Core mobile now offers the ability to bridge BTC to the Avalanche® network.
Note:
BTC Bridging is ONLY available through Core mobile, Core extension, and at core.app.
The “.b” indicates that the token was bridged from the Bitcoin network, just as Avalanche Bridge™ tokens bridged from Ethereum end in “.e”.
Core mobile will need to have Bitcoin (BTC) in Core mobile before using the bridge.
Users can use the address found in the following screen of the portfolio page to load BTC prior to bridging.
Bridging BTC to Avalanche
1. Select the network to move assets. The image below shows the three possible networks (Avalanche, Ethereum, and Bitcoin). In our example, we will select “Bitcoin.”
2. Enter the amount of Bitcoin to Bridge over, and select "Transfer."
Once the BTC has been successfully bridged over, it will appear in your Bitcoin Portfolio.
As a reminder, there are two distinct types of fees for the BTC Bridge:
Network fees, known as BTC transaction (Tx) fees for the BTC Bridge.
Fees that are charged by the Bridge to the user (also known as Bridge Toll).
If the transaction is not going through, this may be due to an inadequate amount of BTC to cover the fees. Please check before sending to ensure there is enough BTC to cover the fees.
Note:
Bitcoin that is bridged will now appear with a ".b" designation representing the bridged asset.
The Core interface will need time to update your newly bridged asset.
