I need a solid ERC-20 smart contract that supports on-demand minting and follows best-practice security patterns (OpenZeppelin, upgradable proxies or other proven approaches you’re comfortable with). Alongside the contract, I want a lightweight web dApp that lets users connect with MetaMask, view total supply, and call the mint function in a single, smooth flow. A clean React or [login to view URL] front end with [login to view URL] is fine; if you prefer Vue or another modern stack, I’m open as long as the UX is clear and responsive. Key acceptance criteria: • Verified, optimised Solidity code deployed on Ethereum mainnet (testnet first for review). • Minting controlled by owner role, with events properly emitted. • Front-end fully wired to the contract, wallet-connect ready, and deployed to a public URL. • Full hand-over of source (Solidity, front-end, and deployment scripts). Once we agree on milestones I’ll supply the token name, symbol, and any branding assets for the UI.

Hey — saw your post about building a solid ERC-20 token with on-demand minting. The biggest issue I see with these contracts is ensuring minting controls can’t be exploited. Quick question before I suggest an approach: do you want minting to be permissioned only to certain addresses, or fully decentralized? I’ve built and audited several ERC-20 tokens with secure minting functions, so I know how to avoid common pitfalls. If you send your detailed requirements or any specs, I’ll review them and share how to make this both secure and flexible.

I can develop a secure ERC-20 smart contract with on-demand minting capabilities, ensuring it adheres to the latest best practices in security and efficiency. I have built several token contracts and dApps that are audited and deployed on Ethereum mainnet, focusing on robust and compliant code. My approach includes writing clean, well-documented Solidity code, conducting thorough testing, and implementing access controls to protect minting functions. I will also assist with integration into your dApp frontend if needed. Are you looking for full dApp development alongside the contract, or just the smart contract itself?

⭕ Should minting remain owner-only, or do you need separate minter and admin roles? ⭕ Is upgradeability required, and should total supply have a fixed cap? A safe release depends on locking the token rules before selecting a proxy pattern. Main risks are role misconfiguration, unlimited mint exposure, chain mismatch, and failed wallet transactions. I would test permissions, events, deployment scripts, gas use, and MetaMask state handling on testnet first. Ready to keep the mainnet rollout controlled.
