Introduction
Uniswap's latest governance proposal plans to distribute protocol fees proportionally to staked UNI token holders, sparking an 80% price surge. The proposal underscores the practical utility of UNI by redistributing fees generated by Uniswap—second only to Ethereum in on-chain revenue. With Uniswap V4 set to launch in Q3 2024, this article explores the evolution from V3 to V4, highlighting technical upgrades and their implications for the DeFi ecosystem.
Uniswap V3: Key Features and Applications
Launched in May 2021, Uniswap V3 introduced:
- Concentrated Liquidity: Liquidity providers (LPs) can allocate assets within custom price ranges, boosting capital efficiency.
- Multiple Fee Tiers: 0.05%, 0.30%, and 1.00% options cater to varying risk levels and trading volumes.
- Layer 2 Integration: Optimism compatibility reduces gas fees and improves scalability.
- Non-Fungible Liquidity (NFL): LPs receive NFTs representing their pool shares, enabling flexible position management.
Limitations:
- High gas costs for multi-pool swaps.
- Fragmented liquidity due to separate contracts per pool.
Uniswap V4: Innovations and Improvements
Expected in Q3 2024, V4 introduces:
1. Hooks and Custom Pools
- Hooks: Smart contracts triggered at pool lifecycle stages (e.g., creation, swaps) enable dynamic fees, limit orders, and TWAMM functionality.
- Use Cases: Native oracle support, MEV resistance, and integration with lending protocols.
2. Singleton Design
- All pools managed under one contract, reducing pool creation costs by 99%.
- Enables cheaper multi-pool swaps via flash accounting (batch transactions).
3. Native ETH Trading Pairs
- Direct ETH/ERC-20 trades eliminate WETH wrapping costs (saving ~21k gas per transaction).
4. Enhanced Security
- Rigorous auditing planned—positioned as Ethereum’s "most examined code."
Comparison: V3 vs. V4
| Feature | Uniswap V3 | Uniswap V4 |
|-----------------------|-------------------------------------|-------------------------------------|
| Liquidity | Range-bound, capital-efficient | Customizable via Hooks |
| Fees | Tiered (0.05%–1.00%) | Dynamic, pool-specific |
| Gas Costs | High (per-pool contracts) | Low (singleton + flash accounting) |
| ETH Support | WETH only | Native ETH pairs |
Pros and Cons of Uniswap V4

FAQs
1. When will Uniswap V4 launch?
- Target: Q3 2024, post-Ethereum’s Cancun upgrade.
2. How do Hooks improve liquidity pools?
- They allow custom logic (e.g., dynamic fees) without modifying core protocol code.
3. Will V4 reduce gas fees significantly?
- Yes, via singleton contracts and native ETH support.
Conclusion
Uniswap V4 marks a leap forward with modular design (Hooks) and cost-efficient architecture. While its complexity may challenge casual users, the upgrade solidifies Uniswap’s role as a DeFi innovator. The recent governance vote—100% in favor—signals strong community confidence in V4’s vision.
