Polkadot activates native smart contracts hub as DOT price hovers around $1.87

Polkadot's native smart contracts hub went live via a major runtime upgrade that also set a fixed 2.1 billion DOT supply and outlined lower long-term inflation. While the upgrade aims to speed up transactions and simplify development, DOT traded near $1.87 with muted price action, neutral RSI, modest inflows, and largely steady open interest.
