Stellar Meme Token Launchpad

Professional, production‑minded launchpad on Stellar, inspired by pump.fun on Solana. Create meme tokens, initialize liquidity, apply bonding curves, run fair launches, and manage distribution using Soroban smart contracts with a TypeScript backend and a modern React frontend.

Highlights

Instant Token Launches: Create token, mint, and configure launch params in one flow
Bonding Curve Sales: Optional linear/EMM curves for fair price discovery
Liquidity Bootstrap: Seed liquidity pools post‑launch (DEX integration pluggable)
Anti‑Snipe Guardrails: Per‑address caps, allowlists, cooldowns
Indexing & API: Backend indexers for project and sale state
Auditable & Modular: Soroban contracts and typed SDK clients

Tech Stack

Chain: Stellar + Soroban
Contracts: Rust with soroban-sdk
Backend: Node.js + TypeScript (Express)
Frontend: Next.js + React + TypeScript

Quickstart

Prerequisites

Node.js 18+
Rust toolchain + cargo
Soroban CLI: cargo install soroban-cli
Stellar RPC access (public testnet OK for dev)

Contracts

Build all contracts:

cd contracts
cargo build --target wasm32-unknown-unknown --release

Test (unit):

cargo test

Deploy with Soroban CLI (example, adjust network and keys):

soroban contract deploy \
  --wasm target/wasm32-unknown-unknown/release/token_launchpad.wasm \
  --source default --rpc-url https://soroban-testnet.stellar.org \
  --network testnet

Backend

cd backend
cp .env.example .env
npm install
npm run dev

Default endpoints:

GET /health
GET /projects
POST /launch (stub: validates payload)

Frontend

cd frontend
npm install
npm run dev

Open http://localhost:3000.

Contract Overview

token_launchpad:
- initialize(token_admin, name, symbol, decimals)
- create_project(creator, hard_cap, soft_cap, start_ts, end_ts, per_wallet_cap, curve_kind)
- contribute(project_id, contributor, amount)
- finalize(project_id)
- claim(project_id, contributor)
- withdraw(project_id) — for creator if soft cap not met
bonding_curve (optional):
- price(amount_in) -> amount_out
- curve config: linear/constant‑product/EMM (pluggable)

Note: Exact messages and types may change during implementation.

Security & Risk

Use testnet and small amounts first
Rate‑limit critical endpoints and require signatures where appropriate
Keep secrets out of the repo; prefer OS keychain/KMS/Vault in production
Review integer math and overflows in bonding curves carefully

Roadmap

Curve library (linear, exponential, EMM)
Project indexing and events subscription
Wallet connect (Freighter/Snaps)
DEX integration for initial liquidity
Web dashboard for monitoring launches
