Create Collection

Create Collection

The launchToken function from the Launchpad SDK is used to create collection of various types of tokens (ERC-721, ERC-1155, SoulBound, Certificate) on the blockchain. It handles public and private minting conditions based on the token type.

  _symbol,
  _maxSupply,
  price,
  _tokenURI,
  chainId,
  signer,
  contractAddress,
  env
)

📄 Parameters

• tokenType (number): Specifies the type of token to deploy. Possible values:

  • TokenType.SoulBoundPrivate (0)

  • TokenType.ERC1155Public (1)

  • TokenType.ERC1155Private (2)

  • TokenType.ERC721Public (3)

  • TokenType.ERC721Private (4)

  • TokenType.Certificate (5)

• _name (string): The name of the token/collection.

• _symbol (string): The symbol of the token (e.g., ETH, MATIC).

• _maxSupply (number | ethers.MaxUint256): Maximum token supply. Not needed for ERC 1155 as it will be set later for each NFTs.

• price (number): Minting price for ERC 721 public tokens. Set to 0 for private tokens,ERC 1155(later will set for each NFTs) and certificates.

• _tokenURI (string): URI for metadata, required only for Certificate tokens. Use an empty string for other types.

• chainId (number): The chain ID of the network where the token is deployed.

• signer (ethers.Signer): Ethers.js signer object for transaction signing.

• contractAddress (string): The address of the deployed contract.

• env (string): The environment to use (testnet or mainnet).

✅ Example Usage

1. SoulBound Private Token:

await launchToken(
  TokenType.SoulBoundPrivate,
  'MySoulBoundToken',
  'SBT',
  5000,
  0,
  '',
  1,  // Ethereum Mainnet
  signer,
  '0xContractAddress',
  undefined
);

2. ERC-1155 Public Token:

await launchToken(
  TokenType.ERC1155Public,
  'GameAssets',
  'GMA',
  0,
  0,
  '',
  137,  // Polygon Mainnet
  signer,
  '0xContractAddress',
  undefined
);

3. ERC-1155 Private Token:

await launchToken(
  TokenType.ERC1155Private,
  'PrivateAssets',
  'PVA',
  0,
  0,
  '',
  137,  // Polygon Mainnet
  signer,
  '0xContractAddress',
  undefined
);

4. ERC-721 Public Token:

await launchToken(
  TokenType.ERC721Public,
  'ArtGallery',
  'ART',
  1000, 
  ethers.utils.parseEther('0.1'), //in smallest unit of that currency
  '',
  1,  // Ethereum Mainnet
  signer,
  '0xContractAddress',
  undefined
);

5. ERC-721 Private Token:

await launchToken(
  TokenType.ERC721Private,
  'VIPArt',
  'VIP',
  200,
  0,
  '',
  1,  // Ethereum Mainnet
  signer,
  '0xContractAddress',
undefined
);
