Bridging Your Assets to U2U Chain with the U2U Bridge

The U2U Chain supports a variety of decentralized applications (dApps), enabling seamless interactions within its ecosystem. However, it’s important to note that transaction fees on the U2U Chain are paid using the U2U token. To use dApps on the U2U Chain, you must deposit some U2U tokens into the network to cover gas fees. Here's how you can do it:

Depositing Assets to the U2U Chain

To transfer assets such as U2U, ERC-20, ERC-721, or other compatible tokens to the U2U Chain, follow these steps:

Step 1: Connect Your MetaMask Wallet to the U2U Bridge

1. Visit the U2U Bridge and click the MetaMask icon to connect your wallet.

2. Ensure your default network is set to Ethereum Mainnet or another compatible Layer 1 network.

3. Confirm the connection request in MetaMask.

   • Once connected, the bridge will automatically fetch your asset balances on the source network.

   • Your assets on Ethereum (Layer 1) will be displayed as L1 balances, while bridged assets on the U2U Chain will appear as L2 balances.

Step 2: Select the Assets to Bridge

1. Choose the token and amount you wish to bridge.

2. Click "Move funds to U2U Chain" and follow the MetaMask prompts.

3. Wait for the transactions to be confirmed on the blockchain. Note that you will incur transaction fees for the source network.

That’s it! Your assets are now successfully bridged to the U2U Chain, allowing you to interact with the various dApps within its ecosystem.

Withdrawing Assets from the U2U Chain

If you wish to withdraw your assets from the U2U Chain (L2) to Ethereum (L1) or another compatible network, simply reverse the depositing steps:

1. Visit the U2U Bridge and connect your MetaMask wallet to the U2U Chain.

2. Set the sender network to the U2U Chain (From: U2U Solaris Mainnet) and the recipient network to Ethereum (To: Ethereum Mainnet).

3. Select the token and amount you wish to withdraw.

4. Follow the MetaMask prompts and ensure you have some U2U tokens for gas fees.

That’s it! Your assets are now successfully withdrawn from the U2U Chain.
