Staking

Get Current Validators

We can stake SOL and earn rewards for helping secure the network. To stake, we delegate SOL to validators who in turn process transactions.

import { clusterApiUrl, Connection } from "@solana/web3.js";

(async () => {
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  // Get all validators, categorized by current (i.e. active) and deliquent (i.e. inactive)
  const { current, delinquent } = await connection.getVoteAccounts();
  console.log("current validators: ", current);
  console.log("all validators: ", current.concat(delinquent));
})();

Create Stake Account

All staking instructions are handled by the Stake Program. To begin, we create a Stake Account which is created and managed differently than a standard system account. In particular, we must set the account's Stake Authority and Withdrawal Authority.

Delegate Stake

Once a stake account is funded, the Stake Authority can delegate it to a validator. Each stake account can only be delegated to one validator at a time. In addition, all tokens in the account must be either delegated or un-delegated. Once delegated, it takes several epochs for a stake account to become active.

Get Delegator by Validators

Multiple accounts might have staked to a particular validator account. To fetch all the stakers, we will use getProgramAccounts or getParsedProgramAccounts API. Refer guides section for more information. The stake accounts are of 200 bytes in length and the Voter Public Key starts at 124 bytes. Reference

Deactivate Stake

At anytime after a stake account is delegated, the Stake Authority can choose to deactivate the account. Deactivation can take several epochs to complete, and is required before any SOL is withdrawn.

Get Stake Amount

Once we stake multiple tokens using multiple stake account, we can get stake amount for our specific wallet who have multiple stake account. for this we will fetch all the stake account using getProgramAccounts or getParsedProgramAccounts API. Refer guides section for more information.
