Before creating a vault, ensure you have the following:

​
1. SOL for Transaction Fees

You need approximately 0.15 SOL for vault creation (account rent) plus additional SOL for ongoing transaction fees (strategy initialization, fund allocation, etc.).
The admin keypair pays for vault creation. The manager keypair pays for fund allocation transactions. Make sure both keypairs are funded with SOL.

​
2. Solana RPC Endpoint

A reliable Solana RPC endpoint is required for all on-chain operations. Recommended providers:

​
3. Admin and Manager Keypairs

Ranger Earn enforces role separation between admin and manager:
RoleResponsibilities
AdminAdd/remove adaptors, initialize strategies, update vault config, calibrate high water mark
ManagerAllocate funds between strategies, claim protocol rewards
Use separate keypairs for admin and manager. This limits the blast radius if one key is compromised. The admin controls vault structure; the manager controls fund movement.

​
4. Ranger Earn SDK & Dependencies

Install the SDK and required libraries: 
npm install @voltr/vault-sdk @solana/web3.js @coral-xyz/anchor

​
5. Asset Token Mint Address

Know the mint address of the SPL token your vault will accept (e.g., USDC: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v).
You can also create a vault via the UI at vaults.ranger.finance/create without installing the SDK. See Quick Start (UI).
