1. Introduction
Halliday is a revolutionary project in the blockchain technology landscape, focusing on automating and simplifying the development of decentralized applications. It introduces the first-of-its-kind Agentic Workflow Protocol (AWP), enabling secure delegation of tasks to autonomous systems—such as software agents, AI, or scripts operating within predefined parameters.
This solution transforms the approach to creating Web3 applications. Instead of spending months or years developing and debugging smart contracts, Halliday allows the implementation of complex business logic within hours. The protocol eliminates the need for manual contract coding and reduces risks associated with code errors, vulnerabilities, and auditing complexities.
A distinctive feature of Halliday is the ability to set strict constraints and conditions under which autonomous agents can perform operations. This ensures processes are safe, transparent, and manageable, providing developers with a flexible tool for various tasks—from recurring transactions to cross-chain operations.
2. Halliday Workflow Protocol
Traditional smart contracts, despite their fundamental role in the blockchain ecosystem, often prove to be cumbersome, slow, and costly. Each new case requires writing a separate contract, undergoing expensive audits, and any changes or updates involve complex and risky code modifications. This hampers the introduction of new products, increases development costs, and demands significant resources for maintenance.
Halliday offers an alternative—the Agentic Workflow Protocol (AWP), which allows developers to describe business logic and conditions for operations through secure rules rather than smart contract code. This approach enables teams to focus on the product without delving into the technical complexities of blockchain.
Instead of traditional architecture, Halliday provides a modular, extensible platform on which powerful Web3 applications can be built with minimal overhead.
Advantages of AWP over traditional smart contracts:
- No need for code for each function: Developers set execution conditions through configurations, simplifying the process and reducing the likelihood of errors.
- High flexibility of logic: AWP supports dynamic workflows that can be adapted to specific needs without changing the underlying infrastructure.
- Reduced development and maintenance costs: Eliminating the need for complex audits and rewriting contracts lowers product development and support expenses.
- Rapid launch of new products: With templates and reusable modules, developing and deploying solutions takes significantly less time.
- Easy logic updates: Unlike smart contracts, which often do not support updates, Halliday allows modification of execution rules without restarting the entire application.
- Built-in security and control: The protocol ensures operations are performed within strict rules, preventing actions beyond set parameters and minimizing risks
- Native support for cross-chain operations: AWP is built with a multi-chain architecture in mind, enabling tasks to be executed across multiple networks without additional integration.
Thus, Halliday offers not just an alternative to traditional smart contracts but an entirely new paradigm for interacting with blockchain infrastructure. Its modular architecture and built-in support for autonomous agents open up broad prospects for automating financial, business, and user scenarios in the Web3 environment—without excessive complexity and technical barriers.
3. Halliday Payment System
Halliday Payments is the flagship application implementing the capabilities of the Agentic Workflow Protocol in practice.It is designed to simplify the transition from fiat currencies to cryptocurrencies and automates the entire token purchase process, including cross-chain operations. Users simply connect their wallet, such as MetaMask, and select the desired asset—the system handles the rest automatically, ensuring transparency, security, and control over funds.
Key features of Halliday Payments:
| Feature | Description |
|---|---|
| Token Purchase | Supports any tokens on supported networks, including cross-chain purchases. |
| Fiat Support | Allows purchasing cryptocurrencies using bank cards and payment gateways. |
| Wallet Integration | Compatible with MetaMask, WalletConnect, and other Web3 wallets. |
| Operation Automation | The system independently manages routing, bridges, and fees. |
| Security | Users do not transfer funds to third parties; control remains with them. |
| Multi-chain Support | Supports multiple blockchains: Ethereum, Avalanche, Arbitrum, and others. |
| User-friendly Interface | Provides a convenient user experience even for newcomers to Web3. |
Thus, Halliday Payments addresses one of the most pressing issues in the cryptocurrency ecosystem—the complexity of transitioning from traditional currencies to decentralized assets. Through automation, transparency, and security, the system makes Web3 more accessible and understandable for the mass user, while providing developers with a powerful tool for integrating payments into their products.
4. Project Use Cases
Halliday is a versatile protocol capable of transforming interactions with Web3 infrastructure. Its agentic workflow architecture allows for easy adaptation to various scenarios, from onboarding new users to automating complex decentralized operations. This approach lowers entry barriers and accelerates the adoption of blockchain solutions in business, fintech, and gaming products.
Key Use Cases for Halliday:
- Fiat On-Ramp to All Chains: Enables conversion of fiat to tokens on the desired network using a bank card or centralized exchange (CEX), eliminating intermediate steps and manual transfers.
- Cross-Chain Swaps: Halliday automatically identifies optimal exchange routes between blockchains and executes operations through bridges and decentralized exchanges (DEXs).
- Atomic Workflows: Combines multiple actions, such as purchasing, swapping, and staking, into a single secure transaction without manual intervention.
- Infrastructure for Fintech Products: Supports subscriptions, auto-payments, and other functions without the need to manually write smart contracts.
- Tools for DAOs: Automates voting, fund distribution, and decision execution within decentralized organizations.
- Applications in Games and Metaverses: Handles in-game transactions, rewards, and interaction logic between participants in the background.
Thus, Halliday becomes a key link between users, developers, and decentralized infrastructure. Its flexibility and compatibility with various blockchains allow for rapid development of products that previously required weeks or months of manual setup and costly audits.
5. Funding and Partnerships
In March 2025, Halliday successfully completed a Series A funding round, securing $20 million to scale its technology and expand its ecosystem. The round was led by venture capital giant a16z crypto, a significant endorsement for the industry. Other participants included Avalanche Blizzard Fund, Credibly Neutral, and Alt Layer—funds that actively support promising solutions in the Web3 and future infrastructure sectors.
The funds raised are allocated towards the development of the Agentic Workflow Protocol, strengthening the team, and launching new products, including tools for fintech, DAOs, and game developers. Partnerships with these funds provide access to an extensive network of experts, developers, and strategic initiatives, accelerating Halliday's integration into real-world use cases and major ecosystems.
These investments also highlight the growing interest in solutions that simplify blockchain interactions and eliminate technical barriers—precisely Halliday's focus.
6. Conclusion
Halliday represents an innovative solution for automating blockchain processes, enabling developers to create powerful applications more quickly and efficiently without the need to develop and audit complex smart contracts. By utilizing an agentic architecture and a well-designed workflow protocol, the project opens new horizons in Web3 automation.
Integration with artificial intelligence, support for cross-chain operations, and the high flexibility of the protocol make Halliday a universal tool for developers and businesses seeking scalable and secure decentralized solutions. This is not just infrastructure—it is the foundation for the next generation of Web3 products capable of adapting to rapidly changing market demands.
With a strong team, support from leading venture funds, and a strategic focus on user experience, Halliday is confidently moving towards becoming an integral part of the future blockchain ecosystem.
