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 (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.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.
