Crewpay

PayCrew is a Web3 crypto payroll platform designed to help companies, DAOs, and remote teams pay contributors globally in a fast, transparent, and borderless way. Instead of relying on traditional banks, PayCrew uses blockchain-based smart contracts to automate salary payments in crypto (e.g., ETH, USDC).

Team managers can add members, set payment schedules, and fund a payroll smart contract. The contract then distributes payments automatically, ensuring transparency, reducing trust issues, and eliminating intermediaries. PayCrew aims to make global hiring and payments frictionless, especially for teams in regions with limited banking infrastructure.

PayCrew is built as a full-stack Web3 application combining a smart contract backend with a modern frontend interface. The core payroll logic is implemented in Solidity smart contracts deployed on Ethereum-compatible networks. The contract stores team members, salary amounts, and payment schedules, and executes on-chain payouts in ETH or stablecoins (USDC).

The frontend is built with React/Next.js and deployed on Vercel, providing a dashboard for employers to add contributors, configure payroll settings, and trigger payments. Wallet connectivity is handled using MetaMask and WalletConnect via ethers.js.

We used Hardhat for smart contract development, testing, and deployment. On-chain data is fetched using ethers.js, and transaction history is displayed in the UI for transparency. The system is designed to be extensible for multi-chain payroll, DAO integration, and automated recurring payments using cron-like smart contract triggers.

A notable hacky aspect is the simplified payroll automation model, where employers fund a single payroll contract that programmatically distributes funds to multiple contributors in one transaction, reducing gas costs and operational friction.
