This endpoint is only to be used with active 0x02 validators, using this to perform initial activation deposits will result in a loss of funds.

Generate transaction data for depositing additional ETH to an active 0x02 validator.

This endpoint will generate a transaction for interacting with the canonical beacon deposit contract.

The generated transaction will contain a dummy signature and deposit data root since signature validation is skipped for active validators.

The returned transaction data must be signed and broadcast by the user.
