Playing with data assets

After that, you will have an electron app and cosnole running. By default, you will have our Provider node added in the static-nodes file so you will be already connected to one. If you don't see any data assets - don't worry, they will appear after a while.

You will see a couple of data assets. For example Crypto Compare Web Api or Nethermind Tx Stream.

• Continue by placing a deposit with the unit number of your choice.

• After you make a deposit go to the Deposits tab.

When the deposit is unclonfirmed, please wait patiently for block confirmations.

Once the deposit has been confirmaed, feel free to open a data stream.

• After clicking the Open data stream button, you will be redirected to a view where you can enter requested query/stream parameters (if required) to receive the data.
