  Participated · Seed · Mar 2026

  Ark Labs is developing Arkade, an open, neutral execution layer that brings real-time, programmable operations—such as authorizations, holds, conditional terms, and escrow—to the Bitcoin network. Launched in October 2025, Arkade lets partners issue stablecoins, move digital assets, and settle payments natively on Bitcoin, supporting use cases in commerce, lending, and cross-network settlement. The platform is positioned to power autonomous commerce where AI agents transact under enforceable constraints. Ark Labs’ technology is aimed at fintechs, brokerages, asset managers, and payment companies seeking non-permissioned on-chain infrastructure. Headquartered in Lugano, Switzerland, the company has now secured more than $7.7 million in institutional backing. While revenue or user figures were not disclosed, the new capital will expand developer relations, product, and partner onboarding as Ark Labs scales stablecoin and Bitcoin liquidity at production levels. Its investor base includes prominent digital asset funds and industry operators, underscoring confidence in its vision for programmable finance on Bitcoin.
