Blockchain payments innovator Halliday has secured $20 million in Series A funding, led by the renowned venture capital firm Andreessen Horowitz (a16z). The round also includes strategic participation from Avalanche Blizzard Fund, Credibly Neutral, Alt Layer, and a roster of high-profile angel investors—including Viktor Bunin (Coinbase), Jason Zhao (Story Protocol), Ekram Ahmed (Celestia), and Nikil Viswanathan and Joe Lau (Alchemy).
This latest investment brings Halliday’s total funding to over $26 million, following a $6 million seed round in 2022—also led by a16z—marking the firm’s continued confidence in Halliday’s vision for the future of onchain development.
Accelerating Onchain Innovation with the Workflow Protocol
At the heart of Halliday’s mission is the Workflow Protocol, a groundbreaking solution designed to simplify and accelerate blockchain application development. Unlike traditional models that rely heavily on smart contracts, Halliday’s approach eliminates the need for developers to write, audit, and deploy complex code.

The protocol enables automation of common financial and operational workflows—such as recurring payments, treasury management, L2 onramping, and B2B transactions—without requiring any smart contract development. This shift dramatically reduces time-to-market, allowing applications to launch in hours instead of months.
For businesses looking to integrate blockchain functionality, this means lower development costs, reduced security risks, and faster deployment cycles—all critical factors in today’s fast-moving digital economy.
Solving Real-World Challenges in Blockchain Development
Despite blockchain’s transformative potential, widespread adoption has been hindered by technical complexity. Smart contracts, while powerful, are notoriously difficult to build and maintain. They require rigorous testing, multiple security audits, and ongoing maintenance—similar to hardware engineering in their inflexibility.
Additionally, as artificial intelligence becomes more integrated into decentralized systems, new challenges around compliance, transparency, and control have emerged. Halliday addresses these issues by offering a structured, auditable framework where AI-driven processes can operate within defined parameters.
The Workflow Protocol provides enterprises with greater oversight and governance over automated processes, ensuring that even AI-powered actions remain compliant and traceable—a crucial requirement for regulated industries like finance and banking.
Bridging Web2 and Web3: A Gateway for Traditional Finance
One of Halliday’s most compelling value propositions is its ability to bridge the gap between traditional financial institutions and the decentralized web. Banks, fintechs, and payment processors can now access blockchain capabilities without needing deep expertise in smart contract programming.
With Halliday, these organizations can easily implement:
- Digital asset payments
- Stablecoin-based subscription models
- Yield-generating treasury solutions
- Programmable financial operations
This lowers the barrier to entry for mainstream adoption and opens new revenue streams for institutions eager to participate in the digital asset economy.
