Web3 Full-Stack Contract Build
Budget: €36 – €0 EUR
I’m looking for an all-round Web3 developer who can take a green-field idea from concept to a live dApp. We’ll finalise the exact use-case together—anything from token issuance to a small DeFi flow or an NFT feature—so I need someone comfortable shaping requirements as well as coding.
What I need you to do
• Design and write secure Solidity smart contracts, ideally with Hardhat or Foundry.
• Create automated unit tests, linting, and deployment scripts.
• Build a modern React/Next.js front-end that talks to the contracts through ethers.js or web3.js.
• Add wallet connectivity (MetaMask, WalletConnect, etc.) and handle network switching gracefully.
• Document everything so another developer can pick it up without a hitch.
Preferred stack & skills
Solidity, Hardhat, Foundry, ethers.js, React, Next.js, TypeScript, Node, GitHub Actions. Experience with EVM chains such as Ethereum mainnet, Goerli, BNB Smart Chain, Polygon, or an L2 is essential; Polkadot knowledge is welcome but not mandatory.
Deliverables
1. Audited contract code with full test coverage.
2. Deployed contract on a chosen testnet and mainnet.
3. Responsive front-end tied to the contract.
4. README and short loom/walk-through explaining deployment and usage.
I value clean, maintainable code, proactive communication, and thoughtful advice on gas optimisation and security. When you reply, please show links to dApps you’ve shipped and mention how you’d approach the first milestone.
