Ethereum-based protocols

Uniswap is a decentralized cryptocurrency exchange protocol built on the Ethereum blockchain. It enables the automated trading of digital assets through smart contracts, eliminating the need for intermediaries or centralized order books. Uniswap facilitates cryptocurrency tokens swaps using liquidity pools contributed by users.

CryptoKitties is a blockchain game developed by Canadian studio Dapper Labs. The game allows players to buy, sell, and create non-fungible tokens (NFTs) using Ethereum. These NFTs represent virtual cats. The game's popularity in December 2017 congested the Ethereum network, causing it to reach an all-time high in the number of transactions and slowing it down significantly.
