We build security into every layer of your Web3 application. Architecture design, vulnerability prevention, real-time monitoring, and incident response.
Smart contract security is too often treated as an afterthought — a single audit conducted days before launch. This approach consistently fails. Real security starts at the design phase and continues through every stage of development, deployment, and operation. Arthiq provides comprehensive smart contract security services that embed protection into the foundation of your protocol.
We approach security proactively rather than reactively. Instead of finding bugs after they are written, we design architectures that prevent vulnerability classes from existing in the first place. Our security engineers work alongside development teams to establish secure coding patterns, review design decisions for security implications, and build testing infrastructure that catches issues before they reach production.
Our security practice covers the full lifecycle — threat modeling during design, secure development patterns during implementation, comprehensive testing before deployment, monitoring during operation, and incident response when needed. This holistic approach provides defense in depth that a single-point audit cannot match.
Before any code is written, we conduct threat modeling that identifies the attack surface of your protocol. We enumerate the assets that need protection (user funds, protocol treasury, governance authority), the threat actors who might target them (external attackers, malicious insiders, MEV bots), and the attack vectors they might use (direct exploitation, economic manipulation, social engineering).
From this threat model, we design security architectures with appropriate controls. This includes access control hierarchies, timelock delays on sensitive operations, rate limiting on high-value functions, circuit breakers for anomalous conditions, and upgrade mechanisms with proper safety checks.
We also design the operational security model — who holds admin keys, how multisig signers are selected and distributed, what monitoring and alerting is needed, and how incident response procedures work. This operational layer is often the weakest link in protocol security, and we address it with the same rigor we apply to smart contracts.
Our security-focused development methodology implements multiple layers of protection. We follow checks-effects-interactions pattern, use reentrancy guards, implement pull-over-push for fund distribution, validate all external inputs, and minimize attack surface by following the principle of least privilege for every function and role.
We maintain an internal vulnerability database that categorizes known attack patterns — reentrancy, oracle manipulation, flash loan exploitation, signature malleability, storage collision, access control bypass, and economic attacks. Every contract we write is reviewed against this database before it passes our internal security review.
Our testing methodology combines unit tests, integration tests, fuzz testing with Foundry, invariant testing that validates protocol properties under random operation sequences, and formal verification for critical mathematical properties. This multi-layered testing catches vulnerabilities at different abstraction levels.
Deployment is not the end of the security story. We build real-time monitoring systems that watch for unusual on-chain activity — large fund movements, unexpected function calls, abnormal parameter changes, and patterns that match known attack signatures. These systems alert operators through multiple channels and can trigger automatic defensive actions.
Our monitoring infrastructure includes transaction simulation that previews the effects of pending transactions before they are confirmed, mempool monitoring for front-running and sandwich attack detection, and oracle price deviation tracking that identifies potential manipulation. For DeFi protocols, we monitor position health, liquidation queue depth, and protocol solvency in real time.
We also build incident response playbooks that define clear procedures for different threat scenarios — how to pause the protocol, how to assess damage, how to communicate with users, and how to remediate vulnerabilities. Having these procedures documented and rehearsed before an incident occurs reduces response time and limits potential damage.
Security is not a one-time engagement — it is an ongoing commitment. We provide continuous security advisory services that include review of new code deployments, assessment of dependency updates, evaluation of new integration points, and periodic re-assessment of the protocol's threat model as it evolves.
When new vulnerability classes are discovered in the broader ecosystem, we proactively assess whether your protocol is exposed and recommend mitigations. When you plan protocol upgrades or new features, our security team reviews the design before development begins, catching potential issues at the stage where they are cheapest to fix.
Arthiq's security practice is embedded in our engineering culture — every developer on our team is trained in smart contract security, and security review is a mandatory part of our development workflow. Contact founders@arthiq.co to discuss how we can strengthen your protocol's security posture.
We embed security into every stage of your protocol's lifecycle. From design to monitoring, we protect your users and their assets.
