Full-Feature Crypto Presale Site

I need a modern, sleek presale website for my CRPX token that mirrors the smooth experience investors expect from today’s best launches. The smart contract is ready; what’s missing is the front-end that lets users buy, track, and later claim their tokens with zero friction.

Key functionality
• MetaMask connect / disconnect with clear status display
• Real-time refresh button that pulls on-chain data
• Countdown timer showing exact start & end dates
• Dynamic panel for Current Phase, Token Price, Allocation, and Units Sold
• Dual-currency input (BNB or USDT) that instantly previews: “You will receive X CRPX”
• Buy buttons for both currencies that call the correct contract methods
• Section showing each user’s purchased-token balance
• Claim Tokens button that appears only after the presale ends and executes claim()
• Progress bar updating the percentage sold in real time
• Toast or modal alerts for every success or error so users know what’s happening

Visual & technical notes
The interface must stay single-language and follow a clean, contemporary aesthetic: dark mode gradients, crisp typography, subtle motion. Feel free to use React + ethers.js (or a comparable stack) as long as wallet interactions are rock-solid and gas-fee estimates display correctly.

Acceptance
• Deployed demo on testnet where I can run a full buy-claim cycle
• Source code handed over, well-commented and ready for mainnet switch
• Basic README with setup instructions

If this sounds straightforward to you and you’ve shipped similar token sale dashboards before, let’s talk so we can lock in timelines and milestones.
