Guardian.
Agentic AI that hunts cross-chain zero-day exploits, simulates full attack chains, and ships you fixes — before the next $292M disaster.

hundreds of millions.
In April 2026, Kelp DAO was hit through a LayerZero bridge exploit — forged messages minted $292M in unbacked rsETH, deposited into Aave creating $236M in bad debt, cascading into billions of TVL lost.
Traditional audit tools can't catch multi-step, cross-chain, zero-day combo attacks. Seeyuh changes this.
$292M
rsETH minted via forged messages
$236M
Bad debt injected into Aave
Billions
TVL wiped across DeFi

Zero-day report in minutes.
Upload your contracts
Paste Solidity source code or provide a contract address. Seeyuh fetches and prepares everything automatically.
Agent scans & simulates
Our agentic red team autonomously reasons through attack chains — cross-chain forgery, collateral inflation, oracle manipulation.
Get fixes in minutes
Receive a zero-day report with risk scores, PoC exploit paths, and actionable remediation — in under 5 minutes.
Everything your protocol needs.
Nothing you don't.
Zero-day contract scan
Upload Solidity files or bridge contracts. Find cross-chain forgery, collateral inflation, and vulnerabilities that traditional tools miss.
Kelp-style attack simulation
One-click replay: LayerZero forged message → fake token mint → Aave lending borrow. Customize parameters for your protocol.
Collateral integrity guard
Enter a lending pool address. Real-time verification of rsETH, stETH, and other asset backing — instant risk assessment.
Post-hack rapid forensics
Paste a transaction hash. The Agent traces the attack path, reconstructs the exploit, and generates a report with remediation steps.
5 minutes.
Protocol protected.
Walk through the real Kelp DAO attack and see how Seeyuh catches it before a single dollar is lost.
$ seeyuh scan KelpBridge.sol
[CRITICAL] Cross-chain message forgery vulnerability
→ LayerZero endpoint lacks origin validation
→ Unbacked rsETH can be minted via forged payload
[HIGH] No supply cap on cross-chain mint()
→ Attacker can mint unlimited tokens in single tx
[EXPLOIT PATH]
forge msg → mint fake rsETH → deposit Aave → borrow $292M
[FIX] Add DVN quorum verification + rate limiting on mint()
[FIX] Lending pool should verify collateral backing
Risk Score: 9.8 / 10 — 3 critical, 2 high findings
