​
Update Via UI

The simplest path is the Ranger manage page: 
https://vaults.ranger.finance/manage/<VAULT_PUBKEY>

​
Update Via SDK

The v2 SDK uses getUpdateVaultConfigInstructionAsync, one field at a time. 
import fs from "fs";
import { createKeyPairSignerFromBytes } from "@solana/kit";
import {
  getUpdateVaultConfigInstructionAsync,
  findVaultLpMintPda,
  VaultConfigField,
} from "@voltr/vault-sdk";

const adminSigner = await createKeyPairSignerFromBytes(
  Uint8Array.from(JSON.parse(fs.readFileSync("/path/to/admin.json", "utf-8")))
);
const vault = "YOUR_VAULT_ADDRESS" as const;

​
Update A u64 Field

const data = new Uint8Array(Buffer.alloc(8));
Buffer.from(data).writeBigUInt64LE(18_446_744_073_709_551_615n, 0);

const updateIx = await getUpdateVaultConfigInstructionAsync({
  admin: adminSigner,
  vault,
  field: VaultConfigField.MaxCap,
  data,
});

​
Update A Fee Field

const feeData = new Uint8Array(Buffer.alloc(2));
Buffer.from(feeData).writeUInt16LE(1_500, 0);

const updateIx = await getUpdateVaultConfigInstructionAsync({
  admin: adminSigner,
  vault,
  field: VaultConfigField.ManagerPerformanceFee,
  data: feeData,
});

​
Management Fee Special Case

For ManagerManagementFee and AdminManagementFee, append the vault LP mint account to the final instruction accounts: 
const [vaultLpMint] = await findVaultLpMintPda({ vault });
The maintained admin-update-vault-config.ts scripts show the exact extra-account pattern used in production.

​
Update Manager

Manager and pending-admin changes use a 32-byte encoded address as the payload.

​
Serialization Reference

Field TypeEncoding
u648 bytes, little-endian
u162 bytes, little-endian

Be careful when changing manager authority. Once moved, the old manager key can no longer operate the vault.
