Zyfai
Zyfai is a decentralized finance (DeFi) platform that functions as an automated, cross-chain yield agent. It is designed to optimize yield generation for users by automatically rebalancing their funds across various DeFi protocols and blockchain networks. The platform operates on a non-custodial basis, providing each user with an individual smart wallet to ensure they maintain sole control over their assets. [1] [2]
Overview
Zyfai aims to simplify the process of yield farming in the DeFi space, which can often be complex and fragmented across multiple blockchains. The platform's core value proposition is to provide a unified interface for managing assets across different ecosystems, summarized by its "All Chains, One balance" concept. It addresses the challenge of manually tracking and moving funds to find the best returns by employing automated "agents." [1]
Users can define their own investment strategies by selecting from a list of pre-approved protocols and setting specific parameters. The Zyfai agent then autonomously executes these strategies, rebalancing assets to capitalize on the highest available yields without requiring constant user intervention. This model is intended to improve capital efficiency and provide a passive earning experience for its users. The platform's infrastructure is built on smart contract wallets, which prevents the commingling of user funds in shared vaults and reinforces the principle of self-custody. [1] [2]
Technology and Architecture
Zyfai's architecture is centered around three key components: automated agents, non-custodial smart wallets, and a cross-chain framework. These elements work together to provide an automated and secure yield optimization service. [1]
Automated Yield Optimization
The central feature of the platform is its use of customizable agents that act on behalf of the user. These agents continuously monitor the DeFi landscape for optimal yield opportunities within the user's predefined strategic boundaries. Once a more profitable opportunity is identified, the agent automatically moves the funds to capture the higher yield. This process is designed to be fully autonomous, allowing for continuous optimization. [1]
Non-Custodial Smart Wallets
Upon depositing assets into the platform, each user is issued a personal smart wallet. This approach is fundamental to Zyfai's non-custodial security model. Unlike platforms that pool user funds into a single large vault, Zyfai ensures that assets remain segregated and under the exclusive control of the individual user. This means users retain ownership and can withdraw their funds at any time without needing permission from the platform. [1]
The use of individual wallets also provides a higher degree of security and transparency. The agent's actions are confined to the user's own wallet and are governed by permissions set by the user, mitigating risks associated with shared vault exploits. [1]
Technical Implementation
Zyfai's technical stack leverages established and emerging standards in the Ethereum ecosystem to build its smart wallet infrastructure.
Smart Wallet Infrastructure
The platform's smart wallets are built using Safe (formerly Gnosis Safe), a widely recognized standard for secure, multi-signature smart contract wallets. To enhance modularity and future compatibility, Zyfai implements Safe7579, which ensures its wallets are fully compliant with the proposed ERC-7579 standard. ERC-7579 aims to standardize the interface for modular smart accounts, allowing for features and functionalities to be added or removed like plugins. [1] [2]
Session Keys
To grant the automated agent the necessary permissions to manage funds, Zyfai utilizes a mechanism known as session keys. This is implemented using Rhinestone SmartSession. Session keys provide the agent with temporary, restricted permissions to interact with specific DeFi protocols on the user's behalf. This method offers granular control, as the user can define the scope and duration of the agent's permissions, enhancing security by limiting the agent's capabilities to only what is necessary for rebalancing. [1]
Ecosystem and Integrations
As of November 2025, Zyfai operates across several blockchain networks and has integrated a variety of major DeFi protocols to source yield opportunities.
Supported Blockchains
The platform's cross-chain functionality is supported on the following networks:
This multi-chain support allows the platform to aggregate yield opportunities from different ecosystems, providing users with a broader range of investment options. [1]
Integrated DeFi Protocols
Zyfai's agents can rebalance funds across more than ten different DeFi protocols. The integrated protocols include:
The platform is live across over 34 liquidity pools within these protocols. [1]
Market Adoption and Metrics
As of November 11, 2025, Zyfai reported several key metrics reflecting its growth and activity. The platform states that its data is sourced from on-chain analytics platforms such as Dune and DeFiLlama.
- Total Value Locked (TVL): $8.5 million
- Users: 9,022 deployed smart agent wallets
- Total Rebalanced Volume: $928.7 million
- Capital Efficiency: The platform claims a +122% improvement in capital efficiency for its users.
These figures indicate the scale of assets managed and the volume of automated transactions performed by the platform's agents. [1]
