Blockchain Development Services

Architecture, contracts or chaincode, an off-chain backend, wallet-connected front ends, testing, audit preparation, deployment and monitoring are typical. A specification phase should list exactly which components you need, so quotes are comparable. Scope also depends on whether you need mobile apps, admin dashboards or integrations with payment and identity providers.

Yes. We can review and extend existing contracts, build the missing backend or interface, or add engineers to your team. We start with a code review so estimates are based on what is actually there.

Time depends on contract complexity, integrations and audit queues, not feature count alone. A discovery phase produces a milestone plan, and fixed-scope work is billed against agreed milestones, with a demo at every stage. Rough estimates before discovery are rarely reliable, so we avoid giving them.

You choose the audit firm, since independence matters. We prepare code, documentation and test evidence, answer auditor questions, fix findings and then verify each fix against the final report before launch. This keeps the audit independent and credible.
