[PoulavBhowmick03]

Title: Achievement-Based NFT Rewards
Description
Create ERC721 contract for minting achievement badges.

Acceptance Criteria:

• Mints NFTs for:
  • Top 3 finishes
  • Season-long achievements
  • Special events
• Stores metadata on IPFS
• Allows badge upgrades

Technical Details:

#[starknet::contract]
mod NFTRewards {
    use starknet::ContractAddress;

    #[storage]
    struct Storage {
        // ERC721 state
        _name: felt252,
        _symbol: felt252,
        _owners: LegacyMap<u64, ContractAddress>,
        _token_uris: LegacyMap<u64, felt252>
    }

    #[external(v0)]
    fn mint_achievement(
        ref self: ContractState,
        to: ContractAddress,
        achievement_type: u8,
        metadata_cid: felt252
    ) {
        assert(get_caller_address() == self.minter.read(), 'Unauthorized');
        let token_id = self._next_id.read();
        self._mint(to, token_id);
        self._token_uris.write(token_id, metadata_cid);
    }
}

Notes:

• Implement ERC721 metadata extension
• Add achievement tier system
• Test batch minting
