OP_NET Goes Live: Bitcoin Finally Gets Native Smart Contracts — No New Token Required
Bitcoin has always been the most secure, most liquid, and most trusted blockchain on Earth. What it has never been is programmable — at least not in the way Ethereum, Solana, or even newer L2s have trained developers to expect. That changes today. On March 17, 2026, OP_NET launched its mainnet, bringing fully expressive smart contracts to Bitcoin Layer 1 without introducing a new token, a sidechain, or a bridge. Every transaction fee is paid in BTC, and every contract executes on top of Bitcoin's own block space.
For a network safeguarding over $1.4 trillion in value, the arrival of native programmability is not a niche upgrade — it is the missing piece that could unlock a $200 billion-plus DeFi opportunity that has been sitting dormant inside the world's largest digital asset.
