Getting staking accounts of wallet

Question

I want to receive all staking accounts for a wallet. How can I do this? I'm trying to use getParsedProgramAccounts, but don't know what should I put for data size and offset

 const accounts = await connection.getParsedProgramAccounts(
      STAKE_PROGRAM_ID,
      {
        filters: [
          {
            dataSize: 200, // number of bytes
          },
          {
            memcmp: {
              offset: 64, // number of bytes
              bytes: WALLET_KEY, // base58 encoded string
            },
          },
        ],
      },
    );

Answer 1

dataSize here seems redundant. And for offset you should use 12

Result:

const accounts = await connection.getParsedProgramAccounts(
      STAKE_PROGRAM_ID,
      {
        filters: [
          {
            memcmp: {
              offset: 12, // number of bytes
              bytes: WALLET_KEY, // base58 encoded string
            },
          },
        ],
      },
    );

Staking account is a Token Account so you can use the "getTokenAccountsByOwner" from Solana JSON RPC call : https://docs.solana.com/developing/clients/jsonrpc-api#gettokenaccountsbyowner
