Chainweaver kadena wallet adapter

Usage Notes

• isInstalled() assumes wallet is already open in the background
• Since chainweaver doesn't provide a way to get the wallet's accounts, you must provide the AccountsList manually. This is typically done using an interactive dialog requesting users to paste their account/pubkey into.

Example

<!-- provide a way to collect the user's account on your site -->
<dialog id="connect-chainweaver-dialog">
  <form id="connect-chainweaver-form">
    <label>
      <p>Paste your 'k:' wallet address here:</p>
      <input id="chainweaver-address-input" type="text" />
    </label>
    <button type="submit">Connect</button>
  </form>
  <p>Press esc to close</p>
</dialog>
