Announcing Kontor

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 bridges. No wrapped assets. Just Bitcoin, powering a new generation of DeFi and application infrastructure.

ABOUT

UNLOCK BITCOIN'S FULL POTENTIAL

Kontor brings programmable assets and smart contracts directly to Bitcoin—no sidechains, no bridges, no wrapped tokens. Every transaction is a Bitcoin transaction, secured by Bitcoin's hashpower. Bitcoin becomes more than a store of value—it becomes the foundation for a thriving ecosystem of decentralized applications.

ACCESS DEFI WITHOUT LEAVING BITCOIN

With Kontor, there's no need to ever move your assets across chains. The protocol operates entirely on Bitcoin itself, 100% powered by the Bitcoin mining network, with the same security and finality. Execute smart contracts, swap tokens atomically, and participate in DeFi—all using your regular BTC wallet.

SMART CONTRACTS THAT ACTUALLY MAKE SENSE

Kontor's Sigil framework uses the WebAssembly Component Model to bring true type safety to Bitcoin smart contracts. Cross-contract calls are type-checked at compile time, re-entrancy is eliminated by design, and contracts compose like normal software. Build complex applications without sacrificing safety—errors are caught before they ever reach the blockchain.

SCALABLE FILE STORAGE, POWERED BY BITCOIN

Kontor enables scalable, perpetual file storage secured by Bitcoin. Files are highly replicated, and through challenge-response mechanisms and economic incentives, your data remain perpetually available—perfect for NFTs, application data, and blockchain-native storage needs.
