OddRouter
Cross-chain prediction market aggregator. Polymarket, and others
Project Description
OddRouter is a cross-chain prediction market aggregator. Route your bets to the best odds across Polymarket, and other platforms — in a single transaction. OddRouter scans live orderbooks across multiple prediction market venues, finds the best available price for any outcome, and routes capital cross-chain via LI.FI Composer. Users deposit on any chain and get matched against the deepest liquidity — regardless of where it lives. No manual bridging, no switching between platforms, no missed arbitrage. Built on LI.FI Composer SDK for atomic cross-chain execution, with a unified orderbook layer aggregating on-chain and off-chain prediction markets.
How it's Made
OddRouter is built around three core components.
Orderbook aggregation pulls live market data from Polymarket, and other venues, normalizing prices and fees into a unified orderbook. A routing engine identifies the best execution path, preferring same-platform fills and using cross-chain routing only when it improves pricing.
Cross-chain execution is powered by LI.FI Composer. Funds can be bridged and routed across chains before executing trades on the target prediction market.
Data layer is backed by ClickHouse for trade indexing and analytics, with a lightweight Next.js frontend showing aggregated markets and routing previews before execution.
LI.FI Composer was the key infrastructure layer enabling cross-chain capital routing across prediction market venues.
