UNISWAP

    Uniswap is a decentralized crypto exchange (DEX) that doesn’t require KYC checks. It uses smart contracts to let users swap tokens like Ethereum (ETH), Wrapped Bitcoin (WBTC), and other ERC-20 coins directly from their wallets. The exchange is a transparent and safe platform that suits seasonal and beginner traders. It’s a reliable, intermediary-free way to engage with the crypto market.

    History and Background

    Uniswap was launched in 2018 as an inspiration for Ethereum's Vitalik Buterin by Hayden Adams. It introduces the Automated Market Maker (AMM) model where users can directly trade through the wallet. Reason was to remove traditional order books with smart and transparent contracts. Headquartered in New York and managed by Uniswap Labs, it debuted the UNI governance token in 2020. Despite a 2024 SEC notice, Uniswap hit $2.75 trillion in trading volume by 2025, solidifying its DeFi leadership.

    Uniswap’s Global Presence and Reputation

    Uniswap is the second-biggest decentralized exchange and seventh-largest crypto platform, handling around $2.9 billion in daily trades as of April 2025. Available worldwide but blocked in countries like Iran and North Korea due to U.S. restrictions, it’s praised for strong liquidity and innovation, despite U.S. regulatory challenges.

    Why is Uniswap One of the Top Exchanges?

    Uniswap excels with its simple interface, vast token selection, and no need for intermediaries. It empowers users with self-custody and governance through UNI tokens. Features like cross-chain trading and the new Unichain blockchain make it a leader in pushing decentralized finance (DeFi) forward.

    Understanding Deposit Networks

    • Note: Gas fees vary by network and market conditions.

    Trading on Liquidity Pools
