  owner: ethers.constants.AddressZero,
  createdAt: 0
}

const tx = await factory.createToken(
  metadata,
  "REFERRAL_CODE",
  { value: ethers.utils.parseEther("0.001") }
)

const receipt = await tx.wait()
const tokenAddress = receipt.events[0].args.token

​
Function Signature

function createAndBuyToken(
    TokenMetadata calldata metadata,
    string memory referral
) external payable returns (address)

​
Parameters

​
metadata
TokenMetadata
required
Same structure as createToken

​
Key Behaviors

  • More gas efficient than separate transactions
  • Initial purchase has 24-hour lock period
  • Excess ETH beyond funding goal is refunded
  • Subject to anti-snipe fees if applicable

​
Example

const metadata = {
  name: "My Token",
  ticker: "MTK",
  description: "An amazing token",
  imageUrl: "https://example.com/logo.png",
  telegram: "",
  twitter: "",
  website: "",
  owner: ethers.constants.AddressZero,
  createdAt: 0
}

const creationFee = ethers.utils.parseEther("0.001")
const purchaseAmount = ethers.utils.parseEther("0.1")
const totalValue = creationFee.add(purchaseAmount)

const tx = await factory.createAndBuyToken(
  metadata,
  "REFERRAL_CODE",
  { value: totalValue }
)

const receipt = await tx.wait()

​
Token Metadata Structure

interface TokenMetadata {
  name: string
  ticker: string
  description: string
  imageUrl: string
  telegram: string
  twitter: string
  website: string
  owner: address
  createdAt: uint40
}

​
Error Handling

  • InsufficientETH: Less than 0.001 ETH provided
  • InvalidMetadata: Missing required fields
  • ETHTransferFailed: Refund transfer failed
  • Name, ticker, description, and imageUrl are required
  • Ticker maximum 11 characters
  • Creation fee exactly 0.001 ETH
  • Owner and createdAt set by contract
Gas Optimization: Use createAndBuyToken when planning to buy immediately after creation to save ~30% on gas costs.
