Halliday, an AI-powered startup specializing in workflow automation, has raised $20 million in a Series A funding round led by Andreessen Horowitz (a16z). The capital will accelerate the growth of its Workflow Protocol, which streamlines the development of financial applications by eliminating the need for traditional smart contracts.
Halliday’s innovative protocol provides developers with a faster, safer, and more cost-effective solution for building financial applications. By integrating AI and blockchain technology, the Workflow Protocol removes the complexities associated with writing smart contracts.
Highlighting the challenges of traditional development, Halliday noted: “Smart contracts have long been the default way the industry builds applications on-chain. However, smart contract development resembles hardware engineering more than software engineering: it is slow, expensive, and dangerous.”
The Workflow Protocol simplifies tasks like on-ramping to new blockchains, managing recurring payments, and optimizing yield. Additionally, it supports treasury management and automates operations for business-to-business agents.
Halliday’s approach has attracted prominent financial institutions, charter banks, and payment providers. Its system has been in testing since 2023, with successful integrations by platforms like Avalanche, ApeCoin, DeFi Kingdoms, and Story Protocol. Notably, SKALE Network and ApeChain also adopted Halliday’s workflow automation in 2024.
The latest funding round also saw participation from SV Angel, Credibly Neutral, and the Blizzard Fund. This follows Halliday’s earlier $6 million seed round in August 2024, also led by a16z, which focused on supporting blockchain gaming and metaverse ecosystems.
By enhancing operational efficiency and reducing reliance on traditional coding, Halliday positions itself as a leader in AI-powered blockchain automation. With the new capital, the company is set to further refine its protocol and expand its partnerships.
