Halliday raises $20 million to build AI agents that operate safely on blockchain
1 min read
Summary
AI start-up Halliday has raised $20m in a Series A funding round to develop blockchain-based AI agents that do not require the complex process of smart contract development.
Led by venture capital firm Andreessen Horowitz’s crypto division, the investment takes Halliday’s total funding to more than $26m.
The company has created the Agentic Workflow Protocol, which sets “immutable guardrails” for AI operations on blockchain networks, allowing autonomous actions within strictly defined parameters.
The approach solves a key challenge for AI developers, who want to safely deploy autonomous agents in decentralised environments, mitigating the risk of costly and irreversible mistakes.
Halliday’s workflow engine is already in use with high-profile partners including DeFi Kingdoms, Core Wallet by Ava Labs, and ApeChain.
The new funding will be used to expand the company’s team and development of its workflow protocol.
