Signature Drop

When using the Signature Drop smart contract, there is no need to provide a contract type argument, as the functionality of the smart contract is all available through the extensions interface.

The extensions that the edition contract supports are listed below.

balance​

Get the NFT balance of the connected wallet (number of NFTs in this contract owned by the connected wallet).

const balance = await contract.erc721.balance();
Configuration

Return Value​

Returns a BigNumber representing the number of NFTs owned by the connected wallet.

BigNumber;

createDelayedRevealBatch​

Create a batch of encrypted NFTs that can be revealed at a later time.

Provide an array of metadata for the NFTs you want to create, which can either be a string URL that points to metadata, or an object. The metadata must conform to the metadata standards.

If you provide an object, it is uploaded and pinned to IPFS before being lazy-minted into the contract.

// the real NFTs, these will be encrypted until you reveal them
const realNFTs = [
  {
    name: "Cool NFT #1",
    description: "This is a cool NFT",
    image: "https://example.com/image.png", // URL, IPFS URI, or File object
    // ... Any other metadata you want to include
  },
  {
    name: "Cool NFT #2",
    description: "This is a cool NFT",
    image: "https://example.com/image.png", // URL, IPFS URI, or File object
    // ... Any other metadata you want to include
  },
];
// A placeholder NFT that people will get immediately in their wallet, and will be converted to the real NFT at reveal time
const placeholderNFT = {
  name: "Hidden NFT",
  description: "Will be revealed next week!",
};
// Create and encrypt the NFTs
await contract.erc721.revealer.createDelayedRevealBatch(
  placeholderNFT,
  realNFTs,
  "my secret password",
);
Configuration

placeholder​

A single metadata object or URL string that points to valid metadata.

This is the metadata users will see until you reveal the batch.

// the real NFTs, these will be encrypted until you reveal them
const realNFTs = [
  // ...
];
// A placeholder NFT that people will get immediately in their wallet, and will be converted to the real NFT at reveal time
const placeholderNFT = {
  name: "Hidden NFT",
  description: "Will be revealed next week!",
  image: "https://example.com/image.png", // URL, IPFS URI, or File object
  //  ... Any other metadata you want to include
};
// Create and encrypt the NFTs
const txResult = await contract.erc721.revealer.createDelayedRevealBatch(
  placeholderNFT,
  realNFTs,
  "my secret password",
);

metadatas​

An array of metadata objects or URL strings that point to valid metadata.

These are the NFTs that will be revealed when you reveal the batch.

// the real NFTs, these will be encrypted until you reveal them
const realNFTs = [
  {
    name: "Cool NFT #1",
    description: "This is a cool NFT",
    image: "https://example.com/image.png", // URL, IPFS URI, or File object
    // ... Any other metadata you want to include
  },
  {
    name: "Cool NFT #2",
    description: "This is a cool NFT",
    image: "https://example.com/image.png", // URL, IPFS URI, or File object
    // ... Any other metadata you want to include
  },
];
// A placeholder NFT that people will get immediately in their wallet, and will be converted to the real NFT at reveal time
const placeholderNFT = {
  // ...
};
// Create and encrypt the NFTs
const txResult = await contract.erc721.revealer.createDelayedRevealBatch(
  placeholderNFT,
  realNFTs,
  "my secret password",
);

password​

The password that will be used to reveal the batch.

Unrecoverable

Passwords cannot be recovered or reset. If you forget your password, you will not be able to reveal your NFTs.

const realNFTs = [
  // ...
];
const placeholderNFT = {
  // ...
};
const txResult = await contract.erc721.revealer.createDelayedRevealBatch(
  placeholderNFT,
  realNFTs,
  "my secret password",
);

generate​

Generate a signature that a wallet address can use to mint the specified number of NFTs.

This is typically an admin operation, where the owner of the contract generates a signature that allows another wallet to mint tokens.

const payload = {
  to: "{{wallet_address}}", // (Required) Who will receive the tokens
  metadata: {
    name: "Cool NFT #1",
    description: "This is a cool NFT",
    image: "https://example.com/image.png", // URL, IPFS URI, or File object
    // ... Any other metadata you want to include
  },
  currencyAddress: "{{currency_contract_address}}", // (Optional) the currency to pay with
  price: 0.5, // (Optional) the price to pay for minting those tokens (in the currency above)
  mintStartTime: new Date(), // (Optional) can mint anytime from now
  mintEndTime: new Date(Date.now() + 60 * 60 * 24 * 1000), // (Optional) to 24h from now,
  primarySaleRecipient: "0x...", // (Optional) custom sale recipient for this token mint
  quantity: 100, // (Optional) The quantity of tokens to be minted
};
const signedPayload = contract.erc721.signature.generate(payload);
Configuration

The mintRequest object you provide to the generate function outlines what the signature can be used for.

