Artificial intelligence (AI)-focused blockchain protocol Halliday said it raised $20 million to help fund development of its Agentic Workflow Protocol (AWP), which aims to speed development of decentralized finance (DeFi) applications and avoid the need for programmers to write smart contracts.

The Series A funding round was led by venture capital giant Andreessen Horowitz's (a16z) crypto arm.

"Our mission is to pioneer the software era of blockchain, enabling developers to build applications in hours, not years," Halliday said in an emailed announcement. "With Halliday, you can never write a smart contract again."

Halliday’s no-code blockchain automation could help to accelerate blockchain adoption and shift development from smart contracts to AI-driven workflows, making blockchain more accessible, scalable, and efficient.

The funding round, which follows Halliday's seed $6 million round in 2022 — also led by a16z crypto — included contributions from Avalanche Blizzard Fund, Credibly Neutral and Alt Layer.
