Installation

Option 1: From npm (Recommended - Easy!)

Simply add to your OpenCode config file (~/.opencode/config.json):

{
  "plugins": ["@opencoins/launchpad-plugin"]
}

That's it! OpenCode.ai will:

• Download the plugin from npm
• Install dependencies automatically
• Use the pre-compiled code
• Ready to use immediately

No build required! 🎉

Option 2: From Source (For Development)

If you want to modify the plugin or contribute:

# Clone the repository
git clone https://github.com/singulargh/opencoins.git
cd opencoins

# Install dependencies
npm install

# Build the plugin
npm run build

Add to your OpenCode configuration file (~/.opencode/config.json):

{
  "plugins": ["file:///path/to/opencoins"]
}

Usage

🎯 Recommended: Guided Token Launch (Interactive Wizard)

The easiest way to launch a token! The wizard guides you step-by-step:

"I want to launch a token"
"Help me create a new token"
"Start the token wizard"

The AI will:

1. Ask for blockchain choice (EVM or Solana)
2. Help you select a network
3. Guide you through token parameters (name, symbol, supply)
4. Request deployment credentials
5. Ask if you want to create a liquidity pool 💧
6. Collect pool parameters (token amount, ETH/SOL amount)
7. Deploy token and create pool (if requested) 🚀

Liquidity Pool Creation

The wizard now includes an optional liquidity pool creation step:

For EVM Networks (Ethereum, BSC, Polygon, etc.):

• Automatically creates pools on Uniswap V2 and compatible DEXes
• Approves token spending and adds liquidity in one flow
• Returns pair address and LP token information

For Solana:

• Provides guidance for manual Raydium pool creation
• Displays all necessary information (mint address, amounts)
• Links to Raydium UI for easy setup

Advanced: Direct Deployment Tools

For experienced users who know exactly what they want:

Use natural language with OpenCode.ai:

Deploy an ERC-20 token called "MyToken" with symbol "MTK" and 1 million supply on Sepolia testnet

Or use the tool directly:

{
  "tool": "deploy-evm-token",
  "args": {
    "network": "sepolia",
    "name": "MyToken",
    "symbol": "MTK",
    "decimals": 18,
    "totalSupply": "1000000",
    "privateKey": "0x..."
  }
}

Response:

{
  "success": true,
  "message": "Token MyToken (MTK) deployed successfully on Sepolia Testnet",
  "tokenAddress": "0x...",
  "transactionHash": "0x...",
  "blockExplorer": "https://sepolia.etherscan.io/address/0x...",
  "network": "Sepolia Testnet",
  "deployer": "0x...",
  "feeCollector": "0x...",
  "feePercentage": "1%"
}

Deploy Solana Token

Create a Solana token named "SolToken" with symbol "SOL" and 10 million supply on devnet

Or use the tool:

{
  "tool": "deploy-solana-token",
  "args": {
    "network": "devnet",
    "name": "SolToken",
    "symbol": "SOL",
    "decimals": 9,
    "supply": "10000000",
    "keypair": "[1,2,3,...]" // JSON array from keypair file
  }
}

Get Token Information

Show me information about the token at address 0x... on Ethereum

Or:

{
  "tool": "get-token-info",
  "args": {
    "address": "0x...",
    "network": "ethereum",
    "chain": "evm"
  }
}

Supported Networks

EVM Networks

Mainnets:

• ethereum - Ethereum Mainnet
• bsc - BNB Smart Chain
• polygon - Polygon
• arbitrum - Arbitrum One
• optimism - Optimism
• base - Base

Testnets:

• sepolia - Sepolia Testnet
• bscTestnet - BSC Testnet
• mumbai - Mumbai Testnet

Solana Networks

• mainnet - Solana Mainnet Beta
• devnet - Solana Devnet
• testnet - Solana Testnet

DEX Integration & Liquidity Pools

Automated Pool Creation (EVM)

The plugin integrates with Uniswap V2 and compatible DEXes to automatically create liquidity pools:

Supported DEXes by Network:

• Ethereum: Uniswap V2
• Sepolia: Uniswap V2 Testnet
• BSC: PancakeSwap
• Polygon: QuickSwap
• Arbitrum: SushiSwap
• Optimism: SushiSwap
• Base: BaseSwap

What happens automatically:

1. ✅ Token approval for DEX router
2. ✅ Pair creation (if doesn't exist)
3. ✅ Liquidity addition with your specified amounts
4. ✅ LP tokens sent to your wallet

Requirements:

• Token balance for pool
• Native currency (ETH/BNB/MATIC) for pool
• Additional gas fees

Manual Pool Creation (Solana)

For Solana tokens, the wizard lets you choose your preferred DEX and provides guidance:

Supported DEXes:

• Raydium - Most popular, highest liquidity
• Meteora - Dynamic liquidity pools with flexible fees
• Jupiter - Aggregator with pool creation capabilities

What the wizard does:

• Asks which DEX you prefer
• Displays your token mint address
• Shows recommended amounts
• Links directly to the selected DEX's pool creation UI
• Provides step-by-step instructions

Note

Solana DEX pool creation requires OpenBook/Serum market setup (for Raydium) or other complex configurations. The wizard makes this process as easy as possible by providing all necessary information and linking to the appropriate platform.

Fee Mechanism (Launchpad Service Model)

How It Works

This plugin operates as a launchpad service. Every token deployed through this plugin automatically sends 1% of all transfers to the plugin creator as a service fee.

EVM (Ethereum, BSC, Polygon, etc.)

The deployed ERC-20 contract includes a built-in 1% transfer fee:

• Automatic Deduction: On every transfer, 1% is automatically deducted
• Fee Recipient: Sent to the plugin creator's address (hardcoded in src/config.ts)
• Cannot Be Changed: Fee recipient is immutable once contract is deployed
• Exclusions: Plugin creator can exclude specific addresses (e.g., DEX pools) if needed

Solana

Uses Token-2022's Transfer Fee Extension:

• Transfer Fee Config: 1% (100 basis points) on all transfers
• Withheld Fees: Fees are withheld in token accounts
• Fee Withdrawal: Plugin creator can withdraw accumulated fees
• Cannot Be Changed: Fee configuration is immutable once token is created
• Standard Compliant: Follows SPL Token-2022 specification

Why This Model?

The launchpad service model ensures:

• ✅ Sustainable development and maintenance of the plugin
• ✅ Professional smart contracts with security best practices
• ✅ Ongoing support and updates
• ✅ Fair compensation for providing the infrastructure

Security Considerations

Warning

Private Key Safety

• Never commit .env files to version control
• Use environment variables or secure key management
• Consider using hardware wallets for production deployments

Caution

Smart Contract Audits

• The provided contracts are templates
• Always audit contracts before mainnet deployment
• Consider professional security audits for large deployments

Important

Fee Disclosure

• Clearly communicate the 1% fee to token holders
• Consider providing fee exclusion for liquidity pools
• Ensure compliance with local regulations
