Do you arrange external audits?

We prepare the codebase and documentation for audit and coordinate with recognised audit firms; the audit itself is independent by design.

How quickly can you start?

Discovery normally begins within one to two weeks of a signed proposal, and we can run a paid discovery sprint immediately if timelines are tight.

Who owns the code and accounts?

You do — source code, cloud accounts, repositories, and analytics are yours from day one and handed over in full at any point.

Can you work alongside our in-house team?

Yes. We embed with internal teams, follow their conventions and review process, and document everything for clean handover.

Overview

What Blockchain Development means at XentraSol

Blockchain is the right tool for a narrow set of problems: shared state between parties who do not fully trust each other, provable provenance, and programmable settlement. We start by telling you honestly whether your problem is one of them.

When it is, we engineer for security above all — audited contract patterns, exhaustive test coverage, upgrade paths, and third-party audit preparation before mainnet.

Typical engagement

Discovery: 1–2 weeks
First release: 4–8 weeks
Team: Senior specialists only
Ownership: 100% yours

Business benefits

Why teams invest in this

Provable provenance

Immutable, verifiable records for supply chain, certification, and asset ownership.

Programmable settlement

Smart contracts remove reconciliation and escrow overhead between counterparties.

Security-first engineering

Audited patterns, full test coverage, and audit preparation before anything reaches mainnet.

Familiar user experience

Account abstraction and fiat on-ramps so non-crypto users can actually use the product.

Design

Flows, wireframes, and UI are validated with real users and signed off before build.

Development

Weekly increments with a live demo at the end of each one, code review, and automated tests throughout.

Testing

Functional, regression, performance, and security testing on every release candidate.

Deployment

Automated CI/CD releases, monitoring, and a controlled go-live with rollback ready.

Support

Warranty period after launch, then an optional retainer for monitoring, patching, and improvements.
