Staking

Staking operations.

Initiate staking by idempotently reserving validators (0x01 credentials only).

Reserves a validator for the specific client (0x01 credentials only). Requires an idempotent key.

It takes the supplied withdrawal_pubkey, the amount which must be equal to 32,000,000,000 Gwei (32 ETH), with the following optional fields: a vault_name, a fee_recipient ETH1 address and builder_relays with the array of MEV relay addresses.

It returns the deposit payload for the user to send.

Filtering options available. Customer can choose CloudProvider(s), Region(s) and ClientType(s) (see documentation for full list of possibilities) If omitted, validators allocated as per default.

Initiate staking by idempotently reserving a unique validator with 0x02 credential.

Reserves a consolidated validator for the specific client (withdrawal credential 0x02). Requires an idempotent key. It takes an amount must equal or above 32,000,000,000 Gwei (32 ETH) and equal or below 2,048,000,000,000 Gwei (2048 ETH). It uses the supplied withdrawal_pubkey, with the following optional fields: a vault_name, a fee_recipient ETH1 address and builder_relays with the array of MEV relay addresses. It returns the deposit payloads for the user to send for each validator. Filtering options available. Customer can choose CloudProvider(s), Region(s) and ClientType(s) (see documentation for full list of possibilities) If omitted, validators allocated as per default.

Request a signed voluntary exit message with optional encryption.

Get Signed Voluntary Exit Message

This endpoint prepares a signed voluntary exit message. It won't submit the message to the consensus client.

The are two possible cases: the Default and Open PGP cyphered.

Default voluntary exit

The successful response object has two fields:exit_transaction and fork_version.

Open PGP cyphered voluntary exit

The successful response object has the same exit_transaction and fork_version fields as in the previous case. The difference is that exit_transaction is an 0x-prefixed hex encoded string which contains a signed voluntary exit message encrypted as an ASCII armored message.

The customer should manually provide their armored PGP public key, and set the cypher query parameter to openpgp.

Summary of applied rules

  • No PGP public key given and the cypher=openpgp -> 400 - bad request
  • PGP public key given and cypher is not specified -> 400 - bad request
  • PGP public key given and cypher=openpgp -> Open PGP cyphered.
  • No PGP public key given and cypher is not specified -> default.
