We provide comprehensive Web3 services tailored to your unique requirements in the ever-evolving blockchain landscape. Our core services include Web3 Development (custom software, mobile apps, dApps, and smart contracts), Web3 Security (smart contract auditing, digital asset assessment, penetration testing, and DApp audits), and Web3 Consulting (software development consulting, Web3 transformation, ISO27001 certification, MiCAR compliance, and project management).

Initiating your journey is a seamless process. Contact us via e-mail or book a consultation directly. We'll arrange an initial consultation to understand your unique requirements, goals, and project scope. Our experts will then create a customized quote tailored to your needs.

Yes. Softstack's software development team builds smart contracts, dApps, mobile clients, and full-stack Web3 systems, from architecture through production. We often pair builds with security reviews so one German team covers delivery and assurance.

We employ a multi-faceted approach: Smart Contract Auditing to identify vulnerabilities, Digital Asset Assessment to mitigate custody and investment risks, Penetration Testing to detect infrastructure weaknesses, dApp Audits to uncover application vulnerabilities, and Ongoing Monitoring to address new threats as they emerge.

Consulting covers Web3 strategy, digital asset regulation (including MiCA), ISO 27001 / ISMS, software development advisory, Web3 integration for enterprises, and project management. We also run the Service Partner Program for VCs and platforms that need a trusted delivery partner.

The timeframe varies based on the complexity and scope of your project. One significant factor is the size and intricacy of your smart contract code. We prioritize thoroughness and accuracy in our security assessments and will provide a more precise estimate based on your project's requirements during the initial consultation.

We take data confidentiality and protection with the utmost seriousness. Our commitment is reflected in our ISO27001 certification, issued by TÜV SÜD Management Service GmbH. This certification signifies that we have established and applied an Information Security Management System (ISMS) following the highest standards of security and privacy.
