Tools: Uniswap

Uniswap is a decentralized exchange (DEX) allowing users to swap ERC-20 tokens without intermediaries. It's the backbone of DeFi, running on smart contracts and liquidity pools.

Uniswap is the OG DEX on Ethereum, letting users swap ERC-20 tokens permissionlessly by interacting directly with smart contracts.
Instead of order books, Uniswap uses an automated market maker (AMM) model where liquidity providers deposit token pairs into pools, and traders swap against those pools.

Uniswap has expanded to multiple versions (v2, v3) and even deployed on layer-2 solutions like Optimism and Arbitrum for cheaper, faster transactions. Beyond swaps, users can earn yield by providing liquidity (but watch for impermanent loss). Uniswap is one of the safest, most liquid DeFi platforms, but since anyone can list tokens, users must still DYOR (do your own research).

 

Pros:
Trusted, decentralized platform with massive liquidity and battle-tested smart contracts.

Cons:
High gas fees on Ethereum mainnet during peak times.
