, you're entitled to a 1% share of the final SOL pot when the market resolves, regardless of the outcome. This incentivises the creation of engaging and well-thought-out markets. It's worth noting that tokens representing losing predictions become worthless upon market resolution. However, these tokens remain in your wallet as a record of your participation.

The Mammoth platform uses a bonding curve mechanism, which means that as more bets are placed, the price curve becomes steeper. This system rewards early bettors with better prices, but it's important to remember that early participants also have more capital at risk. This dynamic creates an engaging environment that encourages both early participation and ongoing market activity.
