We don't just review your protocol — we try to break it.
Intelligence Platform
Multi-Language Security: Solidity • Rust/Solana 🦀. We attack your protocol with 1,200+ exploit patterns derived from $40+ billion in DeFi exploits. Multi-layered toolchain + live execution + expert validation = find critical vulnerabilities in as fast as 24 hours, not 6 weeks. Our intelligence evolves with every audit.
Challenge Lifecycle
A systematic approach to validating your protocol's security through real-time attack execution.
1. Submission
Submit your smart contracts (Solidity or Rust), select language and blockchain (Ethereum, Solana, etc.).
2. Challenge Mapping
Challenges filtered by your subscription tier (6-26 challenges) and language selection.
3. Execution
Challenges run in isolated sandboxes with no external network access.
4. Validation
Vultbase security engineers verify findings and remove false positives.
5. Scoring
Findings are normalized and aggregated into a risk score.
6. Reporting
Receive a structured risk report with remediation guidance.
26 Challenge Categories • Tiered Access
From 6 core challenges (FREE) to 26 comprehensive exploit tests (ENTERPRISE), covering Solidity and Rust. Solana auditors are scarce—we're building deep Rust/Anchor expertise 🦀
Reentrancy
CriticalTests for recursive call vulnerabilities that could drain funds or corrupt state.
Access Control Bypass
HighValidates permission systems and role-based access control implementations.
Oracle Manipulation
CriticalSimulates price feed attacks and oracle data manipulation scenarios.
Signature Replay
HighTests for signature reuse vulnerabilities and replay attack vectors.
We Find What Top Auditors Don't
Our founder has personally discovered critical vulnerabilities in production DeFi protocols that passed previous third-party audits. These real-world findings — now systematized into 1,200+ exploit patterns — power every Vultbase scan.
Stale Oracle Price Vulnerability
CriticalContext: DeFi Lending Protocol
Identified incomplete oracle validation in Chainlink price feeds that passed a previous third-party audit. Missing answeredInRound check allowed stale price data during oracle failures.
Detection Method:
Security engineer review + Chainlink documentation cross-reference + exploit pattern matching
Unchecked ERC20 Return Values
HighContext: Token Integration Layer
Discovered 6 instances of missing return value checks on ERC20 transfer calls after initial audit cleared them. Non-standard tokens (USDT, BNB) could silently fail without SafeERC20 wrapper.
Detection Method:
Automated static analysis + manual validation against token standards
Vulnerabilities Hiding in Most Live Protocols
These aren't theoretical — they exist in production contracts right now. Our 1,200+ pattern database detects them before attackers do.
Infinite Token Approvals
Contracts requesting unlimited approve() on user tokens — a single compromised contract drains every wallet that ever interacted with it
Affects ~70% of DeFi protocols
How it's exploited:
Attacker exploits a separate vulnerability in the approved contract, then calls transferFrom() to drain every user's full token balance in one transaction.
Allowance pattern analysis + approve() scope audit + historical exploit matching
BadgerDAO ($120M) — attackers exploited injected approvals to drain user wallets
MEV & Frontrunning Exploits
Unprotected swap, liquidation, and arbitrage functions visible in the mempool before execution
Affects ~80% of DEX integrations
How it's exploited:
Bots monitor pending transactions, sandwich the victim's trade with buy-before and sell-after orders, extracting value from slippage. Also applies to liquidation and oracle update frontrunning.
Transaction ordering analysis + slippage parameter audit + mempool exposure mapping
$1.3B+ extracted via MEV in 2023 alone (Flashbots data)
Storage Collision in Upgradeable Proxies
Proxy and implementation contracts sharing overlapping storage slots — upgrades silently corrupt critical state variables
Affects ~40% of upgradeable contracts
How it's exploited:
During upgrade, new implementation writes to a storage slot that overlaps with proxy admin or balance data. Attacker triggers upgrade to overwrite owner/admin with their own address.
Storage layout diff analysis + EIP-1967 compliance check + upgrade simulation
Audius ($6M) — storage collision allowed attacker to overwrite governance
Why Standard Audits Miss These
Traditional auditors check code line-by-line. We cross-reference against 1,200+ real exploit patterns from $40B+ in historical hacks — Wormhole ($325M), Ronin Bridge ($625M), BadgerDAO ($120M), and 40+ more. Every Vultbase scan runs your contracts through attack scenarios that actually happened.

What Engineers Are Saying
“As protocols ship faster, relying only on one-time audits feels increasingly outdated. Continuous security and automated checks are the natural direction.”

Scoring & Risk Model
Our risk scoring combines severity, exploitability, and exposure factors to provide actionable security insights.
RISK SCORING
Findings are scored using industry-standard severity classification (CVSS-aligned), weighted by exploitability and real-world exposure data from our 1,200+ pattern database.
Verification Badge
Projects meeting security thresholds may receive a time-bound Vultbase Verified badge.
Critical
Immediate threat to funds or protocol integrity
High
Significant risk requiring prompt attention
Medium
Moderate risk with potential for exploitation
Low
Minor issues or best practice recommendations

Flag vulnerabilities before they ship
Vultbase plugs into your GitHub workflow. Every PR gets a security check. Critical findings block the merge — automatically, with zero friction.
Open a Pull Request
The GitHub Action triggers automatically on every PR that touches your contracts directory. No manual steps.
Analysis in Minutes
5 high-signal challenges run in parallel — reentrancy, access control, flash loan attacks, oracle manipulation, and arithmetic errors.
Block or Merge
If a critical vulnerability is found the PR check fails and blocks merge. Clean code ships. You choose the threshold.

Stay Verified with Quality Assurance as a Service
One audit isn't enough. Smart contracts evolve, and so should your security. Get continuous validation with automated re-testing on every update.
The Problem with One-Time Audits
Traditional audits become outdated the moment you push an update. A single line change can introduce critical vulnerabilities. Protocols lose their "verified" status and credibility after every deployment.
