Frequently Asked Questions

Hire Blockchain Developers: FAQs

When you hire blockchain programmers in India through SunTec India, rates typically range from USD 25 to USD 60 per hour, depending on seniority, chain expertise, and engagement model. Smart contract specialists, security-focused engineers, and Rust or Solana developers sit at the higher end of that range. We can share a detailed estimate after a short scoping call, with no hidden costs and clear monthly billing for dedicated engagements.

Every offshore blockchain developer we deploy is backed by a replacement guarantee and a senior delivery manager who tracks performance from day one. If a developer is not the right fit, we replace them within a few business days at no extra cost. Most clients see fit within the first two sprints because we match developers to your stack, time zone, and product stage before kickoff.

When you hire remote blockchain developers from us, they work in overlapping time zones with the US, UK, EU, Canada, Australia, and the Middle East, with at least a few hours of daily overlap for stand-ups, code reviews, and stakeholder calls. We use Jira, Slack, Microsoft Teams, GitHub, and Google Meet, and we mirror your existing development rituals, so there is no parallel process to manage.

You can hire blockchain experts from us on three engagement models. Dedicated team for long-running roadmaps with monthly billing, fixed price for well-scoped projects like a single smart contract suite or audit-ready dApp, and time-and-material for evolving scopes where requirements shift mid-build.

Yes. Scaling up is a planned part of the engagement, not an exception. We can add Solidity, Rust, front-end, or security engineers within a few business days from our existing bench, and onboarding is handled by the delivery manager, so your sprint velocity is not disrupted. We also flex capacity down between phases, so you only pay for the team you need.

SunTec only hires full-time blockchain developers, not freelancers, so attrition is low and managed centrally. If a developer transitions for any reason, we backfill the role within a few business days, and detailed knowledge transfer documentation is maintained from day one. Your code, repositories, and architectural decisions stay fully accessible throughout the change.

Every project follows a layered QA process. Developers write unit tests in Hardhat or Foundry, our QA team runs integration and end-to-end tests, and a separate security review uses Slither, Mythril, and manual code audits. We also run invariant testing and simulated economic attacks for DeFi protocols before any mainnet deployment. Findings are tracked in Jira with documented remediation before sign-off.

For most engagements, we onboard a dedicated blockchain development team within a few business days from contract signature. For urgent needs, a 2 or 3-engineer pod can start in as little as 5 business days using our pre-vetted bench. Onboarding includes an NDA, secure repo access, environment setup, and a kickoff workshop so the team can ship by the end of the first sprint.

Yes. Our blockchain developers run internal audits using Slither, Mythril, Echidna, and manual review against OpenZeppelin patterns and SWC registry guidance. We prepare full documentation, threat models, and test coverage reports for third-party audit firms such as CertiK, Trail of Bits, or OpenZeppelin Audits, and we own the remediation work after the findings are returned.

Yes. When you hire remote blockchain developers from us, you retain 100% ownership of source code, smart contracts, documentation, and any deployment artifacts produced during the engagement. IP transfer is built into our master service agreement, repositories live in your GitHub or GitLab from day one, and every developer signs an NDA before accessing your systems. We are ISO 27001 and CMMI Level 3 certified to back this up.
