Develop on the Test Network

The Public Test Network is the pre-production test network of the Open Charging Network.

It should be used to test services and features in a robust quality assurance environment. To develop on the test network, you can connect to an OCN test node and the OCN Registry that is deployed on the Volta Test Network. See more details on this below:

• OCN Registry on Volta Test Network

• Connect your service to an OCN test node

The Volta Test Network is the pre-production test network (testnet) of the Energy Web Chain. It is the blockchain equivalent of a test server or test environment in traditional software development.

The for the test network can be found on Volta under the following public key: 0xd57595D5FA1F94725C426739C449b15D92758D55.

You can view transactions and the log history for this contract on the Volta Block Explorer . If you're unfamiliar with the Block Explorer, you can read more .

The Public Test Network of the Open Charging Network provides you with some public test OCN Nodes that you can use for testing the features of the Open Charging Network.

The following test OCN test nodes are currently known to Energy Web Foundation:

• eMobilify GmbH with OCN Identity 0x4174161e7B8f137De780C024D0e988f4039F8C70 - You can obtain a for this node here: Temporarily unavailable - By using the Public Test node provided by eMobilify GmbH, you accept the Terms&Conditions and Data Protection Guidelines by eMobilify GmbH. Please visit the to learn more, or reach out to

• Elaad NL with PublicURL (Reach out to to obtain the OCN Identity and the registration token)

Follow the steps outlined in the in order to connect your service to one of the nodes listed above.

The Public Test Network should give you the option to test your OCN Node operation in a QA environment.

The OCN-Registry for the Public Test Environment can be found on the under the following public key: 0xd57595D5FA1F94725C426739C449b15D92758D55

Follow the steps outlined in the for guidance on how to run a node.

The Open Charging Network provides mock OCPI parties for exchanging simple OCPI requests over the Public Test Network.

One Mock CPO and one Mock eMSP are available on the Public Test Network (i.e. registered in the Registry contract that is deployed on the Volta Testnet)

Please note that the functionality of both mock parties is limited, and does not implement or cover all OCPI modules and use-cases. Details can be found on the Bitbucket repository: .
