Connect Wallets with dApps on Tezos

Beacon is the implementation of the wallet interaction standard tzip-10 which describes the connnection of a dApp with a wallet.

Intro

The beacon-sdk simplifies and abstracts the communication between dApps and wallets over different transport layers.

Developers that plan to develop complex smart contract interactions can use Taquito with the BeaconWallet, which uses this SDK under the hood, but provides helpful methods to interact with contracts.

Besides this Typescript SDK, we also provide SDKs for native iOS and Android Wallets:

Installation

npm i --save @airgap/beacon-sdk

Example DApp integration

const client = new DAppClient({ name: 'My Sample DApp' })

client
  .requestPermissions() // Send a permission request and automatically show UI to the user to select his favorite wallet
  .then((permissions) => {
    // Account that has been shared by the wallet
    console.log('got permissions', permissions)
  })
  .catch((error) => console.log(error))

For a more complete example, take a look at the example-dapp.html file.

Example Wallet integration

const client = new WalletClient({ name: 'My Wallet' })
await client.init() // Establish P2P connection

client
  .connect(async (message) => {
    // Example: Handle PermissionRequest. A wallet should handle all request types
    if (message.type === BeaconMessageType.PermissionRequest) {
      // Show a UI to the user where he can confirm sharing an account with the DApp

      const response: PermissionResponseInput = {
        type: BeaconMessageType.PermissionResponse,
        network: message.network, // Use the same network that the user requested
        scopes: [PermissionScope.OPERATION_REQUEST], // Ignore the scopes that have been requested and instead give only operation permissions
        id: message.id,
        publicKey: 'tezos public key'
      }

      // Send response back to DApp
      await client.respond(response)
    }
  })
  .catch((error) => console.error('connect error', error))

Development

$ npm i
$ npm run build
$ npm run test

Once the SDK is built, you can open the example-dapp.html file in your browser and try out the basic functionality. To support browser extensions as well, the file should be viewed over a webserver. You can easily start one with python -m SimpleHTTPServer 8000 and then open the file with http://localhost:8000/example-dapp.html.
