ArkLabs.xyz – GoDaddy customer – (Switzerland)
Developers in the Bitcoin ecosystem use .xyz domains to build infrastructure and expand decentralized finance. Hybrid blockchain project GoBob.xyz aims to bridge Bitcoin and Ethereum for decentralized finance. Bitcoin mining initiative Proto.xyz develops modular hardware and open-source management software. Web3 platform Omega.xyz aims to pioneer Bitcoin DeFi with cross-chain yield generation solutions. In this week’s #BlockchainThursday, we’ll introduce you to a project building programmable financial infrastructure on Bitcoin: ArkLabs.xyz.
ArkLabs.xyz is the online home of Ark Labs, a company building infrastructure for programmable finance on Bitcoin. According to its website, the platform is designed to support financial applications such as payments, escrow, and asset management using Bitcoin and stablecoins. Its core technology focuses on enabling offchain transaction execution while maintaining the ability to settle on Bitcoin. In March 2026, Ark Labs raised a $5.2M seed round led by Tether, a company that issues the USDT stablecoin. Additional participants included Ego Death Capital, Epoch VC, Lion26, Sats Ventures, and Ralph Ho, former VP of Finance at PayPal.1
Ark Labs positions its platform as infrastructure for financial applications rather than a standalone product. According to ArkLabs.xyz, the company highlights use cases across fintechs, brokerages, and asset managers, including settlement, liquidity strategies, and yield products. The platform is described as enabling continuous global transactions without intermediaries or fixed operating hours. The platform’s whitepaper describes a protocol that groups multiple transactions and settles them on Bitcoin, which can reduce onchain activity while allowing users to retain control of their funds. This approach situates Ark Labs within a broader set of efforts to expand Bitcoin’s role in financial systems by adding execution layers.
The company is led by CEO Marco Argentieri. According to his LinkedIn profile, he has worked across product and blockchain roles, including positions at Vulpem Ventures and SingularityNET, a decentralized AI network. At SingularityNET, he led blockchain strategy for the platform. He also held product leadership roles before becoming CEO of Ark Labs in 2024. Marco is also listed as Head of Innovation for Lugano’s Plan ₿ initiative, a Bitcoin-focused project in Lugano, Switzerland, as of March 2026.
ArkLabs.xyz selected a .xyz domain as the primary home for its Bitcoin-based financial infrastructure. This aligns with a broader pattern of blockchain and infrastructure projects adopting .xyz domains for developer-facing platforms and protocols. The domain presents the company’s focus on programmable finance and Bitcoin-based infrastructure, along with information about its technology and funding announcement. You can learn more by following the company on X/Twitter and LinkedIn, and by visiting ArkLabs.xyz.
