UNISWAP-V3

    Uniswap V3 is the upgraded version of original Uniswap where decentralized exchange (DEX) trades coins like Ethereum (ETH), Wrapped Bitcoin (WBTC), and many ERC-20 tokens straight from the wallet. It's safe, open platform works for new and pro traders, offering trading without middlemen. With concentrated liquidity, users focus funds in specific price ranges for better efficiency and higher earnings, while flexible fee options suit different risk levels, making it a top DeFi platform.

    How a User Starts Using Uniswap V3

    Setting Up

    Uniswap V3 requires no account. A user needs to visit app.uniswap.org, can directly connect a wallet like MetaMask, and select the specific network (e.g., Ethereum) to the coin. Next step is to confirm the connection in their wallet, enabling trading without an email or password.

    Do Users Need ID Verification?

    Uniswap V3 doesn’t need Know Your Customer (KYC) checks, allowing a user to trade directly from their wallet with privacy and ease. However, this practice may be frowned upon by local laws which can impose restrictions in some countries according to specific country guidelines.

    Keeping a Wallet Safe

    To stay secure, a user needs to follow:

    • Keep the wallet seed phrase or private key hidden.
    • Use a hardware wallet for large amounts.
    • Activate 2FA in the wallet app if available.

    What the Website Looks Like

    Uniswap V3’s website is user-friendly. A user can see options to swap tokens, add liquidity, or view prices. They can connect the wallet with one click and select the specific network. A beginner-friendly mode simplifies first time trades.

    Adding Money to a User’s Wallet

    Using Regular Money

    Uniswap V3 doesn’t accept fiat money like USD or EUR directly. A user must:

    • Purchase ETH or USDC on an exchange like Coinbase.
    • Transfer the crypto to the wallet (e.g., MetaMask).
    • Connect the wallet to Uniswap V3 to trade.
    • The Uniswap mobile app allows crypto purchases via debit card or Robinhood Connect.

    Sending Crypto

    To add crypto:

    • A user needs to open their wallet (e.g., MetaMask).
    • Select a coin (e.g., ETH) and network (e.g., Ethereum).
    • Copy the wallet address and send crypto from another wallet or exchange.
    • The crypto arrives quickly, ready for Uniswap V3.
    • Tip: Checking the network prevents errors.

    What Are Networks?

    Uniswap V3 supports networks like Ethereum for ETH or Polygon for MATIC. Every token is designated for a specific use of the network, such as ERC20 for Ethereum tokens. A user must match the network when sending crypto to their wallet to ensure deposits succeed.

    Trading Crypto on Uniswap V3

    How to Swap Tokens

    To trade:

    • A user connects their wallet at app.uniswap.org.
    • They pick a token pair (e.g., ETH/USDC).
    • They enter the amount, adjust slippage, and confirm in their wallet.
    • Tokens appear after paying small gas fees.
      Note: Fees vary by network and market conditions.

    Trading with Pools

    Uniswap V3 uses liquidity pools instead of order books. A user trades against tokens in a pool, with prices based on supply and demand. They review “Price Impact” to avoid losses on big trades.

    Types of Trades

    • Market Swap: Trades instantly at the pool’s price.
    • Limit Order: Sets a specific price for the trade (available on some chains).

    Dealing with Small Balances

    Uniswap V3 lacks a tool for combining tiny balances. A user swaps small amounts into one token (e.g., ETH) through the swap feature, paying gas fees.

    Understanding Uniswap V3 Liquidity Pools

    Uniswap V3 pools enable trading:

    • Trading Pool: Holds tokens for swaps (e.g., ETH/USDC).
    • Provider Pool: Stores tokens a user adds to earn fees.

    Adding or Removing Tokens

    To add liquidity:

    • A user selects “Pool” and chooses a token pair.
    • They deposit equal values of both tokens in a price range.
    • They receive an NFT representing their share.
    • To withdraw, they burn the NFT to retrieve their tokens and fees.

    Taking Money Out of Uniswap V3

    Sending Crypto

    Uniswap V3 doesn’t hold funds; tokens remain in a user’s wallet. To send crypto:

    • A user opens their wallet (e.g., MetaMask).
    • They select the coin and network.
    • They enter the destination address, amount, and pay gas fees.

    Getting Regular Money

    To convert crypto to fiat:

    • A user sends tokens to an exchange like Binance.
    • They sell for fiat (e.g., USD) and withdraw to their bank.
      Note: Transferring tokens incurs gas fees.

    Common Mistakes

    • Wrong Network: Using a mismatched network (e.g., Polygon to Ethereum).
    • High Fees: Ethereum fees rise during busy times.
    • Wrong Address: Sending an incorrect wallet.
