User Position

Reading User Position Data

Retrieve user positions, balances, and transaction history using the Kamino SDK and API.

Historical vault data is only available via the API.

Get User Positions

Retrieves user share balances across all vaults. Uses the SDK to query the user’s positions in every vault they hold shares in.

Using the SDK requires a private RPC connection or the public rate-limited RPC endpoint.

getUserPositions

import { createSolanaRpc, address } from '@solana/kit';
import { KaminoManager, getMedianSlotDurationInMsFromLastEpochs } from '@kamino-finance/klend-sdk';

const manager = new KaminoManager(
  createSolanaRpc('https://api.mainnet-beta.solana.com'),
  await getMedianSlotDurationInMsFromLastEpochs()
);

const user = address('EZC9wzVCvihCsCHEMGADYdsRhcpdRYWzSCZAVegSCfqY');
const userSharesAllVaults = await manager.getUserSharesBalanceAllVaults(user);

userSharesAllVaults.forEach((shares, vault) => {
  if (shares.totalShares.gt(0)) {
    console.log(`User shares in ${vault}:`, shares.totalShares.toString());
  }
});

Get User Vault Position

Retrieves user share balance and token value for a specific vault. Uses the SDK to calculate both shares held and their equivalent token amount.

Read a user’s vault position with the kvault-interface crate: look up their share balance and value it in underlying tokens using the vault’s current exchange rate (AUM ÷ shares issued).

Add Dependencies

[dependencies]
kvault-interface = "0.1.0"
solana-client = "2.3"
solana-pubkey = "2.1"
spl-associated-token-account = "6"

Fetch Vault State

use std::str::FromStr;

use kvault_interface::{pda, state::VaultState, Fraction, KVAULT_PROGRAM_ID};
use solana_client::rpc_client::RpcClient;
use solana_pubkey::Pubkey;
use spl_associated_token_account::get_associated_token_address;

let rpc = RpcClient::new("https://api.mainnet-beta.solana.com".to_string());

let vault_pubkey = Pubkey::from_str("HDsayqAsDWy3QvANGqh2yNraqcD8Fnjgh73Mhb3WRS5E").unwrap();
let user = Pubkey::from_str("EZC9wzVCvihCsCHEMGADYdsRhcpdRYWzSCZAVegSCfqY").unwrap();

let vault_account = rpc.get_account(&vault_pubkey).unwrap();
let vault = kvault_interface::from_account_data::<VaultState>(&vault_account.data).unwrap();

The shares mint is a PDA of the vault. Read the amount field (bytes 64..72, u64 little-endian) from the user’s shares ATA.

let (shares_mint, _bump) = pda::shares_mint(&KVAULT_PROGRAM_ID, &vault_pubkey);
let user_shares_ata = get_associated_token_address(&user, &shares_mint);

let shares_account = rpc.get_account(&user_shares_ata).unwrap();
let user_shares = u64::from_le_bytes(shares_account.data[64..72].try_into().unwrap());

This only counts shares held in the user’s share ATA. If the vault has a share farm (VaultState::vault_farm is set), most users keep their shares staked in the farm, so a complete implementation must also read the staked balance from vault.vault_farm (Kamino Farms) and add it.

Compute Exchange Rate and Position Value

let aum = Fraction::from_bits(u128::from(vault.prev_aum_sf));
let total_shares = vault.shares_issued;

println!("Vault: {vault_pubkey}");
println!("  Total AUM: {aum:.6}");
println!("  Shares issued: {total_shares}");
println!("\nUser: {user}");
println!("  Shares held: {user_shares}");

if total_shares > 0 {
    let exchange_rate = aum / Fraction::from_num(total_shares);
    let position_value = Fraction::from_num(user_shares) * exchange_rate;
    println!("  Exchange rate: {exchange_rate:.6} tokens/share");
    println!("  Position value: {position_value:.6} tokens");
} else {
    println!("  Vault has no shares issued");
}
