• Leverage: 1-125x, set per symbol (affects new positions only)
• Margin modes: cross (shared margin) or isolated (per-position margin)
• Auth: Ed25519 signed headers — no CBOR/on-chain tx needed
• Sizes: In contract units (check exchangeInfo for precision)

Safety Rules

• Always show current position before placing opposing orders
• Warn on leverage >10x
• Show liquidation price estimate
• Require confirmation before order placement
• Check exchangeInfo for min/max order sizes and tick sizes
