How Wallet V Uses the Zyfai SDK to Bring Earn Into an AI Trading Wallet
@WalletV_io launched Earn on September 3, bringing Zyfai-powered yield directly into its app. Users can now put capital to work while they wait for their next trade, without moving to a separate yield interface.
For a trading wallet, that is a useful addition: between trades, users can now stay in stablecoins without taking on the work of finding and managing DeFi yield themselves.
Wallet V integrated the Zyfai SDK to offer automated yield directly in the app, without building its own yield management infrastructure. The wallet provides the user experience, and our infrastructure supplies the yield engine and automated management underneath it.
You can download Wallet V on iOS or Android and try the app here.
What makes Wallet V a good fit for agentic Earn
Wallet V is a mobile, self-custodial wallet built around AI-assisted trading through connected platforms such as @HyperliquidX, @Aster_DEX, and @Polymarket. Its product brings together perps, prediction markets, tokenized stocks, and swap and cross-chain functionality. Users can access different onchain activities from one app instead of managing a separate interface for each one.
Earn extends that product beyond trading. A user can choose to allocate stablecoins to a yield strategy while waiting for a trading setup to appear.
Wallet V explained its choice of infrastructure directly:
"We decided to integrate with Zyfai because it combines yield optimization with continuous risk monitoring, while keeping users in control of their assets."
That is the reason this integration fits the product: Wallet V can add agentic yield to its existing AI-powered product lineup.
What users get beyond an Earn button
The immediate benefit is access to yield from the same familiar interface users already use. Wallet V Earn lets users put assets to work directly from the app, while Zyfai searches for risk-adjusted opportunities across DeFi.
Instead of assembling a wealth management team or building an agentic yield solution from scratch, Wallet V integrated the Zyfai SDK, cutting time to market from months to days. Zyfai monitors pool liquidity, utilization, collateral health, APY stability, changes in TVL, stablecoin depegs, protocol health, governance changes, and sentiment on socials. Before moving capital to a higher yielding pool, the Agent checks whether the expected additional yield will cover execution costs within the required payback period.
Users therefore don't have to keep finding a new pool and manually moving funds every time APY changes. Scoped session keys allow the Agent to rebalance between approved pools: it can carry out permitted strategy actions without asking the user to sign every rebalance. Zyfai's Security Proxy Gateway validates transaction calldata, and the session key cannot authorize withdrawals to external addresses or interactions with contracts outside the approved tarrget registry.
Why integrate an SDK instead of building the yield stack from scratch
If a wallet team chooses to build an automated Earn product from scratch, adding an Earn tab is only the first step. The team also needs to integrate DeFi protocols, define rules for selecting pools and allocating funds, build the tools for executing transactions, and set up ongoing risk monitoring and rebalancing. That requires engineers and DeFi specialists to develop and maintain the system as protocols and market conditions change.
We built the Zyfai SDK so product teams can reuse our existing infrastructure instead of building their own from scratch. It is a TypeScript library that gives applications programmatic access to the same yield engine used by Zyfai app. For a wallet that wants automated, self-custodial Earn, this is a simpler path than developing and maintaining each component independently. Zyfai automates execution within user-approved permissions, and users retain ownership of their Safe Smart Accounts.
That gives Wallet V more than savings on hiring an internal wealth management team. Active rebalancing delivers yield outperformance compared to static DeFi strategies, while the Agents monitor pool health around the clock and move capital to a safer approved pool when a depeg or falling liquidity puts the position at risk. Zyfai's Agents monitor onchain and offchain data 24/7, without sleep, and can act within scoped permissions without waiting for a human operator to review and execute every move.
The Zyfai SDK covers the main parts of the experience:
- Connect the user's existing wallet and associate it with a pre-deployed Safe Smart Account on the first deposit.
- Handle deposits and withdrawal requests through the wallet's own interface.
- Configure the yield strategy and approved protocol or pool preferences.
- Retrieve positions, balances, earnings, APY history, and transaction activity for in-app reporting.
- Retrieve the wallets and AUAM associated with the partner's SDK key for product monitoring.
A wallet team can concentrate on onboarding, design, and the way Earn fits its existing product. Zyfai maintains the necessary infrastructure and operates the yield layer.
This is the practical meaning of an easier Earn launch: integrate the user journey instead of building a DeFi execution and risk operation from scratch.
What Wallet V gets: a broader product and a revenue path
Earn gives Wallet V another reason for users to keep using the app when they are not actively trading. They can manage a yield allocation in the same product where they access markets.
Users no longer need to move assets to a separate app to earn yield between trades. They can keep managing that capital through Wallet V, giving them a reason to stay in the wallet instead of taking their assets elsewhere.
Earn also gives Wallet V an additional revenue stream: the wallet can receive a share of the performance fees generated by capital deposited through its partner SDK key. Wallet V earns trading fees when users trade. It can now also earn a share of performance fees while users keep assets in Earn between trades. With an integration that takes days instead of months of in-house development, Wallet V can start generating recurring fee revenue as soon as those deposits begin earning yield.
A repeatable model for wallet builders
Other wallets can use the same SDK to build Earn around their own users. They keep control of the interface and customer experience, reuse our yield execution and risk monitoring infrastructure, and earn performance fees on generated yield.
With the SDK, a wallet team can offer Earn without building and maintaining its own DeFi execution and monitoring systems. It needs to make yield useful and understandable for its users, then connect that experience to infrastructure built to manage it.
