You can install the{' '}

Metamask
</a>{' '}
Chrome extension Ethereum wallet. Once installed and set up, refresh this page.
<div className="pt1">

unlocked.

<h4>Parity Signer</h4>
<div>
The{' '}
<a href={constants.URL_PARITY_CHROME_STORE} target="_blank">
Parity Signer Chrome extension
</a>{' '}
lets you connect to a locally running Parity node. Make sure you have started your local Parity node
with `parity ui` or `parity --chain kovan ui` in order to connect to mainnet or Kovan respectively.
</div>
<div className="pt2">
<span className="bold">Note:</span> If you have done one of the above steps and are still seeing
this message, we might still be unable to retrieve an Ethereum address by calling
`web3.eth.accounts`. Make sure you have created at least one Ethereum address.

{Networks.Kovan} testnet (network Id: {constants.NETWORK_ID_KOVAN}) or ${constants.MAINNET_NAME}{' '}
(network Id: ${constants.NETWORK_ID_MAINNET}).
</div>
<h4>Metamask</h4>
<div>
If you are using{' '}
<a href={constants.URL_METAMASK_CHROME_STORE} target="_blank">
Metamask
