What is Bullpen?
Bullpen is a non-custodial trading terminal for prediction markets and onchain trading. It brings Polymarket, Hyperliquid, and Jupiter Ultra into one product, then layers in smart money discovery, copy trading, and a CLI.
Core Principles
Self-Custody: Bullpen never takes custody of your funds. You trade directly from your own wallet using embedded wallets or linked external wallets.
Best Execution: Prediction markets execute on Polymarket's CLOB. Perps execute on Hyperliquid. Spot routes through Jupiter Ultra for Solana tokens and through Hyperliquid for listed spot assets.
Unified Experience: One interface for everything. No switching between apps to trade different markets or chains.
