Integration Specialists — Hire Web3 Full-Stack Developer — Frontend to Smart Contract Integration Specialists
A Web3 full-stack developer bridges smart contracts and user-facing applications. They are the rarest and most in-demand engineers in the blockchain ecosystem.
React or Next.js proficiency. TypeScript. viem and wagmi for Ethereum interaction. RainbowKit or ConnectKit for wallet connection. The Graph for historical data querying.
Node.js or Python backend. Database (PostgreSQL standard). Redis for caching blockchain state. Event listener architecture (ethers.js or viem watchContractEvent). Docker and deployment experience.
Can read and understand Solidity contracts well enough to: correctly call contract functions from frontend, handle reverts gracefully in the UI, and identify when a user experience problem is a frontend bug vs smart contract behavior.
Most frontend engineers can connect to MetaMask and call balanceOf. A full-stack Web3 developer can also: design a proper off-chain indexing layer, implement real-time price feeds, handle transaction lifecycle (pending → confirmed → failed), and debug why a contract call is reverting.
Ask candidates to explain their experience with The Graph. Can they write a subgraph schema and mapping handler? This is the clearest signal of full-stack Web3 experience beyond basic wallet connection.
Common integrations: The Graph, Alchemy/Infura, OpenZeppelin Defender, and popular wallet providers.
Clarify requirements, compliance needs, architecture risks, and launch goals.
Implement core contracts, integrations, product flows, tests, and deployment automation.
Run QA, prepare audit handoff, deploy infrastructure, and support production rollout.
Schedule a discovery call and receive a tailored scope and estimate. No commitment required.
