I would like to ask you how to subscribe events from Polkadot blockchain? I am writing a rust application and I need this functionality there.

Is the using Substrate the right direction to achieve that?

Thanks in advance!

subxt has your back. Here's an example:

https://github.com/paritytech/subxt/blob/master/examples/examples/subscribe_all_events.rs

(Events are just the system.events state at a certain block, so if you know the block hash you're after you can retrieve them by via a storage query)

(if you want to subscribe to blocks there's an example in the PRs)

  • Broken link at this point. I couldn't find a current example in the repo that seems to demonstrate how to subscribe to events. Jul 11, 2023 at 13:02
  • I take that comment back, sorry. The example as of time of writing is here: github.com/paritytech/subxt/blob/… within the block subscription example. Jul 11, 2023 at 14:06
