Hire pre-vetted Blockchain Developers

BlackRock's tokenized BUIDL fund holds roughly $2.5 billion in assets as of 2026, and DTCC has already piloted tokenized trading of Russell 1000 stocks and Treasurys with BlackRock, Goldman Sachs, and JPMorgan on its digital markets infrastructure. Blockchain has moved out of the whitepaper stage and into production systems that banks, exchanges, and gaming studios ship on real deadlines, where a bug is not a bad review, it is lost funds. Finding developers who can build and secure those systems is the harder part.

Cortance connects you with pre-vetted Blockchain developers through an AI-powered matching system that reviews your requirements and returns a shortlist within 48 hours. As a European outstaffing company, we source Blockchain engineers across Europe, Latin America, and Asia, so you are not limited to whatever talent happens to be available in your own time zone. Every candidate passes our vetting process before joining, including a live protocol or code review and a reference check, so you skip the unverified Web3 freelancers and endless job-board searches. You see verified profiles and rates upfront, typically from $33 an hour for middle to senior engineers, before any interview.

Our talent pool covers Solidity, Rust, Ethereum and EVM-compatible chains, Solana, Polygon, BNB Chain, and Hyperledger, along with frameworks such as Hardhat, Truffle, Remix, Web3.js, and Ethers.js. Developers work with wallets, consensus mechanisms, Layer 2 scaling, cross-chain bridges, and cloud integrations through Infura, Alchemy, AWS, and GCP. Most engineers in the pool combine a primary EVM language with at least one secondary chain or systems language, which matters once a roadmap moves past a single-chain MVP.

Security review is part of the vetting bar, not an add-on. Smart contract engineers in our network are evaluated on vulnerability assessment, gas optimization, and upgrade patterns, on top of the DeFi protocols, exchanges, DAO infrastructure, and NFT platforms they have already shipped in production. A number of them also run AI-assisted static analysis as a first pass, catching reentrancy risks and gas inefficiencies before a human reviewer opens the file, which shortens audit turnaround on larger contracts without cutting corners on the manual review that catches what tooling misses.

Engineers behind our Blockchain bench

A handful of the people you would actually be matched with, not a stock photo team:

1. Ilya Berdar, Senior Blockchain Engineer with 6 years in the field, core skills in Solidity and Ethereum plus working Rust experience, active across DeFi protocols, smart contract architecture, and AI-driven systems, a cross-domain background that suits DeFi products with algorithmic components.
2. Alexandros Athanasopoulos, Senior Blockchain Engineer based in Greece with 7 years of experience, Solidity as a core skill alongside working Rust experience, and a background in the Blockchain and Cryptocurrency industry.
3. Oleksandr Dubyna, Verified Senior Full-stack developer with 17 years of overall engineering experience, confirmed Blockchain and Fintech industry work, and hands-on Ethereum integration inside larger product builds rather than isolated contracts.
4. Oleh Chyhrin, Blockchain Software Developer based in Kyiv, pairs a Solidity core skill with working Rust experience, useful when a build needs both EVM contracts and a non-EVM chain such as Solana in the same codebase.

Whether you are a startup preparing a token launch, a fintech or gaming company adding Web3 features, or an enterprise piloting a private ledger, we match the project to an engineer with the right background, not just the right keyword on a resume.

With Cortance, you can assemble:

1. A dedicated Blockchain team to carry a dApp, DeFi product, or NFT platform from architecture to launch.
2. A single senior smart contract engineer to design tokenomics, review protocol security, and audit existing contracts.
3. Blockchain staff augmentation to speed up delivery on a wallet, exchange, or bridge feature already in progress.

Still scoping the role itself? Our guide on how to hire a blockchain developer breaks down the four blockchain specializations and the interview rounds that actually separate production engineers from portfolio projects.
