Hire blockchain developers who build audited smart contracts, DeFi platforms, and enterprise Web3 solutions - security first, always.
In blockchain, a single contract bug can cost millions and there is no rollback. Devlex Infotech blockchain developers write Solidity and Rust with audit-grade discipline - 100% test coverage on contract logic, static analysis with Slither and Mythril, and third-party audit preparation built into every engagement. Security is not a phase; it is the process.
Our Web3 team has delivered DeFi protocols, NFT marketplaces, tokenization platforms, and private enterprise chains on Hyperledger for clients across 5+ countries. With 5+ years of engineering rigor behind every deployment, hire a dedicated blockchain developer from $3,050/month - vetted profiles shared within 24-48 hours.
ERC-20, ERC-721, ERC-1155, and custom contracts written with OpenZeppelin standards and verified with Slither, Mythril, and Foundry fuzz testing. We prepare codebases for third-party audits and remediate findings fast.
DEXs, staking protocols, lending platforms, and yield products with battle-tested oracle integrations via Chainlink. Economic attack vectors are modeled before a single line goes to mainnet.
Full marketplaces with lazy minting, royalty enforcement, and fiat on-ramps, plus real-world asset tokenization platforms. We have shipped marketplaces handling six-figure monthly volumes.
Supply chain traceability, document verification, and consortium networks on Hyperledger Fabric and Polygon Supernets. We integrate chain data with your existing ERP so adoption is frictionless.
React-based dApps with wallet connection, transaction signing, and gas-optimized UX that does not scare mainstream users. WalletConnect, account abstraction, and gasless transactions come standard.
Custodial and non-custodial wallet development with MPC key management, plus exchange API integrations and on-chain analytics. KYC/AML workflows align with FATF travel-rule requirements.
Scale up, scale down, or switch models anytime — no lock-in, no recruitment fees.

Every blockchain developer is assessed on vulnerability identification - reentrancy, oracle manipulation, access control - before touching client contracts.
Scale from one Solidity engineer to a full Web3 squad with frontend, backend, and audit-prep specialists as your protocol grows.
NDAs precede every technical discussion; contracts, tokenomics models, and code are assigned wholly to you.
5+ hours of guaranteed overlap with US and EU hours, with on-call coverage available for mainnet deployments.
Direct access to your engineers, testnet demos every sprint, and plain-English risk reports for non-technical stakeholders.
Senior Web3 talent without the recruiter premium - vetted profiles within 48 hours and no hiring fees.
From first call to onboarded developer in less than a week.
Tell us the skills, experience level, and team size you need — we respond within 24 hours.
We share hand-picked, pre-vetted developer profiles within 24–48 hours.
Interview candidates over video calls, review code samples, and run a paid trial task if you like.
Sign the NDA and agreement — your developers start within days, with full IP protection.
The frameworks, platforms, and tools our blockchain developers work with every day.
Terms that go into every agreement we sign. See all client commitments.
Every job gets a scope and a number in writing first — a fixed price for defined work, or an hourly rate with a capped estimate. If scope changes, we re-quote before we build, not after.
Source code, designs, and data are yours. We work in your repository where possible, hand over full documentation, and transfer everything at the end. No license fees, no hostage situations.
We sign your NDA — or send ours — before the first technical conversation. Your idea, your data, and your customer information stay confidential during and after the engagement.
Everything you need to know before starting your project. Still have questions? Talk to our team.
Rates start at $19/hour, with dedicated full-time blockchain developers from $3,050/month. Engagement options include Full-time (160 hrs/mo), Part-time (80 hrs/mo), and Hourly (40 hrs minimum).
Vetted profiles are shared within 24-48 hours. Most projects begin with a short architecture and threat-modeling sprint before contract development starts.
Yes, NDAs are signed before any whitepaper or tokenomics discussion, and all smart contracts, documentation, and IP transfer fully to you.
We maintain 5+ hours of daily overlap with US and EU teams and provide extended coverage windows around audits and mainnet deployments.
Free replacement within two weeks if a developer is not the right fit, with documented handover of contracts, tests, and deployment scripts.
