✨ Key Features
NFT Contract
- USDT public sale (price, time, address limit)
- ERC‑2981 royalties, metadata lock, payment token timelock
- 4‑role access control
Staking & Referral Contract
- Stake any number of NFTs – O(1) removal
- Daily reward: 1% of card value (per second)
- Per‑card reward cap: 5× mint price (adjustable via timelock)
- Referrer gets extra 5% of user's claim (from pool)
- Manual claiming for staking & referral rewards
- Emergency pause, timelocked cap change, timelocked fund rescue
⚙️ How It Works
- User binds referrer (one‑time)
- User mints NFT (must have bound referrer)
- User stakes NFT – rewards accrue automatically
- User claims staking rewards → referrer gets 5% extra
- Referrer claims referral rewards manually
Each NFT has its own reward pool: total reward cap = mintPrice × 5.
🛡️ Admin Controls
- Set price, sale time, address limit
- Lock metadata, change payment token (2‑day timelock)
- Pause staking, adjust reward cap (2‑day timelock)
- Emergency withdraw USDT (2‑day timelock)
- Deposit reward USDT
