In this week’s #AIMonday, we’ll introduce you to a platform developing AI-powered infrastructure to automate complex blockchain workflows across chains: Halliday.xyz.
Halliday.xyz is the online home of Halliday, a San Francisco, CA-based company developing an AI-powered blockchain protocol designed to automate complex digital workflows across multiple chains. The platform is geared toward streamlining blockchain-based commerce by handling multi-chain routing, gas payments, and transaction batching. In March 2025, Halliday announced a $20 million Series A funding round led by Andreessen Horowitz, with participation from Avalanche Blizzard Fund, Credibly Neutral, and Alt Layer.1
A key part of Halliday’s design is the Agentic Workflow Protocol, which uses AI to help developers connect financial operations—such as initiating payments or confirming transactions—into cohesive, automated workflows. These workflows can incorporate agentic AI, a form of AI intended to make decisions and take action with limited input. Halliday Payments, a first-party application built on the protocol, is designed to help users acquire tokens across chains, swap assets, and move between fiat and crypto while retaining control of their funds. It is also geared to handle routing, retries, gas payments, and other operations, with the goal of reducing manual steps in multi-chain transactions.
Halliday is led by CEO and co-founder Griffin Dunaif, and the team includes individuals with backgrounds from Stanford, Harvard, and Carnegie Mellon. Team members have previously worked at notable organizations such as Alphabet, Meta, Netflix, Stripe, and Compound. The company currently works with a range of stakeholders, including charter banks and payment service providers, to support early integration and feedback ahead of the full launch of the protocol.
Halliday’s choice of .xyz reflects its focus on open-ended innovation and wide applicability. The domain name Halliday.xyz is easy to remember and consistent with the naming patterns of projects operating across AI, blockchain, AR/VR, and emerging technology. As Halliday builds a system geared towards automation and scalability, .xyz aligns with its forward-facing, protocol-agnostic positioning. You can learn more by following the company on X/Twitter and LinkedIn, and by visiting Halliday.xyz.
