Stake ETH
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Request
the amount (in wei) to stake. For '0x01' validators it must be a multiple of 32 ETH. For '0x02' validators any amount in [32, 2048] ETH is accepted; top-ups require at least 1 ETH and the validator's combined balance must stay under 2048 ETH.
Ethereum withdrawal credential type. Accepted values: "0x01" (deprecated, legacy, rewards above 32 ETH are swept and do not compound), "0x02" (Pectra upgrade, rewards auto-compound, max effective balance 2048 ETH, only this should be used). Defaults to "0x01" for figment and "0x02" for p2p. p2p only supports "0x02".
Only in case of top-ups specify the validatorId to top-up. If no validator is specified a new one is created instead. Top-ups are only compatible with "0x02" withdrawal credentials validators.
