ILazyMintWithTier

Thirdweb's LazyMintWithTier is a contract extension for any base NFT contract. It lets you 'lazy mint' any number of NFTs at once, for a particular tier. Here, 'lazy mint' means defining the metadata for particular tokenIds of your NFT contract, without actually minting a non-zero balance of NFTs of those tokenIds.

Methods

lazyMint

function lazyMint(uint256 amount, string baseURIForTokens, string tier, bytes extraData) external nonpayable returns (uint256 batchId)

Lazy mints a given amount of NFTs.

Parameters

Name	Type	Description
amount	uint256	The number of NFTs to lazy mint.
baseURIForTokens	string	The base URI for the 'n' number of NFTs being lazy minted, where the metadata for each of those NFTs is ${baseURIForTokens}/${tokenId}.
tier	string	The tier for which these tokens are being lazy minted. Here, tier is a unique string label that is used to group together different batches of lazy minted tokens under a common category.
extraData	bytes	Additional bytes data to be used at the discretion of the consumer of the contract.

Returns

Name	Type	Description
batchId	uint256	A unique integer identifier for the batch of NFTs lazy minted together.

Events

TokensLazyMinted

event TokensLazyMinted(string indexed tier, uint256 indexed startTokenId, uint256 endTokenId, string baseURI, bytes encryptedBaseURI)

Emitted when tokens are lazy minted.

Parameters

Name	Type	Description
tier indexed	string	undefined
startTokenId indexed	uint256	undefined
endTokenId	uint256	undefined
baseURI	string	undefined
encryptedBaseURI	bytes	undefined
