Blockchain payments innovator Halliday has secured $20 million in Series A funding, led by renowned venture capital firm Andreessen Horowitz (a16z), marking a pivotal moment in the evolution of onchain application development. The round also includes strategic participation from Avalanche Blizzard Fund, Credibly Neutral, and Alt Layer, with additional backing from high-profile angel investors such as 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—highlighting the VC giant’s continued confidence in the company’s vision for simplifying blockchain integration.
The Workflow Protocol: Redefining Onchain Development
At the heart of Halliday’s innovation is its Workflow Protocol, a groundbreaking solution designed to enable onchain application development without writing smart contracts. Traditionally, building decentralized applications (dApps) has required complex, time-consuming smart contract coding, rigorous auditing, and months—or even years—of development.
Halliday flips this model by offering a streamlined infrastructure that automates common blockchain workflows such as:
- Onramping users to Layer 2 networks
- Managing recurring crypto payments
- Handling treasury operations
- Facilitating B2B blockchain transactions
👉 Discover how developers are cutting deployment time from months to hours.
By abstracting away the need for custom smart contracts, the Workflow Protocol significantly reduces development overhead, security risks, and time-to-market—making blockchain accessible not just to crypto-native teams, but also to traditional Web2 businesses and financial institutions.
Solving Real-World Challenges in Blockchain Adoption
Despite rapid advancements in blockchain technology, widespread adoption remains hindered by complexity. Smart contract development is often compared to hardware engineering—rigid, unforgiving, and expensive to iterate. A single bug can lead to catastrophic financial losses, making security audits and testing both essential and resource-intensive.
Moreover, as artificial intelligence begins to intersect with blockchain, new challenges emerge around compliance, transparency, and control. For AI-driven automation to function reliably onchain, businesses need infrastructure that allows them to monitor, audit, and govern automated processes in real time.
Halliday’s Workflow Protocol addresses these pain points by providing a secure, modular framework where workflows are pre-verified and composable. This ensures reliability while enabling rapid iteration—critical for enterprises exploring use cases like programmable money, automated settlements, or AI-integrated finance.
Strategic Partnerships and Real-World Validation
Since 2023, Halliday has been stress-testing its workflow engine with major players across the blockchain ecosystem. Notable collaborators include:
- DeFi Kingdoms – Leveraging Halliday for seamless in-game asset management
- Core Wallet (Ava Labs) – Integrating automated treasury functions
- ApeChain – Utilizing the protocol for cross-chain user onboarding
Upcoming integrations will expand to Story Protocol, Lens, Frax, and other leading Web3 projects—further validating Halliday’s role as a foundational layer for next-generation dApps.
These partnerships underscore a growing industry shift toward modular, interoperable infrastructure that empowers developers to focus on user experience rather than low-level blockchain mechanics.
Empowering Web2 and Traditional Finance
One of Halliday’s most compelling value propositions is its ability to bridge traditional finance with decentralized systems. Banks, fintechs, and payment processors can now tap into the benefits of blockchain—such as faster settlements, lower fees, and 24/7 transaction availability—without needing deep expertise in smart contract development.
Use cases enabled by Halliday include:
- Stablecoin subscription services (e.g., recurring payroll in USDC)
- Programmable treasury management (automated yield strategies)
- Digital asset payment rails (instant cross-border transactions)
- Regulated financial products with transparent onchain tracking

Frequently Asked Questions (FAQ)
Q: What makes Halliday different from traditional smart contract platforms?
A: Unlike conventional platforms that require developers to write, test, and audit smart contracts from scratch, Halliday’s Workflow Protocol offers pre-built, secure automation modules. This eliminates months of development work and reduces the risk of coding errors.
Q: Can non-crypto companies use Halliday?
A: Absolutely. Halliday is designed for both Web2 and Web3 businesses. Fintechs, banks, and SaaS platforms can integrate blockchain functionality—like recurring payments or digital asset handling—without hiring blockchain specialists.
Q: How does the Workflow Protocol handle security?
A: All workflows are built on a rigorously tested and audited base layer. Because no custom smart contracts are deployed per application, the attack surface is significantly reduced compared to traditional dApp development.
Q: Is Halliday tied to a specific blockchain?
A: No. The protocol is chain-agnostic and currently supports integrations across multiple networks, including Avalanche, Ethereum L2s, and emerging appchains.
Q: What role did a16z play beyond funding?
A: In addition to capital, a16z provides strategic guidance and ecosystem support. Their prior investment in 2022 signaled early confidence in Halliday’s vision, and this follow-on round reinforces their commitment to scalable Web3 infrastructure.

The Bigger Picture: Infrastructure for the Future of Finance
Halliday’s success reflects a maturing blockchain landscape—one where foundational infrastructure is becoming as critical as the applications built on top. Just as cloud computing enabled the rapid growth of mobile apps, simplified onchain tools like the Workflow Protocol are poised to accelerate Web3 adoption.
With strong backing from a16z and real-world validation from major blockchain projects, Halliday is positioning itself at the forefront of this transformation. As more businesses seek efficient, secure ways to engage with decentralized systems, platforms that remove technical barriers will play an increasingly vital role.
The $20 million raise isn’t just fuel for growth—it’s a signal that the era of frictionless blockchain integration is finally within reach.
