Hire pre-vetted Web3 Developers

Roughly 23,000 developers actively build in Web3 worldwide, according to Electric Capital's 2025 Developer Report, and in-house senior Solidity engineers now command $250K to $400K in base pay. Most product teams do not need a full-time hire at that price to ship a dApp, audit a contract, or add on-chain logic to an existing product. They need a vetted Web3 engineer, matched to the specific chain and scope in front of them, without a six-week search.

Why Vetting Carries More Weight in Web3 Hiring

A backend bug ships a patch on Monday. A smart contract bug that reaches mainnet often cannot be fixed at all, only worked around after funds are already at risk. That is why Cortance runs Web3 candidates through a technical screen built for chain work: gas-cost reasoning, security-pattern review, and questions about a real vulnerability they caught before deployment, not just a Solidity syntax check. Roughly one in five candidates clears our Web3 vetting process, so the profiles you see have already survived the part of hiring that normally eats weeks.

What Kind of Web3 Work Have Our Engineers Shipped?

Our Web3 bench has built past the tutorial stage, into contracts and platforms that real users and real funds depended on.

Daniel Zarzecki, one of our Blockchain and Backend Engineers, founded and built WorkPod, an EVM security audit marketplace where protocol and dApp teams could scope an audit, share their codebase privately, compare proposals from independent auditors, and release payment only once the work was delivered. It turned a process most teams still run over Telegram threads and spreadsheets into a structured marketplace, the same security-first thinking we look for before any contract of ours reaches mainnet.

Other production work from the same bench:

1. Alexandros Athanasopoulos, Senior Blockchain Engineer, built the smart contracts behind KittieFight, an Ethereum dApp that turned CryptoKitties NFTs into a play-to-earn battle game, translating each cat's on-chain traits into live combat stats.
2. Ilya Berdar, Senior Blockchain Engineer, built proprietary DeFi trading infrastructure that scanned decentralized exchanges for arbitrage opportunities and simulated execution profitability before a single trade moved real funds.

The Stack Our Web3 Developers Actually Use

Solidity and Rust cover most smart contract work: Solidity for Ethereum and EVM-compatible chains, Rust for Solana, paired with Web3.js or Ethers.js and a TypeScript or Node.js layer for the dApp frontend that talks to the chain. Chain coverage matters as much as language depth. Our engineers have shipped on Ethereum, Polygon, BNB Chain, Solana, Avalanche, and L2 networks like Arbitrum and Optimism, plus non-EVM work on the XRP Ledger. A few go past the contract layer entirely: Daniel's work at an AI-focused Web3 studio included building AI agent harnesses and distributed LLM evaluation infrastructure, the kind of work that matters more each quarter as teams start wiring autonomous agents into on-chain logic instead of just static contracts.
