# Prerequisites

To integrate Klink, you'll need three things on your machine and one thing on Solana devnet.

## On your machine

| Tool                                                  | Why                                                       | Notes                                                                                                                                                                 |
| ----------------------------------------------------- | --------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [**Phantom**](https://phantom.app/) browser extension | Sign in to the dashboard, sign owner-authority operations | Owner key never leaves the extension                                                                                                                                  |
| **Node 20+** or [**Bun**](https://bun.sh/)            | Run the SDK once it's released, or run your agent code    | Bun is the project's preferred toolchain                                                                                                                              |
| A Solana **RPC endpoint**                             | Read on-chain state, submit transactions                  | Any reliable provider works, [Helius](https://helius.dev), [QuickNode](https://www.quicknode.com), [Triton](https://triton.one), or the public devnet RPC for testing |

## On Solana devnet

| Asset           | Why                                | How to get it                                                                      |
| --------------- | ---------------------------------- | ---------------------------------------------------------------------------------- |
| **Devnet SOL**  | Pays transaction fees              | `solana airdrop 1` (Solana CLI) or any [public faucet](https://faucet.solana.com/) |
| **Devnet USDC** | Test token your vault will custody | Mint a test USDC SPL token, or use one of the public devnet faucets                |

## You do NOT need

* **A custodial provider account.** Klink is non-custodial: there's no Klink account to register for.
* **A backend service.** Point your code at the hosted Klink API (`https://klink-api.onrender.com` during beta), or run your own.
* **A mainnet wallet.** Mainnet support arrives after the program audit completes: see [Roadmap](/klink-docs/reference/roadmap.md).
