Clanker SDK

Deploy production-ready ERC20 tokens with built-in liquidity pools using the official Clanker TypeScript SDK.

Overview

Clanker is a token deployment protocol that creates ERC20 tokens with Uniswap V4 liquidity pools in a single transaction. The SDK provides a TypeScript interface for deploying tokens with advanced features like vesting, airdrops, and customizable reward distribution.

Quick Start

Installation

npm install clanker-sdk viem
# or
yarn add clanker-sdk viem
# or
pnpm add clanker-sdk viem

Environment Setup

Create a .env file with your private key:

PRIVATE_KEY=0x...your_private_key_here

Basic Token Deployment

import { Clanker } from 'clanker-sdk';
import { createPublicClient, createWalletClient, http, type PublicClient } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { base } from 'viem/chains';

const PRIVATE_KEY = process.env.PRIVATE_KEY as `0x${string}`;
const account = privateKeyToAccount(PRIVATE_KEY);

const publicClient = createPublicClient({
  chain: base,
  transport: http(),
}) as PublicClient;

const wallet = createWalletClient({
  account,
  chain: base,
  transport: http(),
});

const clanker = new Clanker({ wallet, publicClient });

const { txHash, waitForTransaction, error } = await clanker.deploy({
  name: 'My Token',
  symbol: 'TKN',
  image: 'ipfs://bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi',
  tokenAdmin: account.address,
  metadata: {
    description: 'My awesome token',
  },
  context: {
    interface: 'Clanker SDK',
  },
  vanity: true,
});

if (error) throw error;

const { address: tokenAddress } = await waitForTransaction();
console.log('Token deployed at:', tokenAddress);

Core Capabilities

1. Token Deployment

Deploy tokens with full customization including metadata, social links, and pool configuration.

Basic deployment:

• Token name, symbol, and image (IPFS)
• Description and social media links
• Vanity address generation
• Custom pool configurations

Reference: references/deployment.md

2. Vault (Token Vesting)

Lock a percentage of tokens with lockup and vesting periods:

vault: {
  percentage: 10,           // 10% of token supply
  lockupDuration: 2592000,  // 30 days cliff (in seconds)
  vestingDuration: 2592000, // 30 days linear vesting
  recipient: account.address,
}

Reference: references/vesting.md

3. Airdrops

Distribute tokens to multiple addresses using Merkle tree proofs:

import { createAirdrop, registerAirdrop } from 'clanker-sdk/v4/extensions';

const { tree, airdrop } = createAirdrop([
  { account: '0x...', amount: 200_000_000 },
  { account: '0x...', amount: 50_000_000 },
]);

// Include in deployment
airdrop: {
  ...airdrop,
  lockupDuration: 86_400,  // 1 day
  vestingDuration: 86_400, // 1 day
}

Reference: references/airdrops.md

4. Rewards Configuration

Configure trading fee distribution:

rewards: {
  recipients: [
    {
      recipient: account.address,
      admin: account.address,
      bps: 5000,      // 50% of fees
      token: 'Both',  // Receive both tokens
    },
    {
      recipient: '0x...',
      admin: '0x...',
      bps: 5000,      // 50% of fees
      token: 'Both',
    },
  ],
}

Token Type Options

Choose which tokens each recipient receives from trading fees:

Default Bankr Interface Fee

When deploying via Bankr, use this default rewards configuration with 20% interface fee:

// Bankr interface fee recipient
const BANKR_INTERFACE_ADDRESS = '0xF60633D02690e2A15A54AB919925F3d038Df163e';

rewards: {
  recipients: [
    {
      recipient: account.address,           // Creator
      admin: account.address,
      bps: 8000,                            // 80% to creator
      token: 'Paired',                      // Receive paired token (WETH)
    },
    {
      recipient: BANKR_INTERFACE_ADDRESS,   // Bankr interface
      admin: BANKR_INTERFACE_ADDRESS,
      bps: 2000,                            // 20% to Bankr
      token: 'Paired',                      // Receive paired token (WETH)
    },
  ],
}

