Powered by Avalanche, Core is an all-in-one operating system bringing together Avalanche apps, Subnets, bridges, and NFTs in one seamless, high-performance browser experience. Putting it another way, Core is more than a wallet. It is a curated operating system combining Wallet, Explorer, Bridge, Subnets, dApps, and more.

Getting a dApp ready to connect to Core is made simple with pre-built tools from the Core Team.

First, download and install the Core browser extension from here.

avalanche-dapp-sdks contains an example of how to connect via @web3-react/core to the Core extension specifically.

git clone [email protected]:ava-labs/avalanche-dapp-sdks.git
cd avalanche-dapp-sdks
yarn bootstrap

cd packages/web3-react-core-connector
npm start

Load "http://localhost:3000/" on your browser, and click on the "Connect Avalanche" button on the page below:


  • Check out the README to see details on how this works in more detail.

  • This Google Drive has the assets needed to create a Connect with Core button.
