Step-by-Step Guide: How to Swap Tokens BVVB on Polygon (QuickSwap / Uniswap)

 To safely exchange tokens on the Polygon network (for example, swapping POL for USDT or a niche token like BVVB), the most convenient options are decentralized exchanges (DEXs) like QuickSwap (the primary native DEX on Polygon) or Uniswap (Polygon).

This guide applies to both platforms.

Prerequisites

Before you begin, ensure you have completed two basic steps:

1. Network Selection: Your Web3 wallet (MetaMask, Rabby Wallet, Trust Wallet, etc.) must be set to the Polygon network.

2. Gas Fees: You need a small balance of the native coin POL (formerly MATIC) to cover transaction fees (gas). Without POL, transactions cannot be processed.

Step-by-Step Exchange Process

1. Go to the Official DEX Website Open your browser and navigate to the official exchange address:

   • QuickSwap: quickswap.exchange

   • Uniswap: app.uniswap.org

   Always double-check the URL in your browser’s address bar to avoid phishing websites.

2. Connect Your Web3 Wallet Click the "Connect Wallet" button in the top right corner. Select your wallet provider (e.g., MetaMask) from the list and approve the connection in the pop-up window.

3. Select the Trading Pair Navigate to the Swap tab:

   • In the "You pay" field, select the token you want to exchange (e.g., POL).

   • In the "You receive" field, select the token you want to buy.

   Important: If the token you want isn’t listed, locate its official smart contract address on trusted sites like CoinGecko or CoinMarketCap, paste the contract address into the search bar, and click "Import".

4. Adjust Slippage Tolerance (Recommended for new or low-liquidity tokens) Click the gear icon (Settings) in the swap interface.

   • Popular tokens (USDT, POL, ETH): 0.1% – 0.5% is usually sufficient.

   • Low-liquidity tokens or tokens with built-in transfer taxes: May require a slippage tolerance of 1% – 5% or higher.

5. Approve the Token (Approve Allowance) If you are selling an ERC-20 token (like USDT or DAI) rather than native POL, the DEX must first request approval to access that token:

   1. Click Approve [Token Name].

   2. Confirm the spending approval request inside your wallet window.

6. Confirm the Swap

   1. Click Swap (or Preview Swap).

   2. Review the details: exchange rates, minimum received amount, and estimated fees.

   3. Click Confirm Swap.

   4. In your wallet pop-up window, check the network gas fee and click Confirm.

   5. Wait for the "Transaction Submitted" or "Swap Completed" notification (typically takes 3–10 seconds).

What to Do If the Token Doesn't Show Up in Your Wallet

After a successful swap, your balance on the DEX will update automatically, but your wallet app might not display the new token right away.

To make it visible:

1. Open your wallet and click "Import Tokens" (or the "+" icon).

2. Paste the purchased token's contract address into the Custom Token Address field.

3. Click Add Custom Token — your balance will appear immediately.
