# Canonical Withdrawal Finalization

> Why a Sophon-to-Ethereum canonical withdrawal is not immediate

<Warning>
  The Sophon Chain is being wound down and deposits are disabled. Start withdrawals
  at [claim.sophon.com](https://claim.sophon.com) and complete them before the final
  decommissioning date.
</Warning>

A canonical withdrawal from Sophon to Ethereum is not immediately claimable. The
Sophon transaction must be included in a batch, and the corresponding chain state
must be finalized and proven on Ethereum before the withdrawal can be completed.

The wait depends on batch processing, proof generation, and Ethereum finalization.
Actual timing can vary, so follow the status shown by the claim portal rather than
assuming a fixed completion time.

## Typical flow

1. Initiate the Sophon-to-Ethereum withdrawal through
   [claim.sophon.com](https://claim.sophon.com).
2. Wait for the Sophon batch and proof to be finalized on Ethereum.
3. Return to the portal when the withdrawal is ready.
4. Submit the final claim transaction on Ethereum.
