Hire Offshore Blockchain Developers in Vietnam 🇻🇳

Every Blockchain candidate completes a multi-stage technical assessment covering Solidity, Rust (Solana), Smart Contract Security: architecture review of a sample codebase, hands-on coding exercise reflecting real Blockchain development scenarios, and a system design discussion. We evaluate code quality, testing practices, and technical communication — not just whether it works, but how maintainable and scalable the solution is. We also verify certifications such as Certified Blockchain Developer and ConsenSys Certified Ethereum Developer. Only candidates demonstrating production-level Blockchain expertise pass our vetting.

All our Blockchain developers are based in India and work schedules that provide 4-6 hours of daily overlap with US, UK, or Australian business hours. This covers standups, code reviews, pair programming, and stakeholder meetings. Complex development work happens during their extended hours, meaning you review pull requests each morning with minimal wait time. We use Hardhat, Foundry, ethers.js for asynchronous collaboration and handoffs. We've optimized this cadence across hundreds of engagements.

Every engagement is covered by a comprehensive NDA, IP assignment agreement, and data security protocols. All code, designs, and deliverables created by your Blockchain developer are your property — full IP assignment, no exceptions. Access to Hardhat, Foundry, ethers.js and other client systems is managed through role-based permissions. Our infrastructure includes VPN-only access to client environments, endpoint security on all workstations, and we can accommodate SOC 2, HIPAA, or other compliance frameworks. Background verification is standard for all candidates.

We offer a free replacement guarantee. If your Blockchain developer isn't meeting expectations, tell us and we'll source a replacement with proven expertise in Solidity, Rust (Solana), Smart Contract Security within 5 business days at no additional cost. The transition includes a structured handover: documentation of in-progress work, codebase walkthrough with the new resource, and overlap period where both are available. The replacement will be pre-screened for experience in Smart Contract Development, DeFi Protocol Development, NFT & Digital Asset Platforms. In practice, we rarely need replacements — our vetting process has a 95%+ retention rate past the first 90 days.

From your initial brief to an onboarded Blockchain developer typically takes 8-10 business days. We deliver 3-5 pre-vetted profiles with experience in Solidity, Rust (Solana), Smart Contract Security within 48 hours. You interview your shortlist, and once selected, onboarding covers environment setup, codebase walkthrough, tooling access, and first sprint planning. Most Blockchain developers submit their first meaningful pull request within the first week. Our candidates are experienced in Smart Contract Development, DeFi Protocol Development, NFT & Digital Asset Platforms use cases.

We offer three engagement models: (1) Dedicated Resource — a full-time Blockchain expert specializing in Solidity, Rust (Solana), Smart Contract Security works exclusively on your project with 40 hrs/week, daily standups, and direct communication covering areas like Smart Contract Development, DeFi Protocol Development, NFT & Digital Asset Platforms. (2) Team Extension — a managed pod (2-10 people) with tech lead, developers, QA, and optional PM for sprint-aligned delivery. (3) Project-Based — fixed scope with milestone delivery, full PM oversight, and UAT. Most clients start with a dedicated resource and scale to a team as the project grows.

Your monthly rate covers the developer's dedicated time (40 hrs/week for full-time), equipment and workstation, HR management, time tracking, and our managed services layer — which includes onboarding support, performance reviews, communication facilitation, and admin overhead. There are no hidden costs. Rate differences between seniority levels reflect experience depth in Blockchain specifically, not just years in the industry. Rate differences also reflect certification depth — Certified Blockchain Developer and ConsenSys Certified Ethereum Developer certified developers may be priced at the higher end.

Yes. Our Blockchain developers hold certifications including Certified Blockchain Developer, ConsenSys Certified Ethereum Developer. We verify certifications directly and ensure they're current. However, we weight hands-on experience alongside certifications — a certified Blockchain developer with production ships is more valuable than credentials alone.
