Frequently asked questions about Nethermind Data Marketplace - Consumer

How can I connect to a provider?

There is separate documentation about connecting to a provider.

What's the difference between Unit and Time type data asset?

In unit type, when you place a deposit, you are given access to the value of units based on how much units you can consume with this deposit eg. one unit price is 1 xDai, and if you place a deposit with an amount of 100 xDai, you get access to consume 100 units.

In time type, you pay for time under which you can consume units, eg. provider has time data asset with one second for 1 xDai, and if you place a deposit for 100 xDai, you can consume those units for 100 seconds. Keep in mind that you pay only for seconds which you actually used, hence, if you were consuming units for 30 seconds but had deposit for 100 seconds, you will be refunded for 70 seconds.

I can't make a deposit for an asset.

Check if you have connection with provider or if provider hasn't closed the asset. Or maybe you have sufficient balance on your account.

Provider closed an asset and I still haven't received refund.

In most scenarios, this is due to the refund policy which holds deposit value in the contract for 24 hours more before the refund is processed. If after this time you still haven't received the refund, please contact with NDM support.

What happens when deposit expires?

In case when you have any unused units - you will received a refund for them.
