WalletConnect kadena wallet adapter

Usage Notes

• Requires passing in signClientOptions, networkId and walletConnectModalController to connect()
  • signClientOptions: WalletConnect SignClient configuration options such as relayURL and dapp metadata
  • walletConnectModalController: an object that controls the opening and closing of a WalletConnect QR code modal for users to scan. @web3modal/standalone's Web3Modal class can be used here.
• A previously saved pairingTopic can be passed to connect() to resume an existing connection
• None of the WalletConnect wallets implement quicksign yet

Example

import { PactCommand } from "@kadena/client";
/**

 * `events` npm package must be installed
 * else Web3Modal will throw
 * `events_1.EventEmitter is not a constructor`
 *