The to, and metadata fields are required, while the rest are optional.

to (required)​

The wallet address that can use this signature to mint tokens.

This is to prevent another wallet from intercepting the signature and using it to mint tokens for themselves.

  metadata: {
    // ... Your NFT metadata
  },
});

metadata (required)​

Can either be a string URL that points to valid metadata that conforms to the metadata standards, or an object that conforms to the same standards.

If you provide an object, the metadata is uploaded and pinned to IPFS before the NFT(s) are minted.

const signature = await contract.erc721.signature.generate({
  quantity: "{{quantity}}",
  to: "{{wallet_address}}",
  metadata: {
    name: "Cool NFT #1",

    // ... Your NFT metadata
  },
  currencyAddress: "{{currency_contract_address}}",
});

price (optional)​

If you want the user to pay for minting the tokens, you can specify the price per token.

Defaults to 0 (free minting).

const signature = await contract.erc721.signature.generate({
  quantity: "{{quantity}}",
  to: "{{wallet_address}}",
  metadata: {
    // ... Your NFT metadata
  },
  price: "{{price}}", // The user will have to pay `price * quantity` for minting the tokens
});

mintStartTime (optional)​

The time from which the signature can be used to mint tokens.

Defaults to Date.now() (now).

const signature = await contract.erc721.signature.generate({
  quantity: "{{quantity}}",

  metadata: {
    // ... Your NFT metadata
  },
  mintStartTime: new Date(), // The user can mint the tokens from this time
});

mintEndTime (optional)​

The time until which the signature can be used to mint tokens.

Defaults to new Date(Date.now() + 1000 * 60 * 60 * 24 * 365 * 10), (10 years from now).

const signature = await contract.erc721.signature.generate({
  quantity: "{{quantity}}",
  to: "{{wallet_address}}",
  metadata: {
    // ... Your NFT metadata
  },

The typical pattern is the admin generates a signature, and the user uses it to mint the tokens, under the conditions specified in the signature.

Must be of type SignedPayload1155.

// Use the signed payload to mint the tokens
const txResult = contract.erc721.signature.mint(
  signature, // Signature generated by the `generate` function
);

mintBatch - Signature-based​

Use multiple signatures at once to mint tokens.

This is the same as mint but it allows you to provide multiple signatures at once.

// Use the signed payloads to mint the tokens
const txResult = contract.erc721.signature.mintBatch(signatures);

          price: 0.5, // Override the price this wallet pays
        },
      ],
      merkleRootHash: "0x...", // The merkle root hash of the snapshot

totalCirculatingSupply​

Get the total number of NFTs that are currently in circulation.

i.e. the number of NFTs that have been minted and not burned.

const totalSupply = await contract.erc721.totalCirculatingSupply();
Configuration

Return Value​

Returns a BigNumber.

BigNumber;

totalClaimedSupply​

Get the total number of tokens claimed from the drop so far.

const totalClaimedSupply = await contract.erc721.totalClaimedSupply();
Configuration

Return Value​

Returns a BigNumber representing the total number of tokens claimed from the drop so far.

BigNumber;

totalUnclaimedSupply​

BigNumber;
Configuration

price​

The price per token in the currency specified above.

The default value is 0.

maxClaimablePerWallet​

The maximum number of tokens a wallet can claim.

The default value is unlimited.

maxClaimableSupply​

The total number of tokens that can be claimed in this phase.

For example, if you lazy mint 1000 tokens and set the maxClaimableSupply to 100, then only 100 tokens will be claimable in this phase, leaving 900 tokens to be claimed in the next phases (if you have any).

This is useful for "early bird" use cases, where you allow users to claim a limited number of tokens at a discounted price during the first X amount of time.

startTime​

When the phase starts (i.e. when users can start claiming tokens).

The default value is immediately.

waitInSeconds​

The amount of time between claims a wallet must wait before they can claim again.

The default value is 0, meaning users can claim again immediately after claiming.

snapshot​

A list of wallets that you want to override the default claim conditions for.

Wallet addresses within this list can be set to pay in a different currency, have a different price, and have a different maximum claimable amount.

