How It Works

Gameday’s trading process is intended to be intuitive for users familiar with traditional exchanges, while integrating the benefits of blockchain technology.

1. Connect Your Wallet​

Begin by connecting an Optimism-compatible wallet, such as MetaMask. This step establishes your identity and ensures that your assets remain under your control until you choose to trade or settle.

  • Click Connect Wallet button.

  • Once connected, you will be prompted to sign a SIWE message to verify your identity.

1.a. Approve Allowance​

Before trading, you should set USDC ERC20 allowance for the Gameday Exchange contract. This sets a maximum amount of funds that the contract can access for trading, providing an additional layer of security and control over your assets.

  • Click Allowance button.
Set Allowance
  • Enter allowance amount - this will set a limit on how much you can spend on the exchange from your account.

2. Select a Market​

Explore available sporting events through the web interface or programmatically via the REST API. Each market represents a binary contract with two possible outcomes (“Yes” or “No”), allowing you to take a position on the result of an event.

3. Place an Order​

Specify your desired price and quantity for a contract. Orders can be limit or market orders, and remain open until matched with a counterparty. The order book displays all active offers, supporting transparent price discovery.

4. Matching and Execution​

Orders are matched based on price-time priority within the central limit order book. Once a match occurs, the trade is executed via the Pool contract, swapping positions between participants in a trust-minimized manner.

5. Event Resolution​

After the sporting event concludes, the Pool contract receives the official outcome from the Gameday Oracle. Following resolution, all positions are settled on-chain. Users can claim any resulting payouts directly from the Pool contract, with all transactions recorded immutably on the blockchain.

6. Settlement Fees​

A small platform fee is applied to each settled trade or position. These fees are collected and 100% are distributed from the Staking Pool, supporting the ongoing operation and security of the ecosystem.
