Test task for Uddug

Used Libraries

• ERC721Enumerable: Enhances our contract with the ability to enumerate NFTs directly, facilitating the retrieval of total supply and individual token enumeration without additional coding.
• Ownable: Integrates ownership management functionality, ensuring that only the owner can execute certain transactions.
• ECDSA and MessageHashUtils: These libraries are employed to implement signature verification. This feature is crucial for enabling backend signature minting, enhancing security and integrity.

Core Functions

• mint: This function allows users to mint up to three NFTs per transaction an unlimited number of times. Alternatively, users can mint a set of six NFTs in a single transaction.
• signedMint: Designed for backend signature minting, this function permits the minting of one NFT, typically reserved for pre-mint by an allowlist.
• verifyAddressSigner: A utility function that verifies the signer of a signature for signedMint, ensuring the authenticity of minting requests.
• withdraw: Enables the contract owner to withdraw funds accumulated from the sale of NFTs, transferring the balance to their address.
