I need a brand-new ERC-20 smart contract built from scratch, then deployed to the Ethereum network. The token must include minting, burning, and pausable functionality, implemented with clean, upgrade-friendly Solidity code that follows current best practices (OpenZeppelin libraries, Hardhat or Foundry for testing). Please create, test, and deploy the contract, then hand over everything required for future maintenance. Deliverables • Verified Solidity source code with mint, burn, and pause modules • Full test suite covering core logic and edge cases • Deployment scripts and step-by-step notes (addresses, gas used, etherscan verification) • Final token address on Ethereum mainnet or a clearly documented test deployment if mainnet is postponed Acceptance criteria ✔ Contract passes all unit tests and is visible as “Contract Verified” on Etherscan ✔ Mint, burn, and pause functions work as intended through a simple demo script or UI ✔ Code is lint-clean and compiles without warnings under the latest stable Solidity compiler If anything is unclear, please outline your approach before coding so we keep the process smooth.

Hello, I will design a clean, upgrade-friendly ERC-20 token from scratch with mint, burn, and pause features, using OpenZeppelin libraries and tested with Hardhat. My approach is to outline the architecture, implement a minimal, well-documented contract, then build a robust test suite covering normal and edge cases, followed by deployment scripts and step-by-step notes for verification on Etherscan. I’ll provide verified Solidity sources and a demo script to show minting, burning, and pausing in action. I will ensure lint-clean code that compiles to the latest Solidity version, with clear upgrade paths and comprehensive comments for future maintenance. What is your preferred deployment target (mainnet vs testnet), and which testnet should we use if applicable? Technical questions I should ask you (important ones): 1) Do you want a mainnet deployment or strictly a testnet deployment now? 2) Which test network do you prefer (Goerli, Sepolia) if any? 3) Should we implement a proxy upgrade pattern from the start or a fixed contract? 4) Do you require a specific minting policy (role-based, initial minter)? 5) Are there any special pause behavior rules (pause only transfers, or mint/burn too)? 6) Do you need on-chain pause admin by a multisig or a single owner? 7) Any tokenomics constraints (initial supply, mint cap)? 8) Do you want to expose a simple script/UI for mint, burn, pause in the demo? 9) Etherscan verification on mainnet or testnet only, and who will own the verifier ac
