CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built for production by Web3-native engineers.
- Production-Ready Code: Built with
Solidity 0.8+,Vyper, orRust, followingOpenZeppelinstandards and security best practices. - Gas Optimization: Every contract is benchmarked and optimized to reduce user transaction fees by 15-40%.
- Full Audit Trail: Includes comprehensive unit/integration testing, documentation (
NatSpec), and preparation for third-party audits.
We deliver a battle-tested contract suite ready for mainnet deployment in as little as 4 weeks.

PROPERTY-BASED TESTING
How Our Automated Fuzzing Works
Our systematic, property-based fuzzing process uncovers edge-case vulnerabilities that traditional unit testing misses, delivering production-ready smart contracts.

DELIVERABLES
Outcomes: Secure Contracts, Faster Releases
Our fuzzing test automation service delivers concrete, measurable results that accelerate your development lifecycle and harden your protocol's security posture.
01
Comprehensive Vulnerability Detection
Automated fuzzing uncovers edge-case vulnerabilities—reentrancy, integer overflows, logic errors—that manual review and unit testing miss. We deliver a prioritized report with exploit PoCs.

A Quantitative Comparison
Manual Testing vs. Chainscore Automated Fuzzing
Traditional manual audits are slow and incomplete. Our automated fuzzing platform provides exhaustive, continuous security coverage for your smart contracts.
| Security Factor | Manual Audit Team | Chainscore Automated Fuzzing |
|---|---|---|
Test Case Coverage | Limited by time & budget | Exhaustive, property-based generation |
Vulnerability Detection Rate | ~70-80% (industry average) |
|
Time to First Report | 2-4 weeks | 24-48 hours |
Cost for Standard Audit | $15K - $50K+ (one-time) | From $5K/month (continuous) |
Regression Testing | Manual re-audit required | Automated on every commit |
Edge Case Discovery | Relies on auditor experience | Systematic exploration of state space |
False Positive Rate | Low (human-verified) | <5% with ML-powered triage |
Ongoing Monitoring | Not included | 24/7 with real-time alerts |

METHODOLOGY
Our Fuzzing Engagement Process
A structured, four-phase approach to deliver comprehensive smart contract security validation, from initial assessment to final report. We focus on uncovering edge-case vulnerabilities that traditional testing misses.
01
1. Discovery & Scoping
We analyze your codebase, architecture, and threat model to define a targeted fuzzing campaign. This includes identifying critical functions, state transitions, and custom invariants specific to your protocol's logic.
1-2 days

2. Campaign Configuration
Our engineers set up property-based fuzzing harnesses using tools like Echidna and Foundry. We define invariants (properties that must always hold) and differential fuzzers to compare against reference implementations.

3. Execution & Triage
Automated fuzzing runs generate millions of test cases. Our security team triages findings in real-time, classifying issues by severity (Critical, High, Medium) and providing reproducible proof-of-concept scripts.

Fuzzing Test Automation FAQs
Get clear, technical answers to the most common questions about our fuzzing-as-a-service for blockchain protocols.
A standard fuzzing audit for a typical DeFi protocol takes 2-3 weeks from kickoff to final report. This includes 1-2 weeks of active fuzzing with our proprietary engines, followed by analysis, report generation, and a remediation review call. Complex systems (e.g., cross-chain bridges, novel consensus mechanisms) may require 4+ weeks.
