Show HN: DomeAPI (YC F25) was acquired. pmxt is the open-source equivalent

Hi HN, I'm the maintainer of pmxt.
With Polymarket's recent acquisition of DomeAPI to bring their infrastructure in-house, there is a sudden gap for developers building cross-market arbitrage bots, tracking whale wallets, or running quantitative models across prediction markets. If you are trading across Polymarket, Kalshi, or Limitless, you need a unified API to avoid getting locked into a single exchange's ecosystem.
pmxt is stepping in to fill that void.
Summary
PMXT is an open-source development platform that provides a set of tools and frameworks for building decentralized applications. It aims to simplify the process of developing, deploying, and managing blockchain-based solutions across different industries.
