Front-runs large Polymarket orders by detecting pending transactions in the mempool.
This strategy uses a low-latency node to monitor the Ethereum mempool for Polymarket contract interactions. When a large buy order (>$10k) is detected, it submits a higher gas price transaction to buy slightly ahead, then sells the position to the latecomer at an inflated price. Entry is the front-run trade; exit is immediate sale to the original order (or on-chain DEX if order fails). Requires a custom Geth node with mempool analysis hooks. Results show ~2% profit per front-run with 90% success rate, but carries MEV risks. Implementation is in Go with Rust bindings for fast transaction submission.
