Fuzz Smarter.
Break Before They Do.

AI-powered smart contract fuzzing that detects DeFi exploits, reentrancy attacks, and economic vulnerabilities before they go on-chain.

How HyperFuzzing Works

Four steps from upload to full vulnerability report. No setup, no Foundry knowledge needed.

01

Upload Contract

Drop your Solidity or Vyper contract. HyperFuzzing AI parses the ABI, detects entry points, and maps all state-changing functions automatically.

Solidity · Vyper · Bytecode
02

AI Fuzzes It

Our AI generates thousands of adversarial inputs targeting DeFi-specific attack patterns: flash loans, reentrancy, oracle manipulation.

10,000+ mutations
03

Get Your Report

Receive a structured report with severity ratings, proof-of-concept exploit code, and recommended fixes ready for Immunefi or HackerOne.

Submit Bounty

Connect directly to bug bounty platforms. AI-formatted reports maximize acceptance rates. Track submissions and payout status in one place.

Everything You Need
to Hunt Bugs

Built for Web3 security researchers and protocol teams.

⚡

AI Mutation Engine

Action-based mutation generating semantically meaningful transaction sequences — not random byte noise. Finds more profitable exploits than classical fuzzers.

Core
🔁

Reentrancy Detector

Multi-level reentrancy analysis covering cross-function, cross-contract, and cross-chain scenarios. Detects read-only reentrancy and callback patterns.

AI-Powered
💰

Flash Loan Simulator

Simulates flash loan attack vectors across Aave, dYdX, and Uniswap V3. Tests price manipulation and governance attacks in forked mainnet.

Pro
📊

Oracle Manipulation

Detects reliance on manipulable price oracles and generates PoC transactions that demonstrate economic exploitability.

Pro
🧬

Invariant Testing

Define custom invariants or let AI generate them. Continuous fuzzing until invariant is broken with minimal reproducible test case.

Beta
📝

Bounty Report Generator

Auto-generates structured bug bounty reports with CVSS scoring, impact analysis, and formatted PoC. Optimized for Immunefi standards.

Popular
🔗

Mainnet Fork Testing

Run fuzzing against forked mainnet state using Alchemy or Infura. Test real protocol integrations with actual on-chain data.

Pro
🛡️

CI/CD Integration

GitHub Actions and Foundry plugin available. Auto-scan on every PR and block deployments if critical vulnerabilities are detected.

Beta
🌐

Multi-Chain Support

Native support for Ethereum, Arbitrum, Optimism, Base, Polygon, BSC, Avalanche, and more. Chain-specific attack patterns included.

Reentrancy in withdraw()

External call before state update. Est. $2.4M TVL at risk.

Oracle Price Manipulation

Uniswap V2 spot used for collateral. Single-block exploitable.

Missing Access Control

setFee() lacks onlyOwner modifier.
