Clanker Skill

Deploy ERC20 tokens on Base using the Clanker protocol with built-in Uniswap V4 liquidity pools.

Setup

1. Configuration

Create a config file at ~/.clawdbot/skills/clanker/config.json:

{
  "mainnet": {
    "rpc_url": "https://1rpc.io/base",
    "private_key": "YOUR_PRIVATE_KEY"
  },
  "testnet": {
    "rpc_url": "https://sepolia.base.org",
    "private_key": "YOUR_TESTNET_PRIVATE_KEY"
  }
}

Security: Never commit your private key to version control. Use environment variables or a separate config file outside the repo.

2. Get Testnet ETH

For Base Sepolia testing, get free ETH from:

• https://cloud.base.org/faucet
• https://sepoliafaucet.com

Note: Faucet access may require:

• MetaMask or similar wallet installed
• Social login (GitHub, Twitter, etc.)
• Limited to 1-2 requests per day

3. Install Dependencies (for deployment)

For token deployment, install web3 Python package:

pip install web3

For read-only operations, only curl, jq, and python3 are required.

Usage

Deploy a Token (Mainnet)

clanker.sh deploy "My Token" MYT 0.1

Deploys an ERC20 token with 0.1 ETH initial liquidity on Uniswap V4.

Check Deployment Status

clanker.sh status <txhash>

Check if a deployment transaction was successful.

Get Token Info

clanker.sh info <token-address>

Returns token name, symbol, total supply, and other details.

Find Tokens by Deployer

clanker.sh get-token <deployer-address>

Find all tokens deployed by a specific address.

Deploy to Testnet (Sepolia)

clanker.sh testnet-deploy "Test Token" TST

Deploy to Base Sepolia testnet for testing.

Using Testnet Network

All commands support --network testnet flag:

# Check testnet status
clanker.sh status 0x1234... --network testnet

# Get testnet token info
clanker.sh info 0xabcd... --network testnet

# Find testnet tokens by deployer
clanker.sh get-token 0xdef0... --network testnet

Commands Reference

Command	Description	Parameters
deploy	Deploy token on mainnet	<name> <symbol> <initial-lp-eth>
testnet-deploy	Deploy to Sepolia testnet	<name> <symbol>
status	Check deployment status	<txhash>
info	Get token information	<token-address>
get-token	Find tokens by deployer	<deployer-address>

Examples

# Deploy a meme coin
./clanker.sh deploy "Base Dog" BDOG 0.05

# Check if deployment succeeded
./clanker.sh status 0x1234...5678

# Get info about a known token
./clanker.sh info 0xabcd...1234

# Find who deployed a token
./clanker.sh get-token 0xdef0...9876

# Test on Sepolia
./clanker.sh testnet-deploy "Test Meme" TMEME
./clanker.sh status 0xtxhash... --network testnet

Testing Guide

Step 1: Set Up Testnet Config

# Create config with testnet private key
cat > ~/.clawdbot/skills/clanker/config.json << 'EOF'
{
  "testnet": {
    "rpc_url": "https://sepolia.base.org",
    "private_key": "YOUR_TESTNET_PRIVATE_KEY"
  }
}
EOF

Step 2: Get Testnet ETH

1. Visit https://cloud.base.org/faucet
2. Connect your wallet (MetaMask)
3. Request test ETH (0.001-0.01 ETH should be enough)

Alternative faucets:

• https://sepoliafaucet.com
• https://faucet.paradigm.xyz

Step 3: Deploy a Test Token

# Deploy on testnet with 0.001 ETH initial liquidity
./clanker.sh testnet-deploy "Test Token" TST

Or with initial liquidity:

./clanker.sh deploy "Test Token" TST 0.001 --network testnet

Step 4: Verify Deployment

1. Check transaction status:

   ./clanker.sh status <txhash> --network testnet
   

2. Get token info:

   ./clanker.sh info <token-address> --network testnet
   

3. View on explorer:

   • Open https://sepolia.basescan.org/tx/\<txhash>
   • View token contract at https://sepolia.basescan.org/token/\<token-address>

Troubleshooting

Transaction failed?

• Check if you have enough ETH for gas
• Verify the Clanker factory contract is available on Sepolia
• Check network connectivity

Cannot get testnet ETH?

• Try alternative faucets
• Wait 24 hours between requests
• Check if wallet is connected correctly

Private key errors?

• Ensure key doesn't have "0x" prefix (or remove it if present)
• Check config file syntax is valid JSON

Test Results

Read-Only Operations ✅

Command	Network	Result
info (WETH)	mainnet	✅ Works - Shows correct name, symbol, supply
get-token	mainnet	✅ Works - Returns deployer stats
status	mainnet	✅ Works - Handles pending/not found tx

Deployment ⚠️

Feature	Status	Notes
Python deployment helper	⚠️ Placeholder	Requires Clanker factory address
Web-based deployment	✅ Recommended	Use https://clanker.world
Direct contract call	🔲 Not implemented	Would need factory ABI

Note: Full deployment requires the actual Clanker factory contract address on Base Sepolia. The protocol is relatively new, and contract addresses may change. For production deployment, check the official documentation.

Security Best Practices

1. Never commit private keys to version control
2. Use separate keys for testnet and mainnet
3. Test on Sepolia first before mainnet deployment
4. Verify contract addresses on official Clanker documentation
5. Start with small ETH amounts for initial liquidity
6. Monitor deployed tokens for unusual activity

• Base Sepolia Explorer: https://sepolia.basescan.org

Notes

• All deployments create tokens with built-in Uniswap V4 LP
• Initial LP ETH is required for liquidity bootstrapping
• Testnet deployments are free (no real funds, requires testnet ETH)
• Deployment may fail if Clanker contract is not available
• Check network connectivity if operations timeout
