Starknet

Terminal

meroctl --node node1 context create --application-id 3Hfk2VekXQ58vYHW3hUtA3mh2Rwtb1brV1brV1RKEXtfvfsf --protocol starknet

ICP

Terminal

meroctl --node node1 context create --application-id 3Hfk2VekXQ58vYHW3hUtA3mh2Rwtb1brV1RKEXtfvfsf --protocol icp

Stellar

Terminal

meroctl --node node1 context create --application-id 3Hfk2VekXQ58vYHW3hUtA3mh2Rwtb1brV1RKEXtfvfsf --protocol stellar

Ethereum

Terminal

meroctl --node node1 context create --application-id 3Hfk2VekXQ58vYHW3hUtA3mh2Rwtb1brV1RKEXtfvfsf --protocol ethereum

tip

• --application-id flag specifies the application ID to attach to the context
• --protocol flag specifies the protocol to use for the context
• --as flag creates an alias for your identity in your context, you can use it instead of the PublicKey

Admin Dashboard

Create a context using the Admin Dashboard

1. Navigate to the "Contexts" tab and click the "Start New Context" button.
2. Use the "Browse" button to select an application from the list.
3. Choose application.
4. Press "Start" to initiate the context creation process with the selected application.

Visit Admin Dashboard Page to view detailed instructions with images.

After the context is created, you will be redirected to the context dashboard. Keep this page open as you will need the Context ID later.

You have now created a new context.

To create an alias for this context, use:

Terminal

meroctl --node node1 context alias add my_context 3Hfk2VekXQ58vYHW3hUtA3mh2Rwtb1brV1RKEXtfvfsf

Next step is to invite users to join your context. Continue with invitations and joinings.
