Please how can I withdraw my DOT

Hello, I would like to ask a question now, how do I transfer my DOT on astar back to the polkadot relay chain.

Not possible now. We will be releasing the feature in a few weeks time.

FYI; This information has been published on May 27th (here) , included in our documentation, and mentioned several times in our community.

The withdrawal will be fully implemented within 1-3 weeks.
