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.
- 2023 Seer Protocol Architecture Developed Seer Labs builds the modular architecture linking Gnosis Conditional Tokens with Reality.eth optimistic oracles.
- 2024 Gnosis Chain Launch & Yield Collateral Integration Deploys on Gnosis Chain and introduces yield-bearing collateral support to eliminate capital opportunity cost for long-term markets.
- 2024 Kleros Dispute Arbitration Layer Integrates Kleros decentralized court to serve as the ultimate dispute resolution layer for complex or contested market outcomes.
- 2025 Kleros Foresight & Futarchy Tooling Powers Kleros Foresight and launches dedicated futarchy modules allowing DAOs to guide governance decisions via market consensus.
- 2026 Cross-Chain DeFi Composability Framework Standardizes automated ERC20 wrapping and AMM liquidity pools for seamless outcome trading on external DEXs.
Seer utilizes Reality.eth for optimistic oracle submissions, backed by Kleros decentralized court as the ultimate dispute resolution arbiter.
Instead of locking collateral idle in a market contract, Seer routes collateral through interest-bearing DeFi protocols, allowing participants to earn yield while their predictions remain open.
Seer supports categorical (single/multi-select), scalar (numeric ranges), multi-scalar, and futarchy decision markets.
Outcome positions are created using Gnosis Conditional Tokens (ERC1155) and wrapped into standard ERC20 tokens for external trading and DeFi integration.
No, Seer is a fully permissionless, non-custodial smart contract protocol operating on open EVM blockchains.
