Kontor solves Bitcoin ecosystem fragmentation by wrapping arbitrary UTXOs into programmable receipt tokens via a FROST-secured Taproot vault, making any metaprotocol asset usable in Kontor smart contracts.

Bitcoin’s 10-minute blocks ensure unmatched security, but limit speed and scale. Kontor breaks this tradeoff with optimistic consensus and compact transaction encoding, enabling 1–2 second confirmations, 1,000+ TPS, and far lower fees—without leaving Bitcoin or changing its security model.

We're releasing the first alpha of the Kontor SDK — a TypeScript SDK for building applications on Bitcoin with the Kontor metaprotocol.

Bitcoin is the most trusted and secure blockchain in the world, but its design limits how far it can go. Kontor changes that — a Bitcoin metaprotocol built for creating, managing, and transferring value natively on-chain. No sidechains. No rollups. Just Bitcoin, powering a new generation of DeFi and application infrastructure.

Bitcoin is perfect money — but that’s exactly why it’s terrible fuel. Smart contracts need an asset that can move fast, flex with demand, and meter computation. Kontor’s dual-token model keeps Bitcoin as the store of value while introducing a purpose-built “digital gasoline” for execution, creating a system that’s both powerful and sustainable.

Sigil proves that Bitcoin smart contracts can be both powerful and readable. By combining WebAssembly with strong type safety, built-in checks, and human-friendly interfaces, developers get clarity without compromising on security.
