What is Uniswap? A Guide to How Uniswap (UNI) Works

The majority of cryptocurrency trades occur on centralized exchanges (CEXs) and decentralized exchanges (DEXs). While CEXs require asset custody by a central authority, DEXs rely on users to provide liquidity for trading. Uniswap addresses liquidity challenges with its automated liquidity protocol, enhancing efficiency in decentralized trading.

This guide explores Uniswap’s mechanics, its distinction from traditional exchanges, and the role of its native UNI token.

What is Uniswap?

Uniswap is a decentralized exchange (DEX) built on Ethereum, supporting Layer 2 networks like Arbitrum and Optimism. It eliminates order books by pooling liquidity and using a deterministic algorithm to price assets. Traders can swap tokens seamlessly across all price ranges without liquidity shortages.

Key features:

• Automated Market Maker (AMM): Executes trades via liquidity pools in smart contracts.
• Non-custodial: Users retain full control of assets through wallets like MetaMask.
• ERC-20 Focus: Supports Ethereum-based tokens exclusively.

How Does Uniswap Work?

Uniswap operates via two smart contracts:

1. Exchange Contract: Handles token swaps.
2. Factory Contract: Adds new tokens to the platform.

Core Mechanisms:

1. Automated Liquidity Protocol: Liquidity pools replace order books, with prices calculated via pool reserves.
2. Permissionless Access: Anyone can create or join liquidity pools.
3. Liquidity Provision: Providers earn fees from trades.
4. Constant Product Formula: Maintains pool balance with the equation k = x × y (where x and y are token reserves).

Uniswap Liquidity Pools

Liquidity pools are the backbone of Uniswap. Users deposit equal values of two tokens (e.g., ETH and DAI) to form a pool.

How Pools Work:

• Initial Deposit: The first liquidity provider (LP) sets the pool’s k value.
• LP Tokens: Represent a share of the pool and can be traded or redeemed.
• Fees: Earned from trades (typically 0.3% per swap) and distributed to LPs.

Example:

• Alice deposits 10 ETH and 100 DAI (k = 10 × 100 = 1000).
• If Bob swaps 1 ETH for DAI, the pool adjusts to maintain k = 1000, updating the exchange rate.

The Uniswap (UNI) Token

What is UNI?

UNI is Uniswap’s governance token, launched in 2020 to decentralize platform decisions. Holders vote on proposals, influencing protocol upgrades.

Token Allocation:

• 60% to community members.
• 21.26% to team (4-year vesting).
• 18% to investors (4-year vesting).

Governance:

• Proposals require 1% UNI to submit and 4% to pass.
• Recent votes include fee adjustments and feature integrations.

Pricing and Arbitrage

Uniswap’s constant product formula ensures liquidity but creates arbitrage opportunities. Traders exploit price differences between Uniswap and other exchanges, aligning Uniswap’s rates with broader markets.

Benefits of Uniswap

• Low Fees: Competitive trading fees (~0.3% per swap).
• Global Access: No geographic restrictions.
• Decentralization: No intermediaries; user-controlled funds.
• DeFi Integration: Powers lending apps and other dApps.

Risks

• Impermanent Loss: LPs may lose value if token prices diverge.
• Smart Contract Risks: Potential vulnerabilities.
• Volatility: Crypto price swings affect pool values.

Uniswap Versions: V1 to V3

• V1 (2018): ETH-to-ERC-20 swaps only.
• V2 (2020): ERC-20 pairs enabled.
• V3 (2021): Introduced concentrated liquidity, allowing LPs to allocate funds to specific price ranges for higher efficiency.

Alternatives to Uniswap

• SushiSwap: Fork with yield farming.
• PancakeSwap: Binance Smart Chain-based.
• 1inch: DEX aggregator.
