Introduction
The Uniswap protocol is a peer-to-peer system designed for exchanging cryptocurrencies (ERC-20 tokens) on the Ethereum blockchain. Implemented as non-upgradable smart contracts, it emphasizes censorship resistance, security, and self-custody, operating without trusted intermediaries that could restrict access.
Evolution of Uniswap
- v1 & v2: Open-source under GPL, foundational AMM design.
- v3: Introduced concentrated liquidity for capital efficiency.
- v4: Features singleton pool architecture and hooks for customizable pool behavior.
Each version functions perpetually on Ethereum, ensuring 100% uptime.
Uniswap Protocol vs. Traditional Markets
Automated Market Makers (AMMs) vs. Order Books
| Feature | Order Book Exchanges | Uniswap AMM |
|------------------|----------------------|-------------|
| Liquidity | Buyer/seller orders | Pool-based |
| Price Discovery | Market orders | Algorithmic (CFMM) |
| Efficiency | High latency | Continuous liquidity |
Key Innovations:
- Concentrated liquidity (v3): LPs allocate capital within custom price ranges.
- Hooks (v4): Enable dynamic adjustments like fee tiers or limit orders.

Permissionless Design
- Open access: No restrictions based on geography or identity.
- Immutability: Contracts cannot be altered or paused.
- Fee governance: Swap fees (10–25%) can be directed via decentralized governance.
Advanced Features
v3: Concentrated Liquidity
LPs maximize capital efficiency by focusing liquidity around current prices.
v4: Singleton Pools & Hooks
- Singleton architecture: Reduces gas costs by consolidating pools.
- Hooks: Smart contracts that modify pool behavior (e.g., TWAP oracles).

FAQs
Q: How does Uniswap ensure price accuracy?
A: Prices adjust algorithmically via the constant product formula (x*y=k), with v3/v4 enhancements for tighter spreads.
Q: Can Uniswap be shut down?
A: No—the protocol is immutable and decentralized, with no admin controls.
Q: What’s the role of UNI tokens?
A: UNI governs fee structures and protocol upgrades via votes.
Q: How does v4 reduce gas fees?
A: Singleton pools minimize contract deployments, cutting Ethereum transaction costs.
