    Domain Verification Checker

    + +

    This tool allows you to verify that domain verification is properly configured.

    +

    Enter the manifest found in your validator-keys.json file. Do not confuse this with your validator's secret key.

    +

    To do this with the validator-keys-tool use the following command:

    + 
    $ validator-keys show_manifest hex
    +
    +
    +
    + +
    +
    +
