# Spot Swap

> Swap SOL, USDC, xStocks, and PreStocks through Jupiter from wallet or margin.

Spot is a Jupiter-routed swap. Use it to rotate wallet inventory, or to move margin-vault balances without opening a perp.

## Steps

1. Open **Swap**.
2. Pick pay / receive assets.
3. Choose **Wallet** or **Margin** as the source of funds when the UI offers it.
4. Review price impact, quote, slippage (default 1%), and minimum received.
5. Confirm. Wait for the history row.

Margin-balance swaps call `user_margin_swap`: the program signs the vault, Jupiter executes, and a health check runs on the new balances. Wallet swaps never touch the PDA.

PreStocks (ANTHROPIC, OPENAI) carry a real Token-2022 transfer fee (\~1%) that is included in sizing. xStocks (TSLAx, GOOGLx, AAPLx) are Token-2022 but have no transfer fee. A quote that looks "short" versus the headline price on a PreStock leg is often the fee, not a bug.
