Building smart contracts on Bitcoin Layer 1. OP_NET has no protocol token. All fees paid in $BTC. Live on Mainnet 🟠

Bitcoin Layer 1
Joined August 2023
OP_NET smart contracts compile to WebAssembly. That means they can be written in over 20 languages, including Rust, Python, JavaScript, Go, C++ and AssemblyScript. There is no new VM to learn. The language you already use is the language you build with.

OP_NET is open source. Anyone can read the code, run a node, and verify that contracts execute exactly as the protocol specifies. The design minimizes trust assumptions beyond Bitcoin itself, which has remained continuously operational since 2009.

Every financial tool on every other chain requires you to leave Bitcoin to use it. OP_NET changes that. Swapping and staking run directly on L1, settled by Bitcoin's miners. Your keys never leave your hands. Self-custody and smart contracts were never mutually exclusive.

NEW: #BITCOIN IS BEATING CRYPTO BY GOING SLOW A new metaprotocol is turning BTC’s slow and boring design into a superpower. With @bc1plainview, we discuss: 📌 Why BTC is hard to change 📌 Why fast “crypto” projects keep blowing up 📌 How BTC apps should be built Watch ⚡️

🎙️ Ep. 724 OP_NET | Building Native Functionality on BTC (feat. Samuel Patt) — — — For episode 724 of the BlockHash Podcast, host Brandon Zemp is joined by Samuel (Chad) Patt, Co-founder of @opnetbtc. OP_NET enables smart contracts directly on Bitcoin Layer 1, with no bridges, sidechains or Layer 2s. BTC is used as gas, keeping all security and liquidity native to Bitcoin. This unlocks stablecoins, lending, trading, staking and DeFi entirely on Bitcoin without wrapped assets or custodial risk. Samuel has always pursued opportunities that challenge conventional market cycles and push the boundaries of narrative. Coming from a punk background, his passion for Bitcoin stems from its decentralized architecture and anti-establishment ethos. In 2023, alongside his co-founders Danny and Anakun, Samuel began building toward a more productive Bitcoin - one capable of hosting smart contracts, institutional-grade infrastructure, and open financial applications. That journey culminated in the creation of OP_NET, a protocol representing his core philosophy: continuously redefining what’s possible on Bitcoin in a decentralized and permissionless way. 🔗 Spotify: tinyurl.com/3nr8392b 🔗 Apple Podcasts: tinyurl.com/y9rasxvc 🔗 Amazon Music: tinyurl.com/4u2xxp2w 🔗 YouTube: tinyurl.com/38us8ehs ⏳ Timestamps: (5:07) Is Bitcoin DeFi viable?

OP_NET doesn't add anything to Bitcoin. It reads from and writes to the same chain, using the same consensus, settled by the same miners. The smart contracts are new. The trust model isn't.

If you can write TypeScript, you can build on Bitcoin L1. OP_NET smart contracts use AssemblyScript. Same syntax, same tooling. 148+ contracts deployed in 6 weeks by independent teams. The infrastructure is open.

Smart contracts have been running on Bitcoin L1 for 5+ weeks. The protocol is stable, developer tooling is improving, and teams are deploying independently. We built the rails. Bitcoin DeFi is what builders do with them.

Bitcoin doesn't need to be fast. It needs to be trusted. That trust now extends to smart contracts, DeFi, and programmable finance. all on L1. The foundation was always there. The infrastructure finally caught up.

Most "Bitcoin L2s" aren't scaling Bitcoin. They're extracting from it. Our take on what separates real Bitcoin scaling from sidechains with Bitcoin branding and why we built OP_NET the way we did. Published on @hackernoon. hackernoon.com/bitcoin-layer…

Smart contracts directly on Bitcoin Layer 1. No bridges. No sidechains. No separate tokens. Chad Master @chadmasterxbt, Co-Founder of @opnetbtc, takes the Proof of Talk stage this June. OPNet launched mainnet in March 2026 as the first smart contract protocol built directly on Bitcoin L1. Chad came to Bitcoin through an unlikely path. Punk scene first, then years as a professional trader. Both taught him the same thing: question everything the mainstream accepts as given. In Bitcoin, the accepted given was that you need a second layer or a different chain to run smart contracts. Chad built the proof that you don't. He is also CBO of Orange Pill Labs, the Abu Dhabi-licensed company he co-founded. Orange Pill Labs works directly with exchanges, custodians, and institutional players to bring programmable Bitcoin infrastructure to the financial system. Make Bitcoin programmable without breaking what makes it Bitcoin. That's what OPNet does. June 2–3 at the Louvre Palace, Chad is on stage to show how. Passes are moving. tickets.proofoftalk.io/passe…

The SlowFi thesis is exactly the kind of research this space needs. Bitcoin's friction isn't a limitation, it's a structural advantage for DeFi that faster chains can't replicate. Appreciate @dl_research putting the data behind what we've been building toward.
For the first time, fully expressive smart contracts run directly on Bitcoin L1. No bridging, no wrapped tokens, no voodoo. @opnetbtc introduces a complete DeFi stack for the most liquid asset in crypto, powered by the SlowFi thesis: dlnews.com/research/internal…
