Blockchain, Web3 y activos digitales

Ingeniería de seguridad Web3

Ingeniería de seguridad en todas las capas de Web3, desde contratos y claves hasta infraestructura e interfaces, incluidos el modelado de amenazas, la preparación de auditorías, el monitoreo y la capacidad de respuesta ante incidentes.

Panorama general

Many of the largest losses in Web3 did not come from exotic contract bugs. They came from compromised keys, poisoned frontends, misconfigured upgrades and bridges that trusted too few signers. Security has to cover the whole system, not just the Solidity.

We help teams build that coverage: threat models that span contracts and operations, key management that survives an insider threat or a stolen laptop, and monitoring that detects suspicious activity early enough to act on it.

Security engineering reviews are not a substitute for an independent third-party audit and cannot guarantee the absence of vulnerabilities. iQsolutions does not provide custody, insurance or legal services.

Aplicaciones de negocio

  1. 01

    Pre-audit hardening

    Internal security review, test-suite strengthening and static analysis ahead of an external audit, so auditors can spend their time on deep logic issues rather than findings that automated tools would have caught.

  2. 02

    Key and access management

    Design and review of multisig, MPC and HSM arrangements, signer hygiene, hardware wallet procedures and role separation for deployers, upgraders and treasury operators across the organization.

  3. 03

    Frontend and supply-chain security

    Protection against DNS hijacking, malicious dependency updates and injected scripts through content security policies, subresource integrity, dependency pinning and signed release pipelines for decentralized application frontends.

  4. 04

    Monitoring and incident response

    On-chain monitoring for anomalous transactions and governance actions, automated pause triggers where appropriate, and rehearsed incident playbooks that define who acts, how, and under which authority.

Enfoque de ingeniería

  1. 01

    System threat model

    We map assets, privileged roles, trust boundaries and external dependencies across contracts, infrastructure and people, then rank threats by likelihood and potential impact.

  2. 02

    Code and configuration review

    Manual review supported by Slither, Aderyn, Semgrep and fuzzing examines contract logic, deployment configuration, access control and upgrade paths against the threat model.

  3. 03

    Operational security review

    Signing procedures, key storage, CI/CD pipelines, cloud accounts and frontend hosting are assessed, because attackers increasingly target operations rather than contract code.

  4. 04

    Remediation support

    Findings are prioritized with clear reproduction steps and recommended fixes, and we work with your engineers until each issue is resolved, formally accepted or tracked.

  5. 05

    Detection and readiness

    Monitoring rules, alert routing and incident playbooks are implemented and exercised through tabletop drills, so the team knows exactly how to respond under pressure.

Preguntas frecuentes de los líderes

Is your security review the same as an audit?

No. We are an engineering partner, and our reviews are designed to harden systems and prepare them for audit. For contracts holding significant value, we recommend an independent audit by a specialist firm, ideally more than one, followed by a public bug bounty after launch.

What should we do first if we suspect an exploit?

Follow your incident playbook: pause affected contracts if you can, preserve evidence, notify signers through a pre-agreed secure channel and engage specialized responders. If no playbook exists, that is the most urgent gap to close, ideally long before any incident occurs.

Can you review a protocol that is already deployed?

Yes. For live systems, we compare deployed bytecode against source, examine admin roles and upgrade paths, check monitoring coverage and assess operational procedures. Findings that carry immediate risk are communicated privately to your designated contacts first.
