Halliday Secures $20M to Revolutionize DeFi with AI-Driven Smart Contract Automation
March 18, 2025
Halliday, a platform focused on enabling developers to delegate workflows to autonomous systems for smart contract creation, has successfully raised $20 million in a Series A funding round.
This funding will be utilized to develop Halliday's Agentic Workflow Protocol (AWP), which aims to eliminate the need for traditional smart contracts in decentralized finance (DeFi) applications.
The new investment will help Halliday expand its capabilities, enhance its offerings in the blockchain space, and accelerate the adoption of blockchain technology.
By removing barriers for enterprise customers, Halliday allows businesses to leverage blockchain networks and AI agents without requiring specialized development teams, thus promoting faster AI adoption in financial services.
Halliday's middleware layer is designed to mitigate risks associated with rogue AI agents, making the integration of AI and blockchain more feasible for mainstream businesses.
The AWP facilitates secure interactions between autonomous agents and financial systems, thereby enhancing trustworthiness for enterprise applications.
Halliday's AI-enabled workflow engine has already been deployed with partners like DeFi Kingdoms and Core Wallet, automating complex processes such as treasury management and B2B transactions.
The company's mission is to enable developers to create applications in hours rather than years, promoting a shift from traditional smart contracts to no-code blockchain automation.
The funding round was led by a16z Crypto, a prominent venture capital firm known for its investments in cryptocurrency and blockchain technology, following a successful $6 million seed round in 2022.
With this latest funding, Halliday's total funding has surpassed $26 million, reflecting growing confidence in the company's innovative approach to AI deployment in decentralized environments.
This investment highlights the increasing interest in automating processes within the decentralized finance sector, as developers seek efficient solutions for smart contract deployment.
Halliday plans to enhance its AI workflow protocol and expand its team, having attracted talent from major tech companies like Alphabet, Meta, and Netflix.
