getStateValidator

Overview

The getStateValidator endpoint allows you to retrieve detailed information about a specific validator in the Ethereum Beacon Chain. This information is valuable for anyone interested in understanding the status and details of a particular validator.

Parameters

Returns

• execution_optimistic (boolean): true if the response references an unverified execution payload. Optimistic information may be invalidated at a later time. If the field is not present, assume the false value.
• finalized (boolean): If the response mentions the chain's final history picked by forks, it's true. Without the field, more calls are needed to compare the requested epoch with the final checkpoint.
• data (object ): The data object contain the following structure:
  • index (string): The index of validator in validator registry
  • balance (string): The current validator balance in gwei
  • status (string): The Validator status which could have possible values of:
    • pending_initialized: When the first deposit is processed, but not enough funds are available (or not yet the end of the first epoch) to get validator into the activation queue
    • pending_queued: When validator is waiting to get activated, and has enough funds, etc. while in the queue, validator activation epoch keeps changing until it gets to the front and makes it through (finalization is a requirement here too)
    • active_ongoing: When validator must be attesting and has not initiated any exit
    • active_exiting: When validator is still active, but filed a voluntary request to exit
    • active_slashed: When validator is still active, but has a slashed status and is scheduled to exit
    • exited_unslashed: When validator has reached the regular exit epoch, is not being slashed, and doesn't have to attest any more, but cannot withdraw yet
    • exited_slashed: When validator has reached the regular exit epoch, but was slashed, have to wait for a longer withdrawal period
    • withdrawal_possible: After validator has exited, a while later is permitted to move funds and is truly out of the system
    • withdrawal_done: (not possible in phase0, except slashing full balance) having moved funds away
  • validator (object): Validator details containing the following fields:
    • pubkey (string): The validator's BLS public key, uniquely identifying them. _48-bytes, hex encoded with 0x prefix, case insensitive
    • withdrawal_crendetials (string): The root of withdrawal credentials
    • effective_balance (string): The balance at stake in Gwei
    • slashed (string): The validator is slashed (no longer active) or not
    • activation_elgibility_epoch (string): When criteria for activation were met
    • activation_epoch (string): Epoch when validator activated. FAR_FUTURE_EPOCH if not activated
    • exit_epoch (string): Epoch when validator exited
    • withdrawable_epoch (string): When validator can withdraw or transfer funds. FAR_FUTURE_EPOCH if not defined

Request Example

// Import necessary libraries and modules
import { TatumSDK, Ethereum, Network } from '@tatumio/tatum'

// Initialize the Tatum SDK with Ethereum-specific parameters
const tatum = (await TatumSDK.init) < Ethereum > { network: Network.ETHEREUM }

// Specify the state ID and validator ID
const params = {
  stateId: 'your-state-id',
  validatorId: 'validator-1',
}

// Retrieve information about a specific validator using the getStateValidator method
const validator = await tatum.rpc.beacon.v1.getStateValidator(params)

// Destroy Tatum SDK - needed for stopping background jobs
await tatum.destroy()
