ERC-1155 tokens represent positions in prediction markets on-chain. Each unique combination of market and outcome side (e.g., “yes” or “no”) is tokenized as a distinct ERC-1155 token, enabling on-chain ownership and transferability of prediction market positions.

​
Token ID Generation

Each token ID is deterministically computed using a hash of:
  • Market ID - The prediction market identifier (e.g., "BTC-100K-2024-12")
  • Side - The outcome side (e.g., "yes", "no", "Lakers", "Celtics")
  • Exchange - The exchange name
This ensures that the same market and side combination always produces the same token ID across the system.

​
Token Metadata

Each token includes metadata such as:
  • Market title and description from the prediction market
  • Outcome side information
  • Token name and image
  • Market rules and details

​
Token Lifecycle

Buy Orders:
  1. Order is placed on the prediction market
  2. When filled, ERC-1155 tokens are minted to your smart wallet
  3. Tokens represent your position in that market
Sell Orders:
  1. You hold ERC-1155 tokens in your smart wallet
  2. Order is placed on the prediction market
  3. When filled, tokens are burned from your wallet
