Permissionless Token Factory

The GhostERC20Factory allows anyone to create Ghost-enabled ERC-20 tokens on Umbraline Testnet.

Factory Address

Contract	Address
GhostERC20Factory	0xb984253C697EbAd0A2221881bcD6bd65f5961ee5

Creating a Token

const FACTORY_ADDRESS = '0xb984253C697EbAd0A2221881bcD6bd65f5961ee5';

const factory = new ethers.Contract(FACTORY_ADDRESS, FACTORY_ABI, signer);

const tx = await factory.createGhostERC20(
  "My Token",                      // name
  "MTK",                          // symbol
  18,                             // decimals
  ethers.parseEther("1000000")    // initial supply
);

const receipt = await tx.wait();
// Token address from event logs

Factory ABI

const FACTORY_ABI = [
  {
    name: 'createGhostERC20',
    type: 'function',
    inputs: [
      { name: 'name', type: 'string' },
      { name: 'symbol', type: 'string' },
      { name: 'decimals', type: 'uint8' },
      { name: 'initialSupply', type: 'uint256' },
    ],
    outputs: [{ name: 'token', type: 'address' }],
    stateMutability: 'nonpayable',
  },
  {
    name: 'GhostTokenCreated',
    type: 'event',
    inputs: [
      { name: 'token', type: 'address', indexed: true },
      { name: 'creator', type: 'address', indexed: true },
      { name: 'name', type: 'string', indexed: false },
      { name: 'symbol', type: 'string', indexed: false },
    ],
  },
];

Token Features

Tokens created by the factory are automatically:

• Registered with GhostVault for vanish/summon support
• ERC-20 compliant
• Owned by the deployer

Use Cases

• Project tokens: Launch tokens with built-in privacy
• Wrapped assets: Create Ghost-enabled versions of external tokens
• Testing: Deploy test tokens for development

Getting Token Address

After creating a token, get the address from the event:

const receipt = await tx.wait();
const event = receipt.logs.find(log => {
  try {
    const parsed = factory.interface.parseLog(log);
    return parsed.name === 'GhostTokenCreated';
  } catch {
    return false;
  }
});

const tokenAddress = event.args.token;
console.log('Token deployed at:', tokenAddress);

Using the Token

Once created, the token works like any ERC-20:

const token = new ethers.Contract(tokenAddress, ERC20_ABI, signer);

// Check balance
const balance = await token.balanceOf(userAddress);

// Transfer
await token.transfer(recipient, amount);

// Vanish to GhostVault
await token.approve(VAULT_ADDRESS, amount);
await vault.vanish(tokenAddress, amount, commitment);
