Full-Stack Crypto App Testnet Launch

Only working with people in (India,Westbengal,Kolkata) I have a working codebase that spans Python APIs and database layers, a TypeScript/React front-end, and a set of blockchain smart contracts. Before we push anything to a public testnet I want a thorough, end-to-end review. Your first task is to pull the repo, get every component running locally, and confirm that each layer talks to the others without hiccups. During that pass you must also examine security in the smart contracts, wallet actions, and user data flow, then hunt down missing features, broken functions, or gaps in the setup instructions. Only when the whole stack is solid should we move on to deployment. Once issues are fixed: • deploy the contracts to a public testnet, • hook the front-end to the new addresses, • and leave me with clean, reproducible deployment scripts plus a brief checklist that shows everything works end to end. Expect to work with Python, React, TypeScript, Solidity (or the contract language already used), Hardhat/Truffle or similar, and typical Web3 tooling. If something in the stack is unfamiliar, document the replacement you propose before changing it so I can sign off quickly.
