Erc721WithQuantitySignatureMintable.generate() method
Generate a signature that can be used to mint a dynamic NFT
Example
const nftMetadata = {
name: "Cool NFT #1",
description: "This is a cool NFT",
image: fs.readFileSync("path/to/image.png"), // This can be an image url or file
};
const startTime = new Date();
const endTime = new Date(Date.now() + 60 * 60 * 24 * 1000);
const payload = {
metadata: nftMetadata, // The NFT to mint
to: {{wallet_address}}, // Who will receive the NFT (or AddressZero for anyone)
quantity: 2, // the quantity of NFTs to mint
price: 0.5, // the price per NFT
currencyAddress: NATIVE_TOKEN_ADDRESS, // the currency to pay with
mintStartTime: startTime, // can mint anytime from now
mintEndTime: endTime, // to 24h from now
royaltyRecipient: "0x...", // custom royalty recipient for this NFT
royaltyBps: 100, // custom royalty fees for this NFT (in bps)
primarySaleRecipient: "0x...", // custom sale recipient for this NFT
};
const signedPayload = contract.signature.generate(payload);
// now anyone can use these to mint the NFT using `contract.signature.mint(signedPayload)`
Signature:
generate(mintRequest: PayloadToSign721withQuantity): Promise<SignedPayload721WithQuantitySignature>;
Parameters
Parameter | Type | Description |
---|---|---|
mintRequest | PayloadToSign721withQuantity | the payload to sign |
Returns:
Promise<SignedPayload721WithQuantitySignature>
the signed payload and the corresponding signature
Remarks
Takes in an NFT and some information about how it can be minted, uploads the metadata and signs it with your private key. The generated signature can then be used to mint an NFT using the exact payload and signature generated.
