Uniswap excels at permissionless liquidity because it operates as a foundational, chain-agnostic protocol. Its deployment across Ethereum, Arbitrum, Polygon, and other EVM chains via its V3 license-free deployment creates a massive, composable liquidity network. For example, its Ethereum mainnet deployment alone holds over $3.5B in TVL, serving as the default liquidity layer for thousands of ERC-20 tokens and DeFi protocols like Aave and Compound.
