V530 is interesting. As a matter of course, reading a project's release notes is recommended. Especially in this case, as the release notes are (actually) well written.
https://nyzo.co/releaseNotes/530 To run a Micropay server, follow the same installation instructions as the Nyzo verifier, using the nyzoMicropayServer.conf file in place of the nyzoVerifier.conf file. Also, be sure to include some web content and specify the web root as micropay_data_root in /var/lib/nyzo/production/preferences. Content for an example Micropay site is available on Github.
The Micropay server uses the private key specified in /var/lib/nyzo/production/verifier_private_seed as the recipient of all Micropay transactions. Be sure that this is an existing account, as new accounts are unable to receive small transactions due to balance-list spam protections.
The Micropay client follows the same build process as all other run modes. It does not require the trusted_entry_points file. It does require specification of micropay_sender_key and micropay_max_amount_nyzos in /var/lib/nyzo/production/verifier_private_seed. The entry point for the client is co.nyzo.verifier.micropay.MicropayClient. Micropay clients for mobile systems are currently under consideration for development.
Configuration of the new Micropay functionality is seen below:

Additional details of the code changes are in the above release note.
