This repo contains examples demonstrating how to create and interact with bonding curve tokens on Ethereum or any EVM-compatible chain. Use bonding curves to price tokens based on supply, eliminating the need for traditional liquidity pools.

• How to implement bonding curve pricing in Solidity
• Understanding linear bonding curves and price discovery
• Building a React/Next.js interface for token trading
• Connecting smart contracts to web interfaces using Next.js

• Node.js (v18 or later)
• Foundry for smart contract development
• Git

Navigate to the contracts/ directory to work with the Solidity contracts:

cd contracts

Install dependencies:

forge install

Run tests:

forge test

For detailed contract documentation, see contracts/README.md.

Navigate to the ui/ directory to work with the React application:

cd ui

Install dependencies:

npm install

Start development server:

npm run dev

Open http://localhost:3000 to view the application.

A bonding curve is a mathematical function that determines token price based on supply. Unlike traditional markets where price is set by supply and demand, bonding curves provide algorithmic price discovery.

• No Liquidity Pools: Tokens can be traded without external liquidity providers
• Fair Pricing: Everyone pays the same price for the same amount of tokens
• Continuous Trading: Buy and sell tokens at any time
• Price Predictability: Calculate exact costs before trading
• Bootstrap Liquidity: Create liquid markets from day one
