How can we check the balance of any substrate account if we have its key?

Question

With https://www.rinkeby.io/#explorer, we can check the balance of any Ethereum address.

Is there any tool/portal for substrate address, where we can check the balance of any substrate account?

Answer 1

The most common way is using Polkadot Apps.

Because we can not ensure every chain has integrated with Subscan service, and sometimes you are under a development environment.

Example:

Navigate to chain state > system > account > type in the address > submit.

Answer 2
