Zyfai is an agentic yield layer that gives users, developers and curators self-custodial access to autonomous low-risk DeFi. Our customizable deterministic Agents transform idle capital into productive assets, rebalancing between curated opportunities to optimize capital efficiency and abstract onchain complexity from the end user. The result is sustainable and risk-adjusted yield, where your capital is always working and under your control.
Zyfai has been incubated by the Ethereum Foundation to push the boundaries of verifiability and security in low-risk DeFi.We have built a ZK-proof system based on the ERC-8004 implementation standard to verify these rebalancing rules onchain.

Why Zyfai?

As a liquidity provider, capital efficiency means earning higher returns with the same capital through smarter allocation. Protocols like Curve, Balancer, and more recently Fluid have made major progress by reducing idle liquidity and improving execution at the protocol level. But even if protocol-level inefficiencies are partially solved, a bigger problem remains. DeFi today spans thousands of protocols and positions across chains. Yields shift constantly as TVL, incentives, and market conditions change. Tracking and optimizing these opportunities manually is effectively impossible. That’s why we created Zyfai, an agentic yield layer for DeFi, specifically designed to:
  • Maximize capital efficiency through deterministic, rule-based automation
  • Abstract complexity from end users using audited, production-grade Account Abstraction tooling
  • Enable builders and curators to easily plug Zyfai’s agentic stack into their products via SDK
Unlike traditional shared vaults, where curators take control of user capital, Zyfai is designed for users who value personalization, transparency, and direct ownership. Under the hood, Zyfai leverages Safe7579 and Session Keys to provide a secure, customizable execution model where users retain full custody of funds and explicit control over protocol exposure. By default, Zyfai auto-compounds earnings and continuously reallocates capital to the highest risk-adjusted opportunity onchain, ensuring your capital never sits idle.

​
What is Zyfai today?

After more than a year of development, Zyfai has evolved from a single DeFi Agent into a full ecosystem of agents and tooling, or what we refer as the Zyfai agentic yield stack. The stack is composed of 4 core layers: zyfai-map-intro Together, these 4 layers make Zyfai not just a dApp, but a protocol:
  • For users: Access the Zyfai agentic yield layer across multiple front-ends, including zyf.ai, the Openclaw agent, Zoof Wallet, and other partners that have integrated the Zyfai SDK
  • For builders: Seamlessly embed an “Earn” product in your application (e.g. wallets, exchanges, neobanks, etc.)
  • For curators: Automate operations by integrating Zyfai’s execution layer into existing infrastructure
  • For protocols: Attract sticky TVL by offering incentives to Zyfai Agents
