You can send main tokens from the Luniverse Console.
For details, please refer to the link below:
Sending Main Tokens through API
You can sen main tokens via API, not using the console.
Delegation Contract. To pay the fee, you must be registered on the whitelist, and only the registered EOA can send tokens. Therefore, if EOA is not registered on the whitelist, it must be registered through the whitelist registration API.
The EOA includes the DEOA. The only difference is to sign whether via the API or directly in the signing process.
Running Whitelist Registration API
curl -X POST 'https://api.luniverse.io/mx/v2.0/delegation-contract/whitelist' \
You can find the “mainEnvironmentId” in the chain detail page URL of the console.
You need an authentication token to make API calls. To issue authentication tokens for API calls, see below. We will skip explaining about issuing authentication tokens in the following API explanation.
