-## Step 5b: Extract the signature from the PSBT
-
-TODO(guggero/ffranr): Replace this step by allowing the CLI to take the signed
-PSBT instead. We can list the batch to get the asset ID of each pending asset
-and match the PSBT's input previous output to find out what signed PSBT belongs
-to what asset (in case there are multiple).

 ## Step 6: Seal the batch with the signature
 
-TODO(guggero/ffranr): Use signed PSBT instead, currently it's
-`--group_signatures <asset_id>:<signature>`, but should be
-`--signed_group_psbt` or something like that.
