$POLY Polymarket just brought in ex‑Zora CEO Jacob Horne to fix its weakest link: the onchain product. CEO Shayne Coplan admitted that performance of Polymarket’s DeFi/onchain product has “waned” as the company scaled, and that some OG users feel the platform shifted focus toward its U.S. business. Horne is coming in with a broad product mandate to help unify Polymarket’s offerings and push a cleaner DeFi experience, while a major infra overhaul is already underway behind the scenes. The core fault line is Polymarket’s central limit order book (CLOB) on Polygon: VP of DeFi Engineering Josh Stevens recently called it “full of tech debt,” saying the current matching engine’s foundations are flawed enough that patching one issue can break another. The team is now rewriting the CLOB from scratch in Rust, targeting mid‑to‑late Q4, with early benchmarks showing 10–20x faster p99 latency and ~200,000 orders/second capacity — ~15x today’s throughput. Fees and liquidity incentives remain unchanged for now (category‑based taker fees, maker‑friendly rebates), but Coplan promised a DeFi town hall “soon” and invited users to send feedback directly to him and Horne as they shape the next version of Polymarket’s onchain product. #Polymarket #DeFi #Onchain #PredictionMarkets #Zora
