# Agent Vaults *The Invisible Layer That Handles Capital for All* By [Zyfai](https://blog.zyf.ai) · 2026-03-30 defi, vault, yield, agent, stablecoins, neobank, ethereum --- Of the $20B in onchain capital allocation, only $40M runs automatically. Most of DeFi's capital management is handled manually by wealth managers. Zyfai has proved that Agents can do more than optimize yield. They monitor risk constantly. The recent events with Resolv and Stream showed what happens when positions go unmonitored: depegs, liquidity traps, and users left exposed. Zyfai's Agents detected these risks and rebalanced user funds to safer opportunities faster than any human could. This happened across 13,000 wallets, moving $2B across 60 pools and 4 chains. Now imagine that same capability running directly from a vault, deployable and manageable by anyone through the Zyfai Dashboard. **The DeFi Gnomes can now handle wallets and vaults**. ![](https://paragraph.com/editor/callout/tip-icon.png) **DeFi Gnomes?** In Swiss folklore, gnomes were mystical creatures believed to operate beneath the surface, managing hidden resources and protecting value. This is what Zyfai's Agents represent: a hidden force that unlocks autonomous control over capital. Invisible because it abstracts all the complexity. **TL;DR: Agent Vaults, a new vault primitive from Zyfai powered by rule-based Agents. Live next week.** * **Deploy**: [Contract source](https://github.com/ondefy/erc7540-wrapper) (open, permissionless vault on GitHub) * **Explore**: [Zyfai Agent Vaults](http://zyf.ai/vault) (integrate automated yield in hours) * * * **From Wallets to Vaults** -------------------------- Zyfai started by building Agents for Smart Wallets. Each user gets their own Safe multisig with Session Keys that define strict guardrails for what the Agent can and can't do. That model works, and it powers everything described above. But as partners came to us (fintechs, neobanks, DeFi protocols), the need shifted. They didn't want to onboard users into individual Smart Wallets. They wanted something simpler: a single vault they could plug into, with all of Zyfai's automation running underneath. Deploy once. Manage from a dashboard. **Let the gnomes handle the rest**. That's why we built Agent Vaults. * * * **The Problem with Vaults Today** --------------------------------- ![](https://storage.googleapis.com/papyrus_images/8d9567a37681fc6ecde1fedbeafd29f49f784f889b3fea73eb811b039fe1879c.jpg) Most production vaults run on manual operations. The wealth manager is responsible for everything: updating the NAV from oracle data on every deposit, withdrawal, and rebalance. Adding new DeFi protocols by manually interacting with their frontends. Elaborating and adjusting strategies. Monitoring risk around the clock. Executing rebalances by hand. There is no standardized automation for any of this. The workload scales linearly with the number of strategies a vault runs, and it never stops. Earlier vault standards like ERC-4626 offered a clean synchronous interface: deposit, receive shares, withdraw. But synchronous operations can't support complex strategies that need to unwind positions across multiple protocols before settling. ERC-7540 solved that technical constraint by making operations asynchronous. In doing so, it created an operational one: every async vault now requires a human managing the settlement cycle. This presents a distribution problem. Fintechs, neobanks, and protocols want to offer DeFi yield to their users. But integrating vault-based yield today means either building an in-house wealth management team (specialized, expensive, available around the clock) or not offering yield at all. The infrastructure for complex yield strategies exists. The tooling to run them without constant human intervention does not. That's the automation gap, and it's why $19.96B of the $20B market still runs on manual operations. * * * **How Agent Vaults Work** ------------------------- ![](https://storage.googleapis.com/papyrus_images/c4fb41caff1a68af6e9d319a0c6575e367e54322106a57c3c44e45c83e321caf.png) We built a new vault contract, the Smart Account Wrapper, that automates the entire curation lifecycle. The concept is simple: the vault wraps a Safe Smart Account Agent. Every deposit into the vault redirects funds straight to the Smart Wallet, where Zyfai's automation takes over. An oracle and indexer sit in between to handle actions and accounting. From the integrator's side, it behaves like a standard ERC-4626 vault. Deposits go in. Yield accrues. Withdrawals come out. No async complexity exposed. Under the hood, it runs ERC-7540 for the complex operations that drive real yield. The wealth manager's manual work (NAV updates, withdrawal processing, strategy rebalancing, claim fulfillment) is replaced by Zyfai's automation infrastructure. The same Safe multisig and Session Key architecture that secures 13,000 individual wallets now powers the vault. * * * **Agent Vaults Flow** --------------------- ![](https://storage.googleapis.com/papyrus_images/3b79958fddb0a9d0891090ac988a4cb35159b1630d577d0b1b613e2d533f6bfd.png) Five components. Each has a single job. 1. **Safe Multisig (Owner)** has full control over the vault: upgrades, asset reallocation, parameter changes. No timelock on upgrades; the multisig threshold is the security boundary. This is a deliberate design choice, and users opt into the multisig's trust model. 2. **Vault (Smart Account Wrapper)** is the contract integrators and users interact with. ERC-4626 and ERC-7540 compliant. Manages share accounting, tracks the value of deployed assets, and supports ERC-1271 signature delegation for composability with aggregators, routers, and other ERC-7540 operators acting on behalf of depositors. 3. **Zyfai Smart Account** **(Agent)** is where allocated capital lives and DeFi strategies are executed. 4. **Oracle Service** syncs the NAV at each operation: deposits, withdrawals, and rebalances. When the Zyfai Smart Account executes transactions, the Oracle Service calculates the current value and reports it back to the Vault via capital out and capital back. 5. **Indexer** is the automation engine. Every 60 seconds, it polls pending withdrawals, and fulfills them through the Smart Account, sending requests to reallocate idle capital. 6. **Users and Partners:** Deposit, withdraw, and claim. ![](https://paragraph.com/editor/callout/information-icon.png) The vault contract is open and permissionless. Anyone can deploy an instance and connect it to a Zyfai Smart Account. Full architecture documentation, trust model, and contract reference are available on [GitHub](https://github.com/ondefy/erc7540-wrapper/blob/main/ARCHITECTURE.md). * * * **What This Unlocks** --------------------- When wealth management is automated, DeFi yield becomes pluggable infrastructure. * **For integrators.** A fintech or neobank can plug in a single ERC-4626 vault and offer yield strategies to their users without hiring a wealth management team, monitoring DeFi opportunities, or processing settlements. Their users get automated withdrawals with no claim delays. * **For wealth managers.** The operational burden that limits how many vaults they can manage disappears. A wealth manager focuses on strategy selection and risk parameters. Execution runs on its own. * **For Agents.** Agent-to-vault deposits open a new execution primitive. Autonomous agents will have the tools to allocate capital into vaults directly, enabling strategies like automated treasury management or cross-protocol yield routing without human coordination. 0.2% automation in a $20B market is early. As more capital flows onchain through consumer products that need embedded yield, the teams that can offer it without operational overhead will have a structural advantage. The automation gap is the opportunity. We're building the infrastructure to close it. **Welcome to Agent Vaults →** [**https://zyf.ai/vault**](https://zyf.ai/vault) * * * **About Zyfai** --------------- Zyfai gives you self-custodial access to autonomous low-risk DeFi.
