About Halliday
Halliday is a blockchain payment platform that simplifies how users interact with crypto. Its core product, Halliday Payments, lets users log in with email or social accounts and buy tokens on any chain using fiat or existing assets, without needing to manage wallets, bridges, or exchanges. The underlying Workflow Protocol replaces traditional smart contracts with declarative workflows, enabling developers to automate complex operations like cross-chain swaps, recurring payments, and treasury management in hours instead of months.
The main pain point Halliday addresses is the fragmented and time-consuming onboarding process in crypto. Previously, acquiring a specific token could require navigating multiple platforms—payment gateways, bridges, and exchanges—each with different fees, interfaces, and geographic restrictions. This often took over 30 minutes and caused high user drop-off. Halliday reduces this to roughly one minute by intelligently routing payments through global networks and settling directly on the target chain.
In the past six months, Halliday has focused on expanding its network reach. Notably, it integrated TRON into its payment infrastructure in late October 2025, bringing its smart routing technology to TRON's large user base. This integration allows projects on TRON to offer unified payment experiences, letting users directly purchase TRON-based assets without multi-step conversions. The company continues to operate its Workflow Protocol in production for partners such as DeFi Kingdoms, Core Wallet, and ApeChain, while also preparing deployments with Story Protocol, Lens, and Frax. No major negative events were reported during this period.
Halliday's journey began in November 2021, founded by Akshay Malhotra and Griffin Dunaif. In 2022, the company raised a $6M seed round led by a16z crypto, launching a 'play now, pay later' solution for blockchain game NFTs, with a beta on League of Kingdoms. This marked its initial positioning as a payments gateway for gaming assets.
A pivotal shift occurred in 2023 when Halliday pivoted from a consumer-facing payments product to building the Workflow Protocol, a smart-contract-free automation engine. This transition, validated by production use with partners like ApeChain and Core Wallet, redefined the company as infrastructure for blockchain developers.
In March 2024, Halliday raised a $20M Series A led by a16z crypto, bringing total funding to $26M. This round accelerated the Workflow Protocol's development and Halliday Payments' expansion to over 35 clients, cementing its strategic shift toward developer infrastructure and AI-agent-ready workflows.
Important progress in the past six months:
- Completed a $20M Series A funding round led by a16z crypto, bringing total funding to over $26M.
- Launched the Claude Code plugin, enabling developers to build payment flows via natural language.
- Released the Agentic Workflow Protocol, allowing automated workflows without smart contracts, supporting cross-chain and multi-chain operations.
- Expanded network support to TRON, and announced partnerships with ApeChain, Avalanche Core Wallet, etc., with upcoming launches on Frax, Lens, Story Protocol, etc.
Future development focus:
- Continue improving the Agentic Workflow Protocol, achieving forward compatibility, automatically integrating new protocols and chains, reducing integration work.
- Emphasize zero-trust and immutable guardrails to ensure safe execution of AI agents, promoting AI-blockchain integration.
- Expand partner ecosystem to cover more L1/L2/L3, providing end-to-end payment solutions.
