/ethDerivePreSignedExitMessage

Generate pre-signed exit messages for Ethereum validators. The pre-signed message allows a validator to exit without requiring an immediate on-chain transaction. Validators must all belong to the same account and be active for at least 256 epochs before a pre-signed exit message can be generated.

Specify which validators to exit using the account ID and one of the following methods -

• Public keys: Provide a list of up to 50 validator public keys.
• Validator indexes: Provide a list of validator indexes.
• Account ID & validator count: Specify the number of validators to generate messages for.
• Customer ID & validator count: Specify a customer ID and the number of validators to generate messages for.

Input example: ethDerivePreSignedExitMessage( account_id=12, type=EthExitSelectionType.PublicKey, public_keys=["0xab28...6776a", "0x9f73...5c2d"] )

Return: JSON containing the pre-signed exit messages for the specified validators.
