ERC1155DelayedReveal

BASE: ERC1155LazyMint EXTENSION: DelayedReveal The ERC1155DelayedReveal contract uses the DelayedReveal extension. 'Lazy minting' means defining the metadata of NFTs without minting it to an address. Regular 'minting' of NFTs means actually assigning an owner to an NFT. As a contract admin, this lets you prepare the metadata for NFTs that will be minted by an external party, without paying the gas cost for actually minting the NFTs. 'Delayed reveal' is a mechanism by which you can distribute NFTs to your audience and reveal the metadata of the distributed NFTs, after the fact. You can read more about how the DelayedReveal extension works, here: https://blog.thirdweb.com/delayed-reveal-nfts

Methods

OPERATOR_FILTER_REGISTRY

function OPERATOR_FILTER_REGISTRY() external view returns (contract IOperatorFilterRegistry)

Returns

NameTypeDescription
_0contract IOperatorFilterRegistryundefined

balanceOf

function balanceOf(address, uint256) external view returns (uint256)

Get the balance of an account's Tokens.

Parameters

NameTypeDescription
_0addressundefined
_1uint256undefined

Returns

NameTypeDescription
_0uint256undefined

balanceOfBatch

function balanceOfBatch(address[] accounts, uint256[] ids) external view returns (uint256[])

Parameters

NameTypeDescription

burn

function burn(address _owner, uint256 _tokenId, uint256 _amount) external nonpayable

Lets an owner or approved operator burn NFTs of the given tokenId.

Parameters

NameTypeDescription
_owneraddressThe owner of the NFT to burn.
_tokenIduint256The tokenId of the NFT to burn.
_amountuint256The amount of the NFT to burn.

burnBatch

function burnBatch(address _owner, uint256[] _tokenIds, uint256[] _amounts) external nonpayable

Lets an owner or approved operator burn NFTs of the given tokenIds.

Parameters

NameTypeDescription
_owneraddressThe owner of the NFTs to burn.
_tokenIdsuint256[]The tokenIds of the NFTs to burn.
_amountsuint256[]The amounts of the NFTs to burn.

claim

function claim(address _receiver, uint256 _tokenId, uint256 _quantity) external payable

Lets an address claim multiple lazy minted NFTs at once to a recipient. This function prevents any reentrant calls, and is not allowed to be overridden. Contract creators should override verifyClaim and transferTokensOnClaim functions to create custom logic for verification and claiming, for e.g. price collection, allowlist, max quantity, etc.

The logic in verifyClaim determines whether the caller is authorized to mint NFTs. The logic in transferTokensOnClaim does actual minting of tokens, can also be used to apply other state changes.

Parameters

NameTypeDescription
_receiveraddressThe recipient of the tokens to mint.
_tokenIduint256The tokenId of the lazy minted NFT to mint.
_quantityuint256The number of tokens to mint.
