✨ Belac Token Launcher v1.0 ✨

A Solana smart contract for launching SPL tokens via a bonding curve mechanism, built with native Rust and SPL.

---

Overview

Belactokenlauncher provides the on-chain foundation for creating and trading new SPL tokens using a constant-product bonding curve. Users can deploy this contract to enable:

• Fair Launch: Tokens are minted and made available for purchase directly through the curve.
• Automated Liquidity: The curve itself acts as the initial market maker.
• Configurable Trading: Buy/sell actions are mediated by the contract, with an optional, updateable trade fee.
• Path to DEX: Includes functionality designed to facilitate migrating liquidity to a standard Serum/OpenBook market and Raydium AMM pool.

This contract is developed using native Rust and the Solana Program Library (SPL), offering granular control but requiring careful implementation and client-side handling.

Features

• 🚀 SPL Token Creation: Generates a new Token Mint and associated Metaplex Metadata.
• 📈 Constant-Product Bonding Curve: Manages SOL deposits and token distribution based on virtual reserves.
• 💸 Dynamic Trade Fees: A designated authority can update the trade_fee_basis_points after deployment.
• 🔒 Migration Mechanism: Supports locking the curve and transferring locked SOL/Token liquidity (intended for backend orchestration).
• 🦀 Native Rust & SPL: No Anchor framework dependency.

Getting Started

Prerequisites

• Rust: Latest stable version recommended. Install via rustup.rs.
• Solana Tool Suite: Latest version recommended. Installation Guide.
• (Windows) WSL: Strongly recommended for building Solana programs on Windows.

Building the Contract

1. Clone the repository (if you haven't already).

2. Navigate to the contract directory:

   cd tokenlaunchcontract

3. Build the BPF bytecode:

   cargo build-sbf

   Note: If on Windows, run the build command within your WSL environment.

   The compiled program artifact will be located at target/deploy/tokenlaunchcontract.so.

Deployment

1. Prepare Deployer Wallet: Ensure you have a Solana keypair funded with SOL on your target network (Devnet, Testnet, or Mainnet).
   • Generate: solana-keygen new
   • Airdrop (Devnet/Testnet): solana airdrop 2 <YOUR_WALLET_ADDRESS> --url <NETWORK_URL>
2. Deploy:

   solana program deploy target/deploy/tokenlaunchcontract.so \
     --keypair <PATH_TO_YOUR_KEYPAIR.json> \
     --url <NETWORK_URL>

   • Replace <PATH_TO_YOUR_KEYPAIR.json> with the path to your funded deployer wallet.
   • Set <NETWORK_URL>:
     • Devnet: d or https://api.devnet.solana.com
     • Testnet: t or https://api.testnet.solana.com
     • Mainnet: m or https://api.mainnet-beta.solana.com
3. Record Program ID: The CLI will output the deployed Program ID. Save this ID – it's essential for interacting with your contract.

⚠️ Disclaimer

This smart contract is provided "as is" without warranty of any kind. It has not undergone a formal security audit. Deploying and interacting with this contract involves significant risk, especially on Mainnet with real assets.

Always conduct thorough testing and consider a professional security audit before production use.
