# FAQ

> Common questions for the Stocklana Solana demo.

## Is this Solana Devnet?

No. The site is on a **Surfpool mainnet fork**. Hostname `devnet` is branding for the shared demo. RPC: [rpc-devnet.solana.vanna.finance](https://rpc-devnet.solana.vanna.finance).

## Are faucet tokens real?

No. Cheatcode mints on the fork.

## Why is Kamino stock APY zero, but Vanna is not?

Kamino's xStocks market has almost no borrowers. Vanna pools have borrowers (perps + Farm), so the kink model prints a rate.

## Do you list a perp contract?

No separate perp program. Long/short is borrow + Jupiter + margin health. You hold real tokens.

## What is max leverage?

5× is the cap in both places, but enforced differently. Farm (`lite_open`) checks it on-chain: `MAX_LEVERAGE_BPS = 50_000`. Perps has no on-chain leverage parameter at all — it's a plain deposit + borrow gated only by the account's health factor; 5× is a UI-only slider cap. Either way, health must still clear 1.10, so effective leverage is often lower than the number on the slider.

## Can I withdraw anytime (Earn)?

If the reserve has cash. High utilization blocks full redemption until repayments or liquidations free liquidity.

## Which wallets work?

Wallet Standard (Phantom, Backpack, Solflare, …) and optional Privy. Point installed wallets at the fork RPC for local use.

## Where is the program?
