After collecting both signatures, create a JSON file following these steps:
Upload the bls_to_execution_change_keystore_transaction file generated in Step 1
{ "to_execution_address": "use the to_execution_address value here", "validator_index": "use the validator_index value here", "deposit_signature": "CHANGE THIS TO THE SIGNATURE HASH RECEIVED IN STEP 2", "keystore_signature": "use the signature value here" }
Important: Replace the deposit_signature with the Signature Hash you received in Step 2!
Create a pull request after which the signatures will be automatically verified
