Move & CosmWasm Fault Injection Testing | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process is built on audited security patterns and gas-optimized code, ensuring your protocol is both secure and cost-effective from day one.

Full Lifecycle Development: From initial design and Solidity/Rust coding to deployment on EVM/Solana and ongoing maintenance.
Security-First Approach: All code undergoes peer review and integrates OpenZeppelin libraries. We provide a clear path to third-party audits.
Measurable Outcomes: Achieve >99.9% uptime, reduce gas costs by 20-40%, and deploy a secure MVP in as little as 2-3 weeks.

We don't just write code; we deliver the foundational logic that powers your Web3 product with reliability and trust.

PROACTIVE SECURITY TESTING

Our Fault Injection Capabilities

Move beyond traditional audits. Our systematic fault injection simulates real-world adversarial conditions to expose vulnerabilities in your Move and CosmWasm smart contracts before they reach production.

State Corruption Testing

We inject faults to corrupt or manipulate contract storage, simulating scenarios like reentrancy, data races, and invalid state transitions specific to Move's linear types and CosmWasm's KV store. Identifies logic flaws that static analysis misses.

Consensus & Finality Faults

Simulate network partitions, validator downtime, and consensus failures to test your contract's behavior under Byzantine conditions. Ensures your dApp maintains correctness and availability during chain halts or forks.

Resource & Gas Manipulation

Artificially limit compute cycles, memory, and gas to trigger out-of-gas errors and resource exhaustion in Move VM and CosmWasm. Optimizes for cost efficiency and prevents denial-of-service vectors.

Oracle & External Dependency Failure

Inject delays, stale data, and malicious responses from price oracles, cross-chain bridges, and other external adapters. Validates your contract's fallback logic and error handling for critical dependencies.

Upgrade & Governance Attack Vectors

Stress-test contract upgrade mechanisms and governance proposals by simulating malicious upgrade payloads and voting manipulation. Secures the evolution of your protocol against admin key compromises.

Comprehensive Reporting & Remediation

Receive detailed, actionable reports with exploit PoCs, severity scores (CVSS), and step-by-step remediation guides. Integrates findings directly into your CI/CD pipeline for automated regression testing.

BEYOND STANDARD AUDITS

Why Proactive Fault Testing is Critical for Non-EVM Chains

Standard audits verify code logic, but they cannot simulate the unpredictable conditions of live networks. For Move and CosmWasm chains, where validator behavior, IBC packet flow, and state transitions differ fundamentally from Ethereum, proactive fault injection is the only way to guarantee resilience.

Simulate Real-World Byzantine Behavior

We inject controlled faults to model malicious validators, network partitions, and state corruption scenarios specific to Tendermint consensus and Aptos/Sui Move VMs. This exposes vulnerabilities that static analysis misses.

Prevent IBC & Cross-Chain Failures

Test the resilience of your CosmWasm contracts under IBC packet timeouts, misordered acknowledgments, and channel hijacking attempts. We ensure your cross-chain logic fails safely without asset loss.

Failure Goal

Validate State Transition Edge Cases

Move's resource model and CosmWasm's singleton storage introduce unique failure modes. We systematically test for resource double-spends, storage corruption, and module upgrade rollback vulnerabilities.

PROVEN PROCESS

Our Four-Phase Testing Methodology

Our systematic approach to fault injection ensures your Move and CosmWasm smart contracts are battle-tested against real-world failure scenarios, delivering production-ready security and reliability.

1. Threat Modeling & Scenario Design

We analyze your contract's architecture to identify critical failure points and design targeted fault scenarios, including state corruption, oracle manipulation, and validator misbehavior.

Frequently Asked Questions on Move & CosmWasm Fault Injection

Get clear, technical answers on how our fault injection service identifies critical vulnerabilities in your Move or CosmWasm protocols before they reach production.

A comprehensive fault injection engagement typically takes 2-3 weeks from kickoff to final report. This includes 1-2 weeks of active testing and 1 week for analysis, remediation guidance, and report finalization. Timeline scales with protocol complexity and the number of unique contract modules.
