Hire pre-vetted Blockchain Developers

BlackRock's tokenized BUIDL fund crossed $2.9 billion in assets across eight blockchains within its first year, and Wall Street firms including Goldman Sachs and JPMorgan are now piloting tokenized securities trading through the DTCC. Blockchain has moved out of the whitepaper stage and into production systems that banks, exchanges, and gaming studios ship on real deadlines. 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 in our network passes a technical screening, a live protocol or code review, and a reference check before joining, 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.

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.

Where our developers have shipped

1. Cross-chain infrastructure. Our developers' portfolio includes a token bridge platform that moves assets between blockchain networks, combining frontend, backend microservices, and on-chain smart contracts to keep transfers secure.
2. NFT marketplaces. Our team has delivered a large-scale marketplace where users browse, buy, and manage digital assets, pairing blockchain logic with a conventional payment layer for a smooth checkout.
3. Tokenization and RWA platforms. Our expertise includes a Web3 infrastructure product for compliant tokenization of real-world and digital assets, plus a no-code builder that let non-developers deploy blockchain applications and design their own tokens.
4. DeFi and trading systems. Our developers' portfolio includes proprietary trading infrastructure that scans decentralized exchanges for arbitrage opportunities and simulates execution before capital moves.
5. Gaming and collectibles. Our team has built an NFT-based collectible ecosystem with smart contracts handling minting, breeding mechanics, and asset transfers.
6. Decentralized storage. Our expertise includes an S3-compatible cloud storage product with cryptographic audit trails and built-in ransomware protection.

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 developers who have already solved a similar problem.

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.

Share your requirements, and Cortance will send a shortlist of matched Blockchain developers, ready to start within days.
