Users can download the Core browser extension, use Core web, or use Core mobile for Android or iOS. BTC bridging with the Avalanche Bridge™ is not supported with Metamask or any other wallet. This is because Core was custom-built to support Bitcoin and the Avalanche Bridge™ and to handle the technical problems of linking Bitcoin and EVM chains within a wallet. See here for more details on how to bridge BTC. Do not attempt to use any wallet other than the Core for BTC bridging – you may lose all your funds.
