Seer

Seer is an open-source decentralized prediction platform designed to solve capital inefficiency and venue lock-in across Web3 forecasting markets. Built on Gnosis Chain and Ethereum L2s, Seer combines Gnosis Conditional Tokens Framework (CTF) with Reality.eth optimistic oracles to enable permissionless market creation across binary, categorical, scalar, and futarchy structures. To make outcome shares fully composable with external DeFi protocols like DEXs and lending platforms, Seer wraps ERC1155 outcome tokens into standard ERC20 tokens.

A key structural innovation of Seer is its support for yield-bearing collateral. Unlike traditional platforms where user funds sit idle while awaiting market resolution, Seer allows participants to stake collateral in yield protocols (such as Aave or Compound), earning interest throughout the market's lifespan. Continuous liquidity is maintained via Automated Market Makers (AMMs) rather than traditional order books, enabling friction-free trading even in long-tail or low-volume markets.

For dispute resolution and settlement integrity, Seer integrates directly with Kleros, a decentralized arbitration court. If an answer submitted through Reality.eth's optimistic bond escalation system is contested, randomly selected Kleros jurors review the evidence to render a final binding ruling. This modular architecture makes Seer a core primitive for decentralized decision-making, DAO futarchy governance, and long-term risk hedging.
