FULL-STACK ENGINEERING
Custom Blockchain Development
End-to-end blockchain solutions from protocol design to production deployment.
- Protocol Design: Consensus mechanisms (
PoS,PoA), token economics, and governance models. - Core Development: Rust/Solidity/Go implementation with formal verification for critical modules.
- Node Infrastructure: Automated deployment, monitoring, and 99.9% uptime SLA for validator networks.
- Tooling & Integration: Wallets, explorers, and bridges to connect with
Ethereum,Solana, or other ecosystems.
We handle the entire stack so you can focus on your product, not the plumbing. From testnet launch to mainnet governance, we ensure your chain is secure, scalable, and ready for users.

THE CRITICAL EDGE
Why Specialized Stealth Testing is Non-Negotiable
Standard testing catches known vulnerabilities. Our stealth testing simulates sophisticated, real-world adversarial behavior to expose the hidden attack vectors that threaten your protocol's assets and reputation.
01
Simulate Sophisticated Adversaries
We deploy custom bots and attack scripts that mimic the tactics of elite exploit hunters, testing for MEV extraction, flash loan attacks, and governance manipulation before mainnet launch.

PROVEN FRAMEWORK
Our Methodology: The Chainscore Process
A systematic, four-phase approach to stealth contract testing that de-risks your launch and ensures protocol integrity. We deliver actionable security insights, not just automated reports.
01
1. Architecture & Threat Modeling
We begin by analyzing your contract's design and business logic to identify attack vectors before a single line of code is written. This proactive phase maps out potential exploits, from reentrancy to governance manipulation, establishing a comprehensive security baseline.

2. Targeted Fuzzing & Simulation
Our engineers deploy advanced fuzzing tools (Foundry, Echidna) with custom invariant tests to stress-test your contracts under millions of simulated states. We go beyond standard tests to uncover edge cases in complex financial logic and MEV scenarios.

3. Manual Expert Review
Automation finds common bugs; experts find critical flaws. Our senior auditors conduct line-by-line reviews focused on economic security, gas optimization, and integration risks that automated tools miss. This is where we validate the security of your core business logic.

Frequently Asked Questions
Get clear answers on our specialized security testing process, timelines, and guarantees for your smart contracts.
A full stealth testing and simulation engagement typically takes 2-3 weeks. This includes 1 week for initial setup and test suite creation, 1-2 weeks for the core adversarial simulation and exploit discovery phase, and final reporting. Complex protocols with multiple interacting contracts may extend to 4 weeks.
