Security testing for smart contracts & Web3 protocols before launch
QAble combines adversarial security testing, fuzz simulation, and functional QA to protect your blockchain protocol before a single exploit costs you everything.
Trusted by teams that launch with confidence
Blockchain teams rely on QAble to surface critical vulnerabilities before mainnet and protect their users and reputation.
Why blockchain protocols fail after launch
On-chain bugs are irreversible. Unlike traditional software, a deployed smart contract vulnerability cannot be patched — only exploited.
Common outcomes without blockchain security testing:
One audit before launch is cheaper than one exploit after.
Blockchain security testing is protocol-survival — not a compliance checkbox.
QAble combines adversarial exploit simulation, structured audit methodology, and deep protocol expertise to protect your launch and your users.
Protocol Fund Exposure
Value at risk from unaudited smart contract logic before launch.
Bridge Attack Surface
Cross-chain bridges are the highest-value target in Web3 security.
DeFi Logic Exploit Rate
Proportion of DeFi hacks originating from unaudited protocol logic.
Post-Deployment Defect Cost
On-chain bugs cannot be patched — only exploited or abandoned.
Blockchain Testing Coverage Areas
Full-spectrum coverage from smart contract logic to cross-chain bridges, wallet integrations, and protocol performance under adversarial conditions.
Smart Contract Testing
Comprehensive validation of contract logic — reentrancy patterns, access control, integer overflows, upgrade safety, and gas optimisation across Solidity and Rust.
Security & Vulnerability Testing
Adversarial testing combining fuzz analysis, static code review, and exploit simulation to surface hidden attack vectors before your protocol reaches mainnet.
DeFi Protocol Testing
End-to-end testing of AMM logic, yield strategies, governance flows, and liquidation mechanisms under normal and adversarial market conditions.
Cross-Chain & Bridge Testing
Targeted auditing of bridge contracts, message relay logic, and cross-chain state consistency — the highest-risk surface in multi-chain deployments.
Wallet & Transaction Testing
Full-stack integration testing for wallets, dApp flows, signature approvals, and transaction handling across MetaMask, WalletConnect, and embedded wallet providers.
Performance & Scalability Testing
Stress testing under network congestion, high-volume scenarios, and Layer 2 rollup-specific conditions to validate your protocol holds under production load.
QAble Blockchain Testing Methodology
A structured security testing process from architecture review through exploit simulation to a launch-ready audit report.
Protocol & Architecture Review
Mapping your contract architecture, tokenomics, and on-chain/off-chain integration points to identify attack surfaces and define test scope.
Static Analysis & Code Review
Automated static analysis combined with manual code review to surface reentrancy patterns, access control gaps, and logical vulnerabilities early.
Functional & Integration Testing
Validating every contract function, cross-contract interaction, oracle dependency, and wallet integration against expected and adversarial inputs.
Security & Exploit Simulation
Fuzz testing, flash loan simulations, MEV scenario modelling, and bridge exploit testing validate your protocol under realistic attack conditions.
Audit Report & Remediation Support
Prioritised audit report with severity ratings, proof-of-concept exploit scripts, and hands-on remediation support to reach launch-ready state.
What you receive
Every engagement closes with structured audit evidence, remediation guidance, and a launch readiness assessment your team can act on immediately.

Common Blockchain Risks We Identify
These attack vectors and vulnerability patterns are the most frequent causes of protocol compromise, fund loss, and user harm in Web3.
Reentrancy & Fund Drain Exploits
Unguarded external calls allow attackers to recursively drain contract balances before state updates commit, resulting in total protocol fund loss.
Cross-Chain Bridge Compromises
Validation gaps in bridge contracts allow attackers to mint unbacked tokens or double-spend assets across chains, causing protocol-wide insolvency.
Governance Takeover Attacks
Flash-loan-funded governance exploits allow attackers to pass malicious proposals, redirect treasury funds, or disable security mechanisms in a single transaction.
Oracle Price Manipulation
Thin liquidity and single-source price feeds enable oracle manipulation attacks that trigger mass liquidations or allow unbounded borrowing at artificial prices.
Signature Replay Attacks
Missing nonce or chain-ID validation allows valid signatures to be replayed on other networks or reused to authorise unintended actions.
Gas Griefing & DoS Vulnerabilities
Unbounded loops and gas-sensitive external calls enable attackers to grief protocol operations, blocking legitimate users from interacting.
