Protocol Overview

QuantumExchange is a decentralized exchange (DEX) built on Arc Network, utilizing the proven Uniswap V2 AMM model.

Core Components

Automated Market Maker (AMM)

QuantumExchange uses the constant product formula (x * y = k) for price discovery:

• No order books - Trades execute against liquidity pools
• Permissionless - Anyone can trade or provide liquidity
• Deterministic pricing - Prices determined by pool reserves

USDC as Native Currency

On Arc Network, USDC is the native gas token:

• Pay transaction fees in USDC
• Bridge USDC via Circle's CCTP
• Wrap to WUSDC for DEX trading
