ERC721 Base

import "@thirdweb-dev/contracts/base/ERC721Base.sol";

The ERC721Base smart contract implements the ERC721 NFT standard, along with the ERC721A optimization to the standard. It allows you to mint NFTs to yourself (or to someone else) and selling those NFTs on a marketplace.

Functions to Override​

The following functions have been implemented on this contract & are available to be overridden to add custom logic:

tokenURI
    /**
     *  @notice         Returns the metadata URI for an NFT.
     *  @dev            See `BatchMintMetadata` for handling of metadata in this contract.

     *  @param _tokenId The tokenId of an NFT.

            return fullUriForToken;
        }

        string memory batchUri = _getBaseURI(_tokenId);
        return string(abi.encodePacked(batchUri, _tokenId.toString()));
    }
mintTo
    /**
     *  @notice          Lets an authorized address mint an NFT to a recipient.
     *  @dev             The logic in the `_canMint` function determines whether the caller is authorized to mint NFTs.
     *
     *  @param _to       The recipient of the NFT to mint.
     *  @param _tokenURI The full metadata URI for the NFT minted.

        _setTokenURI(nextTokenIdToMint(), _tokenURI);
        _safeMint(_to, 1, "");
    }
batchMintTo
    /**
     *  @notice          Lets an authorized address mint multiple NFTs at once to a recipient.
     *  @dev             The logic in the `_canMint` function determines whether the caller is authorized to mint NFTs.
     *
     *  @param _to       The recipient of the NFT to mint.
     *  @param _quantity The number of NFTs to mint.
     *  @param _baseURI  The baseURI for the `n` number of NFTs minted. The metadata for each NFT is `baseURI/tokenId`
     *  @param _data     Additional data to pass along during the minting of the NFT.

    }
burn
    /**
     *  @notice         Lets an owner or approved operator burn the NFT of the given tokenId.
     *  @dev            ERC721A's `_burn(uint256,bool)` internally checks for token approvals.
