Erc1155SignatureMintable.generate() method​

Generate a signature that can be used to mint an NFT dynamically.

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
  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 = await contract.erc1155.signature.generate(payload);
// now anyone can use these to mint the NFT using `contract.erc1155.signature.mint(signedPayload)`

Signature:

generate(payloadToSign: PayloadToSign1155): Promise<SignedPayload1155>;

Parameters​

ParameterTypeDescription
payloadToSignPayloadToSign1155the payload to sign

Returns:

Promise<SignedPayload1155>

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.