Reference: references/rewards.md

5. Dev Buy

Include an initial token purchase in the deployment:

devBuy: {
  ethAmount: 0.1,           // Buy with 0.1 ETH
  recipient: account.address,
}

6. Custom Market Cap

Set initial token price/market cap:

import { getTickFromMarketCap } from 'clanker-sdk';

const customPool = getTickFromMarketCap(5); // 5 ETH market cap

pool: {
  ...customPool,
  positions: [
    {
      tickLower: customPool.tickIfToken0IsClanker,
      tickUpper: -120000,
      positionBps: 10_000,
    },
  ],
}

Reference: references/pool-config.md

7. Anti-Sniper Protection

Configure fee decay to protect against snipers:

sniperFees: {
  startingFee: 666_777,    // 66.6777% starting fee
  endingFee: 41_673,       // 4.1673% ending fee
  secondsToDecay: 15,      // 15 seconds decay
}

Contract Limits & Constants

Supported Chains

Post-Deployment Operations

Claim Vaulted Tokens

const claimable = await clanker.getVaultClaimableAmount({ token: TOKEN_ADDRESS });

if (claimable > 0n) {
  const { txHash } = await clanker.claimVaultedTokens({ token: TOKEN_ADDRESS });
}

Collect Trading Rewards

// Check available rewards
const availableFees = await clanker.availableRewards({
  token: TOKEN_ADDRESS,
  rewardRecipient: FEE_OWNER_ADDRESS,
});

// Claim rewards
const { txHash } = await clanker.claimRewards({
  token: TOKEN_ADDRESS,
  rewardRecipient: FEE_OWNER_ADDRESS,
});

Update Token Metadata

const metadata = JSON.stringify({
  description: 'Updated description',
  socialMediaUrls: [
    { platform: 'twitter', url: 'https://twitter.com/mytoken' },
    { platform: 'telegram', url: 'https://t.me/mytoken' },
  ],
});

const { txHash } = await clanker.updateMetadata({
  token: TOKEN_ADDRESS,
  metadata,
});

Update Token Image

const { txHash } = await clanker.updateImage({
  token: TOKEN_ADDRESS,
  image: 'ipfs://new_image_hash',
});

Common Workflows

Simple Memecoin Launch

1. Prepare token image (upload to IPFS)
2. Deploy with basic config (name, symbol, image)
3. Enable vanity address for memorable contract
4. Share contract address

Community Token with Airdrop

1. Compile airdrop recipient list
2. Create Merkle tree with createAirdrop()
3. Deploy token with airdrop extension
4. Register airdrop with Clanker service
5. Share claim instructions

Creator Token with Vesting

1. Deploy with vault configuration
2. Set lockup period (cliff)
3. Set vesting duration
4. Claim tokens as they vest

Best Practices

Security

1. Never expose private keys - Use environment variables
2. Test on testnet first - Verify configs before mainnet
3. Simulate transactions - Use *Simulate methods before execution
4. Verify addresses - Double-check all recipient addresses

Token Design

1. Choose meaningful names - Clear, memorable token identity
2. Use quality images - High-res, appropriate IPFS images
3. Configure vesting wisely - Align with project timeline

Gas Optimization

1. Use Base or Arbitrum - Lower gas fees
2. Batch operations - Combine when possible
3. Monitor gas prices - Deploy during low-traffic periods

Troubleshooting

Common Issues

• "Missing PRIVATE_KEY" - Set environment variable
• "Insufficient balance" - Fund wallet with native token
• "Transaction reverted" - Check parameters, simulate first
• "Invalid image" - Ensure IPFS hash is accessible

Debug Steps

1. Check wallet balance
2. Verify chain configuration
3. Use simulation methods
4. Check transaction on block explorer
5. Review error message details

• NPM : npmjs.com/package/clanker-sdk
• Examples : github.com/clanker-devco/clanker-sdk/tree/main/examples/v4

💡 Pro Tip : Always use the vanity: true option for memorable contract addresses.

⚠️ Security : Never commit private keys. Use .env files and add them to .gitignore.

🚀 Quick Win : Start with the simple deployment example, then add features like vesting and rewards as needed.
