FAQ

Frequently asked questions

How is Blockchain Development different from a freelance hire?

You get senior, vetted engineers backed by a delivery manager, QA, DevOps, and replacement guarantees — not a single person you have to manage end-to-end.

How quickly can a team start?

Within 48 hours of sign-off we typically have an onboarded squad in standups and writing code.

Do you sign NDAs and assign IP?

Yes. Mutual NDA before any technical conversation; full IP and source-code ownership transfers to you on payment.

Can we replace a developer mid-project?

Yes — at no extra charge. We typically backfill within five business days.

What if we are not happy after the trial?

You walk away. The first 7 days are free; you only commit to engagement after you are satisfied with the team.
