FAQ: Hiring vs In-House

What is the average cost to hire Solidity developers through smartbrain.io?

At smartbrain.io, you can Hire Junior Solidity developer talent starting at USD 45-65 per hour, roughly 40 % less than Bay-Area in-house salaries when you include payroll taxes, benefits, and recruitment fees. Our transparent rate card is tiered by experience, and you pay only for productive hours, with no hidden bench or administrative costs. Because each engineer is already on contract, onboarding fees are negligible and we offer a no-risk 1-week trial.

How do you ensure IP and data security when outstaffing?

Every junior Solidity engineer signs NDA and full IP transfer agreements before engagement. Infrastructure access is scoped via VPN and role-based permissions you control. smartbrain.io is SOC 2 compliant, so code, repos, and credentials remain within your organization’s GitHub or GitLab. Audit logs are provided weekly. If you ever need an immediate replacement, we can swap talent in under 24 hours—your IP never leaves your environment.

Will time-zone differences slow collaboration?

No. We maintain talent pools across the Americas, EMEA, and APAC, so you can Hire Junior Solidity developer resources working in your core hours. Stand-ups overlap by at least four hours, and our SLA mandates <2-hour response during agreed-upon windows.

What contract terms are available?

Contracts are month-to-month with a 14-day termination clause, letting you flex capacity without long-term liability. Volume discounts start at three engineers. You can scale down to zero with no penalties, perfect for post-launch maintenance.

How rigorous is your candidate vetting process?

Candidates face a 5-stage screen: Solidity fundamentals test, gas-optimization challenge, secure coding interview, culture fit, and senior-lead code review. Only 2 % reach our client shortlist, guaranteeing production-ready code quality.

Do you offer a replacement guarantee?

Yes. If a junior Solidity hire under-performs within the first 30 days, we provide an equal or higher-rated replacement at no extra cost, typically within 48 hours.

How fast can we start once we sign the MSA?

You’ll receive your first interview slots in under 48 hours, and the chosen engineer can begin contributing code within three business days—often faster than internal onboarding.

Additional Questions

Can junior Solidity developers handle production-level smart contracts?

Yes. All juniors are paired with a senior mentor for code review and deploy only after passing our audit checklist.

What happens if project scope grows?

Simply request additional engineers; we scale teams in 48-72 hours under the same MSA.

Do you work with existing in-house teams?

Our outstaffed juniors integrate into your Slack, Jira, and Git workflows, attending your stand-ups as core contributors.

How are payments handled?

Invoices are monthly, net 15, payable via ACH, wire, or crypto stablecoin.

Is there a minimum engagement length?

One month. Most clients retain developers for 6-9 months, but you can cancel anytime with 14-day notice.

Do you provide performance reports?

Weekly velocity and code-quality dashboards keep you informed and allow data-driven adjustments.

Can we interview candidates ourselves?

Absolutely. After our vetting you may run cultural or technical interviews before finalizing.

Are there onboarding fees?

No setup fees. You only pay once work begins, backed by a one-week risk-free period.

Which project management tools do you support?

Developers are fluent with Jira, Trello, Linear, and GitHub Projects, adapting to your stack.

Will you sign our NDA?

Yes, we can execute your standard NDA or provide our template—either way, IP remains yours.
