Blockchain Development Services
Smart contracts and distributed ledger work, audited before anything touches mainnet.
We build on-chain systems where the trust model genuinely requires one — and say so plainly when a database would serve you better. Every contract ships with tests, invariants, and an external audit path.
What the engagement includes
- Smart contract engineering — Solidity and Rust contracts written against explicit invariants.
- Security review — Internal review plus coordination with a third-party auditor before deployment.
- Wallet and key handling — Custody and signing flows designed with recovery in mind.
- Token and NFT standards — Standards-compliant implementations, with the compliance questions raised early.
- Off-chain integration — Indexers, event listeners, and reconciliation between chain state and your database.
- Honest scoping — If a centralised system fits better, we tell you before you spend the budget.

How we approach this work
Every blockchain development engagement runs on the same delivery model — the specifics below change, the discipline does not.

Process
How a project runs
- 01
Requirements
Workshops with your stakeholders to establish scope, constraints, and success criteria.
- 02
Research
User, competitor, and technical research to challenge assumptions before they become code.
- 03
Architecture
System design, integration mapping, and a written record of the trade-offs we chose.
- 04
Design
Flows, screens, and every non-happy state, delivered as a working component system.
- 05
Build
Two-week increments, each ending in something demo-able on a real environment.
- 06
Test
Automated regression plus exploratory passes under poor-network and low-end device conditions.
- 07
Launch
Staged rollout, store submission, monitoring, and a rollback plan agreed in advance.
- 08
Measure
Instrumentation reviewed against the success criteria set in step one.
- 09
Support
Maintenance retainer covering OS upgrades, dependency patching, and SLA-backed fixes.
FAQ
Blockchain Development questions
How do we start, and what does it cost?
With a Product Requirement Analysis for ₹3,500: a call with the people who will build it, your requirements worked through, and a written quotation and timeline. Pay on our Razorpay page, then pick a time at elevatebox.in/book.
How do you price engagements?
Fixed-price for well-defined scopes, and time-and-materials for evolving products. We recommend fixed-price discovery first so the build estimate is based on evidence rather than assumption.
Who owns the code and infrastructure?
You do, throughout. Repository, cloud accounts, and deployment credentials are in your name from the first commit, not transferred at the end.
How long does a typical project take?
A focused MVP is usually eight to sixteen weeks. Platform work and multi-app products run longer. We give a range with a confidence level, and narrow it as unknowns resolve.
Can you work with our existing team?
Yes. We embed in your repositories, stand-ups, and review process, or run a parallel workstream with defined interfaces — whichever fits how you already work.
What happens after launch?
A maintenance retainer covering OS and dependency upgrades, monitoring, and SLA-backed fixes. You can also take it entirely in-house — the documentation and handover support that with are included.
Do you sign NDAs and custom contracts?
Yes. We work under client MSAs and NDAs routinely, including UK, EU, UAE, and US terms, and we can complete security questionnaires as part of onboarding.
Which time zones do you cover?
We commit to a daily overlap window agreed before the contract starts. UAE and Europe get near-full overlap; US clients get a committed morning or evening window.
Will you tell us if we should not build something?
Yes, and we do. If a simpler tool or no build at all serves you better, we say so during discovery rather than after invoicing the build.
