Midnight Lace wallet - alpha version for devnet

There is a Midnight-enabled edition of the Lace wallet. The Midnight Lace wallet is an alpha version specifically for the devnet, functioning as a Chrome extension.

Chrome browser

You must use the Chrome web browser or its derivatives to complete web-based transactions on the Midnight devnet.

Only the Chrome browser itself is fully supported. The Midnight Lace wallet may not be able to connect to your local proof server from Chrome derivatives. If you choose to use Brave, for example, it will be necessary to disable Brave shields when running this tutorial's welcome DApp, so that the DApp (hosted at one address) can contact your local proof server (hosted on your system, at a different address) through the Midnight Lace extension.

Supported Chromium version: 119 or later.

Install Midnight Lace (alpha)​

  1. Go to the Midnight devnet releases page.
  2. Select wallet, then select midnight-lace-x.y.z-devnet (where x.y.z is the version).

  4. Unzip the file.
  5. In your Google Chrome (or derived) web browser, go to Settings > Extensions. If necessary, go to Manage Extensions, so that you see a toggle-switch for Developer mode. Enable developer mode.

  7. Click the Load unpacked button and select the folder that was created when you unzipped the Midnight Lace ZIP file.

The extension tile in your browser's list of installed extensions may show the existence of some error messages about being unable to connect to the standard set of servers. You may safely ignore these errors.

    • the Midnight network node through which transactions are to be submitted
    • the publish-subscribe (pub-sub) indexer of the blockchain, which transmits ledger updates to the wallet
    • the proof server, which generates zero-knowledge proofs of the validity of your Midnight transactions

Notice that the default proof server address points to a local instance that you have installed. This is because the proof server requires private data as inputs, and using a remote instance could compromise users' private data.

Please write down and keep your passphrase in a safe place. No one will have access to or the ability to retrieve or recover your passphrase. If you lose your passphrase, you will not be able to restore your wallet. Lace secret passphrase
