Bridging Assets to Polygon on Uniswap

A guide for newer users


Uniswap, a leading decentralized exchange (DEX), enables users to swap various cryptocurrencies without the need for a central authority. With the launch of Uniswap v3, users have access to improved liquidity and trading features. However, operating across different blockchain networks can be a bit daunting, especially for those new to the crypto space. This article aims to simplify one such task: bridging USDT (Tether) from the Ethereum network to Polygon, ensuring you can trade on Uniswap while enjoying lower transaction fees and faster speeds.

Understanding Bridging

Bridging is the process of transferring tokens from one blockchain network to another. This is necessary when you want to use a token on a network different from where it's originally issued. For our purpose, we'll focus on moving USDT from Ethereum (where it's widely used) to Polygon, a network known for its efficiency and cost-effectiveness.

Why Polygon?

Polygon provides a scalable solution for Ethereum, offering faster transactions and lower fees. By bridging your USDT to Polygon, you can trade on Uniswap v3 more efficiently, making it an attractive option for users looking to optimize their trading experience.

Using MetaMask

MetaMask is a popular crypto wallet that also functions as a bridge for transferring tokens between networks. Here's how you can use MetaMask to bridge your USDT:

  1. Visit the MetaMask Bridge Portal: Go to to access the bridging feature.

  2. Select Networks: Choose the network your USDT is currently on as the "From" network (likely Ethereum) and select "Polygon" as the "To" network.

  3. Specify the Token and Amount: Select USDT as the token you wish to bridge under "You Send" and the amount you're transferring. The "You Receive" section will automatically populate with USDT on the Polygon network, based on the "To" network selection.

  4. Confirm and Complete the Bridge: Follow the prompts to approve the transaction in your MetaMask wallet. There might be a network fee associated with the transfer, so ensure you have enough ETH for the transaction.

Bridging Directly with Polygon

If you prefer not to use MetaMask or wish to explore other options, Polygon's own bridge offers a straightforward alternative:

  1. Navigate to Polygon Bridge: Visit to access the official Polygon bridge interface.

  2. Connect Your Wallet: Follow the instructions to connect your wallet to the platform. This could be MetaMask, WalletConnect, or another compatible wallet.

  3. Select the Token and Destination: Choose USDT as the token you wish to bridge, specify the amount, and confirm Polygon as the destination network.

  4. Complete the Bridging Process: Initiate the transfer and approve the transaction from your wallet. Wait for the bridging process to complete, which may take a few minutes.

Setting the Network on Uniswap

After bridging your USDT to Polygon, you need to switch your network on Uniswap (or your chosen market maker):

  1. Access Uniswap: Go to the Uniswap interface.

  2. Change the Network: Look for a network selection option, usually found in the wallet connection area. Select "Polygon" to switch networks.

  3. Start Trading: With your USDT on Polygon and the network set correctly, you're ready to trade on Uniswap v3.