{
  address: string;
  currencyAddress?: string;
  maxClaimable?: number;
  price?: number;
}

Learn more about improved claim conditions.

merkleRootHash​

If you want to provide your own merkle tree for your snapshot, provide the merkle root hash here.

This is only recommended for advanced use cases.

resetClaimEligibilityForAll​

This means you reset any previous claim conditions that existed and allow users to claim again as if the drop had just started.

A boolean value that determines whether to reset the claim conditions or to keep the existing state.

By resetting them, any previous claims that were made will be ignored by the claim condition restrictions.

For example, if you had a limit of 1 token per wallet, and a user claimed a token, then you reset the claim conditions, that user will be able to claim another token.

Must be a boolean.

Defaults to false.

totalCount​

Get the total number of NFTs minted in this contract.

Unlike totalCirculatingSupply, this includes NFTs that have been burned.

const totalSupply = await contract.erc721.totalCount();
Configuration

Return Value​

Returns a BigNumber.

BigNumber;

update - Claim Conditions​

Update a single claim phase, by providing the index of the claim phase and the new phase configuration.

The index is the position of the phase in the list of phases you have made, starting from zero. e.g. if you have two phases, the first phase has an index of 0 and the second phase has an index of 1.

All properties of a phase are optional, with the default being a free, open, unlimited claim, in the native currency, starting immediately.

const txResult = await contract?.erc721.claimConditions.update(
  0, // Index of the claim phase to update
  {
    metadata: {
      name: "Phase 1", // The name of the phase
    },
    currencyAddress: "0x...", // The address of the currency you want users to pay in
    price: 1, // The price of the token in the currency specified above
    maxClaimablePerWallet: 1, // The maximum number of tokens a wallet can claim
    maxClaimableSupply: 100, // The total number of tokens that can be claimed in this phase
    startTime: new Date(), // When the phase starts (i.e. when users can start claiming tokens)
    waitInSeconds: 60 * 60 * 24 * 7, // The period of time users must wait between repeat claims
    snapshot: [
      {
        address: "0x...", // The address of the wallet
        currencyAddress: "0x...", // Override the currency address this wallet pays in
        maxClaimable: 5, // Override the maximum number of tokens this wallet can claim
        price: 0.5, // Override the price this wallet pays
      },
    ],
    merkleRootHash: "0x...", // The merkle root hash of the snapshot
  },
);
Configuration
See [`set`](#set) configuration for more details.

update - Contract Metadata Update the metadata of your smart contract.​

const txResult = await contract.metadata.update({
  name: "My Contract",
  description: "My contract description",
});
Configuration

metadata​

Provide an object containing the metadata of your smart contract following the contract level metadata standards. New properties will be added, and existing properties will be overwritten. If you do not provide a new value for a previously set property, it will remain unchanged. Below are the properties you can define on your smart contract.

{
  name: string; // Name of your smart contract
  description?: string; // Short description of your smart contract
  image?: string; // Image of your smart contract (any URL, or IPFS URI)
  symbol?: string; // Symbol of your smart contract (ticker, e.g. "ETH")
  external_link?: string; // Link to view this smart contract on your website
  seller_fee_basis_points?: number // The fee you charge on secondary sales, e.g. 100 = 1% seller fee.
  fee_recipient?: string; // Wallet address that receives the seller fee
}
## verify Verify that a payload is correctly signed. This allows you to provide a payload, and prove that it was valid and was generated by a wallet with permission to generate signatures. If a payload is not valid, the `mint`/`mintBatch` functions will fail, but you can use this function to verify that the payload is valid before attempting to mint the tokens if you want to show a more user-friendly error message. ```javascript // Provide the generated payload to verify that it is valid const isValid = await contract.erc721.signature.verify(payload); ```
Configuration
#### payload (required) The payload to verify. Must be of type `SignedPayload1155`. ### Return Value Returns `true` if the payload is valid, `false` otherwise. ```typescript boolean; ```
## verify - Permissions Check to see if a wallet has a set of roles. Throws an **error** if the wallet does not have any of the given roles.
const verifyRole = await contract.roles.verify(
  ["admin", "minter"],
  "{{wallet_address}}",
);
Configuration
#### roles An array of roles to check. Must be an array of `string`s.
const verifyRole = await contract.roles.verify(
  ["admin", "minter"],
  "{{wallet_address}}",
);

wallet​

The wallet address to check. Must be a string.
