Prerequisites (SDK) - Ranger Earn Documentation

Before creating a vault, ensure you have the following:

1. SOL For Transaction Fees

You need roughly 0.15 SOL for vault creation rent plus additional SOL for later operations such as strategy initialization and allocation.

The admin pays for vault creation. The manager pays for allocation and most operational transactions. Fund both keypairs.

Use a stable Solana RPC endpoint. Typical providers:

Ranger Earn enforces role separation between admin and manager:

Role	Responsibilities
Admin	Add/remove adaptors, initialize strategies, update config, calibrate high water mark
Manager	Allocate funds, rebalance, claim protocol rewards

Use separate keypairs. The admin controls vault structure; the manager controls day-to-day capital movement.

Install the SDK and required libraries:

npm install @voltr/vault-sdk @solana/kit

Add @solana/web3.js only if another dependency still requires it.

Know the mint address of the SPL asset your vault accepts, for example USDC on mainnet: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v

You can also create a vault through the UI at vaults.ranger.finance/create. See Quick Start (UI).
