🔗Bitcoin ➡️ EVM chains

Bridging BTC tokens from the Bitcoin network to the Ethereum network as an example:

1. Open the UniPort official website, click on "Connect Wallet" in the upper right corner, select BTC network, and connect the Unisat/OKX wallet extension;

   

   

2. In the "Choose Token" menu, select BTC, input the quantity of BTC to be cross-chained to Ethereum, and the Ethereum receiving address, then click "Transfer";

   

   

3. Click "Confirm & Send" to confirm the transaction;

   

4. You can view the transaction history in the "Activity" menu.

   

Precautions：

Due to the unique characteristics of ARC20 assets, where each token is represented by Satoshis, users may encounter their balance displaying as zero during cross-chain transfers. However, the assets remain secure and there is no need for concern.

For example, if a user has a balance of 6000 QUARK on the Bitcoin network and initiates a cross-chain transaction to transfer 2000 QUARK, their wallet's QUARK balance may temporarily show as zero. Once the transaction is successfully completed, the wallet's QUARK balance will automatically update to the correct amount of 4000.
