HyperNative Integration

Pre-transaction simulation, risk scoring, and compliance screening

Overview

HyperNative is an advanced pre-transaction security and simulation layer integrated into the Yield.xyz security stack.

It provides real-time transaction simulation, risk scoring, and compliance screening before execution — allowing both Yield.xyz and its partners to detect threats and policy violations before users ever sign a transaction.

HyperNative complements Shield, which validates a transaction’s structure and intent. Together, the two systems deliver complete pre-signing protection:

• Shield confirms that the transaction matches expected patterns
• HyperNative simulates the transaction to ensure it behaves safely and complies with policy

How It Works

Transaction Simulation

Every unsigned transaction built through the Yield API can be simulated via HyperNative.

The simulation engine runs the transaction in a sandboxed EVM environment, returning:

• Execution results
• Gas estimates
• Decoded call data
• State changes preview

Risk Assessment

Each transaction receives a risk score based on behavioral heuristics, audit data, and runtime behavior.

Common checks include:

• Contract impersonation detection
• Token transfer anomalies
• Approval limit mismatches
• Reentrancy patterns
• Flash loan indicators

Compliance Screening

Built-in Screener module performs real-time checks:

• OFAC sanctions: Flag sanctioned addresses
• Pool toxicity: Track tainted assets in DeFi pools block-by-block
• Counterparty risk: Evaluate transaction counterparties

Enables rules like:

• “Reject deposits into pools with >5% tainted assets”
• “Alert if counterparty is OFAC-linked”

Policy Enforcement

HyperNative supports custom policy creation using its dashboard or Python SDK.

Policies can:

• Block transactions
• Flag for review
• Trigger alerts
• Execute automated actions

Based on predefined conditions (gas anomalies, sanctions, tainted funds, etc.)

Integration with Shield

Layer	Function	What It Checks
Shield	Structure validation	Transaction matches expected pattern, addresses are correct
HyperNative	Behavior simulation	Transaction executes safely, complies with policy

Combined, they provide end-to-end transaction protection — structure + behavior.

---

Flow Summary

1. Build transaction

   Yield API builds unsigned transaction

2. Validate structure

   Shield validates structure and intent

3. Simulate behavior

   HyperNative simulates behavior and applies policy checks

4. Review results

   Client reviews simulation output and proceeds with signing

Policy Use Cases

Policy Type	Description	Example Rule
Security	Detect gas or approval anomalies	Reject transactions with >5× typical gas usage
Pool Toxicity	DeFi pool health monitoring	Reject deposits if >5% of assets are tainted
Sanctions	OFAC compliance	Block transactions involving sanctioned addresses
Monitoring	Continuous validation	Alert if pool risk level changes after deposit
Automation	Protective actions	Auto-pause affected yields during incidents

---

Automation & Guardian Layer

Policies can trigger automated actions when thresholds are exceeded:

• Pause affected yields
• Initiate withdrawals
• Send alerts to security teams
• Log for compliance review

Supports pre-signed transactions and limited execution roles (e.g., HyperNative acts as “pauser only”) for institutional setups.

---

API-Level Simulation

All Yield.xyz API-built transactions can be automatically simulated through HyperNative.

Direct API access

Partners can call HyperNative directly for independent validation before signing. This enables a zero-trust setup, ensuring transactions are verified even if built externally.

Client-side deployment

HyperNative can be deployed on the client side. Policies and compliance configurations used by Yield.xyz can be exported and imported into client-owned instances to confirm and simulate transactions prior to signing.

Custom policy control

Enterprise clients can define their own policies, risk thresholds, and automated actions — independent of Yield.xyz defaults.

---

Coverage

HyperNative protection covers:

• ✅ All EVM chains
• ✅ Major DeFi protocols
• ✅ Lending protocols
• ✅ Bridges and cross-chain
• ✅ Staking and restaking
