How To Connect & Register A Wallet

If you have an existing blockchain wallet, you can register the wallet to receive messages sent to that address. Visit connecting and registering wallets to learn more about connecting wallets.

Tips for registering different wallets

This guide goes through the steps of connecting and registering an Ethereum (or EVM) wallet address with Mailchain. The process is broadly similar for most wallets and protocols.

Guides for all supported protocols, web domain name services and identities can be found under Registering Wallets & Identities.

  2. A 'Signature Request' will appear in your wallet. It contains the following text:

    Message:
    Welcome to Mailchain!

    Please sign to start using this address with Mailchain. This will not trigger a blockchain transaction or cost any gas fees.

    What's happening?
    A messaging key will be registered with this address and used only for messaging. It will replace any existing registered messaging keys.

    Technical Details:
    Address: your_address
    Messaging key: a_generated_messaging_key
    Nonce: a_number

    Review the request

  3. Click 'Sign'

    review signature, then sign message

Your wallet is now verified.

Step 3: Web3 domain names and customization​

  1. Mailchain will check if any supported Web3 domain names resolve to your address.

    You can also manually search for a name if it does not appear. For more information on configuring domain name services, please see Web3 Domain Name Guides.

Step 4: Disconnect your wallet​
