Ark Labs, a developer of programmable financial infrastructure for the Bitcoin ecosystem, announced it has raised $5.2 million in a seed funding round backed by stablecoin issuer Tether and several venture investors. The funding will support the company’s effort to unlock Bitcoin capital and expand the capabilities of its core infrastructure platform, Arkade.
The round included participation from Tether, Ego Death Capital, Epoch VC, Lion26, Sats Ventures, and Contribution Capital. Additional investors included Anchorage Digital and Ralph Ho, former VP of Finance at PayPal. With the new capital, Ark Labs said its total institutional funding now exceeds $7.7 million following a previous pre-seed round backed by Draper Associates, Fulgur Ventures, and Axiom Capital.
Ark Labs is building infrastructure intended to enable programmable financial services on Bitcoin, an area historically limited by the network’s focus on basic value transfer rather than complex financial operations. The company’s platform, Arkade, serves as an execution layer that enables instant transactions and programmable financial operations for wallets, fintech platforms, and financial institutions.
According to the company, Arkade has been live since October 2025 and is already supporting development across multiple financial use cases, including payments, lending, and cross-network settlement. The platform aims to expand Bitcoin’s role beyond simple transfers to serve as a broader foundation for digital commerce and financial services.
Ark Labs said the platform introduces programmable capabilities that traditional payment networks rely on, including authorization processes, transaction holds, conditional payment terms, and escrow mechanisms. These functions are designed to enable more sophisticated financial applications and emerging use cases such as automated commerce, where AI agents execute transactions on behalf of users under predefined constraints.
Tether’s involvement reflects a broader push to expand stablecoin access on the Bitcoin network. The partnership is expected to accelerate the issuance, movement, and settlement of stablecoins directly on Bitcoin while improving liquidity and cross-border payment efficiency.
The newly raised capital will be used to expand Ark Labs’ team, strengthen developer relations, onboard new partners, and enhance the developer tooling required to scale stablecoin and Bitcoin liquidity together for production environments.
KEY QUOTES:
“Bitcoin is the most liquid digital asset in the world, but it has lacked the programmable infrastructure that financial applications require. Arkade changes that. Our partners are building payments, lending, and digital assets solutions on Bitcoin, and Tether’s involvement will be key to accelerate these efforts.”
Marco Argentieri, CEO Of Ark Labs
“Stablecoins were born on Bitcoin, and expanding access on the Bitcoin network remains a priority for us. Ark Labs is building infrastructure that makes it easier to issue, move, and settle stablecoins directly on Bitcoin. Improving access to USD₮ on the most secure and widely recognized blockchain supports greater financial inclusion, more efficient cross-border payments, and stronger global liquidity.”
Paolo Ardoino, CEO Of Tether
“Every fintech building digital products faces the same question: whose infrastructure do you depend on? On other networks, that infrastructure is increasingly permissioned, driven by a single company’s interests. Arkade is the open, neutral alternative.”
Alex Bergeron, Head Of Ecosystem At Ark Labs
