For years, DeFi has dreamt of a borderless financial system:

What if you could access the best yields across every chain from a single position, without ever thinking about bridges, gas, or network selection?

This isn't a distant future. It's available on Tuesday via Zyfai's "One Balance. All Chains. Best Yields." The first truly autonomous yield optimisation upgrade that transforms how capital moves across chains.

The fundamental breakthrough of "One Balance. All Chains. Best Yields" is chain abstraction for yield generation. While others build bridges between chains, Zyfai is removing the concept of chains altogether from the user experience.

• One Balance: deposit once, access yield opportunities across chains.

• Agentic Strategy: choose networks/pools; your Agent handles rebalancing.

• Cross-Chain Atomic Rebalancing: funds are continuously optimized across all chains for best available yield.

• Gas/Bridge Fee Sponsorship: fees are abstracted away from end users and covered by Zyfai and Rhinestone.

• Tech stack: Warp by Rhinestone as a blazing-fast intent routing and execution engine with Across as battle-tested, trustless settlement layer for intent-bridge operations.

Your capital becomes a single, fluid entity that autonomously seeks the highest risk-adjusted returns across the entire multichain landscape. Meanwhile, the infrastructure required for this (bridging, gas payments, slippage protection) becomes invisible, abstracted away into an effortless, no-clicks experience.

At the core of "One Balance. All Chains. Best Yields" lies a sophisticated technical stack designed for security, efficiency, and absolute user control.

Self-Custodial Foundation

Unlike solutions that store keys in centralized providers or Trusted Execution Environments (TEEs), we never have access to your funds.

Every Smart Account is built on a Safe7579 multisig smart account that you fully control. You can always access your smart account via Safe UI and use it just like your EOA wallet: withdraw and deposit funds, swap, bridge, connect to other dApps, and so on.

It is your wallet and your keys.

Fee-Free Execution

Through Zyfai’s partnership with Rhinestone, we've eliminated the two biggest barriers to cross-chain DeFi: gas costs and slippage. Every cross-chain rebalance, every compound, every optimization is sponsored, meaning you capture 100% of the yield without erosion from transaction costs.

Intelligent Yield Discovery

Our system employs quantitative analysis across multiple dimensions:

• Our team of dedicated quantitative analysts (ex-Pictet) continuously model and validate opportunities

• Continuous monitoring of native yields across Base, Arbitrum, Plasma, Sonic, and expanding chains

• Data driven prediction of yield sustainability and risk factors

With over 33 pools integrated, Zyfai offers the largest number of yield opportunities on the market. Essentially, we identify and capture the best native yield opportunities before they become widely known.

Flexible Capital Management

Execute partial withdrawals from any chain while your Agent keeps the rest of your capital working for you.

Your funds stay liquid, self-custodial, and fully accessible whenever you need them, while Zyfai Agents continuously reallocate the remaining balance to the highest-yield opportunities across chains.

Flawless Auto-Compounding

Zyfai’s auto-compound mechanism has been stress-tested across market conditions without a single failure. Rewards are automatically harvested and redeployed, ensuring maximum capital efficiency without manual intervention.

Prefer not to auto-compound? Disable it and stack rewards, then withdraw them anytime.

Granular Strategy Control

Choose from preset strategies or customise every aspect of your yield generation:

• Protocol whitelists and risk parameters

• Chain preferences and allocation limits

• Rebalancing thresholds and frequency settings

What makes this possible is the implementation of Session Keys module by Rhinestone that provide temporary access to your smart account with specific permissions. The strength of Session Keys lies in their ability to limit actions based on predefined permissions.

Your Agent have precisely scoped permissions to execute rebalances on your behalf across protocols you’ve approved, but never have withdrawal authority over your funds.

"One Balance. All Chains. Best Yields" leverages Rhinestone‘s Warp protocol for intent-based cross-chain execution, with Across providing battle-tested settlement layer. The entire cross-chain rebalancing process completes in under 1.5 seconds with guaranteed, MEV-protected execution. No slippage, no gas cost.

Here’s how it works:

Step 1. Agent scans all supported protocols across all supported chains

The ZyFAI Smart Rebalancing v.2 Engine continuously monitors every supported protocol across all integrated chains:

• If the current position is still optimal, funds stay put.

• If a better yield is detected, the Agent initiates a rebalance.

Step 2. Intent is created, Warp executes cross-chain transaction

The Agent creates an intent, and Warp executes it using Across as the settlement layer:

• Warp finds the cheapest/fastest route and guarantees atomicity/determinism (no partial fills or race conditions).

• A relayer pre-funds the destination chain, delivering the exact output amount with slippage-free, MEV-protected execution.

• The Across settlement layer handles relayer repayment on origin chains; Warp coordinates this under the hood.

All fees are covered by Zyfai and Rhinestone.

Step 3. Funds are deployed

Once funds arrive, the Agent automatically allocates them to the selected protocol.

Total time for cross-chain rebalancing: under 1.5 seconds.

While most cross-chain solutions rely on message-based bridging with inherent security trade-offs, Zyfai leverages a fundamentally more secure approach through intent-based execution.

Traditional Bridges vs. Intents

Message-based bridges require real-time security of the messaging layer, creating constant attack vectors. In contrast, intent-based architecture separates the urgent user need (instant execution) from the complex security problem (cross-chain verification).

How It Works: Security Through Separation

• Instant Execution: Relay nodes pre-fund destination chains, delivering guaranteed outcomes in under 1.5 seconds

• Secure Verification: The actual cross-chain settlement happens afterwards using the most secure methods available (canonical bridges, ZK proofs, or optimistic verification)

• Atomic Guarantees: During cross-chain rebalancing, the engine claims assets on the origin chain first, with the destination chain fill executed immediately after, ensuring no partial fills and no race conditions.

Enhanced Protection

This architecture provides:

• MEV-protected, slippage-free execution

• Elimination of bridge hack risks during rebalancing

• Economic security through Across' battle-tested settlement layer

• Future-proof verification that improves as new security methods emerge

The result: cross-chain rebalancing with enterprise-grade security, zero user-paid fees, and guaranteed execution outcomes.

You can find more details about the technical implementation in our docs.

Zyfai is a fully automated solution that takes care of everything: from gathering information in real-time to taking onchain actions. The Zyfai Agent dynamically allocates your funds across chains and whitelisted protocols to optimise for the highest possible APY.

By default, the Zyfai Agent is set to auto-compound, allowing you to earn the best yield possible and enhance your capital efficiency.
