Avalanche

Users can <a href="https://chrome.google.com/webstore/detail/core/agoakfejjabomempkjlepdflaleeobhb?hl=en&amp;authuser=1" rel="nofollow noopener noreferrer" target="_blank">download the Core browser extension</a>, use <a href="http://core.app/bridge" rel="nofollow noopener noreferrer" target="_blank">Core web</a>, or use Core mobile for <a href="https://play.google.com/store/apps/details?id=com.avaxwallet" rel="nofollow noopener noreferrer" target="_blank">Android</a> or <a href="https://apps.apple.com/us/app/core-crypto-nft-wallet/id6443685999" rel="nofollow noopener noreferrer" target="_blank">iOS</a>. 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 <a href="https://support.avax.network/en/articles/6081464-core-extension-how-do-i-bridge-bitcoin-btc">here</a> 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.
